YEAR FROM THE DATE OF PURCHASE, BUT IN NO EVENT TO EXCEED (18) EIGHTEEN MONTHS FROM THE DATE
OF SHIPMENT FROM THE FACTORY.
Jackson MSC agrees under this warranty to repair or replace , at its discretion, any original part which fails under normal use due to faulty
material or workmanship during the warranty period, providing the equipment has been unaltered, and has been properly installed, maintained and operated in accordance with the applicable factory instruction manual furnished with the machine and the failure is reported to
the authorized service agency within the warranty period. This includes the use of factory specified genuine replacement parts, purchased
directly from a Jackson authorized parts distributor or service agency. Use of generic replacement parts may create a hazard and void warranty certification.
The labor to repair or replace such failed part will be paid by Jackson MSC, within the continental United States, Hawaii and Canada, during
the warranty period provided a Jackson MSC authorized service agency, or those having prior authorization from the factory, performs the
service. Any repair work by persons other than a Jackson MSC authorized service agency is the sole responsibility of the customer. Labor
coverage is limited to regular hourly rates, overtime premiums and emergency service charges will not be paid by Jackson MSC.
Accessory components not installed by the factory carry a (1) one year parts warranty only. Accessory components such as table limit switches, pressure regulators, pre rinse units, etc. that are shipped with the unit and installed at the site are included. Labor to repair or replace
these components is not covered by Jackson MSC.
This warranty is void if failure is a direct result from shipping, handling, fire, water, accident, misuse, acts of god, attempted repair by unauthorized persons, improper installation, if serial number has been removed or altered, or if unit is used for purpose other than it was originally intended.
TRAVEL LIMITATIONS
Jackson MSC limits warranty travel time to (2) two hours and mileage to (100) one hundred miles. Jackson MSC will not pay for travel time
and mileage that exceeds this, or any fees such as those for air or boat travel without prior authorization.

NEGLIGENCE, WITH RESPECT TO THE GOODS OR SERVICES COVERED HEREUNDER, SHALL IN NO CASE EXCEED THE PRICE
OF THE GOODS OR SERVICES OR PART THEREOF WHICH GIVES RISE TO THE CLAIM.

of installation. In addition, the warranty will only cover the replacement of wear items such as curtains, drain balls, door guides or gaskets
during the first 30 days after installation. Also, not covered are conditions caused by the use of incorrect (non-Commercial) grade detergents,

INSTALLATION & OPERATION
INSTRUCTIONS

25

SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS
INSTALLATION INSTRUCTIONS
NOTE: THE INSTRUCTIONS PROVIDED HEREIN, UNLESS OTHERWISE SPECIFIED ARE FOR THE DISHMACHINES ONLY. THERE ARE SEPARATE DIRECTIONS FOR THE GAS BOOSTER.
VISUAL INSPECTION: Before installing the unit, check the container and machine for damage. A damaged container is an indicator that there may be some damage to the machine. If there is damage to both the container and machine, do not throw away
the container. The dishmachine has been inspected and packed at the factory and is expected to arrive to you in new, undamaged condition. However, rough handling by carriers or others may result in damage to the unit while in transit. If such a situation occurs, do not return the unit to Jackson; instead, contact the carrier and ask them to send a representative to the site to
inspect the damage to the unit and to complete an inspection report. You must contact the carrier within 48 hours of receiving
the machine. Also, contact the dealer through which you purchased the unit.
UNPACKING THE DISHMACHINE: The machine should be unboxed and removed from shipping pallet prior to being installed.
Open the front door and remove all of the packing materials. Once unpacked, ensure that there are no missing parts from the
machine. This may not be obvious at first. If it is discovered that an item is missing, contact Jackson immediately.
LEVEL THE DISHMACHINE: The dishmachine is designed to operate while being level. This is
important to prevent any damage to the machine during operation and to ensure the best results
when washing ware. The unit comes with adjustable bullet feet, which can be turned using a pair
of channel locks or by hand if the unit can be raised safely. Ensure that the unit is level from side
to side and from front to back before making any connections. You will be able to adjust the overall height of the unit by turning the bullet feet from between 75-1/2” to 76-1/2”.
PLUMBING THE DISHMACHINE: All plumbing connections must comply with all applicable local,
state, and national plumbing codes. The plumber is responsible for ensuring that the incoming water line is thoroughly flushed
prior to connecting it to any component of the dishmachine. It is necessary to remove all foreign debris from the water line that
may potentially get trapped in the valves or cause an obstruction. Any valves that are fouled as a result of foreign matter left in
the water line, and any expenses resulting from this fouling, are not the responsibility of the manufacturer.
Water hardness should be a maximum of 6 grains per gallon. Harder water should be treated prior to using the machine. Iron
in the water supply can cause staining. A filter designed to remove iron from the supply water is highly recommended for supplies in excess of 0.1 ppm (parts per million).
CONNECTING THE DRAIN LINE: The drain for the models covered in this
manual are gravity discharge drains. All piping from the machine to the drain Adjusting screw
must be a minimum 1 1/2” NPT and shall not be reduced. There must also be Locking nut
an air gap between the machine drain line and the floor sink or drain. If a grease
trap is required by code, it should have a flow capacity of 30 gallons per minute.
WATER SUPPLY CONNECTION: Ensure that you have read the section entitled “PLUMBING THE DISHMACHINE” above before proceeding. The supply
water temperature must meet the minimum requirements listed on the machine
data plate. Install the water supply line (1/2” pipe size minimum) to the dishmachine line strainer. It is recommended that a water shut-off valve be installed in
the water line between the main supply and the machine to allow access for service. The water supply line is to be capable of 25 PSI “flow” pressure at the recommended temperature indicated on the data plate.

Incoming Plumbing Connection

If the water level is too low or too high, check the incoming water pressure. It should be 20 ± 5 PSI. Too high of pressure results
in too much water; too low of pressure results in too little water. To adust the regulator, loosen the nut at the top, this will allow
you to screw or unscrew the adjustment. With a screwdriver, turn the adjuster clockwise to increase pressure or counter clockwise to decrease it.
Do not confuse static pressure with flow pressure. Static pressure is the line pressure in a “no flow” condition (all valves and
services are closed). Flow pressure is the pressure in the fill line when the fill valve is opened during the cycle.
It is also recommended that a shock absorber (not supplied) be installed in the incoming water line. This prevents line hammer
(hydraulic shock), induced by the solenoid valve as it operates, from causing damage to the equipment.

SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS
INSTALLATION INSTRUCTIONS (CONTINUED)
STEAM LINE CONNECTIONS: Some machines covered in this manual are designed to use low pressure steam as a source
of heat for wash tank water. The machines come with lines by which outside source steam needs to be connected. Connect all
incoming steam lines in accordance with the steam booster manufacturer’s instructions. Ensure that all applicable codes and
regulations are adhered to. See machine data plate for information concerning steam flow pressure.
GAS CONNECTIONS: Some machines covered in this manual are designed to use gas as an outside source of heat for wash
tank water. The machines come with connections by which an outside source needs to be connected. Connect all incoming gas
lines in accordance with the gas booster manufacturer’s instructions. Ensure that all applicable codes and regulations are
adhered to.
PLUMBING CHECK: Slowly turn on the water supply to the machine after the incoming fill line and the drain line have been
installed. Check for any leaks and repair as required. All leaks must be repaired prior to placing the machine in operation.
ELECTRICAL POWER CONNECTION: Electrical and grounding connections must comply with the applicable portions of the
National Electrical Code ANSI/NFPA 70 (latest edition) and/or other electrical codes.
Disconnect electrical power supply and place a tag at the disconnect switch to indicate that you are working on the
circuit.
The dishmachine data plate is located on the right side and to
the front of the machine. Refer to the data plate for machine
operating requirements, machine voltage, total amperage load
and serial number.

block. Install the grounding wire into the lug provided. Tighten
the connections. It is recommended that “DE-OX” or another
similar anti-oxidation agent be used on all power connections.
VOLTAGE CHECK: Ensure that the power switch is in the OFF
position and apply power to the dishmachine. Check the incoming power at the terminal block and ensure it corresponds to the
voltage listed on the data plate. If not, contact a qualified service
agency to examine the problem. Do not run the dishmachine if
the voltage is too high or too low. Shut off the service breaker
and mark it as being for the dishmachine. Advise all proper personnel of any problems and of the location of the service breaker. Replace the control box cover and tighten down the screws.

Terminal Block

Incoming Power Connection

VENTILATION OF DISHMACHINE: The dishmachine should be located with provisions for venting into an adequate exhaust
hood or ventilation system. This is essential to permit efficient removal of the condensation exhaust. Ensure that the exhaust
system is acceptable in accordance with all applicable codes and standards.
NOTE: Any damage that is caused by steam or moisture due to improper ventilation is NOT covered under the warranty.
This units covered in this manual have the following exhaust requirements:

SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS
DELIMING OPERATIONS
DELIMING OPERATIONS: In order to maintain the dishmachine at its optimum performance level, it will be required to remove
lime and corrosion deposits on a frequent basis. A deliming solution should be available from your detergent supplier. Read and
follow all instructions on the label of the deliming solution.
To proceed with the deliming operation, fill the dishmachine and add the correct amount of deliming solution as recommended
by the deliming solution manufacturer. The water capacity of the various tanks of the dishmachine can be verified on the specification sheet(s) of this manual.
Perform the following operations to delime the dishmachine:
1. Turn the NORMAL/DELIME switch on the back of the control box to the DELIME position.
2. Disconnect or turn off all chemical feeder pumps.
3. Close all doors (after adding the deliming solution).
4. Run the machine for the recommended period of time.
5. Turn the unit off and open the doors.
6. Wait five minutes, then inspect the inside of the machine. If the machine is not delimed, run another time cycle as per the
deliming solution’s instructions.
7. When clean, drain and re-fill the machine.
8. Run in MANUAL for 10 minutes to remove residual deliming solution.
9. Drain and re-fill the machine.
This equipment is not recommend for use with deionized water or other aggressive fluids. Use of deionized water or
other aggressive fluids will result in corrosion and failure of materials and components. Use of deionized water or
other aggressive fluids will void the manufacturer's warranty.

SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS
SIDE LOADER INSTALLATION & OPERATION INSTRUCTIONS

This accessory assists in the delivery of a full dish rack from the break down (scrapping) table to the dishmachine. It will convert the direction of travel 90°. Since the Side Loader is shipped mounted on the conveyor dishwasher there is no additional
installation required for this option. As it is operated mechanically by the dishwasher it does not require any plumbing or electrical connections.
This Side Loader does not require or add any additional electrical or mechanical devices to the unit which could create operational or maintenance problems. As designed the drive mechanism is powered by the conveyor drive motor on the dishmachine. An extension on the pawl bar provides the drive to push the racks into the unit.
PREPARATION: Before proceeding with the start-up of the unit, verify that the Side Loader pan strainer is installed.
WARE PREPARATION: Proper preparation of ware will help ensure good results and less re-washes. If not done properly, ware
may not come out clean and the efficiency of the dishmachine will be reduced. It is important to remember that a dishmachine
is not a garbage disposal and that simply throwing unscraped dishes into the machine simply defeats the purpose altogether
of washing the ware. Scraps should be removed from ware prior to being loaded into a rack. Pre-rinsing and pre-soaking are
good ideas, especially for silverware and casserole dishes. Place cups and glasses upside down in racks so that they do not
hold water during the cycle. The dishmachine is meant not only to clean, but to sanitize as well, to destroy all of the bacteria
that could be harmful to human beings. In order to do this, ware must be properly prepared prior to being placed in the machine.
WASHING A RACK OF WARE: Once a rack is fully loaded it should be positioned against the front of the dish table. The rack
should then be moved into the Side Loader until it activates the actuator switch. Once the the machine is started, it should pull
the rack through the machine and push it out the unload end. Once a rack has started through, you may put another rack in.
OPERATIONAL INSPECTION: Based upon usage, the pan strainer may become clogged with soil and debris as the workday
progresses. Operators should regularly inspect the pan strainer to ensure it has not become clogged. If the strainer does
become clogged, it will reduce the washing capability of the machine. Instruct operators to clean out the pan strainer at regular intervals or as required by work load.
SHUTDOWN AND CLEANING: At the end of the workday, remove the pan strainer and clean as required. Wipe out the inside
of the Side Loader and then reinsert the strainer.

DISHMACHINE OPERATING INSTRUCTIONS
PREPARATION: Before proceeding with the start-up of the unit, verify the following:
1. Close door(s) on dishmachine.
2. Close the drain valve(s).
POWER UP (ELECTRICALLY-HEATED MODELS): To energize the unit, turn on the power at the service breaker. The voltage should have been previously verified as being correct. If not, the voltage will have to be verified.
POWER UP (GAS-HEATED MODELS): To energize the unit, turn on the power at the service breaker. The voltage should have
been previously verified as being correct. If not, the voltage will have to be verified. Ensure that the gas service is connected
and that gas is flowing to the machine. Without gas, the water will not reach the required minimum temperatures that the
machine is designed to operate at.
POWER UP (STEAM-HEATED MODELS): To energize the unit, turn on the power at the service breaker. The voltage should
have been previously verified as being correct. If not, the voltage will have to be verified. Ensure that the steam service is connected and that steam is flowing to the machine. Without steam, the water will not reach the required minimum temperatures
that the machine is designed to operate at.
FILLING THE WASH TUB: Ensure that the delime switch is in the NORMAL position, and place the power switch into the ON
position. The machine should fill automatically and shut off when the appropriate level is reached (just below the pan strainer).
The wash tub must be completely filled before operating the wash pump to prevent damage to the component. Once the wash
tub is filled, the unit is ready for operation.
Machines equipped with prewash sections should not be run without water in those sections. This can cause
damage to components.
WARE PREPARATION: Proper preparation of ware will help ensure good results and less re-washes. If not done properly, ware
may not come out clean and the efficiency of the dishmachine will be reduced. It is important to remember that a dishmachine
is not a garbage disposal and that simply throwing unscraped dishes into the machine simply defeats the purpose altogether
of washing the ware. Scraps should be removed from ware prior to being loaded into a rack. Pre-rinsing and pre-soaking are
good ideas, especially for silverware and casserole dishes. Place cups and glasses upside down in racks so that they do not
hold water during the cycle. The dishmachine is meant not only to clean, but to sanitize as well, to destroy all of the bacteria
that could be harmful to human beings. In order to do this, ware must be properly prepared prior to being placed in the machine.
DAILY MACHINE PREPARATION: Refer to the section entitled “PREPARATION” at the top of this page and follow the instructions there. Afterwards, check that all of the chemical levels are correct and/or that there is plenty of detergent available for the
expected workload.
WASHING A RACK OF WARE: To wash a rack, simply slide a rack of soiled ware into the load end of the machine. Once the
the machine is started, it should pull the rack through the machine and push it out the unload end. Once a rack has started
through, you may put another rack in.
OPERATIONAL INSPECTION: Based upon usage, the pan strainers may become clogged with soil and debris as the workday progresses. Operators should regularly inspect the pan strainers to ensure they have not become clogged. If the strainers
do, they will reduce the washing capability of the machine. Instruct operators to clean out the pan strainers at regular intervals
or as required by work load.
NOTE: On units equipped with prewash sections (AJ-66 & AJ-80), operators should also take the time to inspect the prewash
section strainers and clean them as required by workload.

SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS
DETERGENT CONTROL
Detergent usage and water hardness are two factors that contribute greatly to how efficiently your dishmachine will operate.
Using detergent in the proper amount can become, in time, a source of substantial savings. A qualified water treatment specialist can tell you what is needed for maximum efficiency from your detergent, but you should still know some basics so you’ll
understand what they are talking about.
First, you must understand that hard water greatly effects the performance of the dishmachine. Water hardness is the amount
of dissolved calcium and magnesium in the water supply. The more dissolved solids in the water, the greater the water hardness. Hard water works against detergent, thereby causing the amount of detergent required for washing to increase. As you
use more detergent, your costs for operating the dishmachine will increase and the results will decrease. The solids in hard
water also may build-up as a scale on wash and rinse heaters, decreasing their ability to heat water. Water temperature is
important in removing soil and sanitizing dishes. If the water cannot get hot enough, your results may not be satisfactory. This
is why Jackson recommends that if you have installed the machine in an area with hard water, that you also install some type
of water treatment equipment to help remove the dissolved solids from the water before it gets to the dishmachine.
Second, hard water may have you adding drying agents to your operating cycle to prevent spotting, when the real problem is
deposited solids on your ware. As the water evaporates off of the ware, the solids will be left behind to form the spotting and
no amount of drying agent will prevent this. Again, using treated water will undoubtedly reduce the occurrences of this problem.
Third, treated water may not be suitable for use in other areas of your operation. For instance, coffee made with soft water may
have an acid or bitter flavor. It may only be feasible to install a small treatment unit for the water going into the dishmachine
itself. Discuss this option with your qualified water treatment specialist.
Even after the water hardness problems have been solved, there still must be proper training of dishmachine operators in how
much detergent is to be used per cycle. Talk with your water treatment specialist and detergent vendor and come up with a
complete training program for operators. Using too much detergent has as detrimental effects as using too little. The proper
amount of detergent must be used for job. It is important to remember that certain menu items may require extra detergent by
their nature and personnel need to be made aware of this. Experience in using the dishmachine under a variety of conditions,
along with good training in the operation of the machine, can go a long way in ensuring your dishmachine operates as efficiently as possible.
Certain dishmachine models require that chemicals be provided for proper operation and sanitization. Some models even
require the installation of third-party chemical feeders to introduce those chemicals to the machine. Jackson does not recommend or endorse any brand name of chemicals or chemical dispensing equipment. Contact your local chemical distributor for
questions concerning these subjects.
Some dishmachines come equipped with integral solid detergent dispensers. These dispensers are designed to accommodate
detergents in a certain sized container. If you have such a unit, remember to explain this to your chemical distributor upon first
contacting them.
As explained before, water temperature is an important factor in ensuring that your dishmachine functions properly. The data
plate located on each unit details what the minimum temperatures must be for either the incoming water supply, the wash tank
and the rinse tank, depending on what model of dishmachine you have installed. These temperatures may also be followed by
temperatures that Jackson recommends to ensure the highest performance from you dishmachine. However, if the minimum
requirements are not met, the chances are your dishes will not be clean or sanitized. Remember, a dish can look clean, but it
may not be sanitized. Instruct your dishmachine operators to observe the required temperatures and to report when they fall
below the minimum allowed. A loss of temperature can indicate a much larger problem such as a failed heater or it could also
indicate that the hot water heater for your operation is not up to capacity and a larger one may need to be installed.
There are several factors to consider when installing your dishmachine to ensure that you get the best possible results from it
and that it operates at peak efficiency for many years. Discuss your concerns with your local chemical distributor and water
treatment specialist before there is a problem.

SECTION 3: PREVENTATIVE MAINTENANCE
PREVENTATIVE MAINTENANCE
The dishmachines covered in this manual are designed to operate with a minimum of interaction with the operator. However,
this does not mean that some items will not wear out in time. Jackson highly recommends that any maintenance and repairs
not specifically discussed in this manual should be performed by QUALIFIED SERVICE PERSONNEL ONLY. Performing maintenance on your dishmachine may void your warranty if it is still in effect, so if you have a question or concern, do not hesitate
to contact Jackson.
There are many things that operators can do to prevent catastrophic damage to the dishmachine. One of the major causes of
component failure has to do with prescrapping procedures. A dishmachine is not a garbage disposal; any large pieces of material that are put into the machine shall remain in the machine until they are either broken up (after spreading out on your ware!)
or physically removed. Strainers are installed to help catch debris, but they do no good if they are clogged. Have operators regularly inspect the pan strainers to ensure (1) that they are free of soil and debris and (2) they are laying flat in the tub.
When cleaning out strainers, do NOT beat them on waste cans. The strainers are made of metal and can be forgiving; but once
severe damage is done, it is next to impossible for the strainer to work in the way it was designed to. Wipe out strainers with
a rag and rinse under a faucet if necessary. For stubborn debris, a toothpick should be able to dislodge any obstructions from
the perforations. Always ensure that strainers are placed back in the machine before operation and that they lay flat in the tub.
You may wish to also refer to the page entitled “Detergent Control” in order to learn more about how your water hardness will
effect the performance of your machine. Hard water makes dishmachines work harder and decreases efficiency.
Again, it is important to remind operators that trying to perform corrective maintenance on the dishmachine could lead to larger problems or even cause harm to the operator. If a problem is discovered; secure the dishmachine using proper shut down
procedures as listed in this manual and contact Jackson.
Some problems, however, may having nothing to do with the machine itself and no amount of preventative maintenance is
going to help. A common problem has to do with temperatures being too low. Verify that the water temperatures coming to your
dishmachine match the requirements listed on the machine data plate. There can be a variety of reasons why your water temperature could be too low and you should discuss it with Jackson to determine what can be done.
By following the operating and cleaning instructions in this manual, you should get the most efficient results from your machine.
As a reminder, here are some steps to take to ensure that you are using the dishmachine the way it was designed to work:
1. Ensure that the water temperatures match those listed on the machine data plate.
2. Ensure that all strainers are in place before operating the machine.
3. Ensure that all wash and/or rinse arms are secure in the machine before operating.
4. Ensure that drains are closed/sealed before operating.
5. Remove as much soil from dishes by hand as possible before loading into racks.
6. Do not overfill racks.
7. Ensure that glasses are placed upside down in the rack.
8. Ensure that all chemicals being injected to machine have been verified as being at the correct concentrations.
9. Clean out the machine at the end of every workday as per the instructions in the manual.
10. Always contact Jackson whenever a serious problem arises.
11. Follow all safety procedures, whether listed in this manual or put forth by local, state or national codes/regulations.

SECTION 3: PREVENTATIVE MAINTENANCE
DRIVE MOTOR GEAR REDUCER PREVENTATIVE MAINTENANCE
Note: The maintenance procedures detailed here are manufacturer’s instructions for the WINSMITH brand of gear reducer that
is installed on the rack conveyors covered in this manual.
Lubrication & Maintenance:
Factory filling - WINSMITH speed reducers are oil filled at the factory to the proper level for the standard mounting position that you
will find it in on the unit. The oil level should be checked and adjusted (if necessary) prior to operation, using the oil level plug provided
and while the unit is oriented in its operating position.
Ambient temperature - If the operating ambient temperature is other than 51 - 95°F, then refer to the lubrication chart and refill the unit
with the correct grade based on actual ambient temperature and operating speed. See “Oil changing” below for additional information.
Oil changing - When changing the oil for any reason, it should be remembered that oils of various types may not be compatible.
Therefore, when changing to a different oil, it is recommended that the housing be completely drained and thoroughly flushed with a
light flushing oil prior to refilling with the appropriate lubricant. The oil level should be rechecked after a short period of operation and
adjusted, if necessary. When changing double reduction models, each housing should be drained and filled independently, even though
there may be a common level.
Initial oil change: The new oil in a speed reducer should be changed at the end of 250 hours of operation. This is equivalent
to 30 days of operation for 8 hours per day; 15 days of operation for 16 hours per day, or 10 days of operation for 24 hours per day.
Subsequent oil changes: Under normal conditions, after the initial oil change, the oil should be changed after every 2500
hours of operation, or every 6 months, whichever occurs first. Under severe conditions (rapid temperature changes, moist, dirty or corrosive environment) it may be necessary to change oil at intervals of one to three months. Periodic examination of oil samples taken
from the unit will help establish the appropriate interval.
Synthetic oils: Synthetic lubricants can be advantageous over mineral oils in that they generally are more stable, have a much
longer life, and operate over a wider temperature range. These oils are appropriate for any application but are especially useful when
units are subjected to low start-up temperatures or high operating temperatures. However, continuous operation above 225°F may cause
damage to seals or other components. It is recommended that the initial oil be changed or filtered after the first 1500 hours of operation
to remove metal particles that accumulate during break-in. Subsequent oil changes should be made after 5000 hours operation if units
are operating in a clean environment. This can be extended to 10,000 hours if using new reformulated Mobil SHC lubricants (orange in
color) and the lubricant remains free of contamination over this period. See comments under “Subsequent oil changes” for discussion
of severe ambient conditions.
Long term storage or infrequent operation: If a speed reducer is to stand idle for an extended period of time, either prior to
installation or during use, it is recommended that the unit be filled completely with oil to protect interior parts from rust and corrosion due
to internal condensation. Be sure to drain the oil to the proper level before placing the speed reducer in service.
Grease fittings: Some units are equipped with grease fittings to lubricate bearings not adequately lubricated by the oil splash.
These fittings must be lubricated every 3 - 6 months depending on operating conditions. bearing greases must be compatible with the
type of gear lubricant being used (i.e. mineral, synthetic, food grade, etc.). For mineral oils, use a high quality lithium base NLGOI #2
bearing grease. For synthetic oils, use a synthetic bearing grease such as Mobil Synthetic Universal grease, Mobilith SHC 100 or a suitable equivalent. For food grade lubricants, use Chevron FM grease, NGLI 2, or equivalent.
Low input speeds (under 1600 RPM): When input speeds are less than 1600 RPM, grease fittings will be required to lubricate any bearings not partially covered by the normal oil level.
Oil temperature: Speed reducers in normal operation can generate temperatures up to 200°F depending on the type of reducer and the severity of the application 9loading, duration of service, ambient temperatures). Excessive oil temperatures may be the result
of several factors including overloading, overfilling, underfilling or inadequate cooling.
