WARNING

WARNING

1

General Safety Precautions

A. Avoid Carbon Monoxide Poisoning

All engine exhaust contains

carbon monoxide, a deadly gas.

Breathing carbon monoxide can

cause headaches, dizziness,

drowsiness, nausea, confusion

and eventually death.

to store and dispense fuel. TecumsehPower

recommends purchasing gasoline in containers with

a capacity of 2.5 gallons or less. Small containers

are easier to handle and help eliminate spillage

during refueling.

• DO NOT pour fuel from engine or siphon fuel by

mouth.

C. Adult Supervision of Operation, Refueling

and Maintenance

Not everyone who is allowed to use an engine is capable

of safely and responsibly operating, maintaining and/or

fueling it. TecumsehPower recommends the following:

• An adult should fuel the engine. NEVER allow

children to refuel an engine.

• An adult should perform maintenance on an engine.

Only allow children to perform maintenance if an

adult has determined they are experienced and

capable of such operation.

• An adult should start the engine. Only allow children

to start the engine if an adult has determined they

are experienced and capable of such operation.

To avoid unsupervised operation of the engine, especially

by children, NEVER leave it unattended when it is

running.

D. Stay Away from Rotating Parts

NEVER operate an engine with an unguarded engine

shaft.

The equipment manufacturer may attach a sprocket and

chain or pulley and belt to the engine

shaft. If these parts are not properly

guarded, or if you are not sure whether

they are properly guarded, DO NOT

use your engine; contact the equipment

manufacturer. Hands, feet, hair, jewelry,

clothing, etc. can become entangled in

rotating parts, leading to serious injury or

death. To avoid serious injury or death,

be sure the flywheel guard is in place.

Carbon monoxide is a colorless, odorless, tasteless gas

which may be present even if you do not see or smell

any engine exhaust. Deadly levels of carbon monoxide

can collect rapidly and you can quickly be overcome and

unable to save yourself. Also, deadly levels of carbon

monoxide can linger for hours or days in enclosed or

poorly-ventilated areas. If you experience any symptoms

of carbon monoxide poisoning, leave the area immediately,

get fresh air, and SEEK MEDICAL TREATMENT.

To prevent serious injury or death from carbon

monoxide:

• NEVER run engine indoors. Even if you try to

ventilate engine exhaust with fans or open windows

and doors, carbon monoxide can rapidly reach

dangerous levels.

• NEVER run engine in poorly-ventilated or

partially enclosed areas such as barns, garages,

basements, carports, under dwellings, or in pits.

• NEVER run engine outdoors where engine exhaust

can be drawn into a building through openings

such as windows and doors.

B. Avoid Gasoline Fires

Gasoline (fuel) vapors are highly flammable

and can explode. Fuel vapors can spread

and be ignited by a spark or flame many feet

away from engine. To prevent injury or death

from fuel fires, follow these instructions:

• NEVER store engine with fuel in fuel

tank inside a building with potential

sources of ignition such as hot water

and space heaters, clothes dryers, electric motors,

etc.

• NEVER remove fuel cap or add fuel when engine

is running.

• NEVER start or operate the engine with fuel fill cap

removed.

• Allow engine to cool before refueling.

• NEVER fill fuel tank indoors. Fill fuel tank outdoors

in a well-ventilated area.

• DO NOT smoke while refueling tank.

• Use only an approved red GASOLINE container

Fuel Recommendations

Today’s fuels have a short shelf life and it is recommended you buy no more than a two week

supply at a time.

GASOLINE

TecumsehPower strongly recommends the use of fresh, clean, unleaded regular gasoline in all

TecumsehPower engines. Unleaded gasoline burns cleaner, extends engine life, and promotes good

starting by reducing the build-up of combustion chamber deposits. Leaded gasoline, gasohol containing

no more than 10% ethanol, premium gasoline, or unleaded gasoline containing no more than 15% MTBE

(Methyl Tertiary Butyl Ether), 15% ETBE (Ethyl Tertiary Butyl Ether) or 10% ethanol, can be used if

unleaded regular gasoline is not available.

Reformulated gasoline that is now required in several areas of the United States is also acceptable.

NEVER USE gasoline, fuel conditioners, additives or stabilizers containing methanol, gasohol containing

more than 10% ethanol, unleaded regular gasoline containing more than 15% MTBE (Methyl Tertiary Butyl

Ether), 15% ETBE (Ethyl Tertiary Butyl Ether) or 10% ethanol, gasoline additives, or white gas because

engine/fuel system damage could result.

SPECIALTY FUELS

Fuels being marketed for use on small engines can have a significant effect on starting and engine

performance. Prior to using any specialty fuel, the Reid Vapor Pressure (RVP) must be determined. Fuels

with a rating of less than 50kPa (7psi) should not be used in summer, and fuel with a rating of 85kPa

(12psi) should not be used during winter.

SHORT TERM STORAGE

NEVER store the engine with fuel in the fuel tank inside a building with potential sources

of ignition such as hot water and space heaters, clothes dryers, electric motors, etc.

If engine fuel stored in the gas tank and/or an approved gas container is to be unused without gasoline

stabilizer for more than 15-30 days, prepare it for short term/seasonal storage.

TecumsehPower recommends using ULTRA-FRESH™ or Fuel Saver Plus Gasoline Stabilizer plus Fuel

System Cleaner as an acceptable method of minimizing formation of fuel gum deposits during storage.

This product is available from your Authorized TecumsehPower Servicing Dealer.

Always follow mix ratio found on stabilizer container. Failure to do so may result in equipment damage.

It is not necessary to drain stabilized gas from carburetor.

FUEL TREATMENT

1. Add fuel stabilizer according to manufacturer’s instructions.

2. Run engine at least 10 minutes after adding stabilizer to allow it to reach carburetor.

3. Instead of using a fuel preservative/stabilizer, you can empty the fuel tank as described under "Extended

Storage”.

WARNING

8

Fuel Recommendations - continued

EXTENDED STORAGE

NOTES

Clean debris from engine before draining fuel from carburetor. If you have prepared your fuel for short

term storage it is not necessary to drain fuel that contains stabilizer from your carburetor.

To avoid severe injury or death, DO NOT pour fuel from engine or siphon fuel by mouth.

1. To prevent serious injury from fuel fires, empty fuel tank by running engine until it stops from lack of

fuel. DO NOT attempt to pour fuel from engine.

2. Run the engine while waiting until the remaining fuel is consumed.

NEVER leave the engine unattended when it is running and NEVER run engine in enclosed areas.

FUEL ADDITIVES

Only fuel additives such as TecumsehPower’s fuel stabilizer Part No. 730245A or liquid varieties can be

used when mixed properly. For winter applications, Isopropyl alcohol fuel dryers may be used in the fuel

system but must be mixed at the proper ratio recommended by the manufacturer. NEVER USE METHANOL

BASED FUEL DRYERS.

Four Cycle Troubleshooting

The following is provided as a basic troubleshooting guide. Its use requires a complete review of all conditions

and symptoms. Always examine the exterior for clues: leaks, excessive dirt, or obvious damage. Some repairs will

require the assistance of a TecumsehPower Servicing Dealer.

Should more extensive repair be needed, we recommend you contact a local TecumsehPower Servicing Dealer

for repair. Repair manuals are also available from your local dealer or direct from www.TecumsehPower.com. A

complete list of the available manuals can be found at the end of this book.

NOTE: Refer to Technician's Handbook for a more detailed list of remedies.

Preparation

Before troubleshooting any system problem, see original equipment manufacturer’s (O.E.M.) instructions.

Make your troubleshooting easier by preparing as follows:

• Work in a clean, well-lighted place.

• Keep proper tools and materials nearby.

• Keep an adequate supply of clean petroleum-based solvent.

To reduce the risk of serious injury or death from fires and/or explosions, NEVER use flammable

solvents (e.g., gasoline) to clean serviceable parts. Use a water-based, non-flammable solvent

such as TecumsehPower Degreaser Cleaner.

NEVER use compressed air to clean debris from yourself or your clothing. When using compressed

air to clean or dry serviceable parts:

• Wear appropriate eye protection.

• Use only approved air blow nozzles.

solvents (e.g., gasoline) to clean serviceable parts. Use a water-based, non-flammable solvent

such as TecumsehPower Degreaser Cleaner.

NEVER use compressed air to clean debris from yourself or your clothing. When using compressed

air to clean or dry serviceable parts:

• Wear appropriate eye protection.

• Use only approved air blow nozzles.

• Air pressure must not exceed 30psi (206kPa).

• Shield yourself and bystanders from flying debris.

CAUTION

Should more extensive repair be needed, we recommend you contact a local TecumsehPower Servicing Dealer

for repair. Repair manuals are also available from your local dealer or direct from www.TecumsehPower.com. A

Basic Gear Drive Troubleshooting

Preparation

NOTE

Before troubleshooting any system problem, see original equipment manufacturer’s (O.E.M.) instructions.

Make your troubleshooting easier by preparing as follows:

• Work in a clean, well-lighted place.

• Keep proper tools and materials nearby.

• Keep an adequate supply of clean petroleum-based solvent.

To avoid carbon monoxide poisoning, make sure engine is outdoors in a well-ventilated area.

Some maintenance procedures cannot be performed until the vehicle wheels are secured and off

the ground. Failure to do so could result in death or serious injury to yourself and/or bystanders.

DO NOT attempt any maintenance procedures with the engine running. Doing so could result in

death or serious injury to yourself and/or bystanders.

Use care when performing inspection of the drive belt assembly including all vehicle linkage. Failure

to do so could result in death or serious injury to yourself and/or bystanders.

For proper declutching to occur, it is very important that

the engine belt guide be set at a predetermined clearance

when engaged (set by the manufacturer) and away from

the belt with the belt engaged.

With clutch disengaged, it is very important that the belt

blossoms away from the engine pulley. Belt must stop

turning before transaxle shifting can occur.

1/16" to 3/16"

(1.6 mm - 4.8 mm) THIS DIMENSION

VARIES FROM EACH

MANUFACTURER

Improper belt or belt guide clearance will not allow the belt to disengage, causing internal transmission

damage.

Hard Shifting Transaxles and Drive Belts

Often hard shifting is blamed on an internal problem in the transaxle.

To determine if the problem is transaxle or equipment related make these simple checks.

1. Turn the unit off so that all power is removed to the transaxle.

2. With the unit off, move the shift lever through the shift gate. Movement of the lever should have only slight

resistance. The shifting effort should be equal when the engine is off and when running. If the unit is difficult to

shift the problem would be internal and the transaxle would need to be removed and repaired.

3. If the unit shifts with ease, check the following areas that would be equipment related. Check to see if the belt

is releasing from the pulley on the engine and transmission / transaxle, it may require that the belt guides be

repositioned. The distance required from the pulley to the guide is typically 1/16" to 3/16" (1.6 mm - 4.8 mm),

always check the O.E.M. specs.

4. Check to see if the pulley is damaged and may not be releasing the belt.

5. Confirm the correct length and type of belt, as recommended by the manufacturer, is installed.

WARNING

WARNING

WARNING

20

6. Check the brake/clutch pedal to make sure that when the pedal is depressed that the idler pulley is releasing

the belt tension before it applies the brake. If this does not happen the unit will still be under a load and be

impossible to shift.

7. The final area to check would be for damaged or binding shift linkage.

Hard shifting with the engine off could be caused by:

1. Shift linkage out of adjustment.

2. Corrosion in the transaxle or transmission.

3. Damaged shift keys, gears, or shifter brake shaft.

4. Belt guides missing or improperly adjusted (see equipment manufacturer specs).

Unit seems to slip:

1. Check for proper belt adjustment (consult O.E.M. operator's manual).

2. Check for proper clutch/brake adjustment (consult O.E.M. operator's manual).

3. Check pulley condition and wheels for sheared or damaged keys.

4. Check drive belt condition, if glazed or worn, replace it.

5. Possible internal transmission damage. We suggest you contact a local TecumsehPower Servicing Dealer.

1800 / VST Troubleshooting

The information on this page has been provided to help

understand the internal operation of the VST. Do not

use this information to attempt any internal repairs.

TecumsehPower's current policy on hydrostatic

transaxles that have internal failures is to replace

the complete unit. This has not changed. However,

TecumsehPower would like to provide a failure

checklist to assist in making an accurate evaluation

of the complete tractor to eliminate any unnecessary

replacements. Here is a list of items to check and

corrective actions to take.

To properly test the unit for power loss.

1. Allow the unit to cool before trying the following

steps.

2. Put the shift lever in a position that is 1/2 of the

travel distance from neutral to forward.

3. Place the tractor on a 17o grade.

4. Drive the tractor up the grade (without the mower

deck engaged). The loss of power experienced

should be approximately 20%. This is considered

normal. If the loss of power is approximately 50%,

this would be considered excessive.

5. Bring the unit to neutral, shift into forward and note

the response. Care should be taken to move the

lever slowly to avoid an abrupt wheel lift.

To determine if the problem is with the hydro unit, all

external problem possibilities must be eliminated. Here

are some potential problem areas.

1. Overheating: Heat can cause a breakdown in the

viscosity of the oil which reduces the pressure used

to move the motor. Remove any grass, debris, or

dirt buildup on the transaxle cover and / or between

the cooling fins and fan. Buildup of material will

reduce the cooling efficiency.

2. Belt slippage: A belt that is worn, stretched, or

the wrong belt (too large or wide) can cause belt

slippage. This condition may have the same loss of

power symptom as overheating. Typically, the unit

which has a slipping belt will exhibit a pulsating type

motion of the mower. This can be verified visually

by watching the belt and pulley relationship. If the

belt is slipping, the belt will chatter or jump on the

pulley. If the belt is good, a smooth rotation will be

seen. Replace the belt and inspect the pulley for

damage.

3. Leakage: The VST and 1800 Series have two oil

reservoirs which can be checked for diagnostic

purposes. The first is the pump and motor expansion

bellows. With a small diameter blunt or round nose

probe, check the bellows depth through the center

vent hole. Proper depth from the edge of that hole

is 3-1/4 - 3-1/2 inches (8.25 - 8.9 cm).

The second chamber is for the output gears

including the differential. FIRST make sure the

tractor is level, then remove the drain/fill plug.

NOTE: Some units that do not have differential

disconnect will have two plugs. We recommend

using only the primary plug. With a small pocket

rule insert until you touch bottom of case. You

can then remove it and check for 1/4 - 3/8 inches

(6.5 - 9.5 mm) contact, this is full at its 8 oz.

capacity.

4. Low ground speed: If the linkage is not

synchronized to absolute neutral, or the shift lever

is not properly fastened to the tapered control shaft,

full forward travel may not be achieved. This may

cause a false reading and be misdiagnosed as a

low power condition. This also could be caused by

the brake not releasing.

To determine absolute neutral, the hole in the

tapered control shaft must face straight up and

down, at this point make sure the O.E.M. linkage is

in neutral. To properly fasten the control lever to the

shaft, torque the nut to 25-35 ft. lbs. (34 - 48.3 Nm)

of torque with the shaft and the lever in neutral.

When attaching the shifter arm to the shaft you

must prevent any rotation during torquing. This can

be done by placing a long 5/16" bolt in the hole of

the shaft. Hold the bolt until the tapers are locked

and the nut torque is correct.

To make sure that the brake is not binding, drive the

unit up a slight grade. Position the speed control

lever into neutral. The unit should coast backwards.

If the unit does not coast back slowly, the brake is

not released from the brake disk. Adjust the brake

linkage to release the brake completely when the

foot pedal is released.

5. Hard to shift: Typically hard to shift symptoms are

not caused by the hydrostatic unit. The shift arm

should move with relative ease. Approximately 40-

50 in. lbs. (4.48 - 5.6 Nm) at the transaxle for foot

pedal units or 150-200 in. lbs. (16.8 -22.4 Nm) for

hand operated units. This varies depending on the

type of linkage. Binding may occur in the linkage

connections due to rust or moisture. Lubricating

these connections and checking for bent or

damaged parts should resolve hard shifting.
