and

maintenance

The Bobcat skid-steer loader is highly maneuverable and
compact. It is rugged and useful under a wide variety of
conditions. This presents an operator with hazards
associated with off highway, rough terrain applications,
common with Bobcat loader usage.

An Operator’s Handbook is fastened to the operator
cab of the loader. Its brief instructions are convenient
to the operator. The Handbook is available from your
dealer in an English edition or one of many other
languages. See your Bobcat dealer for more
information on translated versions.

SI01-0903

The Bobcat loader has an internal combustion engine
with resultant heat and exhaust. All exhaust gasses can
kill or cause illness so use the loader with adequate
ventilation. The loader has a spark arrestor exhaust
system or muffler which is required for operation in
certain areas.
The dealer explains the capabilities and restrictions of the
Bobcat loader and attachments for each application. The
dealer demonstrates the safe operation according to
Bobcat instructional materials, which are also available to
operators. The dealer can also identify unsafe
modifications or use of unapproved attachments. The
attachments and buckets are designed for a Rated
Operating Capacity (some have restricted lift heights)
and secure fastening to the Bobcat loader. The user must
check with the dealer, or Bobcat literature, to determine
safe loads of materials of specified densities for the
loader-attachment combination.
The following publications and training materials provide
information on the safe use and maintenance of the
Bobcat loader and attachments:
•

The Delivery Report is used to assure that complete
instructions have been given to the new owner and
that the Bobcat loader and attachment is in safe
operating condition.

•

The Operation & Maintenance Manual delivered with
the Bobcat loader or attachment gives operating
information as well as routine maintenance and
service procedures. It is a part of the loader and can
be stored in a container provided inside the cab of the
loader. Replacement Operation & Maintenance
Manuals can be ordered from your Bobcat dealer.

•

Machine signs (decals) instruct on the safe operation
and care of your Bobcat loader or attachment. The
signs and their locations are shown in the Operation &
Maintenance Manual. Replacement signs are
available from your Bobcat dealer.

SAFETY INSTRUCTIONS (CONT’D)

•

Always clean the machine, disconnect the battery,
and disconnect the wiring from the Bobcat controllers
before welding. Cover rubber hoses, battery and all
other flammable parts. Keep a fire extinguisher near
the loader when welding. Have good ventilation when
grinding or welding painted parts. Wear dust mask
when grinding painted parts. Toxic dust or gas can be
produced.

•

Stop the engine and let it cool before adding fuel.
No smoking!

•

Use the procedure in the Operation & Maintenance
Manual for connecting the battery.

•

Use the procedure in the Operation & Maintenance
Manual for cleaning the spark arrestor muffler
(if equipped).

FIRE PREVENTION
The machines and some attachments have components
that are at high temperatures under normal operating
conditions. The primary source of high temperatures is
the engine and exhaust system. The electrical system, if
damaged or incorrectly maintained, can be a source of
arcs or sparks.
Flammable debris (leaves, straw, etc.) must be removed
regularly. If flammable debris is allowed to accumulate, it
can cause a fire hazard. Clean often to avoid this
accumulation. Flammable debris in the engine
compartment is a potential fire hazard.
The spark arrestor exhaust system (if equipped) is
designed to control the emission of hot particles from the
engine and exhaust system, but the muffler and the
exhaust gases are still hot.
•

Do not use the machine where exhaust, arcs, sparks
or hot components can contact flammable material,
explosive dust or gases.

•

The operator cab, engine compartment and engine
cooling system must be inspected every day and
cleaned if necessary to prevent fire hazards and
overheating.

•

Check all electrical wiring and connections for
damage. Keep the battery terminals clean and tight.
Repair or replace any damaged part.

•

Check fuel and hydraulic tubes, hoses and fittings for
damage and leakage. Never use open flame or bare
skin to check for leaks. Tighten or replace any parts
that show leakage. Always clean fluid spills. Do not
use gasoline or diesel fuel for cleaning parts. Use
commercial nonflammable solvents.

•

Figure 4

N-21901

•

Do not use ether or starting fluids on any engine which
has glow plugs. These starting aids can cause
explosion and injure you or bystanders.

Know where fire extinguishers and first aid kits are
located and how to use them. Fire extinguishers are
available from your Bobcat dealer. The fire
extinguisher can be installed in the location shown in
[Figure 4].

The system will retain the speed percentage as long as
the key remains ON (Standard Panel) or the STOP button
has not been pressed (Deluxe Panel).

The two speed allows you to reduce cycle times when
there is a long travel distance between the dig site and
the dump site. You can also use the two speed when
traveling from one job site to another at faster speeds.

EXAMPLE: You can be using the machine at 40%
and then disengage the Inching Control to
reposition the loader, then re-engage Inching
Control. The speed percentage will still be at 40%.

STOPPING THE BOBCAT LOADER

WARNING

Using The Steering Levers Or Joysticks
When the steering levers or joysticks are moved to the
neutral position, the hydrostatic transmission will act as a
service brake to stop the loader.

Before you leave the operator’s seat:
• Lower the lift arms, put the attachment flat on the
ground.
• Stop the engine.
• Engage the parking brake.
• Raise seat bar.
• (Foot Pedal Controls) Move pedals until both
lock.
• (Advanced Control System - ACS) Move the
hydraulic controls to the NEUTRAL POSITION to
make sure that both lift and tilt functions are
deactivated.
The seat bar system must deactivate the lift and tilt
control functions when the seat bar is up. Service the
system if hand controls do not deactivate.
• (Selectable Joystick Control - SJC) Move the
joysticks to the NEUTRAL POSITION to make
sure that travel and hydraulic functions are
deactivated.
The seat bar system must deactivate these functions
when the seat bar is up. Service the system if
controls do not deactivate.

IMPORTANT
When the temperature is below -30°C (-20°F),
hydrostatic oil must be warmed before starting. The
hydrostatic system will not get enough oil at low
temperatures and will be damaged. Park the machine
in an area where the temperature will be above 18°C
(0°F) if possible.

ATTACHMENTS AND BUCKETS
Choosing The Correct Bucket
NOTE: Warranty is void if non-approved attachments
are used on the Bobcat loader.

WARNING
Never use attachments or buckets which are not
approved by Bobcat Company. Buckets and
attachments for safe loads of specified densities are
approved for each model. Unapproved attachments
can cause injury or death.

B-16251

W-2052-0500

Exceeding the Rated Operating Capacity [Figure OI-61]
can cause the following problems:

The dealer can identify, for each model loader, the
attachments and buckets approved by Bobcat. The buckets
and attachments are approved for Rated Operating
Capacity and for secure fastening to the Bob-Tach.

•
•
•
•

Steering the loader may be difficult.
Tires will wear faster.
There will be a loss of stability.
The life of the Bobcat loader will be reduced.

The Rated Operating Capacity for this loader is shown on
a decal in the operator cab. (See Fluid Capacities on
Page SA-6).
The Rated Operating Capacity is determined by using a
standard dirt bucket, and material of normal density, such
as dirt or dry gravel. If longer buckets are used, the load
center moves forward and reduces the Rated Operating
Capacity. If very dense material is loaded, the volume
must be reduced to prevent overloading.

ATTACHMENTS AND BUCKETS (CONT’D)

Figure OI-63

Choosing The Correct Bucket (Cont’d)

Use the correct bucket size for the type and density of
material being handled. For safe handling of materials
and avoiding machine damage, the attachment
(or bucket) should handle a full load without going over
the Rated Operating Capacity for the loader. Partial loads
make steering more difficult.
Pallet Forks
Figure OI-62
P-31238

Pull the Bob-Tach levers all the way up (Item 1)
[Figure OI-63].
Load varies with
model of pallet fork
being used.

Enter the loader and perform the PRE-STARTING
PROCEDURE (See PRE-STARTING PROCEDURES on
Page OI-25).
Lower the lift arms and tilt the Bob-Tach forward.
Drive the loader forward until the top edge of the
Bob-Tach is completely under the top flange of the bucket
[Figure OI-63] (or other attachment). Be sure the
Bob-Tach levers do not hit the bucket.

B-17255

If a pallet fork attachment is used, the load center moves
forward and reduces the Rated Operating Capacity.

Figure OI-64

The maximum load to be carried when using a pallet fork
is shown on a decal located on the pallet fork
frame (Item 1) [Figure OI-62].

WARNING
AVOID INJURY OR DEATH
Do not exceed Rated Operating Capacity (ROC).
Excessive load can cause tipping or loss of control.

Operation & Maintenance Manual

SEAT BAR RESTRAINT SYSTEM
The seat bar restraint system has a pivoting seat bar with
arm rests.
The operator controls the use of the seat bar. The seat
bar in the down position helps to keep the operator in the
seat.
Models with foot pedals have hydraulic valve spool
interlocks for the lift and tilt functions. The spool
interlocks require the operator to lower the seat bar in
order to operate the foot pedal controls.
When the seat bar is down, the PRESS TO OPERATE
LOADER Button is activated and the engine is running,
the lift, tilt and traction drive functions can be operated.

Lower the seat bar, press the PRESS TO OPERATE
LOADER Button, lower the lift arms. Operate the lift
control. While the lift arms are going up, raise the seat
bar. The lift arms must stop.
Lower the seat bar, press the PRESS TO OPERATE
LOADER Button, lower the lift arms and put the
attachment flat on the ground. Stop the engine. Raise the
seat bar. Operate the foot pedals and handles (if
equipped) to be sure they are firmly locked in the
NEUTRAL position (except joysticks).

TIRE MAINTENANCE

Rear tires usually wear faster than front tires. To keep tire
wear even, move the front tires to the rear and rear tires
to the front [Figure PM-53].

Wheel Nuts
Figure PM-52

It is important to keep the same size tires on each side of
the loader. If different sizes are used, each tire will be
turning at a different rate and cause excessive wear. The
tread bars of all the tires must face the same direction.
Recommended tire pressure must be maintained to avoid
excessive tire wear and loss of stability and handling
capability. Check for correct pressure before operating
the loader.
Mounting
Tires are to be repaired only by an authorized person
using the proper procedures and safe equipment.
Tires and rims must always be checked for correct size
before mounting. Check rim and tire bead for damage.

P-31225

For the service interval to check the wheel nuts (See
SERVICE SCHEDULE on Page PM-5). The correct
torque is 142-156 Nm torque [Figure PM-52].
Rotating

The rim flange must be cleaned and free of rust.
The tire bead and rim flange must be lubricated with a
rubber lubricant before mounting the tire.
Avoid excessive pressure which can rupture the tire and
cause serious injury or death.

Check the tires regularly for wear, damage and pressure.

During inflation of the tire, check the tire pressure
frequently to avoid over inflation.

IMPORTANT
Inflate tires to the MAXIMUM pressure shown on the
sidewall of the tire. DO NOT mix brands of tires used
on the same loader.
