SAFETY INSTRUCTIONS

Safe Operation Is The Operator’s Responsibility

Carefully follow the operating and maintenance

instructions in this manual.

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.

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.

• 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.

WARNING

Operator must have instructions before operating the

machine. Untrained operators can cause injury or

death.

W-2001-0502

IMPORTANT

This notice identifies procedures which must be

followed to avoid damage to the machine.

I-2019-0284

WARNING

Warnings on the machine and in the manuals are for

your safety. Failure to obey warnings can cause

injury or death.

W-2044-1285

The Bobcat loader and attachment must be in good

operating condition before use.

Check all of the items on the Bobcat Service Schedule

Decal under the 8-10 hour column or as shown in the

Operation & Maintenance Manual.

SAFE OPERATION NEEDS A QUALIFIED OPERATOR

For an operator to be qualified, he must not use drugs or

alcoholic drinks which impair his alertness or

coordination while working. An operator who is taking

prescription drugs must get medical advice to determine

if he can safely operate a machine.

A qualified operator must do the following:

Understand the Written Instructions, Rules and

Regulations

• The written instructions from Bobcat company include

the Delivery Report, Operation & Maintenance

Manual, Operator’s Handbook and machine signs

(decals).

• Check the rules and regulations at your location. The

rules may include an employer’s work safety

requirements. Regulations may apply to local driving

requirements or use of a Slow Moving Vehicle (SMV)

emblem. Regulations may identify a hazard such as a

utility line.

Have Training with Actual Operation

• Operator training must consist of a demonstration and

verbal instruction. This training is given by your

Bobcat dealer before the product is delivered.

• The new operator must start in an area without

bystanders and use all the controls until he can

operate the machine and attachment safely under all

conditions of the work area. Always fasten seat belt

before operating.

Know the Work Conditions

• Know the weight of the materials being handled.

Avoid exceeding the Rated Operating Capacity of the

machine. Material which is very dense will be heavier

than the same volume of less dense material. Reduce

the size of load if handling dense material.

• The operator must know any prohibited uses or work

areas, for example, he needs to know about

excessive slopes.

• Know the location of any underground lines.

• Wear tight fitting clothing. Always wear safety glasses

when doing maintenance or service. Safety glasses,

hearing protection or special applications kit are

required for some work. See your dealer about

Bobcat Safety equipment.

XV Operation & Maintenance Manual

SAFETY INSTRUCTIONS (CONT’D)

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.

• 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.

• 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).

Figure 4

• 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].

SEAT BAR RESTRAINT SYSTEM

Operation

Figure OI-22

The seat bar restraint system has a pivoting seat bar with

arm rests (Item 1) [Figure OI-22].

The operator controls the use of the seat bar. The seat

bar is the down position helps to keep the operator in the

seat.

WARNING

AVOID INJURY OR DEATH

When operating the machine:

• Keep the seat belt fastened snugly.

• The seat bar must be lowered.

• Keep your feet on the pedal controls or footrests

and hands on steering levers.

W-2261-0799

When the seat bar is down, the PRESS TO OPERATE

LOADER button is activated, and the brake is released,

the lift, tilt, and traction drive functions can be operated.

(Traction drive will operate only when the engine is

running.)

When the seat bar is up, the lift, tilt and traction drive

functions are deactivated and both foot pedals

(if equipped) will be locked.

WARNING

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.

W-2052-0500

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.

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.

Figure OI-61

Exceeding the Rated Operating Capacity [Figure OI-61]

can cause the following problems:

• 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.

S250 Bobcat Loader

OI-34 Operation & Maintenance Manual

ATTACHMENTS AND BUCKETS (CONT’D)

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

If a pallet fork attachment is used, the load center moves

forward and reduces the Rated Operating Capacity.

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.

W-2053-0903

See your Bobcat Dealer for more information about pallet

fork inspection, maintenance and replacement. See your

Bobcat loader dealer for Rated Operating Capacity when

using a pallet fork and for other available attachments.

TOWING THE LOADER

Towing Procedure

Because of the design of the loader, there is not a

recommended towing procedure.

• The loader can be lifted onto a transport vehicle.

• The loader can be skidded a short distance to move

for service (EXAMPLE: Move onto a transport

vehicle.) without damage to the hydrostatic system.

(The tires/tracks will not turn.) There might be slight

wear to the tires/tracks when the loader is skidded.

The towing chain (or cable) must be rated at 1 & 1/2

times the weight of the loader (See Machine Rating

on Page SPEC-4).

SEAT BELT

Inspection and Maintenance

WARNING

Failure to properly inspect and maintain seat belt can

cause serious injury or death in the event of an

accident.

The entire seat belt system must be replaced if the

machine has been involved in an accident or if any

part has been damaged.

W-2466-0703

Check the seat belt daily for correct function.

Inspect the seat belt system thoroughly at least once

each year or more often if the machine is exposed to

severe environmental conditions or applications.

Any seat belt system that shows cuts, fraying, extreme or

unusual wear, significant discolorations due to ultraviolet

(UV) exposure, dusty / dirty conditions, abrasion to the

seat belt webbing, or damage to the buckle, latch plate,

retractor (if equipped), hardware or any other obvious

problem should be replaced immediately.

1. Check the webbing. If the system is equipped with a

retractor, pull the webbing completely our and inspect

the full length of the webbing. Look for cuts, wear,

fraying, dirt and stiffness.

2. Check the buckle and latch for correct operation.

Make sure latch plate is not excessively worn,

deformed or buckle is not damaged or casing broken.

3. Check the retractor web storage device (if equipped)

by extending webbing to determine if it looks correct

and that it spools out and retracts webbing correctly.

4. Check webbing in areas exposed to ultraviolet (UV)

rays from the sun or extreme dust or dirt. If the original

color of the webbing in these areas is extremely faded

PM-12 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.

When the seat bar is up, the lift and tilt control pedals are

locked when returned to the NEUTRAL position.

Models with the Advanced Control System (ACS)

have mechanical interlocks for the handles and pedals.

The interlocks for the handles and pedals require the

operator to lower the seat bar in order to operate the

selected 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

using the selected controls (handles, or foot pedals).

When the seat bar is up, the handles and pedals are

locked when returned to the NEUTRAL position.

Models with Selectable Joystick Control (SJC) have

electrical deactivation of joystick functions. Activation of

functions require the operator to lower the seat bar.

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.

When the seat bar is up, the joystick functions are

deactivated even though the joystick does not

mechanically lock.

Inspecting The Seat Bar

Sit in the seat and fasten the seat belt. Engage the

parking brake. Pull the seat bar all the way down. Start

the engine. Press the PRESS TO OPERATE LOADER

Button.

Operate the hydraulic controls to check that both the lift

and tilt functions operate correctly. Raise the lift arms

until the attachment is about 600 mm off the ground.

Raise the seat bar. Move the hydraulic controls. Pedals

and handles (if equipped) must be firmly locked in the

NEUTRAL position (except joysticks). There must be no

motion of the lift arms or tilt (attachment) when the

controls are moved.

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).

Maintaining The Seat Bar

(See SERVICE SCHEDULE on Page PM-5) and on the

loader for correct service interval.

Figure PM-15

Use compressed air to clean any debris or dirt from the

pivot parts (Item 1) [Figure PM-15]. Do not lubricate.

Inspect all mounting hardware. The correct bolt torque is

35 Nm.

If the seat bar system does not function correctly, replace

parts that are worn or damaged. Use only genuine

Bobcat replacement parts.

WARNING

The seat bar system must deactivate the lift and tilt

control functions when the seat bar is up. Service the

system if hydraulic controls do not deactivate.

TIRE MAINTENANCE

Wheel Nuts

Figure PM-52

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

Check the tires regularly for wear, damage and pressure.

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.

I-2057-0794

Figure PM-53

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].

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.

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.

During inflation of the tire, check the tire pressure

frequently to avoid over inflation.
