Operation & Maintenance Manual

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 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
loader and attachments:

•

The Delivery Report is used to assure that complete
instructions have been given to the new owner and
that the machine 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.

SAFETY INSTRUCTIONS (CONT’D)

Safe Operation Is The Operator’s Responsibility 
(Cont’d)

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
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.

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
[Figure 4].
