Important Safety Information

Most accidents that involve product operation, maintenance and repair are caused by failure to observe

basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous

situations before an accident occurs. A person must be alert to potential hazards. This person should also

have the necessary training, skills and tools to perform these functions properly.

Improper operation, lubrication, maintenance or repair of this product can be dangerous and

could result in injury or death.

Do not operate or perform any lubrication, maintenance or repair on this product, until you have

read and understood the operation, lubrication, maintenance and repair information.

Safety precautions and warnings are provided in this manual and on the product. If these hazard warnings

are not heeded, bodily injury or death could occur to you or to other persons.

The hazards are identified by the “Safety Alert Symbol” and followed by a “Signal Word” such as

“DANGER”, “WARNING” or “CAUTION”. The Safety Alert “WARNING” label is shown below.

The meaning of this safety alert symbol is as follows:

Attention! Become Alert! Your Safety is Involved.

The message that appears under the warning explains the hazard and can be either written or pictorially

presented.

A non-exhaustive list of operations that may cause product damage are identified by “NOTICE” labels

on the product and in this publication.

Caterpillar cannot anticipate every possible circumstance that might involve a potential hazard.

The warnings in this publication and on the product are, therefore, not all inclusive. You must

not use this product in any manner different from that considered by this manual without first

satisfying yourself that you have considered all safety rules and precautions applicable to the

operation of the product in the location of use, including site-specific rules and precautions

applicable to the worksite. If a tool, procedure, work method or operating technique that is not

specifically recommended by Caterpillar is used, you must satisfy yourself that it is safe for you

and for others. You should also ensure that the product will not be damaged or become unsafe by

the operation, lubrication, maintenance or repair procedures that you intend to use.

The information, specifications, and illustrations in this publication are on the basis of information that

was available at the time that the publication was written. The specifications, torques, pressures,

measurements, adjustments, illustrations, and other items can change at any time. These changes can

affect the service that is given to the product. Obtain the complete and most current information before you

start any job. Cat dealers have the most current information available.

When replacement parts are required for this

product Caterpillar recommends using Cat re-

placement parts or parts with equivalent speci-

fications including, but not limited to, physical

dimensions, type, strength and material.

Failure to heed this warning can lead to prema-

ture failures, product damage, personal injury or

death.

In the United States, the maintenance, replacement, or repair of the emission control devices and

systems may be performed by any repair establishment or individual of the owner's choosing.

Attachments, uneven ground conditions, soft ground

conditions, or poor ground conditions have effects on

rated loads. The operator is responsible for being

aware of these effects.

Machine stability is affected by many factors, in-

cluding the type of work tool and the position of a

work tool.

Machine stability and machine control can be sig-

nificantly affected if a work tool is not installed.

Operating a machine without a work tool can lead

to loss of control or tipping of the machine which

Dimension (A) represents the dump clearance. Dimension (B)

represents the reach.

When you operate a machine without a work tool,

avoid the following conditions:

The following tables provide the Rated Operating

operator. This section includes descriptions of

gauges, switches, machine controls, attachment

controls, transportation, and towing information.

Illustrations guide the operator through correct

procedures of checking, starting, operating, and

stopping the machine. Operating techniques that

are outlined in this publication are basic. Skill and

techniques develop as the operator gains knowledge

of the machine and the capabilities of the machine.

Note: Simple hydromechanical work tools may be

shipped without hydraulic oil. Uneven movement

may occur until all the air has been removed from the

work tool. You may need to add hydraulic oil to the

machine after the machine fills the circuits of the work

tool. Refer to Operation and Maintenance Manual,

“Hydraulic System Oil Level - Check” for the proper

procedure for checking the hydraulic oil level.

Note: If the machine is not equipped with a cab that

is enclosed, Caterpillar recommends the use of a

flying object guard. If the machine is equipped with

an enclosed cab, operate the machine with the cab

door in the CLOSED position.

4. If the blade cutting edge does not remain parallel

to the ground, the height of the blade needs to

be adjusted. Use the following steps in order to

adjust the height:

a. Lower the blade and the frame onto adjustable

stands.

b. Stop the engine and remove the ignition key.

c. Remove the bolts (6) for adjusting the height.

d. Move the frame to the desired height.

e. Ensure that the shims are installed. Install the

bolts for adjusting the height. Tighten the bolts

to a torque of 270 ± 40 N·m (199 ± 30 lb ft).

f. In order to test the adjustment, start the engine.

g. Repeat steps 2 and 3.

Tilt Lock

The angle blade has two modes of operation:

• Locked

• Spring load trip

In order to lock the blade, install the locking pin (4). In

the locked position, the blade can be used for heavy

operations. The blade will not tilt with the locking pin

in the locked position.

There may be lighter operations that allow the blade

to tilt. Remove the locking pin and store the locking

pin in the cab. This will help prevent damage to the

NOTICE

Stopping the engine immediately after it has been

working under load, can result in overheating and ac-

celerated wear of the engine components.

Refer to the following procedure, to allow the engine

to cool, and to prevent excessive temperatures in the

turbocharger housing (if equipped), which could cause

oil coking problems.

1. Operate the engine for five minutes at low idle

with no load.

Note: This allows hot areas in the engine to cool

gradually. This will extend the engine life.

2. Move the joysticks to the NEUTRAL position.

3. Turn the engine start switch key to the OFF

position.
