The serviceman or mechanic may be unfamiliar with 

many of the systems on this machine.  This makes it   

important to use caution when performing service work. 

A knowledge of the system and or components is im-

portant before the removal or disassembly of any com-

ponent.

Because of the size of some of the machine compo-

nents, the serviceman or mechanic should check the 

weights noted in this manual. Use proper lifting proce-

dures when removing any components. Weight of com-

ponents table is shown in the section ;  

SPECIFICATIONS.

The following is a list of basic precautions that must al-

ways be observed.

(1) Read and understand all Warning plates and decal 

on the machine before Operating, Maintaining or 

Repairing this machine.

(2) Always wear protective glasses and protective 

shoes when working around machines.  In particu-

lar, wear protective glasses when using hammers, 

punches or drifts on any part of the machine or at-

tachments. Use welders gloves, hood/goggles, 

apron and the protective clothing appropriate to the 

welding job being performed.  Do not wear loose fit-

ting or torn clothing. Remove all rings from fingers, 

loose jewelry, confine long hair and loose clothing 

before working on this machinery.

(3) Disconnect the battery and hang a "Do Not Oper-

ate" tag in the Operators Compartment. Remove ig-

nition keys.

(4) If possible, make all repairs with the machine 

parked on a firm level surface. Block the machine 

so it does not roll while working on or under the ma-

chine. Hang a "Do Not Operate" tag in the Opera-

tors Compartment.

(5) Do not work on any machine that is supported only 

by lift, jacks or a hoist.  Always use blocks or jack 

stands, capable of supporting the machine, before 

performing any disassembly.

(6) Relieve all pressure in air, oil or water systems be-

fore any lines, fittings or related items are discon-

nected or removed.  Always make sure all raised 

components are blocked correctly and be alert for 

possible pressure when disconnecting any device 

from a system that utilizes pressure.

(7) Lower the bucket, dozer, or other attachments to 

the ground before performing any work on the ma-

chine. If this cannot be done, make sure the bucket, 

dozer, ripper or other attachment is blocked correct-

ly to prevent it from dropping unexpectedly.

(8) Use steps and grab handles when mounting or dis-

mounting a machine.  Clean any mud or debris from 

steps, walkways or work platforms before using.  

Always face to the machine when using steps, lad-

ders and walkways.  When it is not possible to use 

the designed access system, provide ladders, scaf-

folds, or work platforms to perform safe repair oper-

ations.

(9) To avoid back injury, use a hoist when lifting com-

ponents which weigh 20kg (45lbs) or more. Make 

sure all chains, hooks, slings, etc., are in good con-

dition and are the correct capacity.  Be sure hooks 

are positioned correctly.  Lifting eyes are not to be 

side loaded during a lifting operation.

(10)To avoid burns, be alert for hot parts on machines 

which have just been stopped and hot fluids in 

lines, tubes and compartments.

(11)Be careful when removing cover plates. Gradually 

back off the last two capscrews or nuts located at 

opposite ends of the cover or device and carefully 

pry cover loose to relieve any spring or other pres-

sure, before removing the last two capscrews or 

nuts completely.

(12)Be careful when removing filler caps, breathers and 

plugs on the machine.  Hold a rag over the cap or 

plug to prevent being sprayed or splashed by liq-

uids under pressure.  The danger is even greater if 

the machine has just been stopped because fluids 

can be hot.
