AVOID ACCIDENTS
Most accidents, whether they occur in industry, on the farm, at home or on
the highway, are caused by the failure of some individuals to follow simple
and fundamental safety rules or precautions. For this reason MOST
ACCIDENTS CAN BE PREVENTED by recognising the real cause and
doing something about it before the accident occurs.
Regardless of the care used in the design and construction of any type of
equipment there are conditions that cannot be completely safeguarded
against without interfering with reasonable accessibility and efficient
operation.
Carefully read indications, cautions and safety warning quoted in the
“SAFETY RULES” section.
A careful operator is the best insurance against an accident.
The complete observance of one simple rule would prevent many thousand
serious injuries each year.
That rule is:
Never attempt to clean, oil or adjust a machine while it is in motion.
ATTENTION
On machines having hydraulically, mechanically and/or cable
controlled equipment (such as showels, loaders, dozers, scrapers
etc.) be certain the equipment is lowered to the ground before servicing,
adjusting and/or repairing.
If it is necessary to have the equipment partially or fully raised to gain
access to certain items, be sure the equipment is suitably supported
by means other than the hydraulic lift cylinders, cable and/or mechanical
device used for controlling the equipment.

SAFETY PRECAUTIONS
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 important before the removal or disassembly of any
component.
Because of the size of some of the machine
components, the serviceman or mechanic should
check the weights noted in this manual. Use proper
lifting procedures when removing any components.
Weight of components table is shown in the section;
SPECIFICATIONS.
The following is a list of basic precautions that must
always 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
particular, wear protective glasses when using
hammers, punches or drifts on any part of the
machine or attachments. Use welders gloves,
hood/goggles, apron and the protective clothing
appropriate to the welding job being performed.
Do not wear loose fitting 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
Operate” tag in the Operators Compartment.
Remove ignition keys.
4. If possible, make all repairs with the machine
parked on a level, hard surface. Block the machine
so it does not roll while working on or under the
WARNING
The proper and safe lubrication and maintenance for
this machine, recommended by Distributor, are
outlined in the OPERATOR’S MANUAL for the
machine.
Improper performance of lubrication or maintenance
procedures are dangerous and could result in injury
or death. Read and understand the MANUAL before
performing any lubrication or maintenance.
machine. Hang a “Do Not Operate” tag in the
Operators 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.
WARNING
Do not operate this machine unless you have read
and understand the instructions in the OPERATOR’S
MANUAL. Improper machine operation is dangerous
and could result in injury or death.
6. Relieve all pressure in air, oil or water systems
before any lines, fittings or related items are
disconnected 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
machine. If this cannot be done, make sure the
bucket, dozer, ripper or other attachment is
blocked correctly to prevent it from dropping
unexpectedly.
8. Use steps and grab handles when mounting or
dismounting a machine. Clean any mud or debris
from steps, walkways or work platforms before
using. Always face to the machine when using
steps, ladders and walkways. When it is not
possible to use the designed access system,
provide ladders, scaffolds, or work platforms to
perform safe repair operations.
9. To avoid back injury, use a hoist when lifting
components which weigh 20 kg (45 lbs) or more.
Make sure all chains, hooks, slings, etc., are in
good condition 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
pressure, 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 liquids under pressure. The danger is even
greater if the machine has just been stopped
because fluids can be hot.
13. Always use the proper tools that are in good
condition and that are suited for the job at hand.
Be sure you understand how to use them before
performing any service work.
14. Reinstall all fasteners with the same part number.
Do not use a lesser quality fastener if
replacements are necessary.
15. Repairs which require welding should be
performed only with the benefit of the appropriate
reference information and by personnel
adequately trained and knowledgeable in welding
procedures. Determine type of metal being
welded and select correct welding procedure
and electrodes, rods or wire to provide a weld
metal strength equivalent at least to that of the
parent metal. Make sure to disconnect battery
before any welding procedures are attempted.
16. Do not damage wiring during removal operations.
Reinstall the wiring so it is not damaged nor will
be damaged in operation of the machine by
contacting sharp corners, or by rubbing against
some object or hot surface. Do not connect
wiring to a line containing fluid.
17. Be sure all protective devices including guards
and shields are properly installed and functioning
correctly before starting a repair. If a guard or
shield must be removed to perform the repair
work, use extra caution and replace the guard or
shield after repair is completed.
18. The maintenance and repair work while holding
the bucket raised is dangerous due to the
possibility of a falling attachment. Don’t fail to
lower the attachment and place the bucket to the
ground before starting the work.
19. Loose or damaged fuel, lubricant and hydraulic
lines, tubes and hoses can cause fires. Do not
bend or strike high pressure lines or install ones
which have been bent or damaged. Inspect
lines, tubes and hoses carefully. Do not check for
leaks with your hands. Very small (pinhole) leaks
can result in a high velocity oil stream that will be
invisible close to the hose. This oil can penetrate
the skin and cause personal injury. Use card-
board or paper to locate pinhole leaks.
20. Tighten connections to the correct torque. Make
sure that all heat shields, clamps and guards are
installed correctly to avoid excessive heat,
vibration or rubbing against other parts during
operation. Shields that protect against oil spray
onto hot exhaust components in event of a line,
tube or seal failure must be installed correctly.
21. Do not operate a machine if any rotating part is
damaged or contacts any other part during
operation. Any high speed rotating component
that has been damaged or altered should be
checked for balance before reusing.
22. Be careful when servicing or separating the
tracks (crawlers). Chips can fly when removing
or installing a track (crawlers) pin. Wear safety
glasses and long sleeve protective clothing.
Tracks (crawlers) can unroll very quickly when
separated. Keep away from front and rear of
machine. The machine can move unexpectedly
when both tracks (crawlers) are disengaged
from the sprockets. Block the machine to prevent
it from moving.
