SAFETY PRECAUTIONS
SWARNING
The proper and safe lubrication and maintenance
for this machine, recommended by Manufacturer,
are outlined in the OPERATOR’S MANUAL for the
machine.
Improper performance of lubrication or mainte-
nance procedures are dangerous and could result
in injury or death. Read and understand the MAN-
UAL before performing any lubrication or mainte-
nance.
The serviceman or mechanic may be unfamiliar
with many of the systems on this machine. This
makes it important to use caution when perform-
ing service work. A knowledge of the system and or
components is important before the removal or dis-
assembly of any component.
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 de-
cal on the machine before Operating, Maintaining
or Repairing this machine.
(2) Always wear protective glasses and protective
shoes when working around machines. In partic-
ular, wear protective glasses when using ham-
mers, punches or drifts on any part of the machine
or attachments. Use welders gloves, hood/gog-
gles, 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 Oper-
ate" 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 ma-
chine so it does not roll while working on or under
the 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.
SWARNING
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 in-
jury or death.
(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 buck-
et, 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 us-
ing. Always face to the machine when using
steps, ladders and walkways. When it is not pos-
sible 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 com-
ponents 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 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 liquids under pressure. The danger is even
greater if the machine has just been stopped be-
cause fluids can be hot.
(13) Always use the proper tools that are in good con-
dition and that are suited for the job at hand. Be
5. SAFETY PRECAUTIONS
0-4
sure you understand how to use them before per-
forming any service work.
(14) Reinstall all fasteners with the same part number.
Do not use a lesser quality fastener if replace-
ments are necessary.
(15) Repairs which require welding should be per-
formed only with the benefit of the appropriate ref-
erence information and by personnel adequately
trained and knowledgeable in welding proce-
dures. 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 weld-
ing 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 contact-
ing sharp corners, or by rubbing against some ob-
ject 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 possibil-
ity of a falling attachment. Don’t fail to lower the at-
tachment and place the bucket to the ground be-
fore 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 re-
sult in a high velocity oil stream that will be invisi-
ble 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, vibra-
tion or rubbing against other parts during opera-
tion. 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 opera-
tion. 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 install-
ing 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 ma-
chine can move unexpectedly when both tracks
(crawlers) are disengaged from the sprockets.
Block the machine to prevent it from moving.

2.5 TRANSPORTATION
(1) LOADING MACHINE ON A TRAILER
1) Keep trailer bed clean. Put chocks against truck wheels.
2) Use a ramp or loading deck. Ramps must be strong enough, have a low angle, and correct height. Load and
unload machine on a level surface.
3) Travel machine onto ramps slowly. Center the machine over the trailer.
4) Lower all attachment.
5) Stop engine. Remove key from switch.
SWARNING
Do not put chains over or against hydraulic lines or hoses.
6) Fasten machine to trailer with chains or cables.
During transportation, the bucket or attachments may hit the canopy or the cab. Therefore, set the machine in
the transporting position by observing following points:
1.Extend the bucket cylinder fully.
2.Extend the dipper cylinder fully.
3.Lower the boom.
4.If machine cannot be transported with dipper cylinder fully extended, remove bucket or attachment and extend
dipper cylinder.
