TIONS contained in the manual and on the ma-
chine should be read and understood by all per-
sonnel before starting any work with or on the ma-
chine.
2. Operation, inspection, and maintenance should
be carefully carried out, and safety must be given
the first priority. Messages of safety are indicated
with marks. The safety information contained in
the manual is intended only to supplement safety
codes, insurance requirements, local laws, rules
and regulations.
3. Messages of safety appear in the manual and on
the machine :All messages of safety are identi-
fied by eighter word of "DANGER", "WARNING"
and "CAUTION".

SAFETY PRECAUTIONS
The following is a list of basic precautions that must
always 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 par-
ticular, wear protective glasses when using ham-
mers, punches or drifts on any part of the ma-
chine or attachments. Use welders gloves, hood/
goggles, apron and the protective clothing appro-
priate 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.
& WARNING &
Do not operate this machine unless you have read
and understand the instructions in the
OPERATOR'S MANUAL. Improper machine op-
eration 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 dis-
connected 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 correctly to prevent it from dropping un-
expectedly.
8. Use steps and grab handles when mounting or
dismounting a machine. Clean any mud or de-
bris from steps, walkways or work platforms be-
fore using. Always face to the machine when us-
ing steps, ladders and walkways. When it is not
possible to use the designed access system, pro-
vide ladders, scaffolds, or work platforms to per-
form safe repair operations.
9. To avoid back injury, use a hoist when lifting com-
ponents which weigh 20kg (45Ibs) 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. Toavoid 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. Gradu-
ally back off the last two capscrews or nuts lo-
cated 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 con-
dition 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 replace-
ments are necessary.
15. Repairs which require welding should be per-
formed only with the benefit of the appropriate
reference information and by personnel ad-
equately 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.

SAFETY PRECAUTIONS
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 con-
tacting 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 function-
ing 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 possi-
bility 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 in-
visible 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 op-
eration. 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 in-
stalling 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.
