- Safety rules
- ATTENTION Do not operate or perform any
maintenance on this machine until all
instructions found in the OPERA- TORS MANUAL
and this MANUAL have been thoroughly read and
understood. Improper operation or maintenance of
this machine may cause accidents and could result
in serious injury or death. - Always keep the manual in storage.
- If it is missing or damaged, place an order with
an authorized our Distributor for a replacement.
If you have any questions, please consult an
authorized our Distributor. - Most accidents, which occur during operation, are
due to neglect of precautionary measures and
safety rules. Sufficient care should be taken to
avoid these accidents. Erroneous operation,
lubrication or maintenance ser- vices are very
dangerous and may cause injury or death of
personnel. Therefore all precautionary measures,
NOTES, DANGERS, WARNINGS and CAUTIONS contained
in the manual and on the machine should be read
and understood by all personnel before starting
any work with or on the machine. - 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. - Messages of safety appear in the manual and on
the machine All messages of safety are
identified by either word of "DANGER", "WARNING"
and "CAUTION". - Indicates an imminently hazardous situation
which, if not avoided, will result in death or
serious injury and is represented as follows - Indicates a potentially hazardous situation
which, if not avoided, could result in death or
serious injury and is represented as follows - Indicates a potentially hazardous situation
which, if not avoided, may result in minor or
moderate injury. It may also be used to alert
against possible damage to the machine and its
components and is represented as follows - It is very difficult to forecast every danger
that may occur during operation. However, - safety can be ensured by fully understanding
proper operating procedures for this machine
according to methods recommended by Manufacturer. - While operating the machine, be sure to perform
work with great care, so as not to - damage the machine, or allow accidents to occur.
- Continue studying the manual until all Safety,
Operation and Maintenance procedures are
completely understood by all persons working with
the machine.

- INTRODUCTION
- Safety precautions
- ATTENTION The proper and safe lubrication and
maintenance for this machine, recommended by
Manufacturer, are outlined in the OPERATORS
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. - 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. - The following is a list of basic precautions that
must always be observed. - Read and understand all Warning plates and decal
on the machine before Operating, Maintaining or
Repairing this machine. - Always wear protective glasses and protective
shoes when working around machines. In
particular, wear pro- tective 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 cloth- ing before
working on this machinery. - Disconnect the battery and hang a "Do Not
Operate" tag in the Operators Compartment. Remove
ignition keys. - 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 machine. Hang a "Do Not Operate" tag in the
Operators Compartment. - 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.

- 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. - 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. - 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. - The maintenance and repair work while holding the
bucket raised is dangerous due to the possibility
of a falling attachment. Dont fail to lower the
attachment and place the bucket to the ground
before starting the work. - 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. - Tighten connections to the correct torque. Make
sure that all heat shields, clamps and guards are
installed cor- rectly 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. - 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. - 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.
