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 at least equivalent to that of the parent
metal. Disconnect battery before any welding procedures are attempted.
16. Do not damage wiring during repair/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. Make 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 complete.
18. Performing maintenance or repair work on the machine with the bucket/attachment raised is
hazardous. The bucket/attachment and lift arm could fall and injure or kill a person. Be sure to
lower the bucket or attachment to the ground before starting work on the machine.
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 parts which are 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 a small piece of card-board, wood or metal 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.
23. Caution should be used to avoid breathing dust that may be generated when handling components
containing asbestos fibers. If this dust is inhaled, it can be hazardous to your health. Components
in Manufacture products that may contain asbestos fibers are brake pads, brake band and lining
assembles, clutch plates and some gaskets. The asbestos used in these components is usually
bound in a resin or sealed in some way. Normal handling is not hazardous as long as air-borne
dust which contains asbestos is not generated.
AVOID INJURY OR DEATH (In 5. Regard)
Do not operate this machine unless you have read and understand the instructions in this operator's
manual. Improper machine operation is dangerous and could result in injury or death.
