(13)Always use the proper tools that are in good condi-
tion 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 per-
formed only with the benefit of the appropriate ref-
erence 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 dis-
connect 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 contain-
ing fluid.
(17)Be sure all protective devices including guards and
shields are properly installed and functioning cor-
rectly 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 attach-
ment 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 in-
stalled correctly to avoid excessive heat, vibration
or rubbing against other parts during operation.
Shields that protect against oil spray onto hot ex-
haust 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 machine can
move unexpectedly when both tracks (crawlers)
are disengaged from the sprockets. Block the ma-
chine to prevent it from moving.
