Precautions for Maintenance
Check the tightness of plugs and all drain cocks.
Clean the machine and check for cracks, dam-
aged, loose or missing bolts and nuts. Lubricate
all necessary part without delay.
Check the tightness of plugs and all drain cocks.
Thoroughly clean the machine with fresh water to
wash off salt. Service electrical equipment often
to prevent corrosion.
Clean the element regularly, at shorter service
intervals.
Clean the oil cooler screen to prevent clogging of
the radiator core.
Clean the filter element and strainer regularly, at
shorter service intervals.
Clean them regularly, in particular, the commu-
tator surface of the alternator and starter.
Carefully operate while checking for cracks,
damage and loose bolts and nuts. Loosen the
tracks a little more than usual.
Standard attachment may be damaged when
digging rocky ground. Reinforce the bucket be-
fore using it, or use a heavy duty bucket.
Use high quality fuel suitable for low tempera-
ture.
Use high quality low viscosity hydraulic oil and
engine oil.
Be sure to use antifreeze.
Fully charge the batteries regularly with shorter
service intervals. If not charged fully, electrolyte
may freeze.
Keep the tracks clean. Park the machine on a
hard surface to prevent the tracks from freezing
to the ground.
Provide a cab guard to protect the machine from
falling stones when necessary.
