Before Operation:
Check the tightness of plugs and all drain cocks.
After Operation:
Thoroughly clean the machine with fresh water to
wash off salt. Service electrical equipment often
to prevent corrosion.
Air Cleaner:
Clean the element regularly, at shorter service
intervals.
Radiator:
Clean the oil cooler screen to prevent clogging of
the radiator core.
Fuel System:
Clean the filter element and strainer regularly, at
shorter service intervals.
Electrical Equipment:
Clean them regularly, in particular, the commu-
tator surface of the alternator and starter.
Tracks:
Carefully operate while checking for cracks,
damage and loose bolts and nuts. Loosen the
tracks a little more than usual.
Front Attachment:
Standard attachment may be damaged when
digging rocky ground. Reinforce the bucket be-
fore using it, or use a heavy duty bucket.
Fuel:
Use high quality fuel suitable for low temperature.
Lubricant:
Use high quality low viscosity hydraulic oil and
engine oil.
Engine Coolant:
Be sure to use antifreeze.
Battery:
Fully charge the batteries regularly with shorter
service intervals. If not charged fully, electrolyte
may freeze.
Tracks:
Keep the tracks clean. Park the machine on a
hard surface to prevent the tracks from freezing
to the ground.
Cab:
Provide a cab guard to protect the machine from
falling stones when necessary.
Engine oil:
Change at 1/2 normal service intervals.
Engine oil filter:
Replace at 1/2 normal service intervals.
※ When the machine is operated at the altitudes of 2000 m (6600 ft)or
higher, the ignition of the engine may be deteriorate, possibly resulting
in significant reduction in durability or function. In case the machine is
unavoidably operated under these conditions, consult your authorized
dealer in advance.
