Precautions for Maintenance
: Clean the machine and check for cracks, damage, loose or missing bolts
and nuts. Lubricate all necessary parts without delay.
: The following salt pollution measures must be taken when the machine is
operated at sea or near the coastline.
(1) After completing the work, extend/retract the hydraulic cylinders
several times to form an oil film on the rod surface. Store the machine
with cylinders retracted as much as possible.
(2) Thoroughly clean the machine with fresh water to wash off salt.
(3) To prevent corrosion, perform touch up painting periodically on hose
fittings, lubrication piping and inserting position of cover, where sea
water is easily collected.
(4) During storage of the machine, cover the machine with tarpaulin
to prevent sea water from entering into the cab vent. Apply rust
prevention oil (example: ANTIRUST P-1300NP-3 JX Nippon Oil &
Energy Corporation) onto plated part of the cylinder rods.
: Clean the radiator to prevent clogging of the radiator core.
: Clean earlier than the normal interval to prevent dust from sticking and
accumulating. Inhibit the aftertreatment device regeneration according
to the machine operating condition.
: Carefully operate while checking for cracks, damage and loose bolts and
nuts. Loosen the tracks a little more than usual.
Reinforce the bucket before using it, or use a heavy duty bucket.
: Provide a cab guard to protect the machine from falling stones. Consult
your nearest Hitachi dealer.
: Use high quality and low viscosity fuel and oil.
: Be sure to use antifreeze.
: Fully charge the batteries at shorter intervals. If not fully charged,
electrolyte may freeze.
: Keep the tracks clean. Park the machine on a hard surface to prevent the
tracks from freezing to the ground.
: May become frozen but the machine can be operated normally.
