Maintenance Under Special Environmental Conditions
Operating Conditions
Precautions for Maintenance
Muddy Soil, Rainy or
Snowy Weather
After Operation
: Clean the machine and check for cracks, damaged, loose or missing bolts
and nuts. Lubricate all necessary parts without delay.
Near the Ocean
After Operation
: The following salt pollution measures must be taken when the machine is
operated at sea or at coastline.
(1) After completing the work, extend/retract the hydraulic cylinders
several times to form 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) Perform touch up painting periodically on hose fittings, lubrication
piping and inserting position of cover, where sea water is easily
collected, in order to prevent corrosion.
(4) During storage of the machine, cover the machine by tarps 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.
Dusty Atmosphere
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.
Engine, Muffler
: Clean earlier than the normal interval to prevent dust from sticking and
accumulating. Inhibit regeneration according to the machine operating
condition.
Rocky Ground
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 before using it, or use a heavy duty bucket.
Falling Stones
Cab Head Guard
: Provide a cab guard to protect the machine from falling stones. Consult
your nearest Hitachi dealer.
Freezing Weather
Fuel/Lubricant
: Use high quality and low viscosity fuel and oil.
Engine Coolant
: Be sure to use antifreeze.
Battery
: Fully charge the batteries at shorter intervals. If not fully charged,
electrolyte may freeze.
Track
: Keep the track clean. Park the machine on a hard surface to prevent the
tracks from freezing to the ground.
