MAINTENANCE UNDER SPECIAL ENVIRONMENTAL CONDITIONS

Maintenance Under Special Environmental Conditions
Operating Conditions
Muddy Soil, Rainy or
Snowy Weather
Near the Ocean
Dusty Atmosphere
Rocky Ground
Falling Stones
Freezing Weather
High Altitude
(Altitude: 1500 m or
higher)
When the machine is operated at the altitude 1500 m or higher, the ignition of the engine may deteriorate, possibly
resulting in significant decrease in durability or function. If the machine is unavoidably operated under these conditions,
consult your authorized Hitachi dealer.
After Operation Clean the machine and check for cracks, damaged, loose or missing bolts
and nuts. Lubricate all necessary parts without delay.
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.
Air Cleaner Clean the filter element and strainer 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 Parts Clean the commutator especially for the starter and alternator.
Engine, Muffler Clean earlier than the normal interval to prevent dust from sticking and
accumulating. Inhibit regeneration according to the machine operating
condition.
Track Carefully operate while checking for cracks, damage and loose bolts and
nuts.
Do not use rubber crawlers.
Front Attachment Standard attachment may be damaged when digging rocky ground.
Reinforce the bucket before using it, or use a heavy duty bucket.
Cab Head Guard Provide a cab guard to protect the machine from falling stones. Consult
your nearest Hitachi dealer.
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.
Engine Oil Change at 1/2 of normal service interval.
Engine Oil Filter Change at 1/2 of normal service interval.
