MAINTENANCE UNDER SPECIAL ENVIRONMENTAL CONDITIONS
Operating
Conditions
Precautions for Maintenance
Muddy Soil, Rainy
or Snowy Weather
Before Operation: : Check tightness of plugs and all drain cocks.
After Operation : Clean the machine and check for cracks and damage. Check for loose or
missing bolts and nuts. Lubricate all necessary parts.
If the machine should be submerged in water more than approximately 450
mm, water may get into the brake device (like the park brake), resulting in
poor braking performance. Watch out when starting/stopping the machine.
Near the Ocean
(or near chemical
treatment place)
Before Operation: : Check tightness of plug and all drain cocks.
After Operation : Thoroughly clean the machine with fresh water to wash off salt.
Service electrical equipment often to prevent corrosion.
Dusty
Atmosphere
Air Cleaner : Clean the element regularly at shorter service intervals when indicator
illuminates.
Radiator : Clean the oil cooler and the radiator cores.
Fuel, DEF/AdBlue® : Clean the filter element and strainer regularly at shorter service intervals.
Aftertreatment Device,
Engine
: Clean them frequently to prevent deposits or dirt.
Apply “Aftertreatment Device Regeneration Inhibit” setting as needed.
Electrical Equipment : Clean them regularly, in particular, the commutator surface of the alternator
and starter.
Rocky Ground Chassis : Check for damage on tires, for loose, cracked, worn, and damaged bolts and
nuts.
Front Attachment: : Standard attachment may be damaged when digging rocky ground. Use a
heavy duty bucket. Consult your nearest authorized dealer.
Freezing Weather Fuel : Use high quality fuel suitable for low temperature.
Check the fuel tank breather pipe freezing.
Lubricant : Use high quality low viscosity hydraulic oil and engine oil.
Engine Coolant : Be sure to use antifreeze.
Battery : Fully charge the batteries regularly at shorter service intervals. If not
charged fully, electrolyte may freeze.
Tires and Chassis : Keep fires and chassis clean. Park the machine on a hard surface to prevent
the tires from freezing to the ground.
DEF/AdBlue® : Keep 80% of tank capacity when storing at -10°C (12°F) or lower. The DEF/
AdBlue® tank maybe broken if DEF/AdBlue® is frozen.
When handling
old paper and/or
industrial waste
Engine compartment : Remove old paper and/or waste accumulated around the radiator and
in the engine compartment, possibly causing overheating or fires of the
machine if not removed.
Air cleaner : Clean the element at shorter intervals.
Fuel system : Clean and replace the elements and the filters at shorter intervals.
Loader chassis : Remove the accumulated paper and/or waste from the surroundings
around the loader chassis and the attachment. Failure to do so may cause
damage of the machine.
Radiator : Wash as frequently as possible to prevent corrosion due to chemical
materials.
IMPORTANT: If material to be handled is a substance that causes corrosion such as salt or chemical, consult your
nearest authorized dealer. Special modification or treatment may be needed for the machine. If the machine
continues to be used, malfunction may occur due to corrosion.
Consult your nearest authorized dealer when the machine is operated under special condition (s).
Maintenance Under Special Environmental Conditions
d
WARNING: Before operating the machine in a
river, check the riverbed conditions in advance.
d
