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).
Precautions for Maintenance
: Check tightness of plugs and all drain cocks.
: Clean the machine and check for cracks and damage. Check for loose or
missing bolts and nuts. Lubricate all necessary parts without delay.
If the machine should be submerged in water deeper than approximately 450
mm, water may get into the brake device (such as the parking brake), resulting
in poor braking performance. Watch out when starting/stopping the machine.
: Check tightness of plug and all drain cocks.
: Thoroughly clean the machine with fresh water to wash off salt.
Service electrical equipment often to prevent corrosion.
: Clean the element regularly at shorter service intervals.
: Clean the radiator core and every coolers core.
: Clean the filter element and strainer regularly at shorter service intervals.
: Clean them regularly, in particular, the commutator surface of the alternator
and starter.
: Clean earlier than the normal interval to prevent dust from sticking and
accumulating. Inhibit regeneration according to the machine operating
condition.
: Check for damage on tires, for loose, cracked, worn, and damaged bolts and
nuts.
: Standard attachment may be damaged when digging rocky ground.
Reinforce the bucket before using it, or use a heavy duty bucket. Consult your
authorized dealer.
: Use high quality fuel suitable for low temperature.
Check the fuel tank breather pipe freezing.
: Use high quality low viscosity hydraulic oil and engine oil.
: Be sure to use antifreeze.
: Fully charge the batteries regularly at shorter service intervals. If not charged
fully, electrolyte may freeze.
: Keep tires and frames clean. Park the machine on a hard surface to prevent the
tires from freezing to the ground.
: May become frozen but the machine can be operated normally.
: 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.
: Clean the element at shorter intervals.
: Clean and replace the elements and the filters at shorter intervals.
: Remove the accumulated paper and/or waste from the surroundings around
the loader frame and the attachment. Failure to do so may cause damage of
the machine.
: Wash as frequently as possible to prevent corrosion due to chemical materials.
