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).
 Avoid driving the machine into a river where
Precautions for Maintenance
: 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.
: 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 when indicator
illuminates.
: Clean the oil cooler and the radiator cores.
: Clean the filter element and strainer regularly at shorter service intervals.
: Clean them frequently to prevent deposits or dirt.
Apply "Aftertreatment Device Regeneration Inhibit" setting as needed.
: Clean them regularly, in particular, the commutator surface of the alternator
and starter.
: Check for damage on tires, for loose, cracked, worn, and damaged bolts and
nuts.
heavy duty bucket. Consult your nearest 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.
tires from freezing to the ground.
: Keep 80% of tank capacity when storing at -10°C (12°F) or lower. The DEF tank
maybe broken if DEF is frozen.
: 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 chassis 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.
