• Replace the coolant every year.
[7] ELECTRICAL PART HANDLING
• A current leakage is developed if the electrical parts are wetted or have damaged coating,
which causes the machine to go out of order and malfunction.
• Inspection and maintenance include the checking of belt tension, belt damage, and battery
electrolyte level.
• Never remove and disassemble equipment (electrical parts) from the machine.
• Only optional electrical parts that accompany the machine can be installed.
• Keep the electrical parts away from water when the machine is washed and used in the rain.
• When using the machine on coastal areas, keep the electrical parts free of water and impurities
to prevent corrosion.
[8] HYDRAULIC EQUIPMENT HANDLING
• Hydraulic equipment will be at elevated temperatures during and immediately after operation.
Hydraulic equipment operates under high pressure.
The following precautions should be observed when performing inspection and maintenance of
hydraulic equipment.
• Place the machine in travel position on a level surface to inhibit the application of pressure to
the cylinder circuit.
• Be sure to stop the engine.
• Hydraulic oil and lubricating oil will be at elevated temperatures and high pressure
immediately after equipment comes to a stop. Perform inspection and maintenance only after
the oil drop in temperature for safety. An internal pressure may be exerted despite
temperature drop. When removing the plugs, screws and hose joints, stand aside and provide
gradual loosening to decompress.
• Be sure to release the pressure by removing the air from the hydraulic oil tank before
performing inspection and maintenance of the hydraulic circuit.
• Inspection and maintenance include hydraulic oil level check and replacement of the filters and
hydraulic oil.
• Check the O-ring for scratches when removing the high-pressure hose. If scratches are found,
replace it.
• Bleeding the air from the hydraulic circuit is required after the following tasks are performed:
replacement and cleaning of the hydraulic oil filter element and strainer, repair and
replacement of hydraulic equipment, and hydraulic piping removal.
