Precaution for inspection and maintenance of hydraulic parts
Stop the equipment on a flat and solid ground surface. Put attachments down on the ground and
stop the engine. Do not perform maintenance immediately after work. Wait until the entire
equipment is completely cooled down. If the equipment is still hot and hydraulic parts have
residual pressure, the user can be seriously injured by spurting of hot operating oil. Residual
pressure inside the operating oil tank must be removed before performing maintenance on
hydraulic parts. Operate the working lever in the operating room many times to remove pressure
remaining in the hydraulic circuit. Keep body parts and face away from the workpiece when
loosening plugs and screws on the hydraulic line.
Warning sign during inspection and maintenance
To prevent persons other than the maintenance worker from moving the equipment during
inspection or maintenance, hang a warning sign for "Under maintenance" or "Inspection in
process" in the operating room or on the work lever.
Use appropriate tools.
Stop the engine to conduct inspection or maintenance on the equipment.
Keep the equipment clean.
Water can cause malfunctioning of electric devices.
Do not touch moving parts of the equipment with hands.
Be careful about high pressure of operating oil in the hydraulic circuit.
