4. Conduct 5-minute warm-up after the electric motor is started.
NOTES
This machine is structured to switch to the energy-saving mode if no lever operation is attempted within
5 minutes after the electric motor is started.
Once the energy-saving mode has been entered, the electric motor undergoes an extreme reduction in
rotational speed. Operate any lever for recovery from the energy-saving mode. The electric motor
comes to a stop if no lever operation is attempted within further 30 minutes after being started. Turn the
starter switch to the “START” position again for recovery.
5. Visually check through the access protective cover of the
Inverter unit that the trouble lamp remains OFF.
CAUTION
An error occurs in the Inverter unit, which causes the
trouble lamp to come ON in red.
Contact us or our sales service agency to request
inspection and repair in the above event.
6. Use the following procedure for checking the power unit if an
abnormal noise, odor, or vibration is present in and around the
power unit.
(1) Turn the starter switch key to the “OFF” position.
The electric motor comes to a stop.
(2) Remove the four mounting bolts (2) securing the bottom of
the power unit cover (1) and remove the power unit cover (1).
(3) Check the mounting bolts securing the electric motor (3) and
hydraulic pump (4) for looseness and falling off, and check
the coupling (5) for looseness.
If check finds looseness, torque the bolts to the specified
value to provide retightening.
(4) Keep the periphery of the power unit free of dead leaves,
paper waste, and dust.
Eliminate dead leaves, paper waste, and dust if heaped or
adhered.
(5) Install the power unit cover (1) in inverse order of their
removal upon completion of inspection and cleaning.
