4 Lift lock solenoid
(1) When the seat switch and the load handling
neutral safety switch are engaged, the lift
lock solenoid is energized.
(2) The voltage between the CN1P-35 terminal
and the negative (-) terminal.
Key switch ON (with seat switch ON): 36 V

5. Pump motor rotation sensor
(1) Detects the pump motor speed.
(2) When the pump motor runs, a pulsed voltage
is generated between CN2P-5 and CN2P-16
terminals.

6. Pump motor thermosensor
(1) Detects the drive motor temperature.
(2) When the sensor detects a temperature of
145ºC [293ºF] or above, the symbol
406
appears on the LCD panel, the
blinks,
and the motor output is limited.
(3) When the sensor detects a temperature
of 156ºC [312.8 ºF] or above, the symbol
405 appears on the LCD panel, the
blinks, and the motor is stopped.
