Functional Description; Lift Circuit; During Lifting - Toyota 7FBEF 15 Service Manual

I Functional description
General
1. This vehicle is equipped with the key-off lift lock function using a solenoid valve provided in the lift
circuit similarly as on the 7FB10-J35 series.
2. Since tilt lock is electrically controlled by the solenoid valve installed in the forward tilt circuit, the
conventional tilt lock valve has been discontinued.
3. Since the flow is controlled by pump motor revolution similarly as on the 7FB10-J35 series, no solenoid
valve is provided on the control valve side.

Lift circuit

1. During lifting (lift solenoid valve: ON)
(1) When the lift lever is operated in the lifting direction, the lift spool moves to the left in the figure.
Then, the pump pressure compresses the spring at the lift load check valve to open the valve.
(2) The pump pressure is led to the lift logic valve. The pressure compresses the spring at the lift logic
valve to open it.
(3) As the result, the pump pressure is led to the C1 port to extend the lift cylinder and raise the fork.
