1.1. Lift

When the lift button is pushed, the lift pump solenoid is
energized starting the pump and motor. Fluid is drawn from
the reservoir, through a pick up screen to the inlet of the gear
pump. As the gear pump rotates, oil is forced out the pressure
port and is blocked from returning to the reservoir by a closed
relief valve and lowering valve. Oil continues to flow to the top
of the lift cylinder and pushes against the end of cylinder rod
to extend the rod from the cylinder tube. When the lift pump
motor is shut off and the gear pump is not turning, the
cylinder is held extended by a closed check valve and
normally closed lowering valve.
