B. Motor thermal overload tripped. Wait for overload to cool.
C. Check thermal overload in starter box (3 phase only). Push reset.
D. Faulty wiring connections. Check wiring diagram.
2. Motor runs but the lift will not rise
A. A foreign object is lodged under check valve. As you are running the
pumping unit, push or hold a load in and out several times on the
lowering valve. This should release any foreign objects trapped in the
pump.
B. Remove check valve. Clean the ball and seat, and replace if
necessary.
C. Oil level low. Check reservoir. With lift in the down position, the pump
reservoir should be full.
3. Motor runs but the lift picks up partial load only
A. Lift is overloaded. Check lifts capacity and weight of vehicle.
B. Relief valve setting is too low. Remove hex head plug in the center of
the pump and adjust pressure setting valve.
4. Oil blows out breather
A. Oil reservoir overfilled.
B. Lift lowered too quickly while under heavy load.
5. Lift makes groaning sound when rising
Bleed cylinder manually. Trapped air can cause groaning noise when
rising or lowering lift.
6. Lift rises unevenly.
