6. Troubleshooting
Common lift issues may be encountered over time. Please see probable causes & possible solutions covered
in the paragraphs below. If the troubleshooting guide does not provide assistance to resolve the lift issue(s),
please contact the distributor / manufacturer for help. We will help you solve the problem as soon as possible.
Ø
Motor Does Not Operate:
1. Breaker or fuse blown
…………(Contact Electrician)
2. Faulty wiring connections
……..(Contact Electrician)
3. Defective start / up button
…….(Contact Electrician)
WARNING!!
Failure to properly relieve pressure in the following steps can cause injury to personnel.
Ø
Motor Functions but Lift Will Not Rise:
1. Power Unit is not priming correctly
……..(See Power Unit Prime Procedure on next page.)
2. A piece of trash is under release
‘down’ valve…..(Push lowering handle down, while pushing the start /
up button at the same time. Hold for 10-15 seconds. This should flush debris from release valve.)
3. Motor spins backwards
…..(Carefully remove the check valve cover and clean check ball, spring & seat.)
4. Oil level too low
….(Oil level should be at the MAX fill line located on the reservoir tank when lift is fully
lowered.)
NOTE: Ensure to fully lower lift to relieve all hydraulic pressure before adding add oil.
Ø
Oil Blows out Breather of Power Unit:
1. Oil reservoir tank overfilled
…(Relieve all pressure and siphon out hydraulic fluid until at a proper level.)
2. Lift lowered too quickly while under a heavy load
….(Lower the lift slowly under heavy loads.)
Ø
Motor Hums and Will Not Run:
1. Lift overloaded
…..(Remove excessive weight from lift.)
WARNING!!
The voltages used in the lift can cause death or injury. In the following steps, make sure
that a qualified electrician is used to perform maintenance.
2. Faulty wiring
………… (Contact Electrician)
3. Bad capacitor
……….. (Contact Electrician)
4. Low voltage
…………..(Contact Electrician)
Ø
Lift Jerks Going Up and Down:
1. If the lift jerks while going up and down, it is usually a sign of air in the hydraulic system
…..(Raise lift all
the way to top and return to floor. Repeat 4-6 times, ensuring not overheat power unit.)
Ø
Oil Leaks:
1. Power Unit: if the power unit leaks hydraulic oil around the tank-mount flange, check the oil level in the
tank. The level should be two inches below the flange of the tank when the lift is fully lowered.
2. Cylinder / Piston Rod: the rod seal of the cylinder is defective. Rebuild or replace the cylinder.
3. Cylinder / Vent: the piston seal of the cylinder is out. Rebuild or replace the cylinder.
Ø
Lift makes Excessive Noise / Vibrates:
1. Cross beam ends are rubbing the columns
……..(Re-adjustment needed.)
2. Cylinder too tight
……..(load lift half capacity and cycle up and down a few times to break in seals.)
3. Possible excessive wear to cable sheaves and shafts
…..(Replace as required.)
