Troubleshooting
This section describes how to troubleshoot your Lift.
Note
: If your Lift is not functioning correctly, you must take it out of service until it is fixed.
Important
: All repair work
must
be done by qualified personnel.
⚠
WARNING
The Lift uses electrical energy; if your organization has Lockout/Tagout policies,
make sure to implement them before performing any Troubleshooting.
Runways do not raise or do not
lower, once raised.
Make sure there is sufficient Hydraulic Fluid in the reservoir.
Make sure there is no air in the Hydraulic System.
Make sure the Hydraulic Hose is not pinched or leaking.
Make sure the Power Unit is getting power.
If the Hydraulic Fluid is dirty, replace it with clean fluid.
Make sure the Lift is not overloaded.
Runways do not lower past the
nearest Safety Lock when pressing
and holding the pushbutton.
Problem with the Air Line; check to make sure all sections of
the Air Line are connected and not leaking.
One corner of the Lift is lower than
the other three corners.
The Safety Lock on the lower corner is not engaged. Raise the
Runways up, then lower them down onto the Safety Locks.
Check to make sure all four Safety Locks are engaged.
Runways move erratically or squeak
when in use.
Move the Runways up and down a few times to flush any
residual air from the Hydraulic System. Make sure to pause for
at least two minutes between cycles.
Runways do not stay up.
Check for leaking Hydraulic Fluid.
Make sure the Runways are engaged on their Safety Locks.
Motor not running.
Check the connection to the power source; make sure it is
plugged in and of the appropriate voltage.
Make sure the wiring is correct; check the wiring diagram.
Hydraulic Fluid is dirty.
Replace the dirty fluid with clean, approved Hydraulic Fluid,
such as Dexron III, Dexron VI, Mercon V, Mercon LV, Shell
Tellus S4 / S3 / S2, or comparable.
Runways make odd noises.
Lubricate the bushings on the Sheaves on the sides of the
Crosstubes using white lithium grease. If the Lift is new, a
break-in period may be needed; run the Lift several times
each day. If the noises persist, contact BendPak Support.
If you continue to have issues with your Lift, take it out of service, then contact your dealer, go to
or call
