Troubleshooting
This section describes how to troubleshoot your Lift.
The Lift uses electrical and pneumatic energy; if your organization has Lockout/Tagout policies,
implement them before performing any troubleshooting.
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.
Issue
Action to Take
Platforms move erratically
or squeak when in use.
Move the Platforms up and down a few times, with a break between
each; there could be residual air in the Hydraulic System.
Platforms do not go up or
down.
Make sure the Power Unit is connected to an appropriate power
source.
Make sure none of the Hydraulic Hoses are pinched or leaking.
Make sure there is sufficient Hydraulic Fluid in the reservoir on the
Power Unit.
Hydraulic Fluid is old or
dirty.
Replace the dirty fluid with clean, approved Hydraulic Fluids, such as
Dexron III, Dexron VI, Mercon V, Mercon LV, Shell Tellus S4 / S3 /
S2, or comparable.
Platforms do not rise from a
zero net rise position.
Platforms cannot raise the weight of a Vehicle from a completely flat
position; that is, the wheels are removed and the Lift is fully lowered.
The Platforms need some space to get upward force started. Refer
to
Fully Lowered Vehicle with No Wheels
below.
Platforms make odd noises
when in use.
Lubricate hinge points using white lithium grease.
Platforms are slowly
lowering on their own.
Make sure both Platforms are on Safety Locks (if not, Hydraulic Fluid
could be leaking out, lowering the Platforms). Only leave the Lift
either fully lowered or engaged on a Safety Lock.
If you continue to have problems with your Lift, contact your dealer, visit
, or call
(800) 253-2363
, extension 196.
Fully Lowered Vehicle with No Wheels
The issue is that there is too much weight on the Platforms with no room to get upward force started.
To fix this issue, you need to reduce the weight on the Platforms by at least half or raise the Vehicle off
the Platforms some other way.
Methods that have fixed this issue include:
•
Use floor jacks to raise the Vehicle up four inches or higher.
•
Use a lifting device to raise the Vehicle up four inches or higher.
If you are still unable to raise your Vehicle, contact BendPak Technical Support for assistance.
