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.
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. The
cylinders are self-bleeding.
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 make odd noises
when in use.
Lubricate hinge points using White Lithium Grease.
Lubricate the platforms where the Slide Blocks travel using White
Lithium Grease.
Platforms are slowly
lowering on their own.
Make sure both Platforms are on Safety Locks.
Only leave the Lift fully lowered or engaged on Safety Locks.
Look for Hydraulic Fluid leaks.
Lift Frames cannot not rise
from a zero net rise position
with weight on the lift.
The MDS-6 Series Lift cannot raise a full load from a completely flat
position. Refer to
Vehicle with No Tires Fully Lowered
If you continue to have problems with your Lift, take the Lift out of service, then contact your dealer,
, or call
(800) 253-2363
,
extension 196.
Vehicle with No Tires - Fully Lowered
When the MDS-6 Series Lift is completely flat and there is too much weight on the Lift Platform, there
is no room to develop any upward force. The weight on the Lift must be reduced by at least half or
raise the Vehicle off the Lift Platform or Lift Pads in some other manner.
Methods that have resolved this issue include:
•
Use a floor jack to raise the Vehicle from four to six inches.
•
Using lifting equipment to raise the Vehicle. If you are still unable to raise your Vehicle, contact
BendPak Technical Support for assistance.
