EHICLE
Drive vehicle onto lift. Set parking brake and/or use
wheel chocks that are provided with lift.
When the vehicle has reached the desired working
height, release the power pack button, and lower
the vehicle until the safety locks are engaged. The
vehicle should remain level when all locks are
engaged. If one side engages and the other
continues to descend, stop lowering the vehicle,
raise it several inches, and try again to engage
locks.
IMPORTANT, before walking under the lift insure
that all locks are properly engaged.
It is not safe to work under the vehicle unless all
locks are engaged, and the vehicle is level.
L
OWERING A VEHICLE
Insure that the area under the vehicle is clear of
personnel and tools.
Raise the vehicle until locks are free.
Disengage the locks by depressing the palm
button and holding it.
Lower the vehicle by depressing the lowering valve
handle. Watch lift to insure that the lift is lowering
evenly. If not, raise lift and check all locks to insure
they are disengaged before trying to lower lift
again.
Continue to lower the vehicle until the crossbeams
stop against the base plate. It is important to fully
lower the lift to release hydraulic pressure on the
system.

lifts with rear slip plates working properly use
compressed air to blow out any debris from
the bearing area.
Check for loose or broken parts.
Check hydraulic system for fluid leaks.
Check lock release activation.

IMPORTANT! Failure to keep lift free of
corrosive agents and solvents will lead to
reduced service life, which could result in
property damage and/or personal injury.
If any problems are encountered, contact
your local service representative.
