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 rotating the mechanical
lock handle clockwise.
Lower the vehicle by depressing the lowering valve
handle and continue to hold mechanical lock
handle to keep locks disengaged. 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.
