Be sure all tools and personnel are clear
before lowering load.
Slowly open the
release valve!
The more you turn the handle counter-
clockwise, the faster the load will come down.
Maintain
control
of the rate of speed at which the load lowers
at all times!
1. Raise load high enough to clear the jack stands.
2. Remove jack stands carefully (
always
used in pairs).
3.
Slowly
turn the handle counter-clockwise, but no
more than 1/2 full turn.
If the load fails to lower:
a. Use another jack to raise the vehicle high
enough to reinstall jack stands.
b. Remove the malfunctioning jack and then the
jack stands.
c. Use the functioning jack to lower the vehicle.
4. After removing jack from under the vehicle, fully
lower the saddle to reduce ram exposure to rust and
contamination.
!
Lowering
NEVER
use hydraulic jack as a stand
alone device!
ALWAYS
transfer the lifted load
IMMEDIATELY
to a pair of appropriately rated jack
stands. Use one pair of jack stands per vehicle.
Rated capacity is per pair only! Do not exceed rated
capacity.
!
1. Follow the vehicle manufacturer’s recommended
guidelines for lifting. Engage the emergency brake
and chock each unlifted wheel in both directions to
prevent inadvertent vehicle movement.
2. Close the release valve by turning the handle clockwise
until firm resistance is felt.
3. Refer to the vehicle manufacturer owner’s manual to
locate approved lifting points on the vehicle. Center
jack saddle under lift point.
4. Verify lift point, then pump handle to contact lift point.
To lift, pump handle
or
squeeze lift control valve until
load reaches desired height. Release grip on lift
control valve to stop lifting if using air function.
5. Transfer the load
immediately
to appropriately rated
jack stands.
NOTICE
: NEVER
operate air motor and pump
handle simultaneously! Doing so will not increase the
lifting capacity of the device and will likely damage
the hydraulic unit.
