Operating Instructions and Parts Manual
Preparation
Always secure the handle into the handle sleeve
by means of the bolt lock washer and nut provided.
Tighten securely to prevent accidental removal of
handle while in use.
BEFORE USE
1. Verify that the product and application are
compatible.
2. Before using this product, read the operator's
manual completely and familiarize yourself
thoroughly with the product, its components and
recognize the hazards associated with its use.
3. To familiarize yourself with basic operation, turn the
release valve (handle knob):
a. Clockwise until firm resistance is felt to further
turning. This is the 'CLOSED' release valve
position used to raise the saddle.
b. Counter-clockwise, but no more than 1/2 turn
from the closed position. This is the 'OPEN'
release valve position used to lower the saddle.
4. With saddle fully lowered and release valve fully
closed, pump the operating handle. If lift arm
responds immediately, jack is ready for use. If jack
does not respond, follow Bleeding/Venting Trapped
Air instruction below.
5. Air Operated models: Pour a teaspoon of good
quality, air tool lubricant into the air supply inlet
of the lift control valve. Connect to air supply and
operate for 3 seconds to evenly distribute lubricant.
:
NOTICE
Air Operated jacks are equipped with a 1/4"
NPT air coupler. If installing a different air coupler,
ensure that thread tape or compound is used when
servicing connections. To ensure dependable,
trouble free operation an in-line air dryer and oiler is
recommended.
6. Ensure that jack rolls freely. Raise and lower the
unloaded saddle throughout the lifting range before
putting into service to ensure the pump operates
smoothly. Replace worn or damaged parts and
assemblies with authorized replacement parts only.
Bleeding/Venting Trapped Air
With the release valve in the OPEN position (step
3b. above) and with saddle fully lowered, locate and
remove the air vent screw. Pump 6 to 8 full strokes.
This will help release any pressurized air which may
be trapped within the reservoir. Proper oil level will
vary from just covering the ram cylinder to 3/16" (,45
cm) above it as seen from the oil filler hole. Reinstall
the air vent screw.

Operation
LIFTING
Only attachments and/or adapters
supplied by the manufacturer shall be used.
:
NOTICE
These jacks are equipped with handle
position locks. To adjust the handle, release lock
device by pulling the lever up, then back until lever is
locked into place.
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. Locate and close the release valve by turning the
release valve knob 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 or foot pedal to
contact lift point. To lift, pump handle or squeeze lift
control valve until load reaches desired height. Do
not use foot pedal to raise load.
Do not wire, clamp or otherwise disable the lift control
valve to function by other than operator's hand.
5. Transfer the load to appropriately rated jack stands.
LOWERING
Clear all tools and personnel
before lowering load. Open the release valve
slowly. The further the release valve knob is
turned counter-clockwise, the faster the load will
descend. Maintain control of the load at all times.
1. Raise load high enough to clear the jack stands.
2. Remove jack stands.
3. Turn the release valve knob 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. Remove jack from under vehicle and fully lower
the saddle to reduce ram exposure to rust and
contamination.
