KNOW YOUR JACK
(refer to Fig. 3, page 4)
• Compare these illustrations with your jack
BEFORE operation and/or oil level
maintenance to become familiar with the
location of various jack components.
BEFORE USE
Occasionally during shipment and/or
handling, air gets trapped in the hydraulic
s y s t e m , w h i c h i n t e r f e r e s w i t h j a c k
performance. To release this trapped air do
the following:
1. Using the end of the assembled handle
which is formed to fit the release valve,
engage and open the release valve by
turning it counterclockwise no more than
1/2 full turn from a fully closed position.
2. With the jack in the upright position,
remove the oil filler plug. Insert the handle
into the handle socket, then pump 6 to 8
full strokes.
3. Ensure that the oil is level with the oil filler
plug hole, then reinstall oil filler plug. If low,
add oil as described in the Maintenance
Section (see page 7).
4. Ensure that the pump operates smoothly
before putting into service. Lubricate as
instructed in the Maintenance Section (see
page 7).
OPERATING PRINCIPLES
• With the release valve closed, an upward
stroke of the jack handle draws oil from the
reservoir tank into the plunger cavity.
Hydraulic pressure holds the valve closed,
which keeps the oil in the plunger cavity.
• A downward stroke of the jack handle
releases oil into the cylinder, which forces
the ram out and raises the saddle.
• W h e n t h e r a m r e a c h e s m a x i m u m
extension, oil is bypassed back into the
reservoir to prevent an overextended ram
stroke and possible damage to the jack.
• Opening the release valve allows oil to flow
back into the reservoir. This releases
hydraulic pressure on the ram, which
results in lowering the saddle.
OPERATION
HOW TO USE YOUR JACK
(refer to Fig. 3, page 4)
RAISING THE JACK
1. When lifting a vehicle, place the vehicle in
park, engage emergency brake and chock
the tire(s) diagonally opposite the tire(s)
being raised to prevent inadvertent
movement forward and backward. Use
wheel chocks which are rated for the tire
dimension of your vehicle.
2. Locate the release valve and, using the
provided handle, engage the release valve
and turn handle clockwise until firm
resistance to further thread engagement
is felt. Center the jack saddle under
manufacturers recommended lift point.
To avoid crushing injuries and
property damage:
NEVER
place yourself
or others under a load for the purpose of
pumping the handle socket. Use
ONLY
the
handle provided.
3. Verify lift point, insert handle into the
handle socket and pump to contact the lift
point. To lift, continue pumping until load
reaches desired height.
4. Immediately after lifting, transfer the load
to a pair of appropriately rated jack stands.
Rated capacity of jack stands is
per
pair
, it is
NOT
the sum of individual
capacities unless specifically noted to the
contrary by the jack stand manufacturer.
Do Not
exceed rated capacity.
Ensure
that the vehicle support points are fully
captured between the outer lugs of both
jack stands.
Use
a matched pair of jack
stands
per
vehicle to support
1
end
only
.
Use
1 pair per vehicle
only
. Failure to do
so may result in sudden loss of load, which
may cause personal injury and/or property
damage.
