HOW TO ASSEMBLE YOUR JACK
(refer to Figs. 1, 2)
Inside the box, you will find (see Fig. 1):
1. A jack
• Install the rubber handle holder onto the
top nut and slide downward until it rests
upon the reservoir of the jack. Orient the
holder portion away from the handle socket
so that it does not interfere with the release
valve and handle socket operation.
2. A rubber handle holder
3. A 2-piece handle

• Assemble the handle sections by lining up
the spring detent in the rubber grip section
with the slot in the other section.

(refer to Fig. 3, page 4)
RAISING THE JACK
• Compare these illustrations with your jack
BEFORE operation and/or oil level
maintenance to become familiar with the
location of various jack components.
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.
BEFORE USE
Occasionally during shipment and/or
handling, air gets trapped in the hydraulic
system, which interferes with jack
performance. To release this trapped air do
the following:
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.
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.
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.
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. 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.
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. Immediately after lifting, transfer the load
to a pair of appropriately rated jack stands.
Rated capacity of jack stands is per
!
4. Ensure that the pump operates smoothly
before putting into service. Lubricate as
instructed in the Maintenance Section (see
page 7).
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.
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.
• When the ram reaches maximum
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.

high enough to reinstall jack stands.
!
b. Remove the affected jack and then the
stands.
c. Using the other jack, lower the load by
turning the operating handle counter-
clockwise, but no more than 1/2 full
turn.
1. Raise load high enough to clear the jack
stands, then carefully remove jack stands
(always use in pairs).
2. Slowly turn the handle counterclockwise,
but no more than 1/2 full turn. If the load
fails to lower:
3. After removing jack from under the load,
push saddle down to reduce ram exposure
to rust and contamination.

hole. DO NOT allow dirt or other foreign
material to enter the hydraulic system when
filling.
Important: When adding or replacing oil,
ALWAYS use a good grade Hydraulic Jack
oil. DO NOT use Hydraulic Brake Fluid,
Alcohol. Glycerine, Detergent, Motor Oil or
dirty oil. Use of an improper fluid can cause
serious internal damage to your jack.
• After refilling, remove any air from the
hydraulic system by opening the release
valve and rapidly pumping the jack handle
several times.
• Replace the oil filler plug.
ADDING OIL
• Position the jack on level ground in an
upright (vertical) position and fully lower the
saddle.
LUBRICATION
• Add lubricating oil to all moving parts as
needed.
• Remove oil filler plug (see Fig. 3).
• Oil should be filled to the level of the oil
filler plug hole. If low, add oil as needed.
PREVENTING RUST
• Check ram and pump plunger (see Fig. 3)
every few months for any signs of rust or
corrosion. Clean as needed by wiping with
an oily cloth.
REPLACING OIL
• To drain oil, remove oil filler plug and open
release valve (see Fig. 3).
• When not in use, ALWAYS store jack with
saddle and pump plunger lowered all the
way down.
• Turn jack on its side and drain old oil out
through the oil filler plug hole.
STORAGE
HOW TO STORE YOUR JACK
This jack is designed for compact and convenient storage (see Fig. 5).
• Insert the rubber handle holder onto the top nut.
• Depress the spring lock to separate the handle pieces, and insert them into the handle
holder.
