OPERATION
, This Jack Is a Lifting Device Only •
Designed only for lifting part of the total
vehicle (ie. one wheel). Do not move or dolly
thevehicle while it ison the jack.
•Position the Jack •
Position this jack to only lift on the areas of
the vehicle specified by the vehicle
manufacturer.
• Use Support Stands •
After lifting the vehicle always support the
load with appropriately rated vehiclesupport
stands before workingon the vehicle.
• Do Not Overload Jack •
Do not overload this jack beyond its rated
capacity. Overloading can cause damage
toor failure of thejack.
• Use on Hard Level Surfaces •
This jack is designed only for use on hard
level surfaces capable of sustaining the
load. Use on other than hard level surfaces
can result in jack instability and possible
loss of load.
• Center Load on Jack Saddle •
Center load on jack saddle before lifting
vehicle. Off-center loads and loads lifted
when the jack is not level can cause loss of
load or damage to the jack.
Read Operating Instructions •
Study, understand and follow all
ins_'uctions in this manual before operating
the jack. Failure to heed these warnings
may result in loss of load, damage to the
jack and/or jack failure resulting in _ersonal
injury or property damage.
During shipment and handling, air may get
trapped in the hydraulic system, which can
interfere with the jack's lifting performance.
Follow these steps to release air from the
hydraulic system:
• Open the release valve by turning the jack
handle counter clockwise (Fig. 1).
• Loosen oil filler plug (Fig. 1).
• Rapidly pump jack handle with several full
strokes.

Operation
Raising the Jack
.Close the release valve by turning the handle
clockwise.
•Block the vehicles wheels for lifting stability.
•Refer to the vehicle manufacturer owners
manual to locate approved lifting points on the
vehicle. Position the jack so that the saddle is
centered under the load at an appropriate lift
point.
•Pump jack handle until saddle nears contact
with the vehicle. Check to see that the saddle
is centered and will contact the load lifting point
firmly.
• Continue to pump the jack handle to lift the
vehicle to the desired height. After lifting,
support the load with appropriately rated
vehicle support stands before working on the
vehicle.
Lowering the Jack
• Open the release valve very slowlyby turning
the handle counter-clockwise.
With 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.'This raises the saddle.
• When the ram reaches maximum extension,
oil is bypassed back into the reservoir to
prevent an over extended 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.
