WARNING
A
• This Jack is a Lifting Device Oniy •
Designed only for lifting part of the total
vehicle (ie. one wheel). Do not move or dolly
the vehicle while it is on 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 vehicle support
stands before working on the vehicle.
• Do Not Overload Jack •
Do not overload this jack beyond its rated
capacity. Overloading can cause damage
to or failure of the jack.
Use on Hard Level Surfaces •
This jack is designed only for use on hard
evel surfaces capable of sustaining the
load. Use on other than hard level surfaces
can result in jack instability and possible
OSS 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
instructions in this manual before operating
the jack. Failure to heed these warnings
may result in loss of load, damage to the
ack and/or jack failure resulting in personal
injury or property damage.
A
CAUTION
A
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.
Keep Hands and Feet Clear of the Jack
Hinge Mechanism and Ground Contact
Area When Lowering the Load!
• Close the release valve by turning the handie
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 slowly by 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. Hydrauiic 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.
