PERSONAL INJURY AND/OR PROPERTY DAMAGE.
The use of portable automotive lifting devices is subject to certain
hazards that cannot be prevented by mechanical means, but
only by the exercise of intelligence, care, and common sense. It
is therefore essential to have owners and personnel involved in
the use and operation of equipment who are careful, competent,
trained, and qualified in the safe operation of the equipment and
its proper use. Examples of hazards are dropping, tipping, or
slipping of motor vehicles or their components caused primarily by
improperly securing loads, overloading, off-centered loads, use on
• Before lifting a vehicle, refer to the vehicle's service manual or
inquire from the vehicle manufacturer the recommended jack
lifting points and jack stand support surfaces on the vehicle
chassis.
• Inspect the jack before each use. Do not use the jack if it is
damaged, altered, modified, in poor condition, leaking hydraulic
fluid, or unstable due to loose hardware. Take corrective action
before using the jack.
• This jack was designed for lifting purposes only. Do not attempt to
work on the vehicle until jack stands rated equal to or greater than
the rated capacity of the jack are positioned to support the load.
1. Remove the handle receiver bolt from the handle receiver. Insert
the "T" handle in the handle receiver so that the "L" slotted hole in
the handle aligns with the threaded bolt hole in the handle receiver.
The handle receiver bolt has a non-threaded tip which must enter
the "L" slotted hole in the handle. Sometimes it is necessary to
rotate the handle back and forth while simultaneously threading
the handle receiver bolt into the "L" slotted hole. You can feel when
the bolt enters the "L" slotted hole.
2. Attach the air line from the handle to the air line coming from
the jack with the quick disconnect provided.
3. Sometimes air gets trapped in the hydraulic system during
shipment. An air bound hydraulic system feels spongy when
pumped and sometimes the jack will not pump full incremental
strokes.
