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 qualied 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
other than hard level surfaces, and using equipment for a purpose
for which it was not designed.
It is the responsibility of the owner to make sure all personnel read
this manual prior to using this device. It is also the responsibility of
the device owner to keep this manual intact and in a convenient
location for all to see and read. If the manual is lost or not legible,
contactNorcoIndustries, Inc. for afreereplacement. If the operator
is not uent in English, the product and safety instructions shall be
read to and discussed with the operator in the operator’s native
language by the purchaser/ owner or his designee, making sure
that the operator comprehends its contents.

Before supporting the vehicle component with this jack refer• to the vehicle’s service manual or inquire from the vehicle
manufacturer the recommended under hoist jack support
surface(s) on the vehicle component.
Be sure vehicle, vehicle component and under hoist jack setup• are stable.
Use only on a hard level surface.•
SETUP
The bottom of the lifting tube includes a hex head bolt which1.
must be backed off so the minor diameter of the jack ram can slide
into the bottom of the lifting tube. Place the round jack base at
on the oor. Slide the lifting tube over the ram and secure them in
place by tightening the hex head bolt.
Adetent pin is connected to the top of the lifting column by way2.
of a wire lanyard. Install the detent pin in the hole on the telescopic
saddle tube closest to the saddle. Allow the exposed ends of the
detent pin to rest on the lifting tube.
Sometimes air gets trapped in the hydraulic system during 3.
shipment. An air bound hydraulic system feels spongy when
pumped and sometimes the jack will not pump in full incremental
strokes.
PURGING AIR FROM THE HYDRAULIC SYSTEM
The release valve is activated by stepping on the foota.
treadle. Stepping on the right of the treadle closes the
release valve for pumping and stepping on the left of the
treadle opens the release valve for lowering the load. Step
on the left of the treadle while simultaneously using one
hand to pump the foot pedal about ten full strokes.
Release your foot from the foot treadle and pump the jackb. until the ram is extended to maximum height.
If the condition remains, repeat steps “a” and “b” until all thec. air is purged from the system.
Note: Revision letters (A, B, C, D etc.) after model numbers have been omitted as they do not affect the setup,
operating and maintenance instructions of a particular jack unless otherwise noted.
