Operation
WARNING
- This section discusses the appropriate and
safe methods for using the jack to raise and lower a
vehicle. Safe operation is not limited to simply raising
and lowering a vehicle - it also includes adequate
preparation before the vehicle is lifted. Failure to follow
all of the steps outlined in this section could result in
serious injury or death.
7.1
Preparing to lift
1.
Make sure the load does not exceed the rated capacity
of the jack (20,000 lbs. / 9,070 kg.)
2.
Inspect the jack for signs of wear or damage (see
“Inspection Instructions” in Section 8). The jack should
be immediately removed from service if you detect any
abnormal conditions or signs of damage that suggest
the jack will not work properly or safely — When in
doubt, don’t use the jack!
If you see any signs of wear or damage, or if there is any
indication that the jack is not performing normally,
immediately take it out of service and contact customer
service at the address and number shown on the back
cover of this manual. NEVER use a jack that appears
damaged in any way.
3.
Transport the jack to the work area by wheeling it. You
can push or pull the jack. Wheel the jack across smooth
surfaces only.
Jolting caused by the wheels catching on uneven
surfaces can cause physical strain and personal injury.
4.
Select appropriate vehicle support stands and bring them
to the immediate work area. Follow the instructions
supplied with the vehicle stands. Use appropriate vehicle
stands to support the load immediately after lifting.
NEVER use the jack to support a load while working on a
vehicle. Failure to follow all of these instructions can result
in jack instability and loss of a load.
5.
Examine the work area. Use the jack only on hard, level
surfaces capable of safely supporting the load. The jack
must ALWAYS remain in direct contact with the floor.
Clear the surrounding area of personnel, tools,
equipment, or any other objects that would interfere with
the use of the jack. If these conditions cannot be met,
move the vehicle and jack to an area where the lift can be
performed safely.
6.
Chock the vehicle’s wheels. When raising a vehicle from
one end, always chock the wheels that will remain on
the ground. Make sure at least two wheels of the vehicle
remain in contact with the floor at all times — NEVER
use the jack to raise all four wheels of the vehicle from
the floor.
7.2
Operating the air valve to raise a load
Once the lift has been positioned under the load to be
lifted (according to the safety instructions on the lift),
operate the air valve slowly to carefully raise the saddles
to engage (capture) the lift points of the vehicle (Fig. 3).
After the saddles make contact with the lift points,
visually recheck their position to be sure the load is
properly seated for lifting. Be careful not to put any part
of your body (e.g., arms, hands, fingers, etc.) between
the saddle and the lift point on the vehicle. When raising
or lowering, the operator should check to make sure
nobody else is in the immediate work area.
Fig. 3: Air valve operation
To lower the lift, it may be necessary to raise the lift slightly
so the down stop pawl can be disengaged from the down
stop lug. If lowering the vehicle on vehicle support stands,
follow the instructions for positioning and supporting the
load outlined in the stand instructions. If lowering the load
to the ground, make sure that the work area underneath
the vehicle is clear of obstructions before removing the
vehicle support stands. Disengage the down stop pawl by
holding the lever while pressing the air valve to the right
(i.e., the lower position). Hold in the air valve and down stop
lever until the lift can be removed from under the vehicle.
Air must bleed off for a few seconds before the lift will start
lowering.
To avoid a crushing injury, you must make sure that no
objects or body parts are on the ground near the lift
platform whenever the lift and/or the load are being
lowered.

instructions

instructions provided on the lift itself.
