7. 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 Compressed air supply
The jack requires a supply of compressed air to
operate.
To Operate a Single Jack
If the jack is being used as a single jack, the following
steps need to be completed prior to use:
1. Connect a quick coupler to the air control valve.
2. Attach an air hose with 200 psi maximum to the quick
coupler. The unit is now ready for use.
3. Actuate the air control valve lever and check that the
lift post raises and lowers as expected.
To Operate a Pair of Jacks
Because these jacks are often used in pairs, operating
the air control valves on both jacks simultaneously from
one airline offers advantages. To utilize a single airline,
assemble the air control valve from each jack according
to the Figure below or contact the manufacturer to
purchase a "Valve Tee Connection" kit (#8855-01009):

7.2 Preparation before operation
1. Make sure the vehicle load does not exceed the rated
capacity of the jack (see Specifications for the jack
model purchased).
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. 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.
NEVER attempt to lift from a polished or greasy 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.
5. 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.
6. Verify that the vehicle's engine is not running before
raising it.
