1. Safety Regulations
1.1 Warnings
Failure to follow all of these safety instructions can
lead to severe injury or death from a sudden loss of
the load. Contact the manufacturer at the numbers or
address printed on the back cover of this manual if
you have any questions.
Use the jack to raise one end of a vehicle or trailer.
This jack is designed to for lifting only one end of the
vehicle or trailer, not supporting. Once the vehicle or
trailer is lifted, place vehicle supports stands under
the vehicle or trailer and remove the jack from the
work area. Using this jack to raise loads other than at
the end of the vehicle or trailer can result in serious
injury or death. NEVER use the jack on a vehicle while
the motor is running.
Anyone who operates this jack must read and
understand all the instructions and warnings
provided with this jack before being allowed to use
it. All operators must be careful, competent, trained,
and qualified in the safe operation of the jack. The
owner (or other responsible individual) must ensure
that any operator observes the proper safety
procedures for using this jack at all times. If the
operator does not read well or is not fluent in English,
the owner / manager must read and review the
instructions and warnings in the manual with the
operator in the operator's native language to be sure
that the operator will use the jack properly.
The owner / manager must keep this manual for
future reference, and make sure the warning labels
on the jack are legible and intact at all times.
Replacement labels and manuals are available from
the manufacturer. Call the manufacturer using the
contact information on the back cover of this manual
if you have any questions.
If there is any evidence of hydraulic oil leaking
from underneath this lift, the lift must be removed
from service and returned to the manufacturer for
servicing. Contact the manufacturer as soon as
possible. If this warning is not heeded, it may result in
possible serious injury and/or property damage or
death.
NEVER use this jack in conjunction with any other
jack or lift. NEVER use a jack to raise one side of a
vehicle.
ONLY use the approved manufacturer’s
recommended lifting points on vehicles and trailers.
NEVER overload this jack. The jack’s maximum
capacity is 20,000 lbs. / 9070 kg. If you need to lift
more than this, use a jack that has a higher maximum
capacity.
NEVER modify the jack in any way. Modifications
may cause the jack to perform improperly, resulting in
injury or death. NEVER use the jack with aftermarket
accessories, lift pads, or adaptors, not supplied by
the manufacturer.
NEVER loosen the hex nut on top of this jack. This
nut, if loosened will cause the jack to leak air and not
function properly.
NEVER abuse or cause damage to the jack. NEVER
subject the jack to abnormal shocks or loads. Your
safety and that of others depends on the proper
operation of the jack.
When raising the load, chock the wheels on the
end opposite the jack. Place the jack into position,
put vehicle in neutral, and disengage the parking
brake. These steps must be taken before connecting
the air supply to the jack.
