Operation Instructions
Raising a Stationary Load
DO NOT USE THE JACK TO SUPPORT OR STABILIZE A LOAD. Using the jack to support or
stabilize a load may result in unexpected movement and result in serious injury, being crushed
and death. Always securely chock and block (stabilize) the load to be lifted. Never place any
part of the body under a raised load without properly chocking and supporting the load.
Using the jack on curved or tubular vehicle bumpers will result in the vehicle slipping off the
jack and falling, causing serious injury or death. Use the Bumper Lift or Lift-Mate to lift most
vehicles with curved bumpers or plastic bumpers.
Unexpected movement of the jack handle may result in the user being struck causing serious
injury or death. Always keep your head away from and out of the jack handle path of move-
ment.
The jack handle may move rapidly when moving the reversing latch and cause serious injury
or death. Always place the handle against the steel standard bar with the handle clip spring
holding it up before moving the reversing latch. This will prevent the handle from moving up
and down rapidly. Securely hold on to the jack handle so your hands do not slip and ensure the
handle is not in the horizontal position when moving the reversing latch.
Important! During lifting and lowering, the weight of the load pushes
up
against the jack’s han-
dle. If your hands slip off the handle, or if the handle is horizontal when you move the reversing
latch, it may move up very quickly.
Raising an inated tire more than 2” (5cm) above the ground or attempting to lift more than
one wheel at a time may result in tip over, unexpected movement and serious injury or death.
Always raise an inated tire less than 2” (5cm) and only one tire at a time.
Handle force required to raise 4,660 lbs. is 177 lbs. at 34” on the handle. Maximum rated load
is 4,660 lbs. (2273 kg) up to 48” (121 cm), tested to 7,000 lbs. (3175 kg). Upper 12” of 60”
jack is rated to 2,660 lbs. (1209 kg) only, tested to 4,000 lbs. (1818 kg).
If you overload the jack during operation, the shear bolt will break. If the shear bolt breaks, as it
will at 7,000 lbs. (3175 kg), the load should be supported, but the jack’s handle will drop freely.
Use a jack with a larger load capacity to lower the load safely to the ground. Do not replace the
shear bolt with a bolt of greater strength as this could cause the jack to fail and drop the load.
Always use a shear bolt supplied by Hi-Lift Jack Company. Do not replace the shear bolt while
the jack is under load.
