OPERATION
WARNING! Additional - Mechanical Jack Operating Practices
The rated load of the mechanical jack shall not be exceeded.
WARNING!
• Do not use this jack on curved or tubular vehicle bumpers. The vehicle could slip off the jack and fall,
causing serious injury or death. Do not raise inflated tire more than 2" above the ground. Never attempt to
lift more than one wheel at a time.
• The working load of each chain or tow strap must be greater than the strength of the jack. If a chain or tow
strap breaks while winching, the load could shift or the chain or tow strap could snap back. When used as a
winch, the top clamp will support up to 3307 lbs. (1500 kg). If you go over this limit, the top clamp could
bend or break, causing the load to shift or the chain or tow strap to snap back. If that occurs, it could result
in damage or injury.
• The maximum clamping force is 750 lbs. (340 kg). If you exceed this limit, the top clamp could bend or
break, resulting in injury or damage.
DANGER: Do not use the jack to support a load. Securely chock and block (stabilize) the load to be lifted.
Never get under a raised load without properly chocking and supporting the load. If a raised load falls it
can cause serious injury or death. Always place the handle against the steel standard (bar) before moving
the reversing latch. This will prevent the handle from moving up and down rapidly, which could cause
serious injury or death if it comes into contact with any part of your body. Always keep your head out of the
travel path of the handle.
• THIS JACK WILL NOT STABILIZE THE LOAD. You must chock and block (stabilize) the load to prevent it
from moving or falling. If a raised load falls, it can cause serious injury or death. Lowering the load can be
dangerous. Keep your head clear of the path of the handle. During lowering, the weight of the load pushes
up against the jack's handle. 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. If your head is in the handle's travel path, it could strike
you, causing serious injury or death.
• Do not use the jack to support a load. Securely chock and block (stabilize) the load to be lifted.
Never get under a raised load without properly chocking and supporting the load. If a raised load falls it can
cause serious injury or death.
• Never work under raised equipment unless additional supports are used under the lifted
equipment.
CHOCK AND BLOCK (STABILIZE)
A chock is a wedge for steadying a body and holding it motionless, or for preventing the movement of a wheel.
When you block a load, you secure and support a load that is being lifted. The block(s) or stabilizer(s) should
have a weight capacity that is greater than the weight of the load which is being lifted.
