åBe aware of all power lines, electrical circuits, water pipes and other mechanical hazards in
your work area, particularly those hazards below the work surface hidden from the operator’s
view that may be unintentionally contacted and may cause personal harm or property damage.
åBe alert of your surroundings. Using jacks in confined work areas may put you dangerously
close to cutting tools and rotating parts.
PERSONAL SAFETY
åStay alert, watch what you are doing and use common sense when operating this jack. Do not
use a tool while you are tired or under the influence of drugs, alcohol or medication. A moment
of inattention while operating tools may result in serious personal injury.
åDress properly. Do not wear loose clothing, dangling objects, or jewelry. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught
in moving parts.
åUse safety apparel and equipment. Use safety goggles or safety glasses with side shields
which comply with current national standards, or when needed, a face shield. This applies to all
persons in the work area. Also use non-skid safety shoes, hardhat, gloves, dust collection
systems, and hearing protection when appropriate.
åDo not overreach. Keep proper footing and balance at all times.
TOOL USE AND CARE
åRead all the instructions and warnings first before attempting to operate this jack.
åDO NOT operate jack on inclined surfaces. Jack must be used on level surfaces only.
Unanticipated motion can occur as soon as jack lifts tire from surface.
åDO NOT overload jack beyond the load rating (1500 lbs. per unit)
åDO NOT start the vehicle’s engine, or drive a vehicle while the jack is in use. Jacks are
designed for hand maneuvering of vehicles only.
åDO NOT use jack to lift tires wider than 9 inches.
åDO NOT attempt to push jack over obstacles. Jack is designed to be used on level and smooth
surfaces only.
åAfter lifting, be sure to always lock the pin in place before operating. Pull the pin out after

OPERATION
1. Place jack on floor and press down on the pedal to release pedal lock. Pull out the lock pin
from frame.
2. Before operation, open release valve by turning the hand-wheel counterclockwise. Expand
the jack with the hand-wheel to place the rollers around the tire; position the jack so both

rollers are in contact with the tire tread. To obtain the best control of the jack while
expanding the rollers around the tire, place your left hand on top of the left side axle and
place your right hand at the center of the pedal. Close the release valve by turning the
hand-wheel clockwise to a snug-tight position; jack may now be used.
3. Install jack so that the unit is parallel to the sidewall of the tire to be lifted. Leave
approximately 3/4" of clearance between tire and jack. This is very important. If unit is
misaligned, the tire may hit the axle of the jack and not the rollers; this may damage the
jack and void the warranty.
4. To lift tire, flip the directional lever up, then place foot on pedal, depressing the pedal with
smooth, even strokes. Cycle pedal until tire is lifted from surface one inch or less. After
lifting, the lower the tire is to the ground the more stable jack will be. After lifting, be sure
to always lock the pin in place before operation. If using more than one jack, repeat
process on the other tires and maneuver the vehicles as required.
5. To release jack, pull the pin out from the frame and open the valve by turning the
hand-wheel counterclockwise slowly. Jack may be removed when rollers disengage from
the tire.
MAINTENANCE
åMaintain your jack. It is recommended that the general condition of any jack be examined
before it is used. Keep your jack in good repair by adopting a program of conscientious
repair and maintenance. Have necessary repairs made by qualified service personnel.
åCleaning. Use only soap and a damp cloth to clean your tools. Many household cleaners
are harmful to plastics and other insulation.
