Demounting & Mounting
•
Always clean and inspect the wheel prior to any service.
•
Never stand on the frame or work table while demounting or mounting a tire.
•
Always keep hands, feet, and other objects away from moving parts while the machine is turned on.
•
Always place the narrow bead seat to the outside when clamping. Failure to demount the tire from the narrow bead seat
side may cause damage to the tire beads.
•
Always apply an approved rubber lubricant to rim flanges and both tire beads before demounting or mounting and
seating the beads.
•
Never mount a tire on a damaged or rusty wheel as tire or wheel failure may result during inflation. Explosion from
failure may result in severe injury or death of the operator and bystanders.
Inflation
•
Always be sure the bead opposite the tool is in the drop center before rotating the tire when demounting or mounting to
avoid damage to the tire beads.
•
Always follow all applicable Local, State, and Federal Codes, Rules, and Regulations; such as the Federal OSHA
Standard Number 1910.177.
•
Always use an approved inflation chamber or inflation cage equipped with a self-gripping chuck and remote inflation
gauge and valve.
•
Always inflate the tire to manufacturer’s recommended cold operating pressure.
•
DO NOT OVER INFLATE! Tire or wheel failure during and after inflation may result in an explosion capable of causing
severe injury or death.
•
Never reinflate a tire that has been run under inflated or flat without first demounting the tire and checking for wheel
and tire damage.
•
Always inspect the tire interior for loose or broken cords, cuts, penetrating objects, and other damage. Discard tires that
cannot be properly repaired.
•
Never rework, weld, heat or braze wheels.
•
Never strike the tire or wheel with a hammer.
•
Always be sure the tire diameter exactly matches the wheel diameter.
Danger!
Tire failure under pressure can be hazardous. When possible, always place wheels inside an approved inflation chamber or cage
before inflating. Use an approved remote inflation valve, hose, and gauge. Always wear safety goggles for eye protection. Do
not stand beside the wheel or cage during inflation. Keep hands and other parts of the body out of the cage during inflation.
Observe the tire pressure frequently. Do not exceed the manufacturer’s recommended maximum inflation pressure. Failure to
follow these instructions may cause the tire and rim to separate with tremendous force, resulting in serious personal injury or
death.
