IMPORTANT SAFETY INSTRUCTIONS

READ ALL INSTRUCTIONS

1.Eye and face protection recommendations:

“ Protective eye and face equipment is required to be used where there is a reasonable probability of injury that can be prevented by the use of such equipment.” O.S.H.A. 1910.133(a) Protective goggles, safety glasses, or a face shield must be provided by the owner and worn by the operator of the equipment. Care should be taken to see that all eye and face safety precautions are followed by the operator. ALWAYS WEAR SAFETY GLASSES. Everyday glasses only have impact resistant lenses, they are not safety glasses.

2.Do not disable hood safety interlock system, or in any way shortcut safety controls and operations.

3.Be sure that wheels are mounted properly, the hub nut engages the arbor for not less than four (4) turns, and the hub nut is firmly tightened before spinning the wheel.

4.Read and understand this manual before operating. Abuse and misuse will shorten the functional life.

5.Be sure the balancer is properly connected to the power supply and electrically grounded.

6.Do not operate equipment with a damaged cord or if the equipment has been dropped or damaged – until it has been examined and repaired by a qualified serviceman.

7.Do not let cord hang over edge of table, bench, or counter or come in contact with hot manifolds or moving fan blades.

8.If an extension cord is necessary, a cord with a current rating equal to or more than that of the equipment should be used. Cords rated for less current than the equipment may overheat. Care should be taken to arrange the cord so that it will not be tripped over or pulled.

9.Keep guards and safety features in place and in working order.

10.Wear proper clothing. Safety toe, non-slip footwear and protective hair covering to contain hair is recommended. Do not wear jewelry, loose clothing, neckties, or gloves when operating the balancer.

11.Keep work area clean and well lighted. Cluttered and/or dark areas invite accidents.

12.Avoid dangerous environments. Do not use power tools or electrical equipment in damp or wet locations, or expose them to rain.

13.Avoid unintentional starting. Be sure the balancer is turned off and power disconnected before servicing.

14.Disconnect the balancer before servicing.

15.Use only manufacturer’ s recommended accessories. Improper accessories may result in personal injury or property damage.

Safety

Owner’ s Responsibility

To maintain machine and user safety, the responsibility of the owner is to read and follow these instructions:

•Follow all installation instructions.

•Make sure installation conforms to all applicable Local, State, and Federal Codes, Rules, and Regulations; such as State and Federal OSHA Regulations and Electrical Codes.

•Carefully check the unit for correct initial function.

•Read and follow the safety instructions. Keep them readily available for machine operators.

•Make certain all operators are properly trained, know how to safely and correctly operate the unit, and are properly supervised.

•Allow unit operation only with all parts in place and operating safely.

•Carefully inspect the unit on a regular basis and perform all maintenance as required.

•Service and maintain the unit only with authorized or approved replacement parts.

•Keep all instructions permanently with the unit and all decals/labels/notices on the unit clean and visible.

•Do not override safety features.

Operator Protective Equipment

Personal protective equipment helps make tire servicing safer. However, equipment does not take the place of safe operating practices. Always wear durable work clothing during tire service activity. Loose fitting clothing should be avoided. Tight fitting leather gloves are recommended to protect operator’ s hands when handling worn tires and wheels. Sturdy leather work shoes with steel toes and oil resistant soles should be used by tire service personnel to help prevent injury in typical shop activities. Eye protection is essential during tire service activity. Safety glasses with side shields, goggles, or face shields are acceptable. Back belts provide support during lifting activities and are also helpful in providing operator protection. Consideration should also be given to the use of hearing protection if tire service activity is performed in an enclosed area, or if noise levels are high.

¨Balancing Your First Tire

1. Turn the machine OFF then ON (resets machine).

Note: The machine wakes up using standard clipon wheel weight locations (Clip 1 & Clip 2) and wheel dimensions.

2.Mount a tire/wheel on the balancer that will use standard clip-on wheel weights.

Use the most appropriate mounting method.

3.Always remove any weights already attached to the wheel.

4.Enter A & D wheel dimensions

using offset arm.

For Automatic Measurement —pull offset arm out to the wheel, hold it still at clip-on weight position against wheel flange, and wait for BEEP. Return arm to home position.

Clip-on Weight Location —viewed on a cut-away rim for clarification.

8. Inboard center bar blinks.

Note: If an inboard corrective weight is not required, the wheel will stop at the outboard corrective weight location, goto step 11.

9. Attach inboard corrective weight.

Attach specified weight amount at top-dead- center on inside flange of wheel.

10.Press NEXT; wheel rotates.

11.Outboard center bar blinks.

12.Attach outboard corrective

weight.

Attach specified weight amount at top-dead- center on outside flange of wheel.

13.Lower the hood to respin the tire/wheel and check balance.

The weight readings should now be 0.00.

Note: Throughout this manual tire dimensions are referred to as A, W, and D, see figure 2.
