COATS 950 Pro Racer Wheel Balancer - Manual (Page 19)

Maintenance and Calibration
Preventative Maintenance
The balancer requires only minor maintenance to keep the unit
operating properly.
1. Keep the display clean and clear. Use a vaporizing cleaner
only. Do not use cleaners or solvents, which leave oily or filmy
residues behind.
2. Keep the adapters, cones, faceplate, threaded arbor, pressure
cup, and hub nut clean. Grease and dirt buildup will cause prema-
ture wear and inaccurate balancing. Clean at least once a day with
a vaporizing solvent.
3. Clean the weight tray, accessory post, and pegs. Weights
stored in a dirty tray will pick up grease and dirt which may alter
their weight or keep them from securely attaching to the wheel.
Use a vaporizing solvent to clean the tray, pegs, and post.
4. Keep the area around the balancer clear. Remove any tools or
other items that are leaning against the balancer. Keep the area
under the balancer clear as well. Remove any items that may
cause the balancer to not sit level.
5. Use only COATS accessories. Accessories from other manu-
factures may not fit or function properly, and may damage the bal-
ancer.
Calibration
The balancer utilizes a “self calibration” scheme. To keep your bal-
ancer in proper calibration, this calibration procedure should be
performed once a month, or whenever the accuracy of the bal-
ancer is questioned.
1. Mount a 185 x 14 or 195 x 14 tire/wheel assembly on the bal-
ancer.
2. Enter A, W, and D wheel measurements.
NOTE: An entry must be between 5.0 and 8.0, and W entry must
be between 5.5 and 7.0. If the wheel you have mounted does not
meet these requirements, select a different wheel and try again.
3. Remove any weights attached to the wheel.
4. Press and hold SHIFT and press 1.
5. Press START.
6. Rotate the wheel until the outer weight positioning LED
flashes, and attach a 4 ounce weight (100 grams) at top-dead-cen-
ter.
NOTE: It is critical that this weight be placed accurately to
achieve proper calibration.
7. Press START.
8. Remove the weight.
The balancer is now calibrated. If a mistake is made during this
procedure, turn the balancer off, then back on, and start the pro-
cedure over again.
