Maintenance Instructions
The balancer requires only minor maintenance to
keep the unit operating properly.
1. Keep the display clean and clear. Use a damp
cloth. Do not use cleaners or solvents which leave oily
or filmy residues behind.
2. Keep the adapters, cones, faceplate, threaded
shaft, pressure cup, and hub nut clean. Grease and dirt
buildup will cause inaccurate balancing and premature
wear. Clean these items at least once a day with a
vaporizing solvent.
3. Clean weight tray and any accessory posts, pegs,
or storage shelves with a vaporizing solvent. Weights
stored in a dirty tray may pick up grease and dirt which
may keep them from securely attaching to the wheel.
Use common sense, this is an electrical
device. Exposing the balancer to water,
either by hose or bucket, or by exposure to
rain or snow, may cause risk of shock or
electrocution to operator or bystanders.
Place, store, and operate the balancer only
in a dry, sheltered location.
Do not hose down with water or bucket
wash the balancer. Extensive damage to the
balancer will result. Sensitive electronic
components, wiring harnesses, and other
devices housed in the balancer are not
intended to be exposed to water.
4. Keep the area around and under the balancer
clear. Remove any tools or other items that are leaning
against the balancer. Remove any items that may
cause the balancer to not sit level. Be particularly cau-
tious of new or used wheel weights on the floor, as
they may cause personal injury due to falls.
5. Use only COATS ® accessories. Accessories from
other manufacturers may not fit or function properly,
and may damage the balancer.
6. To replace Arm Laser battery, remove cover (fig.
23). Discard old battery. Install a new battery and
replace the cover.
