Operator Protective Equipment
Personal protective equipment helps make tire ser-

place of safe operating practices. Always wear durable
work clothing during tire service activity. Loose fitting Watch for this symbol! It means BE ALERT! Your
clothing should be avoided. Tight fitting leather gloves safety, or the safety of others, is involved!
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.

Two weight display windows, one Inboard and one Outboard, are positioned above the Wheel Cross-section
Diagram. After a wheel measurement cycle, the balancer calculates the corrective weight amount and indicates
it in the appropriate display window. All weight readings are shown in Ounces or Grams. Also displays A, W,
and D values, functions, and instructions for the operator. Error messages will also be shown in this display.
The Total Static window indicates the value of the total static unbalance. See MATCH BALANCE (Optimiza-

 Maintenance Instructions

Use caution, 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 electrocu-
tion 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 elec-
tronic components, wiring harnesses, and
other devices housed in the balancer are
not intended to be exposed to water.
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.
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 cautious 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.
Important: Always be sure to remove the wheel
assembly from the pneumatic shaft before disconnect-
ing the air supply from the machine.

Important: Always read and follow instructions. • 19

Overload Protection - The balancer’s motor is over-

utes the machine automatically resets itself; activating
the fan motor. If this happens, notify your Certified
Service Partner immediately.
Important: Allow the fan to cool the motor for at least
30 minutes before using the balancer so the overload
