Maintenance Instructions
WARNING
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.
CAUTION
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.
The balancer requires only minor maintenance to keep
the unit operating properly.
1. Keep the touchscreen clean and clear. Use the
screen wipes (part # 85609548) included with your
Vero Series™ wheel balancer to clean the unit’s touch-
screen. Use of these or similar screen wipes, or a
clean soft damp cloth are the only safe and acceptable
methods to clean the unit’s touchscreen. Do not use
cleaners or solvents which leave oily or filmy residues
behind that will void the touchscreen’s factory warranty.
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 studs, pegs,
or storage shelves with a mild detergent. 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.
Diagnostic Procedures
After Balance Vibration Problems
If vibration is still present after balancing the wheels
and driving the vehicle on smooth pavement, remove
the wheels and recheck the balance. If a wheel is out
of balance the cause maybe:
• Wheel was not mounted/centered correctly on the
balancer.
• A weight has come off the wheel (possibly the
wrong clip style). Remove the other weights from
the wheel and rebalance.
• Foreign material inside the tire. Remove the tire
from the wheel, remove the foreign material, and
remount. Remove wheel weights and rebalance the
wheel.
• Stones or other foreign objects caught in the tire
tread or rim. Remove the objects. Check and rebal-
ance if needed.
If the balancer still indicates the wheels are balanced
to within 0.05 ounces (1.42 grams) on both inner and
outer displays, the problem is not in the balance of
the wheels. Check the following possible sources of
vibration:
• Tire pressure. Bring all tires up to the recommended
PSI.
• Radial or lateral runout in the tire or wheel. Replace
the damaged part.
• Out of balance in wheel covers or trim rings.
Remove the wheel covers or trim rings and test
drive. If the vibration is gone, remove the shaft and
use an appropriate adapter to mount the wheel to
the balancer. Balance the wheel with the wheel
cover or trim ring attached to the wheel.
• Incorrectly mounted tire and wheel. Remount cor-
rectly.
• Damaged wheel bolt holes. Replace wheel.
• Worn universal joints. Replace as required.
• Drive shaft out of balance or damaged. Balance,
repair, or replace.
• Out of balance in brake rotor(s) or drum(s).
• Suspension out of alignment. Align the vehicle and
replace any damaged or worn parts.
