COATS 700 Solid State Wheel Balancer - Manual (Page 12)

Maintenance and Service
Do not use solvents, which
leave an oily residue.
Never use compressed air
or a water hose to clean
any part of your balancer.
Preventative Maintenance
Daily
Clean shaft and faceplate with a vaporizing
solvent. Cones, hub nut, and other
mounting hardware should be checked and
cleaned.
Weekly Thoroughly clean entire unit. Remove all
used weights, tools, and parts from under
and around balancer. Perform a calibration
check. Make calibration adjustments if
required.
ATTENTION: Maximum duty cycle is 40 wheels per
hours at 56 pounds.
NOTE: Before each balancing operation, make sure
that the back face of the wheel is clean. Use a wire
brush to clean the back face of the wheel if needed.
Service
If service should ever be required for your balancer,
contact the Service Department at (800) 688-6359.
Have your model and serial number ready.
Calibration Check Procedure
This procedure can be performed by the operator to
ensure the balancer is operating correctly and
properly calibrated. The only purpose of calibration is
to fine-tune the balancer to yield single-spin
balancing.
Use the fine balance mode during this procedure
(press and hold SHIFT and press ROUND OFF).
If the balancer fails to produce the results outlined in
this procedure, perform a calibration adjustment.
1. Use normal mounting procedures to mount a
standard domestic 14, 15, or 16-inch diameter x
6 to 6-1/2-inch wide steel wheel with standard
tire mounted and properly inflated. Do not use a
wheel that is bent or misaligned. The center hole
must be free of nicks or burrs.
2. Enter the offset, rim width, and wheel diameter
measurements into the balancer.
3. Lower the hood and spin the wheel. Remember
to use the fine balance mode. Proceed to Step 4
when your weight displays read 0.10 ounces or
less (you may need to trim weights to
accomplish this).
4. Raise the hood and attach a 4-ounce test weight
to the right side of the rim.
5. Lower the hood and spin the wheel. The reading
in the right weight display should be between
3.85 and 4.15.
6. Raise the hood and rotate the wheel until the
outer weight positioning lights flash. The test
weight should be in the 6 o’clock position. The
inner weight reading should be 0.15 ounces or
less (this figure is the result of the interference
between the two balancing planes).
7. Repeat Steps 4, 5, and 6 with the test weight on
the left side of the rim.
Calibration Procedure
1.
Mount a wheel that best represents the
tire/wheel size most commonly balanced on this
unit. In most cases, this will be a 14, 15, or 16-
inch diameter by 6 to 6-1/2-inch wide wheel.
Remember to remove any weights attached to
the wheel.
2. Enter the A (offset), W (width), and D (diameter)
measurements.
NOTE: It is important that you are accurate in
entering these measurements. Inaccurate
measurements will adversely affect your
calibration.
3. Press and hold SHIFT and press CALIBRATE.
“CAL 0” will appear in the displays to indicate
Calibration Mode.
4. Lower the hood and press START to spin the
wheel. Wait for the wheel to brake to a stop
before raising the hood.
5. The balancer will indicate a 4-ounce weight in
ounce mode (100 grams in grams mode). Rotate
the wheel until the right weight positioning lights
blink. Attach the weight at top dead center on
the right plane.
REMEMBER: The more accurate you are in
locating the weight on the wheel, the more
accurate your calibration.
6. Lower the hood and press START to respin the
wheel. When the wheel brakes to a stop,
calibration is complete and the balancer will
automatically exit the Calibration Mode.
