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.
