Begin Balance procedures
From the Main Menu, select “F4” to enter the balance mode of operation.
6.2.1 WHEEL MOUNTING
Most standard wheels and many alloy wheels have accurately machined center holes, and they should be mounted
with center cones. Accurate balancing depends on accurate mounting of the wheel and correct seating of the cone
in the pilot hole. Insure that the wheel is centered on the shaft exactly as it will be mounted to the vehicle.
Before starting any balancing procedure it is very important that the wheel is mounted on the machine with the
proper adaptors. An incorrect centering of the wheel will result in considerable imbalance.
There are many types of wheels and John Bean supplies adaptors of high quality and durability for the large
majority. However if you meet special wheels which may require a specific adaptor, call your authorized John Bean
distributor.
Rims may be divided into these major groups:
1. Car rims with a true center hole. 2. Car rims without a center hole.
3. Car rims with an untrue center hole. 4. Light truck rims.
6.2.2 STANDARD WHEELS (BACK CONE MOUNT)
Mount the wheel as detailed below in Figure 18a.
1.
Mount proper cone against spring plate.
2. Mount wheel on shaft in the same manner as you would on the car.
3. Mount the Power Clamp nut along with proper pressure cup.
4. To operate the power clamp, lift the foot pedal to engage the clamp. Lift pedal again to release the nut.

6.2.3 CENTERING LIGHT-TRUCK WHEELS
Install the wheel, using the front cone method, See Figure 18b.
An optional offset spacer may be required for some light truck wheels and reverse-offset wheels that must be moved
away from the balancer mounting flange. The extension adaptor is often used with the 5-1/4 inch diameter light
truck cone.
WARNING - HOLD THE POWER CLAMP NUT BY THE PLAS-
TIC END CAP ONLY!! THE POWER CLAMP WILL NOT STOP
UNTIL THE WHEEL IS SECURE AGAINST THE FLANGE. SE-
VERE PERSONAL INJURY WILL OCCUR IF FINGERS OR
HAND IS PINCHED BETWEEN THE NUT, WHEEL OR FLANGE.
