4.0 OPERATION OF THE BALANCER

WARNING: For operator safety please
read and follow the precautions outlined
on pages 1 and 2 of this manual.
NOTE: Read all instructions before pro-
ceeding with operation of the balancer.
All balancer functions are input into the main computer
through the large easy to read touch panel. Although
each wheel tire assembly differ in some ways all bal-
ancing jobs require basically the same procedure. The
order of events to take place are:
1. Inspection of the wheel/tire assembly
2. Mounting wheel onto shaft or adapter
3. Selection of Balancing Mode and Preferences
4. Entry of wheel parameters
Note: During an Alu P SAPE Arm detection the Easy Alu
function automatically sets the desired weight location
by a suitable ALU mode selection.
5. Spinning the wheel
6. Applying the recommended weight
7. Check spin if desired
8. Dismounting the wheel
The following operation instructions will follow the basic
outline above.

4.1 CHECK LIST - INSPECTION

Observe Before Balancing Wheel
1. Check for proper air pressure. If not correct, infl ate
to correct pressure.
2. Check for any foreign material inside tire. If present,
remove before balancing tire.
WATER IS FOREIGN MATERIAL!
3. Remove old weights — old weights may be improper
value or in wrong location.
4. Be sure tire and wheel are free of excessive dirt,
rust and large stones. Use wire brush on back side of
wheel if necessary.

4.2 WHEEL MOUNTING

Nearly all 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 im-
portant that the wheel is mounted on the machine with
the proper adap tors. An incorrect centering of the wheel
will result in considerable imbalance.
There are many types of wheels and Snap-on supplies
adaptors of good quality and durability for the large ma-
jority. However if you meet special wheels which may
require a specifi c adaptor, call your Snap-on 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.
5. Lug centric wheels
6. Clad wheels

4.2.1 STANDARD WHEELS (back cone mount)

Mount the wheel as detailed below in Figure 11
1. Mount proper cone against spring plate.
Figure 11
2. Mount wheel on shaft in the same manner as you
would on the car.
3. Mount pressure cup on shaft and place against
outside of wheel, follow with the Quick-nut.
4. Tighten Quick-nut securely with both hands. To
operate the Quick-nut pull the lock-unlock lever
(A, Figure 11). Slide the Quick-nut on the thread-
ed shaft. When in contact with the rim, release
the unlock lever and tighten fi rmly. To assist in
centering the wheel properly, rotate the wheel on
the shaft while tightening the quick nut.
