COATS 1100 Series Balancer - Manual (Page 16)

12 • Important: Always read and follow instructions.
Direct Select™ Weight Location
Before spinning the wheel, use direct select to indicate
weight placement locations on the wheel as follows:
Figure 16 - Direct Select™ Weight Keys & Wheel Cross-
section Diagram
Note: When the machine is turned ON, the balancer
defaults to a 2-plane dynamic mode using standard
clip-on wheel weight locations (Clip 1 and Clip 2) and
wheel dimensions.
Clip 1 (default) - select this location to place a stan-
dard clip weight on the Inboard rim flange.
T1 Tape - select this location to place an adhesive
weight on the Inboard side of the wheel that is the
horizontal plane at the outer edge.
T2 Tape - select this location to place an adhesive (hid-
den) weight on the Outboard side of the wheel that is
the horizontal plane in the inner area.
T3 Tape - select this location to place an adhesive
weight on the Outboard side of the wheel that is the
horizontal plane at the outer edge.
Clip 2 (default) - select this location to place a stan-
dard clip weight on the Outboard rim flange.
Setting Wheel Dimensions (DIM)
Before a wheel can be balanced, wheel dimensions
must be entered into the computer.
Definition of Dimensions (DIM)
A = Offset
The distance measured from the balancer (“0” on off-
set arm) to inner plane of the rim (inner weight location).
W = Width
The width of the wheel at the rim flanges, measured
with the calipers as shown in figure 19.
Note: Only use calipers provided by the wheel bal-
ancer manufacturer because others may not be the
same.
D = Diameter
The diameter of the wheel as indicated on the tire.
Note: A thick flange, on some aluminum wheels, can
effect the measured diameter. For example, a 16-inch
rim can have a measured diameter of 15.5-inches.
Figure 17 - W, D, and A Tire Dimensions
A2 = Offset
The distance measured from the balancer (“0” on
offset arm) to outer plane of the rim (outer weight loca-
tion). Used only for adhesive weight location.
D2 = Diameter
The diameter as measured at the A2 weight location.
Used only for adhesive weight location.
