2. If the bubble does not float to the middle of or beyond
the circle, replace the “A” weights with four “B” weights
(heavier). Likewise if the bubble does not center or go
beyond the circle replace the four “B” weights with four “C”
weights (heavier).
NOTE:
It is possible that the four “C” weights may not
balance the wheel when the heavy portion of both the
wheel and the tire are located on the same side.
If this condition exists, deflate the tire and rotate it
approximately half way around the rim and then
re-inflate the tire and repeat the process.
3. After you have determined which four weights to use
and have placed them in pairs as shown in Figure 1, move
the pairs in opposite directions from each other around the
rim equal distance from the starting point, until the bubble
is centered in the black circle. (See Fig. 4)
4. Draw a vertical chalk line on the tread of the tire
directly in the middle of each pair of weights. To accurately
draw lines, sight through the middle of the weights to the
middle of the balancer. (See Fig. 5 )
5. Remove the two pairs of weights and lift the tire from
the balancer. Attach one weight on the inside (underside)
of the tire directly in line with each of the chalk marked on
the tire thread.
6. Return the wheel to the balancer “outside” face up and
lay one each of the remaining weights on the rim of
approximately in line with each chalk lines. To check
for balance move weights slightly apart or together until
the bubble is in the middle of the black circle. Attach the
remaining weights to the outside of the rim flange.
