NOTE

Pedal must be at "OFF" position.

(a) Place wheel on balancer, outside face up. Valve stem nearest

to the black pointer in the bubble.

(b) Wheel must seat flat on balancer flange to assure accurate

reading.

(3) Locate the out-of-balance.

(a) Move pedal to

"ON" position.

(b) Steady the

wheel with your fingertips to

stop the oscillation. The

bubble always floats toward

the center of the light area

and indicates the starting

position "W".

until light spot "W" is in

front of you -- DON'T WALK

AROUND THE BALANCER!

(4) Select weights of

proper size. The bubble must

center or pass over center "X"

when 4 weights of the same

size in 2 pairs 1" apart are

placed at point "W". You must

always use 4 weights. Try 4

"A" weights first; if they are

too light, replace with 4 "B"

weights; if these are too

light, use 4 "C" weights.

NOTE

If 4 "C" weights do not make bubble center or pass over center, wheel

should not be balanced in this condition.

The assembly of wheel and tire contributes to the balancer condition of

the unit.

It is possible for the heavy portion of each to coincide.

This concentration of weight may be relieved by deflating tire and

turning it on the rim, halfway round, and reinflating.

A wheel requiring more than 4 "C" weights will. not stay in balance.

(5) Balance the wheel by moving the weights.
