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".
(c) Rotate wheel
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.
