WHEEL BRAKE ADJUSTMENT

This adjustment may be required
if the machine does not hold on a
hill with the Operator Presence
Control disengaged, or if the brake
drags with the Operator Presence
Control engaged and the transmis-
sion in neutral.
1. Stop engine, wait for all parts
to stop moving, and disconnect
spark plug wire.
2. Disengage (release) the
Operator Presence Control (M,
Figure 5-13).
3. Slowly adjust at nut (O), if nec-
essary, until the distance between
the back of brake arm (N) and
bracket (P) is 3/8"-5/16". Use
small adjustments (1/4 turn maxi-
mum). NOTE: It may be neces-
sary to relieve spring tension when
decreasing distance. To do so,
have an assistant engage the
Operator Presence Control while
you adjust the nut.
TRANSMISSION NEUTRAL
ADJUSTMENT
Follow this procedure to adjust
neutral on the transmission.
1. Stop engine, wait for all parts
to stop moving, and disconnect
spark plug wire.
2. Rotate shift rod (I, Figures 5-14
and 5-15) clockwise until it stops
in the neutral (N) position (from
forward gear positions).
3. Hold down Operator Presence
Control (M, Figure 5-13) and push
unit forward and backward. Unit
should move freely. If not, con-
tinue with Step 4.
4. Remove cotter pin securing
shift link (P, Figure 5-15) to shift
rod (I).
5. Move shift arm (X) back and
forth as necessary into each detent
until transmission is in neutral.
NOTE: Moving shift arm (X)
clockwise all the way to the left,
and then one notch back counter-
clockwise, should put transmission

into neutral. When transmission is
in neutral, unit will move freely
when pushed while holding the
Operator Presence Control lever
down. If transmission is NOT in
neutral, there will be a slight drag
on the wheels when pushing unit.
6. When shift arm (X) is in neutral
position, rotate shift link (P) until
hooked end fits back into hole in
bottom end of shift rod (I).
