Test the operation of the unit. Repeat the adjust-
ment if necessary.
NOTE:
Most comfortable operation will be
obtained when the adjustment allows the lever to
just make contact with the hand grip when suffi-
cient traction is achieved.

WHEEL BRAKE ADJUSTMENT
This adjustment may be required it the unit does not
hold on a hill with the operator presence control disen-
gaged, or if the brake drags with the operator presence
control engaged and the transmission is in neutral.
(The unit should roll freely in this position.)
NOTE:
With the operator presence control
released there should be a 3/8” to 5/16” gap
between the back of the brake arm and the
bracket. See Figure 29.

To adjust use a 1/2” wrench to make a small (1/4
turn) adjustment to the brake locknut until the
correct measurement is achieved. It may be nec-
essary to relieve spring tension when decreas-
ing distance. Have an assistant engage the
operator presence control while you adjust the
nut. See Figure 30.

TRANSMISSION NEUTRAL ADJUSTMENT
With the unit turned off and the shift lever in the neutral
detent position you should be able to hold down the
operator presence control and roll the unit easily for-
ward and back. Check this from forward and reverse
positions. If the unit is in gear you will need to perform
a neutral adjustment.
10.1. Place the shift lever in the neutral detent position
of the console. See Figure 31.
