Drive Cable Adjustment
It may be necessary from time to time to adjust the drive cable
used to engage the tires and propel the unit forward. If the unit
does not propel itself with the drive control engaged, or if the
unit’s wheels hesitate with the drive control lever fully engaged,
follow these instructions to properly adjust the drive cable:
1. Locate the thumb wheel on the drive cable just above the
drive control lever on the power base, see Figure 6-9.
2. With the engine running, roll the thumb wheel counter-
clockwise until the wheels begin to move forward slightly,
then back it off approximately one quarter turn.
