ADJUSTING THE UNIT TO TRACK
STRAIGHT
The primary reason the unit may not track straight is
incorrect or unbalanced tire air pressure. First, check
and adjust tire pressure. Increase pressure on the side
the unit tracks toward. DO NOT exceed maximum
recommended tire pressure. See
Specifications .
If adjusting tire air pressure does not the solve tracking
problem the steering control lever travel may need to
be adjusted.
To check steering control levers:
With the engine off, push the steering control levers to
their full forward position. If one lever travels farther
than the other, they need to be adjusted.
To adjust:
1. Remove side shrouds. Set aside.
2. Loosen bolts which attach the eccentric to the
seat support. Do not remove the bolts.
3. Rotate eccentric to adjust the travel of the speed
control arm. The thicker portion of the eccentric
shortens the distance the steering control lever
will travel forward. The thinner portion of the
eccentric lengthens the distance the steering
control lever will travel forward.
CAUTION: PREVENT personal injury!
ALWAYS MAKE CERTAIN that jack(s) or
blocks used are stable, strong and will
support the weight of the unit.
