SELF PROPELLED DRIVE ADJUSTMENT
17.3
Tools required: two 1/2 wrenches.
As the clutch wears, adjustments may be required to maintain
proper control cable tension, and clutch engagement (fi g.
11). If the clutch begins slipping or squealing during normal
operation it may require an adjustment to increase the
clutch cable tension. A properly adjusted drive clutch should
require a minimum of 3/8" of spring stretch when drive bail is
engaged.(fig. 12) Adjust by tightening or by loosening
clutch cable adjusting nut as required, located at the
underneath the engine base (fig. 13). Replacement of
cable may be necessary if adjustment will not allow for
proper drive clutch.
WARNING: If the drive clutch begins to squeal or slip,
do not continue to operate your unit until adequate
adjustment or repair has been performed. Improper adjust-
ment can cause drive clutch to slip and overheat, greatly
reducing machine performance and transmission life.
