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 lever is
engaged.(fi g. 12) Adjust by tightening or by loosening clutch
cable adjusting nut as required, located at the clutch lever
(fi g. 12). If further adjustment is required, primary adjuster
is 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 adjustment can
cause drive clutch to slip and overheat, greatly reducing
machine performance and transmission life.
