Drive Clutch Cable Adjustment

Adjust the drive clutch control if the chipper shredder vacuum moves forward with the drive clutch control disengaged, if it does not self-propel with the drive clutch control engaged, or if drive belt is slipping (unit hesitates while engine maintains the same speed). Use the adjustment wheel located in the clutch control housing to tighten or loosen the clutch cable. In addition, the adjustment wheel may also be used to determine the position in which the drive clutch control is engaged. If it is more comfortable to have the drive engaged with the lever further away from the handle, tighten the clutch cable. See Figure 9.

Nozzle Door Height Adjustment

The nozzle adjustment levers are located on each side of the nozzle door. The nozzle door can be adjusted to any of five positions, ranging from 1/2” to 3” ground clearance that will provide the best performance for the operating conditions. Slide the height adjustment lever forward or backward for adjusting the nozzle door upwards or downwards. Height must be adjusted equally. In general, raise the nozzle to vacuum a thick layer of leaves and lower the nozzle for smooth surfaces. See Figure 8.
