IMPORTANT: Always release the drive clutch
handle before moving the shift lever.
• With the engine running near top speed, move shift
lever into one of the six FORWARD _ositions or

counterclockwise to lower. (Be careful not to turf

The best height for the nozzle will vary according to
the conditions. Adjust the height of the nozzle to find
the setting which gives the best performance for the
operating conditions. In general, raise the nozzle to
vacuum a thick layer of leaves; lower the nozzle for
smooth surfaces.
