Operator manual packed with your unit. Read and follow
instructions carefully.
Check engine oil level before each use as
instructed in the separate engine manual.
Clean or replace
air cleaner every 25 hours under
normal conditions. Clean every few hours under
extremely dusty conditions. To service the air
cleaner, refer to the separate engine manual.
The
spark plug should be cleaned and the gap
reset once a season. Refer to the separate engine
manual for correct plug type and gap specifications.
Clean engine regularly with a cloth or brush. Keep
area around engine clean to permit proper air
circulation. Remove all grass, dirt and combustible
debris from muffler area.
Drive Control Cable Adjustment
Adjust the drive control cable if the yard vacuum does
not self propel with the drive control engaged, or if the
unit hesitates while the engine maintains the same speed
after approximately 20 hours of use.
To move the z-fitting of the drive control cable from its
factory set position in the front hole of the drive control to
the rear hole, proceed as follows:
1. a. Push the right side of the control out of the right
hole in the upper handle. See Figure 5-1A.
b. Pivot control down towards the lower handle.
c. Pivot straight up to remove it from the left hole in
the upper handle. See Figure 5-1A.
2. There is now sufficient slack in the drive control cable
to grasp the z-fitting with your hand and move it from
the front hole to the rear hole of the drive control. See
Figure 5-1B.
