AUGER CLUTCH ADJUSTMENT
To adjust the auger clutch, refer to Final Assembly
and Adjustments section on page 9.
CARBURETOR ADJUSTMENT
WARNING: If any adjustments are
made to the engine while the engine is
running (e.g. carburetor), keep clear of all
moving parts. Be careful of heated
surfaces and muffler.
Minor carburetor adjustment may be required to
compensate for differences in fuel, temperature,
altitude and load.
Refer to the separate engine manual packed with
your unit for carburetor adjustment information.
DRIVE WHEELS
The wheels may be adjusted for two different
methods of operation. The adjustment is made by
placing the klick pins in one of two different holes on
the right side of the unit. See Figure 19.
1. One Wheel Driving—On the right side of the
unit, place klick pin in the outside axle hole only.
Do not place pin through wheel hub. This
position gives power drive to the left wheel only,
making the unit easier to maneuver.
2. Both Wheels Driving—Rotate wheel assembly
to align hole in hub with inner hole on axle
shaft. Insert klick pin in hole. Outer axle shaft
hole should be visible. See Figure 19.
