AUGER CLUTCH ADJUSTMENT
To adjust the auger clutch, refer to Final Adjustment
section of Assembly Instructions.
SHIFT ROD ADJUSTMENT
To adjust the shift rod, remove the hairpin clip and flat
washer which secure the shift rod to the shift arm
assembly. Refer to figure 8. Adjust as specified in
Assembly Instructions.
CARBURETOR ADJUSTMENT
A 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 com­
pensate 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 meth­
ods 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 15.
1. One Wheel Driving—Place klick pin in the out­
side axle hole on the right side. This position
gives power drive to the left wheel only, making
the unit easier to maneuver.
2. Both Wheels Driving—Place klick pin in the hole
in the hub next to the rim on the right side. This
position is good for heavy snow as there is power
drive in both wheels.
