Carburetor

WARNING: If any adjustments need to be made to the engine while the engine is running (e.g. carburetor), keep clear of all moving parts. Be careful of muffler, engine and other surrounding heated surfaces.

•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. Follow the steps below for adjustment. See Figure 20.

•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.

Both Wheels Driving

•Rotate wheel assembly to align hole in the hub with the inner hole on the axle shaft. Insert klick pin in the hole. Outer axle shaft hole should be visible. See Figure 20.
