INITIAL SERVICING

The engine (Figure 6) must be checked for proper lubrication and filled with fuel prior to operation. Refer to the manufactur- ers Engine manual for instructions & details of operation and servicing.

	Fuel Hazard

Adding fuel to the tank should be done only when the engine is stopped and has had an opportunity to cool down. In the event of a fuel spill, DO NOT attempt to start the engine until the fuel residue has been completely wiped up, and the area surrounding the engine is dry.

2. Throttle Lever – Used to adjust engine RPM speed (lever advanced forward SLOW, lever back toward operator FAST).

	starting, OFF position stops engine operations.

	the starter grip until resistance is felt, then pull briskly and
	smoothly.

5. Fuel Valve Lever – OPEN to let fuel flow, CLOSE to stop

the flow of fuel.

NOTEfilter in need of replacement will allow dirt to enter the engine, causing rapid engine wear.
