OPERATION AND MAINTENANCE

It is the owner’s/operator's responsibility to perform all safety
checks; to make sure that all maintenance for safe operation is
performed promptly; and to have the engine checked by an
authorized dealer periodically. Normal maintenance service and
replacement of parts are the responsibility of the owner/operator
and, as such, are not considered defects in materials or
workmanship within the terms of the warranty. Individual
operating habits and usage contribute to the need for
maintenance service.

Proper maintenance and care of your engine assures a minimum 
number of problems and keeps your operating expenses at a
minimum. See your authorized dealer/distributor for service aids
and accessories.

BEFORE STARTING THE ENGINE

Perform the following tasks before trying to start the engine:

ADDING ENGINE OIL

1.

Remove the yellow oil fill cap from the crankcase (Figure 1).

2.

Add engine oil until the oil level is to the point of overflowing.

Figure 1 — Oil Fill Cap

CHECKING ENGINE OIL

1.

Check the engine oil level before starting the engine each
time after the initial start. If the oil level is below the point of 
overflowing, fill to the proper level.

ADDING FUEL

1.

Fill the fuel tank using clean, fresh UNLEADED gasoline.

STARTING THE ENGINE

1.

Open the fuel shut-off valve, if so equipped.

2.

If your unit is equipped with the IDLE/CONTROL feature,
locate the IDLE/CONTROL ON/OFF SWITCH on the control
panel, and set it to the OFF (O) position.

3.

Locate the RUN/STOP SWITCH (Figure 2) next to the
engine cylinder head and push it to RUN.

Figure 2 — RUN/STOP SWITCH

If your engine is equipped with a choke, use the 
following instructions:

1.

Place the choke lever in the FULL CHOKE POSITION
(Figure 3) by sliding it to the left (towards the valve cover),
in the direction indicated by the arrow.

Figure 3 — Choke Position

Grasp the recoil handle (Figure 4) and pull it slowly until you
feel slight resistance, then PULL QUICKLY.
