ADJUSTING THE CONTROLS
Warning - The rotor must not start turning before the related
controls have been operated. This condition is achieved by means
of the control lever adjusting screws (B, Fig.41). In addition, the
lever that controls the cutter drive must start the cutter only after
movement of no more than 8 mm (Fig.41). If the adjusting screws
are insufficient to achieve this condition (adjusting screw at end of
thread) contact an authorized service center.
SEDIMENT CUP
Cleaning
WARNING - Gasoline is highly
flammable and explosive, and you can be
burned or seriously injured when handling
fuel.

Stop engine and keep heat,
sparks, and flame away.

Handle fuel only outdoors.

Wipe up spills immediately.
1. Move the fuel valve to the OFF
position, then remove the fuel
sediment cup and O-ring.
2. Wash the sediment cup in
non-flammable solvent, and dry it thoroughly.
3. Place the O-ring in the fuel valve, and install the sediment cup. Tighten the sediment cup
securely.
4. Move the fuel valve to the ON position, and check for leaks. Replace the O-ring if there is any
leakage.
SPARK PLUG
Recommended Spark Plugs: BPR6ES (NGK) or
W20EPR-U (DENSO).
The recommended spark plug has the correct heat range
for normal engine operating temperatures.
WARNING - An incorrect spark plug can cause
engine damage.
For good performance, the spark plug must be properly
gapped and free of deposits.
1. Disconnect the spark plug cap, and remove any
dirt from around the spark plug area.
2. Remove the spark plug with a 13/16-inch spark
plug wrench.
3. Inspect the spark plug. Replace it if damaged or
badly fouled, if the sealing washer is in poor
condition, or if the electrode is worn.
4. Measure the spark plug electrode gap with a wire
type feeler gauge. Correct the gap, if necessary,
by carefully bending the side electrode.
The gap should be:
0.70 0.80 mm.
5. Install the spark plug carefully, by hand, to avoid
cross-threading.
6. After the spark plug is seated, tighten with a
13/16-inch spark plug wrench to compress the
sealing washer.
7. When installing a new spark plug, tighten 1/2 turn
after the spark plug seats to compress the
washer.
8. When reinstalling the original spark plug, tighten
