This engine is certified to operate on gasoline. Exhaust Emission Control System:
EM (Engine Modifications).
Do not use gasoline which contains Methanol. Do not mix oil with gasoline.
Adding Fuel
Clean around fuel fill before removing cap. Fill tank to approximately 1-1/2 inches
below top of neck to allow for fuel expansion. Be careful not to overfill.
Before refueling, allow engine to cool 2 minutes.
WARNING
STARTING
CAUTION: Some engines may be equipped with Oil Gard. The Oil Gard is
intended to warn the operator that the engine is low on oil. Always check oil level
before starting. Engine damage may occur if the oil level is not properly
maintained and will void warranty coverage. If the engine will not start, has
stopped running and/or a light flickers in the stop switch, add oil (see oil
procedure Fig. 2).
BEFORE STARTING THE ENGINE
Fig. 3
1. Add oil and fuel as instructed in this manual.
2. Move choke control
Ê to CHOKE position.
3. Move throttle control
Ë to FAST position.
4. Turn fuel shut-off valve
Ì ON, if equipped.
5. Move stop control
Í to ON position, if equipped.
Note: OIL GARD light in rocker stop switch
Í, if equipped, warns of low oil level.
Light will flicker and engine will not start, or restart. Oil must be added. Fill to FULL
mark on dipstick or overflowing at oil filler plug. Do not over fill. OIL GARD, however,
will not stop a running engine if the engine runs low on oil.
STARTING THE ENGINE
Fig. 4
Rewind Starter
1. Grasp rope handle Ê and pull slowly until resistance is felt. Then pull cord
rapidly to overcome compression, prevent kickback and start engine.
2. Repeat if necessary with choke in RUN position and throttle in FAST. When
engine starts, operate in FAST position.
WARNING
Rapid retraction of starter cord (kickback) will pull hand and arm toward
engine faster than you can let go.
Electric Starter
1. On engines equipped with 12 volt starting systems, turn key to START
position
Ë.
2. Repeat if necessary with throttle control in FAST position. When engine
starts, operate in FAST position.
Note: If equipment manufacturer has supplied battery, charge it before trying to start
engine, as equipment manufacturer recommends.
Note: Use short starting cycles (15 sec. per minute) to prolong starter life. Extended
cranking can damage starter motor.
STOPPING
Fig. 5
1. Move throttle control lever to IDLE or SLOW position Ê, if equipped.
2. Then move stop control to OFF position
Ë or turn key to OFF Ì.
3. Close fuel shut-off valve

CAUTION: DO NOT move choke control to CHOKE position to stop engine.
Backfire or engine damage may occur.
Note: Always remove key from switch when equipment is not in use or left unat-
tended.
Note: When engine is transported, close fuel shut-off valve to prevent leakage.
