building or other equipment and not covered 
with any material.
2. Refer to all warning labels prior to starting.
3. Check oil level using oil fi ll cap. Add oil if low. 
Do not overfi ll.
4. Check fuel level (G). Add fuel if low. Stop 
refueling when indicator reaches F (full) 
level. Check fuel system components and 
lines for leaks. Never refuel while unit is 
running.
5. Check that air cleaner components and all air

Starting
 WARNING
Rotating Parts can cause severe 
injury.
Stay away while engine is in 
operation.
Keep hands, feet, hair, and clothing away 
from all moving parts to prevent injury. Never 
operate engine with covers, shrouds, or 
guards removed.
NOTE:  Choke is not required to start a warm 
engine. Push choke lever (J) in to 
original position.
1. Turn Fuel ON.
2. Turn choke lever (J) ON.
3. Turn engine to ON and pull rope.
5. Turn choke lever (J) OFF after engine is 
warm.
If engine does not start, repeat operation until 
engine starts by gradually opening choke lever 
(J).
Cold Weather Starting
1. Use proper oil for temperature expected.
2. Disengage all possible external loads.
3. Use fresh winter grade fuel. Winter grade 
fuel has higher volatility to improve starting.
Operation
 CAUTION
Hazardous Voltage.
Backfeed to utility system can 
cause property damage, severe 
injury, or death.
Never plug a portable generator directly into 
a building outlet.
If generator is used for standby power, 
have a certifi ed, licensed electrician install 
an automatic transfer switch to prevent 
inadvertent interconnection of standby and 
normal sources of supply.
When running speed of generating set has 
stabilized (approximately 3 minutes):
1. Check that circuit protectors (C) are pushed 
in. Press if necessary.
2. Connect appliances to electrical sockets (B & 
D) of generator.
Angle of Operation
Do not operate this engine exceeding maximum 
angle of operation; see specifi cation table.
