Service

1.

Use extreme care in handling gasoline and other fuels. 
They are extremely flammable and the vapors are 
explosive.

2.

Store fuel and oil in approved containers, away from heat 
and open flame, and out of the reach of children.

3.

Check and add fuel before starting the engine. Never 
remove gas cap or add fuel while the engine is running. 
Allow engine to cool at least two minutes before refueling.

4.

Replace gasoline cap securely and wipe off any spilled 
gasoline before starting the engine as it may cause a fire 
or explosion.

5.

Extinguish all cigarettes, cigars, pipes and other sources 
of ignition.

6.

Never refuel unit indoors because flammable vapors will 
accumulate in the area.

7.

Never store the machine or fuel container inside where 
there is an open flame or spark such as a gas hot water 
heater, clothes dryer or furnace.

8.

Never run your machine in an enclosed area as the 
exhaust from the engine contains carbon monoxide, 
which is an odorless, tasteless and deadly poisonous 
gas.

9.

To reduce fire hazard, keep engine and muffler free of 
leaves, grass, and other debris build-up. 

10. Clean up fuel and oil spillage. Allow unit to cool at least 5 

minutes before storing.

11. Before cleaning, repairing, or inspecting, make certain 

the impeller and all moving parts have stopped. 
Disconnect the spark plug wire and keep wire away from 
spark plug to prevent accidental starting. Do not use 
flammable solutions to clean air filter.

12. Keep all nuts, bolts, and screws tight to be sure the 

equipment is in safe working condition.

13. Never tamper with safety devices. Check their proper 

operation regularly.

14. Do not alter or tamper with the engine’s governor setting. 

The governor controls the maximum safe operating 
speed of the engine. Over-revving the engine is 
dangerous and will cause damage to the engine and to 
other moving parts of the machine.
