SAFETY WARNINGS FOR GAS
TRIMMERS

WARNING:

Gasoline is highly flammable and 

its vapors can explode if ignited. Take the
following precautions:

1) Store fuel only in containers specifically 

designed and approved for the storage 
of such materials.

2) Always stop the engine and allow it to 

cool before filling the fuel tank. Never 
remove the cap of the fuel tank, or add 
fuel, when the engine is hot.

3) Pressure can build up in the fuel tank. 

Loosen the fuel tank cap slowly to relieve 
any pressure in the tank.

4) Add fuel in a clean, well-ventilated area. 

Wipe up any spilled fuel immediately. If 
fuel has been spilled, avoid creating a 
source of ignition or starting the engine 
until fuel vapors have dissipated.

5) Ensure correct fuel or fuel/oil mixture is 

used. Never operate the unit without the 
fuel cap securely in place.

6) Move the unit at least 10 feet (3 m) 

from the fueling point before starting the 
engine. Do not smoke, keep sparks and 
open flames away from the area while 
adding fuel or operating the unit.
