OPERATION
PREPARING ENGINE FOR STARTING
Before starting your edger, make sure the black throttle cable
housing is seated all the way into the brass ferrule at the engine
side of the cable.
GAS AND OIL QUALITY
To operate the engine, we recommend using Viper® brand two-
cycle oil (P/N 300400) to ensure that the engine operates cor-
rectly throughout the life of the engine. Use unleaded regular
gas only.
NOTE: Viper® oil can be purchased from our web site at www.
getearthquake.com.
MIXTURE
Run engine with a 50:1 ratio.
MIXING FUEL AND FILLING FUEL TANK
MIXING FUEL
1. Fuel must be mixed in a container outside in a well-ventilated
area.
2. Fill certified fuel container 1/4 full of recommended fuel. Use
unleaded regular gas only. It is best to use premium gasoline
that has no ethanol content.
3. Add recommended amount of two-cycle oil. Earthquake®
also suggests the use of a fuel stabilizer/additive to prevent
gasoline from oxidizing and gumming up the carburetor.
4. Screw container cap on straight and tight.
5. Shake the container to mix fuel and oil.
6. Unscrew fuel cap slowly to vent; add the remainder of fuel
requirements.
7. Wipe away any spilled fuel or oil and allow to evaporate before
moving or transporting.
