Before Starting Engine:
Mixing Fuel / 2-Cycle Oil
WARNING
Do not smoke or allow smoking near fuel or the Blower. Mix and pour fuel outdoors WHERE THERE ARE NO SPARKS
OR FLAMES.
The 2-cycle engine on your Blower requires that fuel and
2-cycle engine oil be pre-mixed before adding to the
Blower's fuel tank. To mix the fuel/ 2-cycle oil:
1. Use fresh unleaded gasoline with an octane rating of
87 or higher.
CAUTION
Use of gasoline containing ethanol or methanol can damage
Blower.
2. Always use 2-cycle oil that meets or exceeds JASO – FC
specifications and is intended for mixing at a fuel/oil ratio of 40:1.
3. Do not use automotive or 2-cycle marine outboard oil.
These will damage your Blower's engine and void the warranty.
4. Always mix the gasoline and 2-cycle oil in a container
approved for gasoline. Never mix fuel directly in the
Blower's fuel tank.
5. Follow instructions on 2-cycle oil container for mixing
fuel. Mix gasoline and 2-cycle oil at a ratio of 40:1. A

mixture with a 40:1 ratio is obtained by mixing 1 gallon
(4 liters) of gasoline with 3.2 ounces of oil (95 ml). After
adding oil to gasoline, shake container momentarily to
ensure proper mixing.
6. Mix only enough fuel for your immediate needs. Do not
store pre-mixed fuel.
7. Stop engine and allow to cool before refueling.
8. To fill the Blower's fuel tank with the gasoline/ oil
mixture, place the Blower upright on the ground or on a
sturdy bench and wipe and any debris from around the
fuel cap.
9. Remove fuel cap slowly and use a funnel to pour the
mixture into the tank, and replace the fuel cap.
10. Avoid spilling fuel or oil. Wipe up all fuel spills.
11. Move at least 10 feet (3 meters) away from fueling site
before starting engine.

Engine Break-In Period:
During the first ten (10) hours of use, use the slowest engine speed which allows for effective usage and avoid operation
at high engine speeds for extended periods of time. This will maximize the life and performance of your blower's engine.
Maximum power will be achieved after the first ten (10) hours of engine operation.
