The correct fuel/oil mixture ratio for the five horsepow-
er engine is 50 to 1. Use fuel/oil mixture chart shown.
NOTE: To prevent damage to engine, carefully
observe recommended fuel to oil mixing ratio and
procedures.
WARNING
• Gasoline and oil must be premixed in a clean fuel
container.
Gasoline is highly flammable and must be handled
with care. Never fill the tank when the engine is hot
or running. Always move outdoors to fill the tank.
Keep snowthrower and gasoline away from open
flame or spark.
• Always use fresh, unleaded, winter grade fuel
• Never put plain, unmixed fuel into fuel tank. Shake
fuel container each time before filling fuel tank.
• Never use “stale” fuel left over from last season or
stored for long periods.
• DO NOT USE MULTI VISCOSITY OILS, SUCH AS
10W-30 or 10W-40.

cycle oil — 2.5 ounces (80 ml) into fuel container
for one gallon (4 liters) of fuel. (NOTE: DO NOT
USE MULTI VISCOSITY OILS, SUCH AS 10W-30
or 10W-40.)
3. Reinstall cap on the fuel container and shake con-
tainer vigorously so oil mixes with gasoline.
4. Unscrew cap and fill container with fuel. Shake
container again.
5. Remove fuel tank cap and carefully pour mixed fuel
into the fuel tank, filling to 1/2 inch (1.5 cm) below
filler neck to allow room for expansion. Never put
plain, unmixed fuel into fuel tank. Shake fuel
container each time before filling fuel tank.
