IV. Before Starting Your Engine

A. Mixing Fuel and Oil

NEVER store engine with fuel in the 
fuel tank inside a building with 

potential sources of ignition such as hot water or space 
heaters, clothes dryers, electric motors, etc. Doing so may 
lead to an explosion resulting in death or serious injury.

 NOTES

DO NOT mix fuel and oil directly in fuel tank.

Use of NMMA, TC-WII or TC-W3, JASO FB or JASO FC 
classified oil is recommended. 

Contact your Authorized TecumsehPower Servicing Dealer 
for TecumsehPower Oil.

1.

Be sure container is outdoors and in a well-ventilated 
area.

2.

Fill approved clean red GASOLINE container with 1/4 
of recommended fuel amount. See Tables 1, 2 and 3 
on page 3. Afterward, continue reading instructions 
below.

3.

Add required amount of recommended oil to fuel. See 
Table 1 for ice augers, Table 2 for all other applications 
on page 3. Afterward, continue reading instructions 
below.

4.

Screw cap onto container.

5.

Shake container vigorously.

6.

Unscrew cap from container.

7.

Fill container with remainder of recommended fuel. 
See Tables 1, 2 and 3 on page 3. Afterward, continue 
reading instructions below.

8.

Wipe away any spilled fuel or oil.

B. Filling Fuel Tank

An adult should fuel this engine. 
NEVER allow children to refuel this 

engine. Gasoline (fuel) vapors are highly flammable and 
can explode. Fuel vapors can spread and be ignited by a 
spark or flame many feet away from engine. To prevent 
injury or death from fuel fires, follow these instructions:

1.

Stop engine and allow it to cool before refueling.

2.

Be sure engine is outdoors and in a well-ventilated 
area.

3.

Clean area around fuel fill cap and remove fuel fill cap. 
See Figure 5.

 NOTES

For recommended mixture ratios of fuel and oil, see Tables 1, 
2 and 3 on page 3. See “A. Mixing Fuel and Oil” instructions 
above. Afterward, continue reading instructions below.

4.

Using an approved red GASOLINE container, add fuel 
mixture slowly, being careful to avoid spilling. DO NOT 
overfill fuel tank. Leave space in the tank to allow fuel 
to expand without overflowing.

5.

Replace fuel fill cap securely and wipe up spilled fuel 
mixture before starting engine. If fuel mixture is spilled 
DO NOT start engine. Move machine away from area 
of spillage. Avoid creating any source of ignition until 
fuel vapors are gone.

 NOTE

Replace a damaged or missing fuel fill cap only with a 
genuine TecumsehPower replacement Fuel Fill Cap. 
Failure to do so may 

VOID YOUR WARRANTY
