A. Engine Identification Decal
A sample engine identification decal is located in the next
column and indicates the engine’s model number,
specification and date of manufacture (DOM). See Figure 3.
NOTES
Please look at the decal on your engine.
Fill in the engine information in the spaces provided for

B. Technician’s Handbook
If you have a general understanding of internal combustion
engines and wish to repair and service your engine and/or
engine emission control systems yourself, a Technician’s
Handbook is available from your Authorized
TecumsehPower Servicing Dealer. See Figure 4. This
handbook covers repairs and adjustments not covered
within this Operator’s Manual, and it is intended for
individuals who have had adequate training, experience
and who practice proper tool usage. Service procedures
should be clearly understood and practiced when servicing
TecumsehPower engines.
• Order as part #692508 or #740047 for TV Models.
TecumsehPower Company manufactures and is
responsible only for the engine used on this power
equipment. If repair or service is needed for anything other
than the engine, contact the service source recommended
by the equipment manufacturer.
III. Oil and Fuel Specifications
A. Oil
To operate your engine you need to use a clean, high
quality, 2-cycle oil mixed with fuel. For recommended
mixture ratio of fuel and oil, see Table 1 for ice augers and
Table 2 for all other applications. See "A. Mixing Fuel and
Oil" instructions on page 4. Afterward, continue reading
instructions below.
NOTES
Use of NMMA, TC-WII or TC-W3, JASO FB or JASO FC
classified oil is recommended.
Special-formulated oils are available at your Authorized
TecumsehPower Servicing Dealer.
B. Fuel
Use
unleaded regular, unleaded premium or reformulated
automotive fuel only. You may use gasoline containing the
components identified in Table 3.
• DO NOT use leaded fuel.
• Fuel must be fresh and clean. NEVER use fuel left
over from last season or stored for long periods.
• DO NOT use fuel containing Methanol (Wood Alcohol).
The use of alternative fuels such as E85
or E20 are NOT recommended for use
in TecumsehPower engines. Alternative fuels with high
alcohol content can cause hard starting, poor engine
performance, and may cause internal engine damage.
NOTE
Damage and/or performance problems that occur from use
of fuel other than those listed in the Operator’s Manuals will
not be considered warranty.
