II.  How to Get Service

For engine adjustments, repairs or warranty service not 
covered in this manual, contact your nearest Authorized 
Tecumseh Servicing Dealer. Find them on our website at 
www.TecumsehPower.com or call Tecumseh Power 
Company at 1-800-558-5402.

A.  Engine Identification Decal

A sample decal located on your engine indicates your 
engine’s model number, specification and the date of 
manufacture (D.O.M.). Please look at the decal on your 
engine and fill in this information in the spaces provided for 
future reference. See Figure 5.

The Engine Identification

 

Decal includes engine life 

specifications for the emissions-related useful life period of 
your engine. This period relates to the emission 
compliance life as certified by EPA and/or CARB. To find 
the life period specification for your engine, please look on 
your decal and find the letter enclosed by quotation marks 
between the words MODERATE and LIFE PERIOD. Match 
one of the following letters with the letter printed on your 
decal. For example, OH195EA/OH195EP models are 
designated as “C”125 hours, “B” 250 hours and “A” 500 
hours. LH318EA (HM80-90), LH358EA (HM100) and 
OH318EA models are designated as “C”250 hours, “B” 500 
hours and ”A” 1000 hours.

B.  Tecumseh Technician’s Handbooks

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 Tecumseh 
Servicing Dealer. See Figure 6. 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 Tecumseh Power Sport 
Engines. Order as part no. 695244A for
OH195EA/OH195EP and OH318EA models. Order as part 
no. 692509 for LH318EA (HM80-90), LH358EA (HM100) 
models.
