E. DO NOT Modify Engine

To avoid serious injury or death, DO NOT modify engine in 
any way. Tampering with the governor setting can lead to a 
runaway engine and cause it to operate at unsafe speeds. 
NEVER tamper with factory setting of engine governor.

!

WARNING

F.

Avoid Burns and Fire from Hot Surfaces

The muffler and other engine parts become 
extremely hot during operation and remain 
hot after the engine has stopped. 

• To avoid severe burns on contact, 

STAY AWAY from hot areas of 
engine. DO NOT operate the engine 
without the muffler guard in place, 
if equipped.

• To reduce the risk of fire keep all materials that can 

burn, including grass and leaves, away from muffler 
and rest of engine. DO NOT operate, idle or park 
engine powered equipment in long dry grass or 
other dry ground cover.

G. Avoid Accidental Starts

To prevent accidental starting when working on equipment 
always:

• Carefully disconnect spark plug wire and keep it 

away from spark plug. See Figures 3 and 4.

• Keep the disconnected spark plug wire 

securely away from metal parts where arcing 
could occur. 

• Carefully attach the spark plug wire to the 

grounding post, if provided. 

• Disconnect battery at negative terminal first, if 

engine is equipped with a DC electric starter.

• Turn all engine switches to “OFF” position.

• Remove ignition key, if provided.

H. Use Hearing Protection

Engine noise may cause hearing damage. Always wear 
hearing protection when operating an engine.

Use of this engine on fun-carts, go-karts, or mini-bikes
can result in serious injury or death. TecumsehPower

for use in such applications. Consult your local Authorized
