SAFETY WARNINGS AND NOTES
The purpose of safety symbols is to attract your
attention to possible dangers. The safety symbols and
the explanations with them, deserve your careful
attention and understanding. The safety warnings do
not by themselves eliminate any danger. The
instructions or warnings they give are not substitutes
for proper accident prevention measures.
WARNING: For Your Safety!
Highlights instructions which failure to obey can result
in personal injury.
NOTE: Advises of information which maybe use-
ful while performing maintenance or repair of the
equipment. Also highlights instructions which fail-
ure to obey can result in damage to parts or equip-
ment.
WARNING: Spring Under Tension!
The rope starter on these engines contains a flat wire
spring that is under tension. Wear eye and hand
protection when replacing worn or broken spring, in
case it should uncoil as it is handled. Allow spring
tension to be completely relieved and make sure
pulley disengages from spring before removing the
pulley retainer(s), pulley, and starter spring from
housing.
WARNING: Electrical Shock!
Never touch electrical wires or components while the
engine is running. They can be sources of electrical
shock.
WARNING: Hot Surfaces!
The muffler, cylinder, crankcase, trimmer cutting head,
and other engine surfaces get extremely hot from
operation. These surfaces remain hot for a short
period of time after the engine is stopped. To prevent
severe burns, allow the engine to cool completely
before servicing.
WARNING: Explosive Fuel!
Gasoline may be present in the fuel tank, carburetor,
fuel lines, or crankcase. Gasoline is extremely flamma-
ble and its vapors can explode if ignited. Keep
sparks, flames, and other sources of ignition away
from the engine. Do not smoke while servicing the
engine. Never use gasoline as a cleaning agent.
Store gasoline only in approved containers, in well-
ventilated, unoccupied buildings, away from sparks,
flames, or other sources of ignition. Do not fill the fuel
tank while the engine is hot or running, since spilled
fuel could ignite if it comes in contact with hot parts or
sparks from ignition. Do not start the engine near
spilled fuel. Do not smoke while handling gasoline or
filling the fuel tank.
WARNING: Cracked or Broken Cooling Fins
Are A Hazard!
Be careful not to crack or break any cooling fins. They
could fly off during operation. If cooling fins are
cracked or broken, replace the flywheel.
