Safety while working
Safety while working
To prevent an accident or injury and to pro-
vide quality service, observe the following
safety procedures.
Rotating part
• Hands, feet, hair, jewelry, clothing, personal
flotation device straps, and so on, can
become entangled with internal rotating
parts of the engine, resulting in serious
injury or death.
• Keep the top cowling installed whenever
possible. Do not remove or install the top
cowling when the engine is running.
• Only operate the engine with the top cowl-
ing removed according to the specific
instructions in the manual. Keep hands,
feet, hair, jewelry, clothing, personal flota-
tion device straps, and so on, away from
any exposed moving parts.
Hot part
During and after operation, engine parts are
hot enough to cause burns. Do not touch any
parts under the top cowling until the engine
has cooled.
Electric shock
Do not touch any electrical parts while start-
ing or operating the engine. Otherwise, shock
or electrocution could result.
Propeller
Do not hold the propeller with your hands
when loosening or tightening the propeller
nut.
Handling of gasoline
• Gasoline is highly flammable. Keep gaso-
line and all flammable products away from
heat, sparks, and open flames.
• Gasoline is poisonous and can cause injury
or death. Handle gasoline with care. Never
siphon gasoline by mouth. If you swallow
some gasoline, inhale a lot of gasoline
vapor, or get some gasoline in your eyes,
see your doctor immediately. If gasoline
spills on your skin, wash with soap and
water. If gasoline spills on your clothing,
change your clothes.
Ventilation
• Gasoline vapor and exhaust gas are
heavier than air and extremely poisonous. If
gasoline vapor or exhaust gas is inhaled in
large quantities, it may cause loss of con-
sciousness and death within a short time.
• When test running an engine indoors (for
example, in a water tank) make sure to do
so where adequate ventilation can be main-
tained.
