1. SAFETY
SAFETY INFORMATION
For your safety and the safety of
others, pay special attention to these
precautions.
Operator Responsibility
• TOHATSU outboard motor is
designed to give safe and
dependable service if
operated according to
instructions.
Read and understand the
Owner’s Manual before
operating the outboard motor.
Failure to do so could result in
personal injury or equipment
damage.
• Gasoline is harmful or fatal if
swallowed. Keep the fuel tank
out of reach of children.
• Gasoline is extremely
flammable and is explosive
under certain conditions.
Refuel in a well-ventilated area
with the engine stopped.
• Do not smoke or allow flames or
sparks where the engine is
refueled or where gasoline is
stored.
• Do not overfill the fuel tank.
After refueling make sure that
the fuel tank cap is closed
properly and securely.
• Be careful not to spill any fuel
while refueling. Spilled fuel or
fuel vapor may ignite. If any
fuel is spilled make sure that the
area is dry before starting the
engine.

8
SAFETY
• Know how to stop the engine
quickly in case of emergency.
Understand the use of all controls.
• Do not exceed the boat
manufacturer’s power
recommendation, and be sure that
the outboard motor is properly
mounted.
• Never permit anyone to operate the
outboard motor without proper
instruction.
• Before operating the outboard
motor, familiarize yourself with all
laws and regulations relating to
boating and the use of outboard
motors.
• Do not attempt to modify the
outboard motor.
• Always wear a life-jacket when on
board.
• Do not operate the outboard motor
without the engine cover. Exposed
moving parts can cause injury.
• Do not remove any guards, labels,
shields, covers or safety devices;
they are installed for your safety.
• Stop the engine immediately if
anyone falls overboard.
• Do not run the engine while the
boat is near anyone in the water.
• Attach the emergency stop switch
lanyard securely to the operator.
• Shift to the neutral position
and then shift to the reverse
position at low engine speed.
Do not shift to the reverse
position suddenly at high engine
speed.
• Moving parts can injure
you. Install the engine
cover after emergency
starting the engine. Do not
operate the outboard motor
without the engine cover.

9
SAFETY
Fire and Burn Hazards
Gasoline is extremely flammable, and
gasoline vapor can explode. Use
extreme care when handling gasoline.
KEEP OUT OF REACH OF
CHILDREN.
• Remove the fuel tank from the boat
for refueling.
•Refuel in a well-ventilated area
with the engine stopped. Keep
flames and sparks away, and do not
smoke in the area.
• Refuel carefully to avoid spilling
fuel. Avoid overfilling the fuel tank
(there should be no fuel in the filler
neck). After refueling, tighten the
fuel filler cap securely. If any fuel
is spilled, make sure the area is dry
before starting the engine.
The engine and exhaust system
become very hot during operation and
remain hot for a while after
stopping. Contact with hot engine
components can cause burns and may
ignite some materials.
• Avoid touching a hot engine or
exhaust system.
• Allow the engine to cool before
performing maintenance or
transporting.
Carbon Monoxide Poisoning
Hazard
Exhaust contains poisonous carbon
monoxide, a colorless and odorless
gas. Breathing exhaust can cause loss
of consciousness and may lead to
death.
• If you run the engine in an area that
is confined, or even partially
enclosed, the air can become
contaminated with a dangerous
amount of exhaust gas. To keep
exhaust gas from building up,
provide adequate ventilation.
