DIRECTIONS FOR USE
BASIC SAFETY MEASURES
To use the outboard motor you must have all requisites
provided by law (physical suitability, insurance, government
duties, registration, and so on). We suggest you become
familiar with your boat equipped with SELVA motor in places,
which are not too crowded.
Taking some medicines, alcoholic drinks or drugs increase
considerably the risk of accidents.
Make sure that you are in a physical condition suitable for
driving. Pay attention to tiredness and sleepiness.
The engine operator should not let his mind wander, or be
distracted or influenced by other people, things or actions,(do
not smoke, eat, read, and so on.) while steering the boat.
Use fuels and oils suitable for the engine, which are listed in
the "greasing chart ".
Check every so often the oil level and the fuel level.
Stop the motor before every kind of maintenance or cleaning
procedures, and in case of complicated maintenance take the
spark-plug cap out. Picture No. 2.
Before opening the top cowling, wait till the engine has cooled
down.
Do not open the top cowling, when the engine is running.
Picture No. 3.

PAY ATTENTION TO THE PROPELLER
The propeller is certainly the least protected part of your motor.
It is therefore forbidden to get near the propeller when this is in
rotating. You must leave bathers, skiers and other boat users
enough space to move, in order to avoid any contact with the
propeller. Picture No. 4.
The engine operator must attach the engine stop switch
lanyard to his wrist when the motor is on. Picture No. 5.
Never sit on the motor. Picture No. 6.
Never change the inclination angle of your motor using the
steering rod, but use the proper handle.
Picture No. 7.
The motor must always have its top cowling on, when it is
operating
Picture-No. 8.
When you connect the fuel joint, check the proper connection.
Picture No. 9.
When starting there must be nobody within the engine
operator's action radius. Picture No. 10.
There must be nobody within the motor steering radius.
Picture No. 11.
The free lock lever must always be engaged while the motor is
in motion.
Never tilt-up the motor out of the water, while it is in motion.
Picture No. 12.
Never pull the recoil starter handle, while the motor is running.
Picture No. 13.
To transport the motor use only the proper handle.
Before transporting the motor you have to tilt-up the steering
rod properly.
The fuel tank is also provided with a handle to use for the
transport. Picture No. 14.
When starting or operating the engine, do not touch electrical
parts and particularly the ignition-coil, the high voltage wire, the
spark-plug cap and the spark-plug itself.
When opening the safety valve of the fuel tank, highly
flammable vapours come out. Do not smoke, inhale or use
open flames close to it.

If the motor has had an accident, you should have it fully
checked, before you use it again. If necessary let the SELVA
MARINE authorised skilled staff have a look at it.
Do not use the motor, if the damage could have compromised
the sailing safety.
Any alteration attempted on your motor or the removal of any
of its basic elements, can compromise its safety and it is
besides against the law, and anyway it means the immediate
loss of your guarantee.
Observe the laws in force.
Pay great attention to the weather conditions. Listen to the
weather forecast and take the warnings to the sailors into
consideration.
Keep your boat and equipment on board in a perfect state of
efficiency.
Keep enough spare parts on board.
Inform somebody of your route, before sailing.
Prevent fires and explosions.
Before operating an outboard motor, you must know the laws
and regulations relating to navigation.
Avoid sudden and dangerous manoeuvres
SELVA motors are only meant as propulsion for pleasure craft.
SELVA joint-stock CO. declines all responsibility for any
damage to items or harm done to any person, which is due to
an improper use of the motor.
