Safety Precautions - Beta Marine Beta 50 Operator's Maintenance Manual

Safety Precautions!

A Keep the engine, gearbox and surrounding area
clean, including the area immediately below the
engine.
B Drives - Power Take Off Areas
i) Gearbox Output Flange
The purpose of a marine diesel propulsion engine is to
provide motive power to propel a vessel. Accordingly
the gearbox output shaft rotates at between 280 and
2400 rev/min. This flange is designed to be coupled
to a propeller shaft by the installer and steps must be
taken to ensure adequate guarding.
ii) Forward End Drive
Engines are supplied with unguarded belt drives to
power the fresh water pump and battery charging
alternator. The installer must ensure that it is not
possible for injury to occur by allowing access to this
area of the engine. The three pulleys run at high speed
and can cause injury if personnel or clothing come in
contact with the belts or pulleys, when the engine is
running.
iii) Power Take Off Shaft (Engine Mounted Option)
Shaft extensions are available as an option and rotate
at between 850 and 3600 rev/min. If contact is made
with this shaft when the engine is running, injury can
occur.
C Exhaust Outlet
Diesel marine propulsion engines emit exhaust gases
at very high temperatures - around 400 - 550°C.
Engines are supplied with either wet exhaust outlet
(water injection bend) or dry outlet (dry exhaust
stub) - see option list. At the outlet next to the heat
exchanger/header tank, the exhaust outlet can
become very hot and if touched, can injure. This must
be lagged or avoided by ensuring adequate guarding.
It is the responsibility of the installer to lag the exhaust
system if a dry system is used. Exhaust gases are
harmful if ingested, the installer must therefore ensure
that exhaust pipes are led overboard and that leakage
in the vessel does not occur.
D Fuel
i) Fuel Lines
Diesel engines are equipped with high pressure fuel
injection pumps, if leakages occur, or if pipes fracture,
fuel at a high pressure can harm personnel. Skin must
be thoroughly cleaned in the event of contact with
diesel fuel.
ii) Fuel Supply Connections
Engines are supplied with 8mm compression fittings.
The installer must ensure that when connections are
made, they are clean and free of leaks.
E Oil
The Beta propulsion unit is supplied with 2 dipsticks,
one for the engine and one for the gearbox. Ensure
dipsticks are returned and secure after checking, if
not oil leaks can cause infection when touched. All oil
must be removed from the skin to prevent infection.
F Scalding
An engine running under load will have a closed circuit
fresh water temperature of 85° to 95°C. The pressure
cap on the top of the heat exchanger must not
be removed when the engine is running. It can
only be removed when the engine is stopped and has
cooled down.
G Transportation/Lifting
Engines are supplied on transportable pallets. Lifting
eyes on engines are used for lifting engine and
gearbox assembly only, not the pallet and associated
kit.
GENERAL DECLARATION
