SECTION 1 – Safety Precautions

1. General

NOTICE:

NEVER PERMIT ANYONE TO OPERATE THE ENGINE WITHOUT PROPER

TRAINING.

It is the responsibility of the installer/operator to ensure that the finished installation complies
with CE Marking, the relevant Health & Safety requirements and the recreational craft
directive before commissioning.
Ensure that the engine battery isolator switch is in the off position and the key removed from
the control panel before carrying out any maintenance or repairs.

2. Lifting

DANGER:

CRUSH HAZARD! NEVER STAND UNDER A HOISTED ENGINE. IF THE HOIST

MECHANISM FAILS, THE ENGINE WILL FALL ON YOU, CAUSING SERIOUS INJURY

OR DEATH.

The Lifting points supplied with the engine are for lifting the engine/gearbox only. A suitable
spreader bar must be employed to prevent over-stressing either bracket during any lift.

3. Rotating Shafts and Belts

WARNING:

SEVERE HAZARD! KEEP HANDS AND OTHER BODY PARTS AWAY FROM

MOVING/ROTATING PARTS. WEAR TIGHT FITTING CLOTHING AND KEEP YOUR

HAIR SHORT OR TIE BACK. REMOVE ALL JEWELLERY BEFORE COMMENCING

WORK. CHECK BEFORE STARTING THE ENGINE THAT ANY TOOLS OR RAGS

USED DURING MAINTENANCE HAVE BEEN REMOVED FROM THE AREA.

RDG603A24 – Issue 13

Page 10 of 44

The engine and its accessories are not intended to be put into operation until they are
integrated into the boat as a whole. No person should be in the engine compartment and the
engine cover or deck hatches should be closed whilst the engine is running.

4. Exhaust System

WARNING:

EXHAUST HAZARD! NEVER OPERATE ENGINE IN A BOATS ENGINE BAY

WITHOUT PROPER VENTILATION. NEVER BLOCK VENTS OR OTHER MEANS OF

VENTILATION. ALL COMBUSTION ENGINES CREATE CARBON MONOXIDE GAS

DURING OPERATION. ACCUMULATION OF THIS GAS COULD CAUSE ILLNESS OR

EVEN DEATH.

WARNING:

BURN HAZARD! WAIT UNTIL THE EXHAUST COOLS BEFORE YOU TOUCH IT.

Exhaust gases may have temperatures as high as 650°C and contain elements which are
harmful if ingested.
It is therefore essential that exhaust systems are gas tight and lagged to prevent accidental
burning and inhalation of exhaust gases when inside the boat cabin.

5. Launching and Lifting Boats

Care must be taken when launching or craning new boats into or out of the waterway, so that
water does not enter the engine via the exhaust system or air vents. It is recommended that
these are blocked temporarily whilst undertaking this procedure.

6. Batteries

DANGER:

EXPLOSION HAZARD! NEVER SHORT OUT THE BATTERY TERMINALS,

INCLUDING WHEN CHECKING THE REMAINING BATTERY CHARGE THIS WILL

RESULT IN A SPARK AND MAY CAUSE AN EXPLOSION OR FIRE.

RDG603A24 – Issue 13

Page 11 of 44

WARNING:

BURN HAZARD! BATTERIES CONTAIN SULPHURIC ACID. NEVER ALLOW

BATTERY FLUID TO COME IN CONTACT WITH SKIN, EYES OR CLOTHING. SEVERE

BURNS COULD RESULT. MAKE SURE THE CORRECT PERSONAL PROTECTION

EQUIPMENT IS WORN.

 Batteries can produce explosive gases; keep sparks and flames away from the battery.

NO SMOKING

 Batteries contain sulphuric acid; if splashed on skin or eyes, flush well with water and

seek medical advice.

 Keep battery tops and battery compartment ventilated at all times
 If disconnecting the battery; remove the earth lead FIRST; and re-connect it last.
 If charging the battery; ensure that the charger is switched off before connecting and

disconnecting.
