GENERAL PRECAUTIONS
- Ensure that the engine is securely mounted.
- Ensure that the ventilation and combustion air ducts are not
obstructed.
- Keep the engine and surrounding areas clean.
- Never allow any part of the body to come into contact with
high pressure fuel oil when testing injection equipment.
- Avoid contact with exhaust pipe when the engine is, or has
recently been running. These parts can be very hot and can
cause severe burns.
- Rectify all fuel, water and oil leaks as soon as possible.
- Isolate the battery when working on the engine.
- All drive belts must receive regular attention.
- Keep electrical contacts free from corrosion etc by smearing
them with petroleum jelly.
- Batteries under charge release explosive gases, therefore
the battery compartment must be well ventilated at all
times. Never allow any smoking, sparks or flames near the
batteries.
- Wear protective goggles when handling liquids which are
harmful to the eyes, for ex. battery acid. If any of these
substances are splashed in the eyes, wash out thoroughly
with clean water.
- Many liquids used in engines are harmful if taken
internally.
In the event of accidentally swallowing oil, fuel, anti-
freeze or battery acid obtain medical assistance
immediately.

INTRODUCTION
The SABB-L-DIESEL, types L2.093LB, L3.139LB, L4.186LB is based
upon the LISTER PETTER engine types LPW2, LPW3 AND LPW4
and adapted for life boat propulsion conforming to the latest
requirements incl. SOLAS 1974, 1983 AMENDMENTS.
It is essential that the operators read carefully the main
points in this manual before the engine is put into service.
Reference is made to:
"CHECKS BEFORE STARTING", "STARTING", "OPERATION" and "STOP".
The engine must be able to start and operate under the most
severe conditions. Therefore the engine must be carefully
maintained in accordance with this manual.
The engine should be started and tested at regular intervals
according to the rules for lifeboat engines.
The information, specifications, illustrations, instructions
and statements contained within this publication are given
with our best intentions and are believed to be correct at the
time going to press. Our policy is one of continued
development and we reserve the right to amend any technical
information with or without prior notice.
Whilst every effort is made to ensure the accuracy of the
particulars contained within this publication neither the
Manufacturer, Distributor or Dealer shall in any circumstances
be held liable for any inaccuracy or the consequences thereof.
Users of this book are advised that the specification details
apply to a range of engines and not to any one particular
engine. In cases of difficulty consult SABB MOTOR A.S,
BERGEN, NORWAY or a local SABB MOTOR or Lister-Petter
Distributor for further advice and technical assistance.
The information given is subject to the Company's current
Conditions of Tender and Sale, and is for the assistance of
users and is based upon results obtained from tests carried
out at the place of manufacture. This company does not
guarantee that the same results will be obtained elsewhere
under different conditions.
When purchasing parts or giving instructions for repairs
customers should, in their own interests, always specify
GENUINE SABB MOTOR A.S PARTS.
Parts that have not been supplied by the SABB MOTOR A.S cannot
be relied upon for correct material, dimensions or finish.
This Company cannot therefore be responsible for any damage
arising from the use of such parts and the guarantee will be
invalidated.

FUEL SYSTEM
Fuel Pump Timing........18ΕBTDC
Injector Settings.......New:/Used 240 bars
Fuel Specification......Gas oil conforming BS2869:1970
Class A1 or A2 or to USA Specification
ASTM D-975-77 Grades No. 1-D and 2-D
If the engine has to work in areas with extremely low ambient
temperatures, use fuel with good clog characteristic. Clog
point (CFPP) -25ΕC
EXCESS FUEL DEVICE.
This device is fitted as standard, being automatically
selected when the engine is intentionally stopped.
Should the engine run out of fuel and stop, the device will
not select excess fuel until the engine mounted stop lever is
moved to the stop position by pressing the stop button and
releasing it.
The engine will automatically disengage the excess fuel
position when the engine runs up to speed.
LUBRICATION SYSTEM
Lub. Oil Pressure........Min. 1.0 bar at idle. Min. 2,5 bar at
3000 rpm
Oil Sump Capacity........L2.093: 3,2 litres

An anti-freeze concentration of 40 % should be used as an all
year round coolant. This concentration will give low
temperature protection down to -25ΕC.
Additionally, a 40% concentration will protect the cooling
system from corrosion.

10
WARNING: Anti-freeze contains Monoethylene Glycol and other
constituents which are toxic if taken internally, and can be
absorbed in toxic amounts under prolonged skin contact.
If clothing is splashed with anti-freeze, it should be washed
before being worn again.
If anti-freeze is swallowed accidentally, medical advice
should be sought immediately.

ENGINE BLOCK HEATER
According to Det Norske Veritas' rules of 1986 for lifeboat
engines, the engine shall start easily at -25ΕC, and an
engine block heater is part of the equipment.
The engine heater should always be energised in environments
where the temperature is -15Εor lower.
The engine heater is 300 W and the voltage is 42 V.
An externally mounted thermostat controls the heater element
and is preset to open the electric circuit below 0Εand close
above +13ΕC ambient temperature.
If the engine is built in compliance with SOLAS 1973
Regulations, the minimum cold start requirement is -15ΕC.
For those engines, engine block heater does not belong to
standard equipment, but may be fitted.
