Important information

Serious risk of injury

When working on the engine, for example when adjusting drive belts and the clutch, or when changing the

oil, it is important not to start the engine. The engine could be damaged, but more importantly there is a

serious risk of injury.

Therefore, block the starting device and switch off the manual fuel cock when working on the engine. This

is especially important if the engine has a remote starter or automatic starting.

WARNING!

This warning symbol and text can be found next to those maintenance items where it is particularly impor-

tant to bear in mind the risk of injury.

Introduction

This Operator's manual describes the operation

and maintenance of Scania industrial engines.

The engines are liquid-cooled Otto gas engines

with turbochargers.

The engines are available with different power

settings. Engine power for the engine ordered is

indicated on a plate located on the engine control

unit.

Note:

Only standard components are described in the

operator's manual. Information about special

equipment is contained in instructions from the

various manufacturers.

To ensure the maximum performance and the

longest service life for the engine remember the

following:

• Read through the Operator's manual before

starting to use the engine. Even regular users

of Scania engines will get new information

from the Operator's manual.

• Always follow the maintenance instructions.

• Read the section on safety carefully.

• Get to know your engine so that you know

what it can do and how it works.

• Always contact an authorised Scania work-

shop for maintenance and repairs.

The information in this Operator's manual was

correct at the time of going to press. Scania re-

serves the right to make alterations without prior

notice.

Note:

Always use spare parts that are approved by Sca-

nia for maintenance and repairs.

Power classes

OPM 320 en-GB 5

Power classes

Scania supplies engines in two different power classes:

PRP, Prime power: Intended for continuous use and an unlimited number of operational hours with vary-

ing loads. The average load factor must not exceed 70% of the rated power in a 24-hour period. Accumu-

lated overload 110% for one hour per 12-hour period. This power class applies to single-speed engines.

COP, Continuous power: Intended for continual use with a non-varying load and an unlimited number of

operational hours.

The engine serial numbers and power classes for the engines that are used in this installation should be listed

Environment and safety

Environmental responsibility

Scania develops and produces engines that are as

environmentally-friendly as possible. Scania has

made major investments in the reduction of

harmful exhaust emissions in order to fulfil the

environmental requirements in force in almost

every market.

At the same time, we have been able to maintain

a high level of performance and operating econ-

omy for Scania engines. To maintain these

throughout the entire service life of the engine, it

is important for the user to follow the instruc-

tions on running, maintenance and fuel, lubricat-

ing oil and coolant as outlined in the Operator's

manual.

Other green initiatives taken include ensuring

that, following maintenance and repair, waste

that is harmful to the environment (for example

oil, coolant, filters and batteries) is disposed of

accordance with the applicable environmental

requirements.

Safety

The following pages contain a summary of the

safety precautions to be complied with when op-

erating and maintaining Scania engines. The

equivalent text can also be found under the rele-

vant maintenance item.

To prevent damage to the engine and personal in-

jury, and to ensure that it runs optimally, follow

the instructions in the warnings and advisories.

If the instructions are not followed, the warranty

can cease to apply.

Different types of advisory

Warning!

All advisories preceded by Warning! are very

important. They warn of serious faults and incor-

rect operation that could lead to personal injury.

Example:

WARNING!

Block the starting device and switch off the man-

ual fuel cock when working on the engine. If the

engine starts unexpectedly, there is a serious risk

of injury.

Important!

Advisories preceded by Important! warn of

faults and incorrect operation that could lead to

equipment being damaged. Example:

IMPORTANT!

An excessive coolant temperature can cause en-

gine damage.

Note:

Advisories preceded by Note: refer to informa-

tion important to ensure the best possible opera-

tion and functionality. Example:

Note:

you check the oil level.

OPM 320 en-GB 7

Environment and safety

Environment

This Operator’s manual contains specially high-

lighted text with instructions to help protect the

environment during maintenance. Example:

Environment

Use a suitable container. Used coolant must be

disposed of as specified in national and interna-

tional laws and regulations.

Warnings and advisories

Fuel

The engine is designed and optimised to be run

on either natural gas or pure biogas.

WARNING!

Natural gas and pure biogas mainly consist of

methane, and may have a methane content of up

to 97%. Methane is flammable and must be han-

dled with great care.

WARNING!

Methane is not toxic, but in a mixture of 50 per

cent or more with air, the oxygen content will be

so low that the risk of suffocation increases.

IMPORTANT!

Comply with applicable local laws and regula-

tions when handling natural gas and pure biogas.

Methane is a highly flammable gas which is

flammable when present in a 5-16% mixture in

the air.

Methane can even be ignited by static electricity

from a person.

Methane ignites when in contact with hot surfac-

es at approx. 580°C.

Methane burns with an almost invisible flame.

Therefore, take extra care.

Methane is lighter than air and therefore rises in

the event of leakage. Bear this in mind if leaks do

occur in enclosed spaces such as indoors or in a

tunnel. In those cases the gas can cause suffoca-

tion and an explosive atmosphere.

Smoking

WARNING!

Smoking is prohibited in the vicinity of gas en-

gines.

OPM 320 en-GB 8

Environment and safety

Safety precautions for running the

engine

Daily maintenance

Always carry out a visual inspection of the en-

gine and engine compartment before starting the

engine or when the engine has been switched off

after operation.

This inspection should be done to detect fuel, oil

or coolant leaks, or anything else that may re-

quire corrective action.

Fuel

WARNING!

Fuel of the wrong quality can cause malfunctions

or cause the engine to stop. This can cause dam-

age to the engine and, possibly, personal injury.

REQUIREMENT!

Use only fuel which fulfils the requirements in

the Quality requirements for fuel section.

Hazardous gases

WARNING!

Only start the engine in a well-ventilated area.

The exhaust gases contain carbon monoxide and

nitrogen oxides, which are toxic.

When the engine is run in an enclosed space,

there must be effective devices to extract gas and

exhaust gases.

Starter lock

IMPORTANT!

If the instrument panel is not fitted with a starter

lock, the engine compartment should be locked

to prevent unauthorised personnel from starting

the engine. Alternatively, a lockable master

switch or battery master switch can be used.

Running

WARNING!

The engine must not be run in environments

where there is a risk of explosion, as all of the

electrical or mechanical components can gener-

ate sparks.

Approaching a running engine always poses a

safety risk. Parts of the body, clothes or dropped

tools can get caught in rotating parts such as the

fan and cause injury. For personal safety all ro-

tating parts and hot surfaces must be fitted with

guards.

OPM 320 en-GB 9

Environment and safety

Safety precautions for handling ma-

terials

Lubricating oil

WARNING!

All lubricants and many chemicals are flamma-

ble. Always follow the instructions on the rele-

vant packaging.

The work must be carried out on a cold engine.

Spillage on hot surfaces can cause fires.

Store used rags and other flammable materials

safely so as to avoid spontaneous combustion.

Batteries

WARNING!

The batteries contain and form oxyhydrogen gas,

particularly during charging. Oxyhydrogen gas

is flammable and highly explosive.

There must be no smoking, naked flames or

sparks near the batteries or the battery compart-

ment. Incorrect connection of a battery cable or

jump lead can cause a spark, which can cause the

battery to explode.

Chemicals

WARNING!

Most chemicals such as glycol, anti-corrosive

agents, preservative oils and degreasing agents,

are hazardous to health. Some chemicals, such as

preservative oil, are also flammable. Always fol-

low the safety precautions on the packaging.

Store chemicals and other materials which are

hazardous to health in approved and clearly

marked containers, where they are inaccessible

to unauthorised persons.

Environment

Excess and used chemicals must be disposed of

as specified in national and international laws

and regulations.

OPM 320 en-GB 10

Environment and safety

Safety precautions for maintenance

Switch off the engine

WARNING!

Working on a running engine always poses a

safety risk. Parts of the body, clothes or dropped

tools can get caught in rotating parts and cause

injury.

Always switch off the engine before carrying out

maintenance, unless otherwise indicated.

Make it impossible to start the engine: Remove

any starter key, or cut the power using the main

power switch or battery master switch and lock

them.

Hot surfaces and fluids

WARNING!

There is always a risk of sustaining burns when

an engine is hot. Particularly hot parts are engine

manifolds, turbochargers, oil sumps, as well as

hot coolant and oil in pipes and hoses.

Lubrication system

WARNING!

Hot oil can cause burns and skin irritation. Wear

protective gloves and goggles when changing

hot oil.

Make sure that there is no pressure in the lubri-

cation system before starting work on it.

Make sure that the oil filler cover is fitted when

starting and running in order to avoid oil escap-

ing.

Environment

Used oil must be disposed of as specified in na-

tional and international laws and regulations.

OPM 320 en-GB 11

Environment and safety

Cooling system

WARNING!

Never open the coolant filler cap when the en-

gine is hot. Hot coolant and steam may spray out

and cause burns. If the cap has to be opened do it

slowly to release the pressure before removing

the cap. Wear protective gloves as the coolant is

still very hot.

Avoid skin contact with coolant as this may

cause irritation to the skin. Wear protective gog-

gles and gloves when handling coolant.

Ethylene glycol can be fatal if ingested.

Environment

Used coolant must be disposed of as specified in

national and international laws and regulations.

Fuel system

WARNING!

Natural gas and pure biogas are extremely flam-

mable and can even be ignited by static electric-

ity from a person.

Natural gas and pure biogas are lighter than air

and therefore rise in the event of leakage. Be

aware of if there is a leak in a confined space. In

those cases the gas can cause suffocation and an

explosive atmosphere.

Always use Scania spare parts for the fuel and

electrical systems. Scania spare parts are de-

signed to minimise the risk of fire and explosion.

IMPORTANT!

Work on the engine may only be carried out by

personnel who are aware of the risks and have

sufficient knowledge of natural gas and pure bi-

ogas.

Comply with applicable local laws and regula-

tions when handling natural gas and pure biogas.

The operator is responsible for using the correct

type of gas to ensure that local laws are complied

with.

Environment and safety

OPM 320 en-GB 12

Before working on the engine, ensure that the

gas content of the air is below 10% of the lower

explosive limit (LEL). Also check the permitted

gas content with reference to local laws and reg-

ulations.

When working on the engine, use warning plates

indicating that work with flammable fuel is in

progress. Warning signs should be written in the

local language. Comply with local regulations on

the design of warning signs. An example of the

design of a warning sign is shown in the illustra-

tion.

Inform all personnel of the basic risks of natural

gas and pure biogas.

Check the grounding of the engine where open

handling of gas takes place, i.e. handling which

may give rise to an explosive atmosphere.

Never attempt to put out a burning gas flame. Try

to stop the flow of gas instead. Move material

that could be ignited by the flame.

Electrical system

WARNING!

Before working on the electrical system, ensure

that the gas content of the air is below 10% of the

lower explosive limit (LEL). Also check the per-

mitted gas content with reference to local laws

and regulations.

Switch off the engine and switch off the power

by disconnecting the electrical cables to the bat-

tery. External power supplies to extra equipment

in the engine must also be disconnected.

Always use Scania spare parts for the fuel and

electrical systems. Scania spare parts are de-

signed to minimise the risk of fire and explosion.

WARNING!

Before welding, ensure that the gas content of

the air is below 10% of the lower explosive limit

(LEL). Also check the permitted gas content

with reference to local laws and regulations.

When carrying out welding work on and near the

engine, disconnect the battery and alternator

electrical cables. Pull out the multi-pin connector

for the engine control unit as well.

Connect the welding clamp close to the compo-

nent to be welded. The welding clamp must not

be connected to the engine, or so that the current

can cross a bearing.

When welding is finished:

1. Connect the alternator and control unit ca-

bles.

2. Connect the batteries.

Batteries

WARNING!

The batteries contain highly corrosive sulphuric

acid. Take care to protect your eyes, skin and

clothes when charging or handling batteries.

Wear protective gloves and goggles.

If sulphuric acid comes in contact with the skin:

Wash with soap and plenty of water. If it gets in

your eyes: Rinse immediately with plenty of wa-

ter and seek medical attention.

WARNING!

Cut the power by disconnecting the electrical ca-

bles to the battery and not to the engine, as there

is a risk of sparks building up.

Environment

Used batteries must be disposed of as specified

in national and international laws and regula-

tions.

Before starting

WARNING!

Ensure that all guards are in place before starting

the engine. Ensure that no tools or other objects

have been left on the engine.

The air filter must be fitted before starting the en-

gine. Otherwise there is a risk of objects being

sucked into the compressor impeller or of injury

if you come into contact with the air filter.

Starting and running

Checks before first start

Before the engine is started for the first time, car-

ry out the maintenance items listed under First

start in the maintenance schedule. Check the fol-

lowing:

• Oil level.

• Coolant.

• Fluid level in batteries.

• State of battery charge.

• Condition of the drive belt.

See also Maintenance interval

.

Checks before running

WARNING!

Block the starting device and switch off the man-

ual fuel cock when working on the engine. If the

engine starts unexpectedly, there is a serious risk

of injury.

Carry out daily maintenance as described in the

maintenance schedule prior to operation. See

Maintenance interval

.

Starting the engine

WARNING!

Only start the engine in a well-ventilated area.

When the engine is run in an enclosed space,

there must be effective devices to extract gas and

exhaust gases.

IMPORTANT!

The starter motor must only be cranked twice for

30 seconds at a time. After that, it must rest for at

least 5 minutes before the next attempt to start it.

1. Open the manual fuel cock.

2. Disconnect the engine from any load.

3. If the engine has a battery master switch:

Connect the power using the battery master

switch.

4. Start the engine.

5. The engine will rev up. Let the engine run

without load for 2 minutes.

Starting at low temperatures

Take the local environmental requirements into

account. Use the engine heater to avoid starting

difficulties. Scania recommends that an engine

heater should be used if the engine will be used

at temperatures below -10°C.

A low engine speed and moderate load on a cold

engine gives better combustion and faster heat-

ing than warming up with no load.

Avoid running it longer than necessary at idling

speed.

OPM 320 en-GB 18

Starting and running

Running

Check instruments and warning lamps at regular

intervals.

Engine speed range

The engine operating speed range is between low

idling and the nominal engine speed. The nomi-

nal engine speed is 1,500 or 1,800 rpm. Low

idling is normally 1,000 rpm.

Driving at high altitude

When driving at high altitudes engine power is

reduced automatically due to the lower oxygen

content in the air. It is then not possible to run the

engine at maximum power.

Note:

Driving at a height higher than 2,000 metres

above sea level is only permitted if it has first

been approved by Scania.

Coolant temperature

IMPORTANT!

An excessive coolant temperature can cause en-

gine damage.

Normal coolant temperature during operation is

90-95°C (194-203°F).

Alarm levels are set in the engine control unit.

The default setting for the lowest and highest

limit values for high coolant temperature are

98°C (208°F) and 105°C (221°F) respectively.

The high coolant temperature alarm has the fol-

lowing functions:

• Alarm at the lowest limit value.

• Alarm at the lowest limit value and engine

shutdown at the highest limit value.

The engine is designed and optimised for contin-

uous operation at 100% load. To ensure opera-

tional reliability and to extend the maintenance

intervals, the following limitations for load and

operating time apply:

The accumulated total engine operating time at

less than 25% load should be < 5%.

The accumulated total engine operating time of

the engine at less than 40% load should be

<15%.

Oil pressure

For information on the normal oil pressure and

lowest permitted oil pressure, see the Technical

data section.

The engine management system activates an

alarm for high or low oil pressure at engine

speeds above 650 rpm. The values below are for

overpressure, not absolute pressure.

• An alarm for high oil pressure is activated

when the pressure exceeds 7.9 bar (115 psi).

• An alarm for low oil pressure is activated

when the oil pressure drops below 0.65 bar

(9 psi).

The incorrect oil pressure alarm has the follow-

ing functions:

• Alarm only.

• Alarm and engine shutdown.

Note:

High oil pressure (above 6 bar/87 psi) is normal

if the engine is cold when started.

Output at 100% PRP Max. operating time

0-25% load 30 minutes

25-40% load 120 minutes

More than 40% load No restrictions.

OPM 320 en-GB 19

Starting and running

Charge air temperature

The engine management system has the follow-

ing alarm levels for high charge air temperature.

• Alarm at 70 C (158°F).

• Alarm or engine shutdown at 80°C (176°F).

Charging indicator lamp

If the lamp comes on during operation: Check

and adjust the alternator drive belt according to

the section Checking the drive belt

.

If the charging indicator lamp is still on, this

could be due to an alternator fault or a fault in the

electrical system.

Belt transmission

When the belt transmission is new, it may make

a squeaking noise when running. This noise is

normal and disappears after 50-100 hours of op-

eration. The noise does not affect the service life

of the belt transmission.

Engine shutdown

IMPORTANT!

There is risk of post boiling and of damage to the

turbocharger if the engine is switched off with-

out cooling. The power must not be switched off

before the engine has stopped.

1. Run the engine without load for 3 minutes at

the nominal engine speed.

2. Switch off the engine via the coordinator and

allow the engine to run until the gas has run

out and the engine stops.

3. Close the manual fuel cock.

Checks after running

WARNING!

Block the starting device and switch off the man-

ual fuel cock when working on the engine. If the

engine starts unexpectedly, there is a serious risk

There is always a risk of sustaining burns when

an engine is hot. Particularly hot parts are turbo-

chargers, oil sumps, hot coolant and oil in pipes

and hoses.

IMPORTANT!

Check the coolant level following the first start.

Top up with coolant as necessary.

1. Check that the manual fuel cock is turned off.

2. Check that the power supply has been cut.

3. Check that the cooling system contains

enough glycol according to the Scania in-

structions. See the section Coolant

.

4. If the temperature is below 0°C (32°F): Pre-

pare for the next start by connecting the en-

gine heater (if fitted).
