Safety precautions

These safety precautions are important.

You must refer also to the local regulations in the country of use. Some items only apply to specific

applications.

!   Only use these engines in the type of application for which they have been designed.

!   Do not change the specification of the engine.

!   Do not smoke when you put fuel in the tank.

!   Clean away fuel which has been spilt. Material which has been contaminated by fuel must be moved to a

safe place.

!   Do not put fuel in the tank while the engine runs (unless it is absolutely necessary).

!   Do not clean, add lubricating oil, or adjust the engine while it runs (unless you have had the correct training;

even then extreme caution must be used to prevent injury).

!   Do not make adjustments that you do not understand.

!   Ensure that the engine does not run in a location where it can cause a concentration of toxic emissions.

!   Other persons must be kept at a safe distance while the engine or auxiliary equipment is in operation.

!   Do not permit loose clothing or long hair near moving parts.

!   Keep away from moving parts during engine operation.

Warning! Some moving parts cannot be seen clearly while the engine runs.

!   Do not operate the engine if a safety guard has been removed.

!   Do not remove the filler cap or any component of the cooling system while the engine is hot and while the

coolant is under pressure, because dangerous hot coolant can be discharged.

!   Do not use salt water or any other coolant which can cause corrosion in the closed coolant circuit.

!   Do not allow sparks or fire near the batteries (especially when the batteries are on charge) because the

gases from the electrolyte are highly flammable. The battery fluid is dangerous to the skin and especially

to the eyes.

!   Disconnect the battery terminals before a repair is made to the electrical system.

!   Only one person must control the engine.

!   Ensure that the engine is operated only from the control panel or from the operator's position. Discard used

lubricating oil in a safe place to prevent contamination.

!   Ensure that the control lever of the transmission drive is in the "out-of-drive" position before the engine is

started.

!   The combustible material of some components of the engine (for example certain seals) can become

extremely dangerous if it is burned. Never allow this burnt material to come into contact with the skin or with

the eyes.

!   Diesel fuel and lubricating oil (especially used lubricating oil) can damage the skin of certain persons.

Protect your hands with gloves or a special solution to protect the skin.

!   Do not wear clothing which is contaminated by lubricating oil. Do not put material which is contaminated

with oil into the pockets of clothing.

!   Discard used lubricating oil in accordance with local regulations to prevent contamination.

!   Use extreme care if emergency repairs must be made in adverse conditions.

!   Always use a safety cage to protect the operator when a component is to be pressure tested in a container

of water. Fit safety wires to secure the plugs which seal the hose connections of a component which is to

be pressure tested.

!   Do not allow compressed air to contact your skin. If compressed air enters your skin, obtain medical help

immediately.

!   Turbochargers operate at high speed and at high temperatures. Keep fingers, tools and debris away from

the inlet and outlet ports of the turbocharger and prevent contact with hot surfaces.

!   The fuel injector units of this engine are controlled electronically by a pulse of 110 volts.

!   The fuel injector units are actuated by high-pressure engine lubricating oil. Do not remove any component

of the high-pressure system while the engine oil is under pressure, because dangerous oil can be

discharged.

!   Fit only genuine Perkins parts.

How to care for your engine

This handbook has been written to assist you to maintain and operate your engine correctly.

To obtain the best performance and the longest life from your engine, you must ensure that the maintenance

operations are done at the intervals indicated in "Preventive maintenance". If the engine works in a very dusty

environment or other adverse conditions, certain maintenance intervals will have to be reduced. Renew the

filter canisters and lubricating oil regularly in order to ensure that the inside of your engine remains clean.

Ensure that all adjustments and repairs are done by personnel who have had the correct training. Perkins

distributors have this type of personnel available. Parts and service can also be obtained from a Perkins

distributor.

The terms "left side" and "right side" apply when the engine is seen from the flywheel end.

Warning! Read the "Safety precautions" on page 2 and remember them. They are given for your protection

and must be applied at all times.

Engine preservation

Introduction

The recommendations indicated below are designed to prevent damage to the engine when it is withdrawn

from service for a prolonged period. Use these procedures after the engine is withdrawn from service. The

instructions for the use of POWERPART products are given on the outside of each container.

Procedure

Caution: The procedure for this engine is different to the procedure for other Perkins engines, because of the

design of the fuel injection units.

1  Completely clean the outside of the engine.

2  Operate the engine until it is warm. Stop the engine and drain the lubricating oil from the sump. Ensure that

the oil gallery of the high-pressure lubrication system is drained.

Caution: If the gallery is not drained, the engine cylinders will be filled with engine lubricating oil when the fuel

injector units are removed.

3  Disconnect the battery.

4  Disconnect the air inlet pipe at the rocker cover. Release the setscrews and remove the rocker cover. Spray

POWERPART Lay-Up 2 around the rocker shaft assembly and into the induction ports in the cylinder head, as

indicated on the container label.

5  Drain the fuel supply gallery, fitted to the cylinder head.

Caution: If the gallery is not drained, the engine cylinders will be filled with fuel when the fuel injector units are

removed.

6  Remove the fuel injector units, see the Workshop Manual, and spray POWERPART Lay-Up 2 for one to two

seconds into each cylinder bore with the piston at bottom dead centre.

7  Slowly turn the crankshaft one revolution and then fit the fuel injector units, complete with new seat washers.

8  Fit the rocker cover and connect the air inlet pipe.

9  Renew the canister of the lubricating oil filter, see "How to renew the canister of the lubricating oil filter" on

page 26.

10  Fill the sump to the full mark on the dipstick with new and clean lubricating oil and add POWERPART Lay-

up 2 to the oil to protect the engine against corrosion. If POWERPART Lay-Up 2 is not available, use a correct

preservative fluid instead of the lubricating oil. If a preservative fluid is used, this must be drained and the

lubricating oil sump must be filled to the correct level with normal lubricating oil at the end of the storage period.

11  Drain the coolant circuit, see "How to drain the cooling system" on page 19. In order to protect the cooling

system against corrosion, fill it with an approved antifreeze mixture because this gives protection against

corrosion.

Caution: If protection against frost is not necessary and a corrosion inhibitor is to be used, it is recommended

that you consult the Technical Service Department, Perkins Engines Company Limited, Peterborough.

12  Connect the battery, eliminate air from the fuel system. Operate the engine for a short period in order to

circulate the lubricating oil and the coolant in the engine. Then correct leakages of fuel, lubricating oil or air.

13  Disconnect the battery. Then put the battery into safe storage in a fully charged condition. Before the

battery is put into storage, protect its terminals against corrosion. POWERPART Lay-Up 3 can be used on the

terminals.

14  Remove the air filter. Then, if necessary, remove the pipe(s) installed between the air filter and the

turbocharger. Seal the air inlet to the turbocharger with waterproof tape.

Peregrine EDi, Models WL, WN, WQ and WS

15  Remove the exhaust pipe. Spray POWERPART Lay-Up 2 into the exhaust manifold or the turbocharger.

It is recommended that the spray time for the turbocharger is 50% longer than the spray time for the manifold,

which is indicated on the container label. Seal the manifold or the turbocharger with waterproof tape.

16  Clean the engine breather pipe and seal the end of the pipe.

17  When a preservative fuel is to be used, drain the fuel system and fill it with the preservative fuel.

POWERPART Lay-Up 1 can be added to the normal fuel to change it to a preservative fuel. If preservative fuel

is not used, the system can be completely filled with normal fuel but the fuel must be drained and discarded at

the end of the storage period together with the fuel filter canister.

18  Remove the drive belts and put them into storage.

19  Seal the vent pipe of the fuel tank or the fuel filler cap with waterproof tape.

20  In order to prevent corrosion, spray the engine with POWERPART Lay-Up 3. Do not spray the area inside

the alternator cooling fan.

If the engine protection is done correctly according to the above recommendations, no corrosion damage will

normally occur. Perkins are not responsible for damage which may occur when an engine is in storage after a

period in service.

How to start the engine

Temperature of 15 °C (60 °F) to -20 °C (-4 °F)

Several factors affect engine start, for example:

!   The power of the batteries

!   The performance of the starter motor

!   The viscosity of the lubricating oil

!   The installation of a cold start system

The engine will start without a cold starting aid at temperatures as low as -20 °C (-4 °F). In conditions where

the temperature is lower than this, an ether start system may be necessary.

Before the engine is started the operator should understand fully the reason for the controls and their use.

Before the engine is started:

!   Check that there is sufficient coolant and, if necessary, add the correct coolant, see Chapter 4, Preventive

maintenance.

!   Check that there is sufficient lubricating oil in the sump and, if necessary, add lubricating oil. See Chapter

4, Preventive maintenance. Ensure that the lubricating oil is of the correct grade for the ambient conditions.

!   Fill the fuel tank with fuel of the correct specification, see Chapter 5, Engine fluids.

!   Check the air filter and its connections.

!   Ensure that all of the electrical connections are tight.

Notes:

!   See Chapter 5, Engine fluids for the correct engine fluids.

!   The procedures to start the engine may vary according to the application. If possible, consult the User's

Handbook for the application.

1  Apply the hand brake, if the application is fitted with one. Ensure that the transmission is in the out-of-drive

position. Ensure that the engine speed control is in the minimum speed position.

2  Turn the start key to the "ON" position.

Note: Do not operate the engine speed control during engine start, the management system controls the

supply of fuel, and it will ignore signals from the speed control until the engine starts.

3  Turn the start key further to engage the starter motor. If the application has a start button, press and hold

the button.

4  Release the start key (or the button) as soon as the engine starts. The start key will return to the "ON"

position.

Caution: If the engine does not start within 30 seconds, release the start key and wait two to three minutes to

allow the starter motor to cool. If after three tries the engine does not start, turn the key to the "OFF" position.

When the engine starts, check that the lubricating oil pressure exceeds 138 kPa (20 lbs/in ) 1,4 kgf/cm   within

the first 10 seconds, see "Engine data" on page 10 for the correct lubricating oil pressure. If a gauge is not

fitted, check that the warning light for low oil pressure is extinguished. If this does not occur, stop the engine

and find and correct the fault. Allow the engine to warm at approximately 1000 rev/min for three to five minutes

before load is applied.

Starting aid

The engine electronics system provides cold start ability down to -20 °C (-4 °F). If it is necessary to start the

engine at an ambient temperature less than this, the customer must provide a suitable cold start system.

How to stop the engine

Turn the engine start key to the "OFF" position.

It is recommended that the engine is operated at idle speed for three to five minutes before the engine is

stopped. This will allow the lubricating oil and the coolant to carry the heat away from large ferrous

components.

Adjustment of engine speed range

The idle or maximum speed settings cannot be changed by the engine operator.

Engine operation at idle speed

Do not operate the engine for long periods at idle speed as this could have an adverse affect on the engine

performance or damage the engine.

Running-in

A gradual running-in of a new engine is not necessary. Prolonged operation at light loads during the early life

of the engine is not recommended.

Maximum load can be applied to a new engine as soon as the engine is put into service and the coolant

temperature has reached a minimum of 76 °C (170 °F).

!   Do not operate the engine at high speeds without a load

!   Do not overload the engine.

Altitude

The engine management system will automatically compensate for altitude.

Preventive maintenance periods

These preventive maintenance periods apply to average conditions of operation. Check the periods given by

the manufacturer of the equipment in which the engine is installed. Use the periods that are shortest. When

the operation of the engine must conform to the local regulations these periods and procedures may need to

be adapted to ensure correct operation of the engine.

It is good preventive maintenance to check for leakage and loose fasteners at each service.

These maintenance periods apply only to engines that are operated with fuel and lubricating oil which conform

to the specifications given in this handbook.

How to eliminate air from the fuel system

If air enters the fuel system, it must be eliminated before the engine can be started.

Air can enter the system if:

!   The fuel tank is drained during normal operation.

!   The low-pressure fuel pipes are disconnected.

!   A part of the low-pressure fuel system leaks during engine operation.

In order to eliminate air from the fuel system, proceed as follows:

1  Loosen the vent plug (A1) on the top of the fuel filter head.

2  Operate the plunger of the fuel priming pump (A2) until fuel, free from air, comes from the filter vent point.

Tighten the vent plug.

3  Turn the start key to the "ON" position.

4  Operate the starter motor for intervals of 15 seconds until the engine starts. If the engine runs correctly for

a short time and then stops or runs roughly, check for air in the fuel system. If there is air in the fuel system,

there is probably a leak in the low pressure system. Turn the start key to the "OFF" position to stop the engine.

Correct the leakage and repeat the procedure.

Fuel specification

To get the correct power and performance from your engine, use good quality fuel. The recommended fuel

specification for Perkins engines is indicated below:

Cetane number

Viscosity

50 minimum

2.0/4.5 centistokes at 40 °C

0,835/0,855 kg/litre

0.2% of mass, maximum

85% at 350 °C

Density

Sulphur

Distillation

Cetane number indicates ignition performance. A fuel with a low cetane number can cause cold start problems

and affect combustion.

Viscosity is the resistance to flow and engine performance can be affected if it is outside the limits.

Density: A lower density reduces engine power, a higher density increases engine power and exhaust smoke.

Sulphur: A high sulphur content (not normally found in Europe, North America or Australasia) can cause

engine wear. Where only high sulphur fuels are available, it is necessary to renew the lubricating oil more

frequently, see "Lubricating oil specification" on page 32.

Distillation: This is an indication of the mixture of different hydrocarbons in the fuel. A high ratio of light-weight

hydrocarbons can affect the combustion characteristics.

Low temperature fuels

Special winter fuels may be available for engine operation at temperatures below 0 °C. These fuels have a

lower viscosity and also limit the wax formation in the fuel at low temperatures. If wax formation occurs, this

could stop the fuel flow through the filter.

If you need advice on adjustments to an engine setting or to the lubricating oil change periods which may be

necessary because of the standard of the available fuel, consult the Technical Service Department of Perkins

International Limited at Peterborough or your nearest Perkins Distributor.

Aviation kerosene fuels

Cautions:

!   Do not use aviation kerosene fuel JP4. JP5 and JP8 can be used, but they can affect engine performance

and wear in the fuel injector units could increase. It is recommended that you consult the Technical Service

Department of Perkins International Limited at Peterborough if aviation kerosene fuel is to be used.

!   Aviation kerosene fuels are more flammable than diesel fuel and need careful storage and careful

management.

Caution: The type of lubricating oil to be used may be affected by the quality of the fuel which is available. For

further details see "Fuel specification" on page 31.

Always ensure that the correct viscosity grade of lubricating oil is used for the ambient temperature range in

Coolant specification

The quality of the coolant which is used can have a great effect on the efficiency and life of the cooling system.

The recommendations indicated below can help to maintain a good cooling system and to protect it against

frost and / or corrosion.

If the correct procedures are not used, Perkins cannot be held responsible for frost or corrosion damage.

1  If it is possible, use clean soft water in the coolant.

2  If an antifreeze mixture, other than Perkins POWERPART, is used to prevent frost damage, it must have an

ethanediol base (ethylene glycol) with a corrosion inhibitor. It is recommended that the corrosion inhibitor is of

the sodium nitrite / sodium molybdate type. The antifreeze mixture must be an efficient coolant at all ambient

temperatures and it must provide protection against corrosion. It must also have a specification at least as

good as the requirements of either BS6580 or MOD AL39.

Perkins POWERPART antifreeze exceeds the requirements of the above standard.

The quality of the antifreeze coolant must be checked at least once a year, for example, at the beginning of

the cold period. The coolant must be renewed every two years.

The antifreeze mixture must consist of equal quantities of antifreeze and water. Concentrations of more than

50% of antifreeze must not be used because these can affect adversely the performance of the coolant.

3  When frost protection is not necessary, it is still an advantage to use an approved antifreeze mixture

because this gives a protection against corrosion and also raises the boiling point of the coolant. If an approved

antifreeze mixture is not available, add a correct mixture of corrosion inhibitor to the water.

All Peregrine EDi engines are supplied with a coolant filter / conditioner canister. Renew the coolant and the

filter / conditioner canister in accordance with the maintenance "Schedules" on page 18.
