How to start the engine

Cautions:

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

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 is fitted with an automatic cold starting device for normal conditions of operation. Diesel engines need an extra cold starting aid if they are to start in very cold conditions. Normally, your vehicle or your machine will be fitted with the correct equipment for your region of operation.

Perkins engines can be equipped with various cold starting systems. The New 1000 Series is fitted with either a fuelled starting aid or port heaters as standard equipment:

Fuelled starting aid

An electrically operated device which ignites a specific amount of diesel fuel in the induction manifold in order to heat the induction air.

Port heaters

These electrical devices are fitted in the induction manifold and heat the induction air. They are operated automatically when the starter motor is engaged. When these devices are fitted, the start procedure for a cold engine is the same as that given for a cold engine start without starting aids.

If the engine is fitted with a cold starting device which is not fitted as standard equipment by Perkins engines, refer to the application Users Handbook or the instructions given by the manufacturer of the cold starting device, before starting the engine.

Examples of cold starting devices which are not fitted as standard equipment by Perkins engines are listed below:

Start pilot

Caution: Start Pilot equipment must not be used with heater type starting aids such as the fuelled starting aid.

A hand pump is used to inject a cold start fluid into the induction manifold through an atomiser. The cold start fluid ignites at a lower temperature than diesel fuel. The cold start fluid is contained in a separate reservoir. Certain models use a push button to actuate a solenoid which releases the cold start fluid from an aerosol container.

KBi

Caution: KBi equipment must not be used with heater type cold starting aids such as the fuelled starting aid.

This system uses an aerosol container filled with a cold start fluid. The fluid is released by a solenoid, which is operated by a push button. The cold start fluid is sprayed into the induction manifold through a nozzle. The cold start fluid ignites at a lower temperature than diesel fuel.

How to start a warm engine

1. If the engine is equipped with a manual stop control, ensure that it is in the "Run" position.
2. Adjust the engine speed control to the quarter open position.
3. Turn the start key to the "S" or "HS" position (A) or (B) to engage the starter motor.
4. Allow the start key to return to the "R" position, as soon as the engine starts.

Always ensure that the engine and starter motor are stationary before the starter motor is engaged again.

How to start a cold engine without starting aids

1. If the engine is equipped with a manual stop control, ensure that it is in the "Run" position.
2. Adjust the engine speed control to the maximum speed position.
3. Turn the start key to the "S" position (A) to engage the starter motor. Allow the key to return to the "R" position, when the engine starts. Then adjust the engine speed control to get an even idle speed.
4. If the engine does not start in 30 seconds, allow the start key to the "R" position for another 30 seconds. Then engage the starter motor again for a maximum period of 30 seconds.

How to start a cold engine with the fuelled starting aid

Caution: Ether type fuels must not be used at the same time as a fuelled starting aid.

1. If the engine is equipped with a manual stop control, ensure that it is in the "Run" position.
2. Turn the start key to the "H" position (A) and keep it there for 15 seconds.
3. Adjust the engine speed control to the maximum speed position.
4. Turn the start key to the "HS" position in order to engage the starter motor. Allow the start key to return to the "R" position, when the engine starts. Then adjust the engine speed control to give an even idle speed.
5. If the engine does not start in 15 seconds, turn the start key to the "H" position and hold it there for 10 seconds. Then engage the starter motor again.
