4 If possible, allow the engine to run at no load for approximately three minutes. Run the engine at no load

until the water temperature gauge has started to rise. Check all gauges during the warm-up period.

How to start a cold engine in cold conditions

Refer to the Owner's Manual of the OEM for your type of controls. Use the procedure which follows to start the

engine.

Warning! Ether type fuels must not be used in the 2806-18 six cylinder engine.

The engine will start without aids down to a temperature of -10 °C (14 °F), but the ability to start at temperatures

below 10 °C (50 °F) will improve by the use of a cylinder block coolant heater or a device which heats the

crankcase oil. This will help to reduce white smoke and misfires when the engine is started in cold weather.

Note: If the engine has not been run for several weeks, fuel may have drained. Air may have moved into the

filter housing. Also, when fuel filters have been changed, some air will be left in the filter housing. Refer to "How

to eliminate air from the fuel system" on page 49.

1 Move the ignition switch to the ON position. If a system fault is indicated by, for example a panel light,

investigate the cause. If necessary use the Perkins Electronic Service Tool, EST.

2 Push the start button or turn the ignition switch to the START position to crank the engine.

3 If the engine fails to start within 30 seconds, release the start button or ignition switch. Wait for 30 seconds

to allow the starter motor to cool before attempting to start the engine again. Repeat for a maximum of three

times; if the engine fails to start investigate the cause,

4 A system fault may be indicated after the engine is started. If this occurs the ECM has detected a problem

with the system. Investigate the cause, if necessary use the Perkins service tool EST. Refer to the Diagnostic

Manual for more information on engine diagnostics.

Note: Oil pressure should rise within 15 seconds after the engine starts. The electronic engine controls monitor

the oil pressure and will stop the engine if the oil pressure is below normal.

5 If possible, allow the engine to run at no load for approximately three minutes. Run the engine at no load

until the coolant temperature gauge starts to rise. Check all gauges during the warm-up period.

Caution: The oil pressures and fuel pressures should be in the normal range on the instrument panel. Do not

apply a load to the engine until the oil pressure gauge indicates at least normal pressure. Inspect the engine

for leaks and/or unusual noises.

Important notes

The cold start strategy will be activated when the coolant temperature is below 17 °C (63 °F). The cold start

strategy will continue until the coolant temperature reaches 28 °C (82 °F), or until the engine has been running

for 14 minutes. A timer will disable the cold start strategy after a maximum time of 14 minutes.

If the cold start strategy is active and if the ECM measures engine speed, the engine power that is available is

reduced.

After the ECM has completed the cold mode (or the cold mode is disabled), it cannot be enabled again until

the ECM is switched OFF.

If an engine has been stopped, for example after a fault has been indicated, do not attempt to restart the engine

until it has fully stopped.
