BEFORE OPERATING THE ENGINE
1. Before operating a new engine it should be thoroughly inspected to ensure that
during transit and installation it has not suffered damage likely to affect its
subsequent operation. Controls and instruments should be studied carefully in
order that their functions are thoroughly understood.
2. Check that the radiator (where applicable) is full and top off as necessary --
Refer to "Cooling System" on page 28 for recommended coolant mixtures.
3. In the case of marine/industrial engines, ensure that there is coolant in the
degas/expansion tank (where applicable).
CAUTION: Under no circumstances may the engine be started without liquid
in the cooling system.
4. Check the engine oil level and top up or fill as necessary -- Refer to "Check
Engine Oil Level" on page 24. For the correct type and grade of oil -- Refer to
"Recommended Lubricants" on page 22.
5. Ensure that the battery is fully charged and, if necessary, top up with distilled
water.
NOTE: Ensure that ALL wiring ground connections are properly made to a clean
point on the chassis/frame.
6. The engine must be started in accordance with the starting instructions -- Refer
to "STARTING THE ENGINE" on page 15.
OPERATING CONTROLS
Ignition or Isolation Switch
An ignition or isolation switch is usually fitted which connects the engine starter
motor and other electrical equipment to the battery. The switch can be moved to
any of the four positions shown by rotating the key. These positions are:
Auxiliary Circuits
1. Auxiliary Circuits - When moved to this position the auxiliary electrical
equipment such as radios and heater fans, can be operated without also
connecting the starting circuit with the battery.
2. Off - When set to this position, the switch disconnects the auxiliary electrical
equipment and the starting circuit from the battery. The key can be removed
from the switch when it is in this position; this will help to prevent unauthorized
operation of the engine.
3. Run - This switch position connects the auxiliary circuits as described
previously, and the alternator is given initial excitation via the battery.
