OPERATION AND MAINTENANCE
PREPARATION FOR STARTING
Check the coolant level with radiator.
Check the oil level in engine sump.
Check the fuel oil level in the tank
Check the battery is fully charged and that all electrical
connections are properly made and all circuits in order.
STARTING THE ENGINE
Turn starter switch in clockwise direction to the “ON”
position and then to start position
As soon as the engine starts, release the switch to the
“ON” position.
TO STOP THE ENGINE
1.Pull the stop control knob and hold until the engine
ceases to rotate.
2. Push and ensure the stop control knob returns to the
run position.
3. Turn start switch to the ‘Off’ position.
Note: Where an electrical shut off solenoid is provided,
turn the start key to “Off” position to stop engine.
Always be sure that the starter pinion has stopped
revolving before re-engaging the starter.
RUNNING-IN PROCEDURE
It is not necessary to gradually run-in a new engine and
any prolonged light load running during the early life of
the engine and in fact prove harmful to the bedding in
of piston rings and liners.
Full load can be applied on a new engine as soon as the
engine is used, provided that the engine coolant is first
allowed to reach a temperature of at least 140
o
F (60
o
C).
POST-DELIVERY CHECKOVER
After a customer has taken delivery of his diesel engine, it
is advisable, a general check-over of the engine be carried
out after the first 25 hours in service.
It is also recommended that the following procedure
be adopted where an engine has been laid up for a
considerable period before it is again put into service.
1.Drain lubricating oil sump and re-fill up to the full mark
on the dipstick with new clean oil (Do not overfill).
2. Renew the lubricating oil filter (canister).
3. Check external nuts for tightness.
4. Check/ adjust valve tip clearances to 0.15 mm (0.006’’
to inlet and exhaust valve in cold.
5. Check fuel pipes from tank to fuel injection pump for
leaks.
6. Check for lubricating oil leaks and rectify if necessary.
7. Check hose clips for tightness.
8. Check cooling system for leaks and inspect radiator
water level.
9. Check fan belt for tension.
10. Carry out test to check general performance of engine.
11. Check engine mounting bolts for tightness.
12. Check the electrical equipment such as rate of charge,
effectiveness of connections and circuits, etc.
Thereafter maintenance periods should be in accordance
with the instructions given. (Ref. Section E).
PRESERVATION OF LAID-UP ENGINES
It is recommended that the following procedure
be adopted and applied immediately the unit is
withdrawn from service:
1. Thoroughly clean all external parts of the engine.
2. Run the engine until well-warmed. Stop the engine
and drain lubricating oil from sump. Remove the oil filter.
3. Drain coolant from radiator and engine cylinder
block.
4. Replace the oil filter, fill sump to correct level
with clean, new lubricating oil or with a suitable
preservative fluid.
5. Remove atomisers and spray into cylinder bores
100 ml of lubricating oil divided between the
cylinders.
6. Turn engine slowly over compression and replace
atomisers.
7. Remove air cleaner intake pipe and Remove
exhaust pipe and seal opening in manifolds.
8. Disconnect battery and store in fully charged
condition. Before storing the battery, terminals
should be treated to prevent corrosion.
The fuel system be drained or charged with a suitable
preservative designed for the prevailing climatic
