gaskets. Check that the rubber damper is not damaged.
Fit the exhaust elbow and the gearbox. Use new ELECTRICAL SYSTEM
IMPORTANT
The following applies to engines fitted with alternators:
1.
Do not break the electrical circuit between the
alternator and the battery when the engine is running.
If a main switch is fitted it must therefore not be
turned off until the engine is stopped.
No lead must be disconnected when the engine is
running since this can irreparably damage the charging
regulator.
2.
The battery, battery cable and cable terminals are to be
checked regularly. The battery poles are to be properly
clean and the cable terminals are to be tight and well
greased so that a break in the circuit cannot occur. All
other cables are to be properly connected, no loose
connections must occur. The battery’s positive and
negative connections must on no condition be exchanged
when the battery is connected.
3.
When starting with an auxiliary battery, check first that it
has the same rated voltage as the standard battery.
Connect the auxiliary battery with positive to positive and
negative to negative. Remove the auxiliary battery when
the engine has started. Notel The cables to the standard
battery must on no condition be disconnected.
BLEEDING THE FUEL SYSTEM
94.
Fuel system bleeding is always carried out in the
following cases: When the microfilter is changed - when
draining via the drain plug - when cleaning the gauze in the
fuel pump - when the fuel tank has run dry - when fitting an
injector pump - after leaks in or repairs on, the fuel piping -
when the engine has been out of use for a long time.
Bleeding is carried out as follows:
Open the air bleed screw 1 in the microfilter. Pump up fuel
using the hand pump 2 until clean air-free fuel runs out.
Close the air bleed screw. If the pump effect is poor rotate
the engine until the pump’s drive cam assumes another
position. If the injector pump has been dismantled or, when
the engine is to be started for the first time after renovation,
4.
5.
When carrying out electrical welding on the engine or
associated installation parts the charging regulator’s
cable must be disconnected and insulated first. After-
wards both the battery cable terminals can be removed.
When carrying out repairs on the generator, both battery
cable terminals must always be disconnected. The same
applies if the battery is given a quick charge.
the injection pump must be bled. Open the air bleed screw 3 6. Never test a connection with a screwdriver or similar tool
on the injection pump. Pump the hand pump 2 until air-free
fuel runs out. Loosen the pressure connection 4 and rotate
the engine with the starter motor until fuel runs out from the
pressure pipe. Tighten the pressure connection and start the
engine.
