OPERATION
Mechanical oil pressure control
It is necessary to reactivate the mechanical oil pressure control in the following cases:
- after the initial filling - first filling - of the fuel tank or if the tank has run dry.
- in the case of an automatic engine stop due to an inefficient engine oil supply.
- after freeing the engine when in presence of extremely low temperatures.
1. Fill up fuel tank.
2. Check engine oil level.
3. To activate depress hand lever „1“ for approx. 5 seconds.
4. Hold down pin „1“ during approx. 5 seconds in the case of encapsulated engine versions.
5. Simultaneously actuate hand lever a few times in the case of engines equipped with fuel pumps.
6. Complete engine. Check to see that encapsulating elements seal correctly.
☛
ATTENTION! Check oil level every 8 to 15 operating hours in spite of the mechanical oil pressure con-
trol.
Starting with external battery etc.
Observe the following connection sequence when using an external battery to start the engine:
1. Connect one end of jumper cable to positive terminal of auxiliary battery.
2. Connect the other end of jumper cable to positive terminal of the vibro plate battery.
3. Now connect jumper cable clamp to negative terminal of the auxiliary battery.
4. Connect other end of jumper cable to the upper mass of the vibratory plate, e.g. to the motor fixing screws.
The connection point should be as far away as possible from the battery of the vibratory plate.
5. Disconnect jumper cable in reserve order.
☛
ATTENTION! Only 12 V batteries may be used. The use of e.g. a 24 V truck battery will lead to an
explosion of the vibro plate battery!
Additional notes on starting at very low temperatures!
☛
ATTENTION! Never use starting sprays or similar - they are forbidden because they are dangerous.
Only use original Wacker crank.
☛
ATTENTION! If cranking, is too slow, the engine can start running in the opposite direction of rotation.
In this case the air is drawn in through the exhaust and the exhaust gases excape through
the air filter.
Risk of fire! Switch off engine and start it again.
In case of a manual start: Free the engine by turning it approximately 10 to 20 times with the decompression
lever in a central position. Then the engine is decompressed, but not ready to start. This intermediate position
is used to turn the engine "free" when at very low temperatures. The turning resistance becomes appreciably
lower owing to the change in viscosity of the oil film. At the same time you will hear that the nozzle of the fuel
injection system is injecting cleanly (rattling).
At very low temperatures (below -5
o
C, use the starting oil dosing device (23).
Note: Do not use more than 2 doses as otherwise there is a risk of crank back-swing.
