After Start
1. When the engine has started, the RPM should be 900-1000 RPM when idling.
2. Check the oil pressure. Normally this should be 2-4.5 bar. With cold engine the RPM should be kept down so that the oil
pressure does not exceed 4.5 bar. When idling at warm engine the oil pressure must not be below 1 bar.
3. Immediately after start the oil pressure warning lamp should go out. During normal operation the lamp should stay off.
4. Make sure that the charging control lamp goes out after the engine has started.
5. Check the cooling water temperature frequently. The temperature should be in the area of 70 – 95
o
C when engine is
warm.
Manoeuvering
1. With the control lever in central position the engine is idling, and the
marine gear is in neutral (pos. 0). When the lever is moved forward in
range 1, the marine gear is engaged to "Ahead” first, and then in range
2 the engine R.P.M. is increased. When the lever is moved from the
central position to range 3, the marine gear is engaged to "Astern”
first, and then in range 4 the engine R.P.M. is increased.
2. Only engage "Ahead” or "Astern” when the engine is idling.
3. To accelerate engine without engaging gear, operate gear release
button 5 and move control handle in either direction.
4. Increase the load gradually from idling in the course of the first 15-20
minutes shortly after the start of the engine.
Stopping the engine
1. Reduce the load gradually in the course of 15-20 minutes before stop.
2. Reduce the engine to idling and put the gear in neutral position.
3. Push the ”Stop” button (or pull the mechanical stop handle) until engine stops.
4. Move the ”Off/Run” switch to the ”Off” position.
5. Turn off the battery main switch.
Running in
To secure long life and maximum power it is recommended to run the engine for the first 25 hours at not more than 80 pct. of
the maximum output (about 3200 r.p.m.)
You should avoid slow hauling as for instance towage. After the first 25 hours it is recommended to change engine and gear
oil and to tighten up the cylinder head and to check or to possibly adjust the tension of the V-belt. Besides, it is
recommended to let an authorized service dealer go over engine and installation.
MAINTENANCE
Belt for alternator
To be adjusted every 150 hours by turning the alternator round the centres of
suspension. Tensioning should be so as to allow 8 - 10 mm deflection of the belt
under firm thumb pressure.
Air inlet filter
This is a wire gauze filter to be rinsed in petrol and cleaned by a blast of
compressed air after 300 hours' operating.
Fuel filter
A fuel filter is fitted between the fuel lift pump and the H.P. fuel pump. The filter is
a disposable one which cannot be cleaned. It should be changed every 300
operating hours or if water contamination is suspected.
Change the filter as follows:
1. Drain off the fuel from the filter by slackening drain screw A in the bottom of the
filter casing B.
2. Remove by hand or by means of a pair of tongs the filter casing and discard it.
3. Clean the sealing surface of the filter holder C if necessary.
4. Fill the new filter casing with clean fuel through the holes at the top of same.
5. Screw on the filter casing and tighten it by hand about half a turn after the
gasket fits tightly.
6. After changing the filter, bleed the fuel system as stated under ”Preparation for
first start”
