Extra fuel filter 

 

 

If an extra fuel filter is fitted together with a 
water separator, check the transparent 
bowl to see if there is any water in the fuel. 
If necessary, drain the filter via the cock in 
the bottom of the bowl. 

Try to avoid fuel splash. Pump up the fuel 
with the hand primer and vent the system. 
The fuel filter element should be changed 
at least once a season. 

FUEL STRAINER

 

 

The fuel pump on the engine has a built-in 
strainer which is accessible after removing 
the cover. Clean the strainer at least once 
a season. 

Immediately after starting the engine, 
check for leakage. 

Always vent the fuel system. See under 
“Venting the fuel system”. 

 

Injector 

The injector should be removed once a season and handed in to a diesel shop for 
cleaning and checking the opening pressure, the spray pattern and for leakage. To 
remove the injector, unscrew the delivery pipe and the by-pass oil line. Fit protective caps 
over the openings. 

Release both the nuts over the fork holding the injector to the cylinder head and lift up the 
injector. If the injector feels stiff to remove due to gumming, grip it with, e.g., polygrip 
pliers and carefully rotate it back and forth while levering it up at the same time (with a 
screwdriver, e.g., under the fork(. Before fitting, check to make sure the contact surface 
on the injector and copper sleeve is clean. Connect up the delivery pipe and the return 
line but do not tighten the delivery pipe nut at the injector. Turn over the engine with the 
starter motor until fuel comes from the delivery pipe. Tighten up the delivery pipe nut and 
make sure the delivery pipe cone is fitted properly. Concerning tightening torque, see 
“Technical Data”.
