FUEL FILTER
Dismantle the filler cap and pull out the section
holding the filler cap in position when fuelling.
Catch the fuel hose with the help of tool
502 50 83-01.
Pull out the fuel filter. Slide back the metal weight
and pull off the hose.
Check that the filter is not cracked or in any other
way defective.
NOTE! Fouled filters must not be cleaned but
replaced with a new one.
If the filter is heavily fouled, this may be due to
the machine being filled with a contaminated fuel.
Drain the fuel and filter when refilling.
LEAKAGE TESTING
PRESSURE TESTER
Use the pressure tester 501 56 27-01 to test the
tightness of the fuel system.
The pressure tester is supplied with an adapter for
small hose sizes, this should be used on the fuel
hose. Make the hose between the adapter and the
pressure tester as short as possible.
Pump up the pressure to approximately 7 psi/50
kPa. A falling pressure indicates that the fuel hose
leaks, the connection to the carburettor leaks or
the carburettor is defective.
