Control of air filter
A dirty air filter will reduce the air flow to the
combustion chamber and thereby the capacity of the
motor.
If the motor is operated without an air filter or with a
damaged air filter, will make it possible for dirt to get
into the motor, which will result in heavy wearing and
breakdown.
The air filter is to be cleaned as follows:
1.
Slacken the nut (A) for the air filter guard and
remove the guard(B).
2.
Remove grass and other large particles with the
hand.
3.
Slacken and remove the wing screw (C.) for the
air filter (D).
4.
Pull the foam filter (E) off the paper filter.
5.
Inspect both filters (E and D) and replace, if they are damaged.
6.
Clean both filters, if they are to be used again.
The filters must always be changed as stated in the service manual.
Clean the paper filter through striking it lightly with a hard object so that dirt falls out of the
element or through blowing compressed air of maximum 30 psi through the filter element from
the inside out.
Never try to brush the dirt off because this will force the dirt into the fibres of the filter.
Clean the foam filter element in warm soapy water and then rinse and dry it thoroughly. Dip the
filter element in clean motor oil and then press any surplus oil out.
The motor will smoke if there is too much oil in the foam.
Mount the filter again after cleaning in the reverse order to the above description.
