11.4.3 Cleaning the air filter
• The type of air filter depends on the engine brand and type.
• The air filter is located under the black protection cover next to the fuel reservoir on the
engine.
• Loosen the black protection cover.
• There are two types of filter. Besides the common sponge filter there is a filter that, as in an
automobile, consists of paper layers.
• Sponge filters can be cleaned by rinsing them with some petrol and blowing them with
compressed air.
• Paper filters are cleaned by dusting them down or treating them with compressed air.
• After cleaning, replace all parts in their original positions.
Caution:
In the event the machine has toppled over for some reason, check the air filter
immediately. The unusual position of the engine may have caused oil to seep
from the crankcase via the carburettor onto the air filter. Oil on the filter paper
obstructs the air passage. Soiled filters must be replaced immediately.
11.4.4 Grinding the blades
Sharp chipping blades will provide optimum performance and maximum operating speed. En-
hance your own work comfort by taking some time to check the blades, and if necessary, grind
them.
SHARP BLADES = MAXIMUM OUTPUT
For your information:
The blades need not be disassembled for grinding. Use a small right-angle
grinder equipped with a grinding disc that is suitable for steel.
Warning:
Always wear safety glasses and ear protection when grinding blades. Gloves
form part of the mandatory attire when performing maintenance.
