Air Filter
Component parts in correct sequence
Erratic idling behavior; poor acceleration
Idle setting too lean; turn low speed adjusting screw (2)
counterclockwise until engine runs and accelerates
smoothly.
Exhaust smokes at idle speed
Idle speed setting too rich; turn low speed adjusting
screw (2) clockwise until engine speed drops. Then turn
screw back one quarter turn and check that engine still
accelerates smoothly when you open the throttle.
The purpose of an air filter is to prevent any dust and dirt
in the intake air from entering the carburetor and thus
protect the moving parts of the engine from abnormal
wear. Dirty air filters reduce engine power, increase fuel
consumption and make starting more difficult.
A correction at the low speed adjusting screw usually
necessitates a change in the setting of the idle speed
adjusting screw (3).
The air filter must, therefore, be cleaned or replaced
when there is a noticeable loss of engine power.
Apart from minor adjustments, you should leave all carbu-
retor setting and repair work to your STIHL dealer. STIHL
dealers have trained staff and all the necessary servicing
tools and equipment.
Before removing the air filter, close the choke (turn rotary
knob in direction of arrow) to prevent dirt falling into the
carburetor. Remove the screw (1) and take off the filter
cover (2) and the filter (3)
Wash the filter (3) in a fresh, non-inflammable cleaning
solution and allow to dry.
Never refit a damaged filter element, always fit a new one.
