Cleaning and care
Caution: Be especially careful when cleaning and caring
for the cutter (injury hazard!). Never touch the cutter with
bare hands. Always wear protective gloves!
Regularly check the cutter for damage and clean it with a sui-
table brush or cloth.
If after extended use cutting performance is no longer satis-
factory, the blade needs resharpening. Take it to a DOLMAR
service centre.

MAINTENANCE
General
CAUTION: Never do maintenance work near an open
flame. FIRE HAZARD!
CAUTION: Before doing any work on the trimmer,
always switch off the engine, pull the spark plug
cap (see Changing the spark plug) and wear protec-
tive gloves!
Do not attempt to repair a damaged cutter (bent,
broken)!
Clean the trimmer regularly and make sure all screw
fasteners are tight.
Adjusting the cutter slide play
CAUTION: Switch off the engine, pull the spark plug cap
and wear protective gloves!
The slide play needs adjustment when cuttings get stuck between
the blades or the play becomes excessive after extended use
through normal cutter wear.
Loosen nuts (1) one or two turns. Tighten screws (2) only slightly
(if necessary, loosen them beforehand).
Adjust all screws as follows: Loosen 1/4 turn and hold in this
position with screwdriver. Tighten nut (1).
NOTE: The play is correct when it is just possible to move
the disc under the screw head back and forth by hand. Then
lubricate the cutter with a few drops of oil.
Caution: If the play is insufficient, the cutter will heat up
and can become damaged.
Cleaning the air filter insert
- Push the tab (3) in the direction of the arrow and lift open
the air filter cover.
- Take out the foam filter insert.
Caution: To prevent eye injuries, do not blow dirt particles
out.
- If the insert is very dirty, wash it out with standard dishwas-
hing liquid.
- Clean it often if it gets very dirty. The engine can only develop
its full power with a clean filter insert.
- Before putting the insert back in, clean out the interior of
the air filter with a brush. Do not allow dirt particles to get
into the induction opening of the carburetor!
- Let the filter insert dry thoroughly and put it back in the
filter.
Caution: If the filter insert is damaged, replace it immedia-
tely! Torn bits of fabric and large dirt particles can destry
the engine.
