Carburetor Adjustment; Routine Maintenance - Electrolux Trimmer Instruction Manual

Your machine can be equipped with a low emission
carburetor. We recommend that you have any
adjustment of the carburetor made exclusively by an
authorized service center, which disposes of special
equipment for ensuring the best performance with the
lowest emissions. To adjust the speed to the minimum,
turn the screw marked (T) as shown: With the engine
running and well warmed up, turn the screw (T) gently
clockwise, until the engine rotates at regular speed (stead
noise), without the cutting devices in motion. If the cutting
devices are moving, turn the screw (T) gently
counterclockwise until you obtain the proper adjustment.
Check periodically to see that all the screws in the
machine are securely fastened in place. Replace
damaged, worn, cracked or bent blades. Always make
sure the blade or nylon string head is correctly installed
and the nut holding the blade is tight.
L1. Cleaning the air filter
(At least every 25 hours of work). A clogged filter causes
alteration of the carburetor adjustment, reducing power
and increasing fuel consumption, as well as causing
difficulties in startup. Open the cover on the filter as
shown in the figure by pressing in the point indicated by
the arrow for release. Clean the inside of the filter housing
thoroughly (fig. L2). The filter can be cleaned using gentle
jets of compressed air. For more thorough cleaning it can
be washed in soapy water.
L3. Gearbox
Every 50 working hours add grease for high speed gears
in the gearbox, through the hole (C).
L4. Spark plug
Periodically (at least every 50 hours) remove and clean
the spark plug and set the space between the electrodes
(0.5/0.6 mm). Replace it if excessively encrusted or, in
any case, after 100 working hours. In case of excessive
CAUTION! Use only the recommended type of
nylon string. Do not use steel wires for any
reason, in order to prevent serious injury.
M1. String replacement (String head A)
(1) If, when you bump the nylon string head on the
ground, no more string comes out, it means there is none
left and you have to replace it. To replace the reel of
string, press both the release pawls indicated by the
arrows, remove the empty reel (2), unroll any string left
and rewind the new string. (3) Open the original package
of string and insert the ends of the two strings in the
eyelets on the reel, then wind the strings completely on
the reel in the same direction and fasten the end of each
string in the 2 opposite grooves. (4) Replace the reel in its
housing and thread the ends of the strings in their
bushings. Pull each string so that about 15 cm comes out

and take the filter out using a hook or long-nose pliers.
Periodically, every season, contact your service center
for general maintenance and cleaning of the inside. This
will reduce the possibility of unexpected problems and
will ensure the good performance and long life of your
machine.

M. Replacement of nylon string
on each side Reassemble the nylon string head as
shown. (5) Start the machine and repeat the procedures
described in the section "Supply of nylon string".
M2. String replacement (String head B)
(1) Loosen the locking nut on the base of the nylon head
by turning it clockwise.(2) Remove the base cover
assembly. Remove the empty spool from the housing and
discard any remaining line. (3) Prepare 2 lengths (8ft
each) of 2.4 mm nylon line. Thread 1 end of each line into
the two holes on opposite sides of the spool. Pinch the
exposed ends flat with a pair of pliers to prevent them
slipping through the hole.(4) Wind the two lines in the
same direction around the spool. (5) Slide the end of the
two lines into the grooves to hold the line temporarily. (6)
Position the spool back into the housing and pull the line
through the eyelets. (7) Pull about 15cm (6inch) of line out
on either side. (8) Reassemble the nylon string head as
CAUTION! All the above adjustments should be
made with the cutting devices correctly installed.
CAUTION! Start the brush cutter in a flat place.
During startup stand in a stable position. Make
sure the blade or nylon string head do not touch
the ground or any obstacles.
CAUTION! Regularly it is important, in order to
prevent the engine from overheating, to remove
the dust and dirt from the vents, the cylinder cover
and fins on the cylinder, using a wooden scraper.
CAUTION! In case of prolonged disuse, empty
the fuel tank and run the engine until it is out of
gas. Store the brush cutter in a dry place.
