Maintenance of the muffler and exhaust system
Depending on the used fuel, oil and a mixture ratio, silencer and exhaust system can accumulate nagar or soot. This may cause
a decrease in performance of the device. In order to restore the previous performance you should submit the device to manufac-
turer's authorized service.
Replacing the cutting line (XVII)
Unscrew the cover spool from the grass trimmer spindle. At the same time press both lock buttons on spool housing and pull out
the spool from its cover. Remove the remnants of old cutting line from the spool. Spool, spool CAP, spring and mounting screw
should be clean up with remnants of grass, earth, and other contaminations.
Prepare a section of line with the diameter and length given in the technical data table. In the middle of the length, put the line
through the gap between two parts of the spool. Reel the line on both parts of the spool in a counterclockwise direction. Behind
the gaps you should leave about 15 cm of the line which should be put through the holes in the housing. Close the spool in its
housing.
Mount the spool with cutting line in accordance with the procedure described in point "Preparing the grass trimmer for operation"
Storing the grass trimmer
Proper maintenance before storage will allow for long trouble-free operation of the grass trimmer
Before storing the grass trimmer for an extended period of time, you should empty the tank and the system of the fuel.
Check the condition of the fuel system for leaks. If you find them, remove them before
storage. To do this, you should submit the grass trimmer to an authorized service center.
Drain the tank with fuel, by means, for example, of a plastic fuel pump that is commercially available.
Start the engine and let it idle until it shuts down. This will clean the carburetor of remaining fuel. Allow to cool down the engine.
Remove the spark plug. Through the opening pour one teaspoon of oil for two-stroke engines. Several times, carefully draw
starter line, it will distribute the oil in combustion chamber. Install the spark plug.
Clean the grass trimmer from the remnants of grass, soil and other contaminants. The device should be stored in a cool, dry place
with good ventilation, away from sources of ignition. The device should be stored in a dry, closed place protected from access by
unauthorized persons, especially children.
