11. MAINTENANCE
CAUTION! Before cleaning, inspecting or repairing the saw it is required that the engine
should be turned off and cold and the glow plug removed in order to prevent inadvertent start.
Maintenance after each use
Air filter:
Loosen the nut and remove the air filter lid. Remove the filter element and brush away any
dust deposits. If the filter element is clogged by dust, split it into two parts and wash them in
petrol. If you are using compressed air, blow from inside. (fig. 27)
Lubrication hole:
Please remove the bar and check the lubrication hole continuity. (fig. 28)
Guide:
Once the bar is removed, please clear the dust from grooves and lubrication hole. (fig. 29)
Lubricate the pinion hub at the front of the bar through the lubrication hole. When assembling
the two parts, please press the hem
until it clicks. (fig. 30)

Pinion (3) (fig. 30)
Other parts:
Please check for possible oil leaks, loose covers and damage to the main sections, mainly
at the mounting points of handle and bar. Any problems that are found must be fixed before
further use of the saw.
Points of regular maintenance
Cylinder ribwork:
Dust deposits on the cylinder ribwork causes the engine to overheat. Regularly check and
clean the cylinder ribwork. The air filter and the cylinder head cover must be removed before
this action. When reassembling the cover, the wiring with bushings must be positioned
correctly. (fig. 31)
Note: Make sure that the air inlet holes are clean.
Spark plug (fig. 32):
If necessary, clean the electrodes with a wire brush and adjust the gap between them to
0,65 mm.
Geared pinion (fig. 33):
Check the pinion for flaws and excessive wear caused by the chain. Replace the pinion if the
wear is high. Never use a new chain together with a worn pinion or vice versa.
