8.2.3. CHECK THE SPARK
The most common problems when starting a machine
are produced by a dirty spark plug or bad. Clean spark
plug and check it regularly. Check the electrode gap is
correct (0,6 - 0,7 mm).
8.2.4. CLEANING THE CYLINDER FINS
The fins of the cylinder are in charge of refrigerating
the engine thanks to these being in contact with the
air. These fins should always be clean and without any
material that prevents the air flow. If the fins are not
clean and blocked with dirt, the engine will overheat
and could even break. Check these fins on a regular
basis.
8.2.5. MOTOR VENTILATION DUCTS
Remove dirt from the ventilation ducts, so as not to
damage the engine and avoid a possible fire.
8.2.6. MAINTAINING THE CHAIN BAR
Reverse the mower bar every time you spend 10 fuel
tanks to prevent wear on only one side. The bar guide
should always keep his profile. Verify that it keeps the
thickness constant throughout the bar. Replace the
bar if necessary.
Check that there are no cracks and the level of
bearing clearance. If you notice that the clearance is
important, any damage or fissure replace it.
When you disassemble the bar, take the opportunity to
remove the remains of wood and sawdust in the area
of the lubrication hole (1) and the guide (2).
8.2.7. DROP PINION
The drive pinion is subject to high wear. Check the
drive pinion and if it detects signs of deep wear or
loss of material in any tooth, send your machine to the
technical service for replacement.
