3.4.1 MAINTENANCE INTERVALS
This table lists the standard intervals for
service and maintenance of the machine
under normal operation conditions. In the
case of operation under harder conditions, e.g.
dusty surroundings, long hours of continuous
operation, etc., service intervals are shorter.

3.4.2 AIR FILTER
Regularly check the condition of the air lter for
contamination that could block it, thus reducing engine
performance and its service life.
To get to the air lter, remove the plastic casing on the side
of the machine by squeezing the two tabs from the top of
the casing (see pictures below). If the lter is dirty, remove it
and wash it in warm water with a detergent (e.g. grey soap).
Before reassembly, wipe it and dry it well. If the lter is
damaged, replace it with a new one.
3.4.4 SPARK PLUG
To ensure proper engine operation, the spark plug gap must
be properly set (0.5-0.7 mm).
To get to the spark plug, rst remove the machine housing
by unscrewing the hexagonal socket screw located on top
of the housing, and then pull the housing slightly upwards.
Then, locate the ignition cable with a rubber L-shaped cap
on one of its ends - after removing it, you will see the spark
plug. In the case of a used spark plug, i.e. removed from the
machine, before checking and possible adjustment of the
gap, rst clean the dirt accumulated on the tip of the spark
plug with a wire brush. You can also use extraction petrol.
3.4.3 FUEL FILTER
If the fuel lter is blocked, the engine speed and impact
energy of the machine will be reduced. To clean the lter,
unscrew the cap from the tank, pull out the lter through
the hole using a metal hook and clean the lter. If you need
to clean the fuel lter you should also clean the fuel tank.
