Warning!
In case of repair, use only original parts supplied by the
manufacturer.
Use of non original parts may result in serious damage of the
engine.
7. Checking the spark plugs
For the normal operation of the spark plugs, ensure the
necessary free distance between the electrodes and in
addition clean the spark plug from residue of combustion.
The free distance between the electrodes is 0.7-0.8 mm.
Order of checking:
Note:
The oil change must be done more frequently if the
engine is subject to greater load or higher temperature.
Note:
The used oil must be recycled. It is recommended to
drain the oil in a can and send it to a processing plant for
regenerating.
DO NOT
DISPOSE THE CAN CONTAINING USED OIL AND
DO NOT POUR THE OIL ON THE EARTH.
1.
Remove the cap of the high voltage cable from the spark plug
and screw out the spark plug by means of a spark plug key.
2. Inspect the spark plug visually.
3.
Clean the spark plug with a brush, if you wish to use it in the
future.
4.
Measure the free distance between the electrodes by means of
a special sound (it should be purchased separately). Adjust the
free distance if necessary, by gently bending the side electrode.
5.
Check the skirt and threaded part of the plug.
6.
Change the spark plug if it seems to be worn out or there is any
crack on the insulator.
7.
Replace the plug by hand force, then tighten it with plug key.
