14.2.2 Replacement of oil in the engine and check of the oil
level
Oil is replaced only on the hot engine and according to the engi-
ne operation manual.
* Place the electric plant on a suitable raised basis and slight-
ly incline aside the sink hole.
* Unscrew the cap of the filler neck.
* Turn out the plug of the sink hole and pour oil out.
* After the removal of old oil, turn in the plug of the sink hole
and place the electric plant on the flat basis.
* Fill engine oil up to the top label of an oil dip stick.
* Tightly screw the cap of the oil-filler neck by hand.
Spilled engine oil should be immediately picked up.
Waste oil is subject to recycling according to rules currently in force.
Check of the oil level
* After opening the cap of the filler neck, insert the dip stick into the neck, but not screw (oil level should be
between the bottom and top labels). If necessary, add oil.
14.2.3 Check and replacement of the spark plug
If the electric plant worked before this procedure, its silencer is strongly heated. Danger of burn.
*
Remove the ignition wire from the spark plug.
* Unscrew the spark plug by a spark-plug wrench.
* If necessary, clean electrodes by a brass brush. If the spark plug is damaged, replace it.
* Check the interelectrode gap, if necessary install the appropriate gap. A feeler should be introduced smoothly between electrodes.
* In order to provide entry on the thread, screw the spark plug by hand and then draw it up by the spark-plug wrench through a half-turn.
* The spark plug should be tightly screwed. The insufficiently screwed spark plug is strongly heated and can cause the damage of the engine.
* Put the ignition wire on the spark plug.
* Spark plugs BPR6ES (NGK), and W20EPR-U (Denso) are recommended.
14.2.4 Cleaning and replacement of the air filter
* Carefully take out a cartridge.
* Wash out a foam-rubber replaceable element in warm water with a household was-
hing-up liquid, then carefully rinse and dry. Immerse the element in clean engine oil,
and then wring it out. If excessive oil remains on the insert, the engine will smoke at
the first start.
* Clean the pressboard cartridge by knocking out on a flat surface.
* When pollution is heavy, replace the filtering element.
