Spark Plug Maintenance; Fuel Filter - ATIKA GHB 760 A Manual Original

MAINTENANCE
1. Unscrew the machine knob nut from the air filter cover. Now
remove the cover.
2. Unscrew the wing nut from the air filter and remove the filter.
3. Remove the foam filter from the paper filter.
4. Inspect both air filter elements and replace them if
damaged. Paper elements must always be replaced at the
scheduled intervals.
5. Clean the filter elements if they shall be reused.
Paper air filter element: Tap the filter element several
times on a hard surface to remove the dust or blow it clean
with compressed air (not over 200 kPa). Never attempt to
brush off the dirt; brushing lets the dirt penetrate the fibres.
Foam air filter element: Clean in warm soap water, rinse
thoroughly and dry well. Submerge the filter element in
clean engine oil and squeeze out the excess oil. The engine
smokes if the foam contains too much excess oil.
6. Wipe off the dirt from the inside of the air filter bracket using
a wet rag. Make sure that no dirt enters the air line to the
carburettor.
7. Place the foam element on the paper element and install the
assembled air filter again. Check to make sure that the seal
is installed under the air filter. Tighten the wings nuts of the
air filter.
8. Install the air filter cover and tighten the machine knob nut of
the cover.
CLEANING THE FUEL FILTER

Wrong spark plugs may damage the engine.
1. Pull off the spark plug connector and clean the connector

3. Inspect the spark plug. Replace the spark plug if the
electrodes or the insulator are damaged.
4. Measure the electrode gap with an appropriate feeler
gauge.
The gap must be 0.70 – 0.80 mm. Correct the gap, if
necessary, by carefully bending the outer electrode slightly.
0.7 – 0.8 mm
5. Carefully screw in the spark plug by hand to prevent
stripping the thread.
6. Tighten the spark plug with the spark plug wrench after it is
seated.
If you are installing a used spark plug, tighten it by 1/8 –
1/4 turn.
If you are installing a new spark plug, tighten it by 1/2 – 1/4

A loose spark plug may overheat and damage the engine.
Tightening the spark plug too firmly may damage the thread
