• Remove only the outer air filter element (3).
• Clean the inside of the air filter housing (4).
• Blow out the inside and outside of the air filter
element (3) with compressed air (the air pres-
sure must be below 205 kPa) until the dust de-
posits are completely removed.
• Replace the air filter element.
• When reassembling, make sure that the air fil-
ter cover is fitted correctly (the TOP mark (ar-
row) must point upwards). Then fix it with the
screws (1).
• The inner element must not be removed.
NOTE: If the air intake is insufficient even after clean-
ing the air filter element or the colour of the exhaust
gases is abnormal, the air filter element must be re-
placed
NOTE: When operating the machine in extremely
dusty environments, the air filter element must be
checked and cleaned more frequently than the
specified maintenance intervals.
16.2.16 Check spark plug
• After the engine has cooled down, remove the
spark plug connector and clean it with com-
pressed air.
• Unscrew the spark plug (1) with a spark plug
wrench.
• Check the spark plug (1) for dirt and, if neces-
sary, clean it with a copper wire brush.
• Check electrode gap (0.7 – 0.8 mm).
•
The sealing washer should also still be in good
condition.
• If the electrodes are worn or the sealing washer
is damaged, replace the spark plug (1).
NOTE: Use only recommended spark plugs.
• Screw the spark plug (1) back in by hand the
first few turns.
• When the spark plug (1) is firmly seated,
tighten it a further 1/4 turn with the spark plug
wrench.
• Reattach spark plug connector and check for
tight fit.
NOTE: A loose spark plug can overheat and damage
the engine. Overtightening the spark plug, in turn,
can damage the thread in the cylinder head.
