(2) Remove the air cleaner cover.

(5) Wipe off any oil that has come in to contact with the breather with a rag
or cloth.
(6) Install the element in the cleaner case.
(7) Attach the air cleaner cover and tighten the knob bolt.
• Clean the element several times a day, if excessive dust adheres to it.
• If operation continues with the element remaining not cleared of oil, oil in the air cleaner may fall outside, resulting in oil contamination.
3. Checking the spark plug
• When removing the spark plug, clean the spark plug and cylinder head first,
so that no dirt, sand, etc will enter the cylinder.
• You must remove the spark plug after the engine has cooled down in order to
avoid damaging the threaded hole in the cylinder.
• The spark plug must be installed properly into the threaded hole. If installed at
an angle, the threaded hole in the cylinder will get damaged.
(1) Opening/closing the plug cover
To open the plug cover, pull up on the seam of the plug cover projection
and slide in the direction of the "OPEN" indication as shown in the figure
at right.
When closing the cover, slide the cover in the "CLOSE" direction till the
click under the plug cover projection rides over the engine cover. Finally,
push in the projection.
(2) Removing the spark plug
Use an attached box wrench to remove or install the spark plug.
(3) Checking the spark plug
The clearance between two electrodes of spark plug (see the figure left)
is 0.7 to 0.8 mm. Adjust to the correct clearance when it is too wide or
too narrow.
Clean thoroughly or replace the spark plug if it has accumulated carbon
or contaminated.
(4) Replacing the spark plug
For replacement, use NGK-CMR6A.
