establishment or individual.

maintenance.
• Do not modify the machine nor disassemble
the engine.

■ AIR CLEANER
The air cleaner is adhered with much dusts
produced by a cutting operation. At the end of day’s
operation, be sure to check and clean it as follows:
1. Remove 2 screws above the air cleaner cover
and remove the cover.
2. Remove 2 screws above a top plate and remove
the plate.
3. Remove a main filter together with a felt filter.
4. Remove the felt filter from the main filter.
5. Remove adhered dusts on the main filter by
tapping the edge of the filter on a hard plane, for
example.
• The main and felt filters are of dry type. Do not
wet with water nor apply oils. Those will degrade
the performance.
• Do not apply high pressure air blows or a wire
brush to clean the main filter. These will quicken
clogging or damaging of the filter.
6. Dusts adhered on the felt filter are removed by
gently needing it. For heavy contamination, wash
in warm detergent water and dry thoroughly.
Then reassemble to the main filter as original.
