■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.
IMPORTANT
•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.
