*1 Dust removal
When an excessive amount of dust is deposited in the
dust bag, dust-collecting effi ciency will sharply drop.
Remove dust from the bag when it is deposited up to
about 2/3 the bag capacity, where by dust collecting
effi ciency (as well as working effi ciency) will be ensured.
Remove dust from the bag as follows:
(1) Loosen the support bar and remove the dust bag.
(Fig. 4)
(2) The bag inlet can be opened by unzipping the slide
fastener.
How to select proper sanding belt

your specifi c purpose, by referring to Table 1 and 2 below.

CAUTION
○ For grain sizes, refer to Table 1
○ Sanding belt grain should be coarser than sandpaper
used for manual work.
○ Use sanding belt of same grain size until uniform
surface is obtained. Changing grain sizes may result in
poor fi nish.

MAINTENANCE AND INSPECTION

1. Inspecting the sanding belt
Since continued use of a worn-out sanding belt will
degrade effi ciency, replace the sanding belt as soon as
excessive abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws be
loose, retighten them immediately. Failure to do so could
result in serious hazard.
