HOW TO USE
CAUTION:
䡬 If the tipped saw blade stops suddenly, makes an
abnormal sound, etc., immediately turn off the
switch.
䡬 Do not use cutting oil on the blade.
Such substances as cutting oil, polishing oils and
waxes can catch fire from sparks when cutting.
䡬 When using the metal cutting saw, always wear eye
protection.
䡬 Be sure that the materials are secured firmly in
position. If the materials are not properly secured
in position, they may fly about causing damage to
the tipped saw blade.
䡬 When cutting is finished, immediately turn off the
power and unplug the metal cutting saw.
䡬 Be careful as not to cut the unit cord with the
rotating tipped saw blade.
䡬 Discard cutting dust before the dust cover becomes
completely full.
If the metal cutting saw is used when the cutting
dust is pressed against the dust cover, the
performance of the dust collector will drop and the
temperature of the dust cover (B) will rise. This may
cause dust cover (C) to warp or melt.
䡬 Wear ear plugs to protect ears from effects of the
sound.
䡬 If the cutting depth adjustment is too shallow, the
cut may tend to open lowering the performance of
the cutting dust collector.
䡬 When cutting the surface of a wall, the rate of
accumulation of cutting dust inside the dust cover
may change and may lower the performance of the
cutting dust collector.
䡬 Use a tipped saw blade that is suitable for the
material being cut.
䡬 When cutting, push the blade straight and forward
without letting the blade curve to the left and right.
䡬 Push the blade forward slowly, especially when
beginning to cut and when coming to the end of
the cut.
䡬 Do not turn on the metal cutting saw with the blade
pressed against the cutting material. Do not turn
off the metal cutting saw in the midst of cutting
a piece of material. In a case where it is absolutely
