OPERATION
Hammer drilling operation
When drilling in concrete, granite, tile, etc., move the
action mode change lever to the position of
use "rotation with hammering" action. Be sure to use a
tungsten-carbide tipped bit. Do not apply more pressure
when the hole becomes clogged with chips or particles.
Instead, run the tool at an idle, then remove the bit partially from the hole. By repeating this several times, the
hole will be cleaned out. After drilling the hole, use the
blow-out bulb to clean the dust out of the hole. (Fig. 9)
Drilling operation
When drilling in wood, metal or plastic materials, move
the action mode change lever to the position of
to use "rotation only" action.
Drilling in wood
When drilling in wood, the best results are obtained with
wood drills equipped with a guide screw. The guide
screw makes drilling easier by pulling the bit into the
workpiece.
Drilling in metal
To prevent the bit from slipping when starting a hole,
make an indentation with a center-punch and hammer at
the point to be drilled. Place the point of the bit in the
indentation and start drilling. Use a cutting lubricant
when drilling metals. The exceptions are iron and brass
which should be drilled dry.
CAUTION:
• Pressing excessively on the tool will not speed up the
drilling. In fact, this excessive pressure will only serve
to damage the tip of your bit, decrease the tool performance and shorten the service life of the tool.
• There is a tremendous force exerted on the tool/bit at
the time of hole break through. Hold the tool firmly and
exert care when the bit begins to break through the
workpiece.
• A stuck bit can be removed simply by setting the
reversing switch to reverse rotation in order to back out.
However, the tool may back out abruptly if you do not
hold it firmly.
• Always secure small workpieces in a vise or similar
hold-down device.
