Drilling operation
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 drill bit into
the workpiece.
Drilling in metal
To prevent the drill 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 drill bit in the indentation and start drilling.
Use a cutting lubricant when drilling metals. The excep-
tions 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 drill bit, decrease
the tool performance and shorten the service life of the tool.
CAUTION:
Hold the tool firmly and exert care
when the drill bit begins to break through the
workpiece. There is a tremendous force exerted on
the tool/drill bit at the time of hole break through.
CAUTION:
A stuck drill 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.
CAUTION:
Always secure workpieces in a
vise or similar hold-down device.
CAUTION:
If the tool is operated continuously until
the battery cartridge has discharged, allow the tool to rest
for 15 minutes before proceeding with a fresh battery.

MAINTENANCE

CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed before
attempting to perform inspection or maintenance.

or the like. Discoloration, deformation or cracks may result.
