Drilling in wood or metal
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.
NOTICE:
Never use “rotation with hammering”
when the drill chuck is installed on the tool.
The
drill chuck may be damaged.
Also, the drill chuck will come off when reversing the
tool.
NOTICE:
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.
Set the action mode changing knob to the symbol.
For HR2650/HR2651/HR2661
Optional accessory
Attach the chuck adapter to a keyless drill chuck to
which 1/2"-20 size screw can be installed, and then

Disposing of dust
CAUTION:
Always be sure that the tool is
switched off and unplugged before carrying out
any work on the tool.
CAUTION:
Be sure to wear dust mask when
disposing of dust.
CAUTION:
Empty the dust case regularly
before the dust case becomes full.
Failure to do so
may decrease the dust collection performance and
cause dust inhalation.
CAUTION:
The performance of dust collection
decreases if the filter in the dust case become
clogged. Replace the filter with new one after
approximately 200 times of dust fulfillment as a
guide.
Failure to do so may cause dust inhalation.
