Dust cup (Fig. 10)
Use the dust cup to prevent dust from falling over the tool
and on yourself when performing overhead drilling opera-
tions. Attach the dust cup to the bit as shown in Fig. 10.
The size of bits which the dust cup can be attached to is
as follows.
Drilling in wood or metal (Fig. 11 and 12)
Use the optional drill chuck assembly (standard equip-
ment for Model HR2440X). When installing it, refer to
“Installing or removing drill bit” described on the previous
page.
Hold the ring and turn the sleeve counterclockwise to
open the chuck jaws. Place the bit in the chuck as far as
it will go. Hold the ring firmly and turn the sleeve clock-
wise to tighten the chuck.
To remove the bit, hold the ring and turn the sleeve coun-
terclockwise. Set the action mode changing knob to
“rotation only”. You can drill up to 13 mm diameter in
metal and up to 32 mm diameter in wood.
CAUTION:
• Never use “rotation with hammering” when the drill
chuck assembly is installed on the tool. The drill chuck
assembly may be damaged.
Also, the drill chuck will come off when reversing the
tool. (For Model HR2440, HR2440X, HR2440F)
• 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 perfor-
mance and shorten the service life of the tool.
• There is a tremendous twisting force exerted on the
tool/bit at the time of hole breakthrough. 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.
• When performing diamond core drilling operation,
always set the change lever to the M position to use
“ rotation only ” action. If performing diamond core
drilling operation with “ rotation with hammering ”
action, the diamond core bit may be damaged.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
To maintain product safety and reliability, repairs, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Center.
