For Model DHR243 (Fig. 23, 24 & 25)
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.
Use the quick change drill chuck as standard equipment.
When installing it, refer to the section “Changing the
quick change chuck for SDS-plus”.
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 counterclockwise.
Set the action mode changing knob to the m symbol.
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 quick
change drill chuck is installed on the tool. The quick
change drill chuck may be damaged.
Also, the drill chuck will come off when reversing the
tool.
• 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.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before attempting to perform
inspection or maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
To maintain product SAFETY and RELIABILITY, repairs,
carbon brush inspection and replacement, any other
maintenance or adjustment should be performed by
Makita Authorized Service Centers, always using Makita
