Maintenance - Makita HR2432 Betriebsanleitung

CAUTION:
• There is a tremendous and sudden twisting force
exerted on the tool/bit at the time of hole break-
through, when the hole becomes clogged with chips
and particles, or when striking reinforcing rods embed-
ded in the concrete. Always use the side grip (auxiliary
handle) and firmly hold the tool by both side grip and
switch handle during operations. Failure to do so may
result in the loss of control of the tool and potentially
severe injury.
NOTE:
Eccentricity in the bit rotation may occur while operating
the tool with no load. The tool automatically centers itself
during operation. This does not affect the drilling preci-
sion.
Blow-out bulb (optional accessory) (Fig. 24)
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.

Hold the tool firmly with both hands. Turn the tool on and

You can drill up to 13 mm diameter in metal and up to
32 mm diameter in wood.
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 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.
Diamond core drilling
When performing diamond core drilling operations,
always set the change lever to the
"rotation only" action.
CAUTION:
• If performing diamond core drilling operations using
"rotation with hammering" action, the diamond core bit
may be damaged.
