Makita HR2430 Power Hammer User Manual

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.
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
performance 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
unplugged before attempting to perform inspection or
maintenance.
To maintain product SAFETY and RELIABILITY, repairs, carbon
brush inspection and replacement, any other maintenance or
adjustment should be performed by Makita Authorized or Fac-
tory Service Centers, always using Makita replacement parts.
