Makita HR2800 Instruction Manual page 9

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 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.
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.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and
•
unplugged 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
replacement parts.
