The quick change drill chuck may be damaged.
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.
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
position to use
"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.
Lubrication
CAUTION:
This servicing should be performed by Makita
Authorized or Factory Service Centers only.
This tool requires no hourly or daily lubrication because
it has a grease-packed lubrication system. Lubricate the
tool every time the carbon brushes are replaced.
Run the tool for several minutes to warm it up. Switch off
and unplug the tool.
