Maintenance - Makita HR3200C Instruction Manual

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.
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
"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.
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.
