Maintenance; Optional Accessories - Makita DHR164 Instruction Manual

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 the
•
battery cartridge is removed before attempting to
perform inspection or maintenance.
Never use gasoline, benzine, thinner, alcohol or
•
the like. Discoloration, deformation or cracks may
result.
