CAUTION:
• 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 force exerted on the tool/bit at the
time of hole break through. 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.
• If the tool is operated continuously until the battery
cartridge has discharged, allow the tool to rest for 15
minutes before proceeding with a fresh battery.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before attempting to
perform inspection or maintenance.
Replacing carbon brushes
Remove and check the carbon brushes regularly. Replace
when they wear down to the limit mark. Keep the carbon
brushes clean and free to slip in the holders. Both carbon
brushes should be replaced at the same time. Use only iden-
tical carbon brushes.
Use a screwdriver to remove the brush holder caps. Take out
the worn carbon brushes, insert the new ones and secure
the brush holder caps.
After replacing brushes, insert the battery cartridge into the
tool and break in brushes by running tool with no load for
about 1 minute. Then check the tool while running and elec-
tric brake operation when releasing the switch trigger. If elec-
tric brake is not working well, ask your local Makita service
center for repair.
