Reversing switch action (Fig. 4)
For 6410
CAUTION:
• Always check the direction of rotation before drilling.
• Use the reversing switch lever only after the tool comes
to a complete stop. Changing the direction of rotation
before the tool stops may damage the tool.
This tool has a reversing switch to change the direction of
rotation. Move the reversing switch lever to
the
d position for clockwise rotation or the e position
for counterclockwise rotation.
Drilling operation
• Drilling in wood
When drilling in wood, best results are obtained with
wood drills equipped with a guide screw. The guide
screw makes drilling easier by pulling the bit into the
workpiece.
• Drilling in metal
To prevent the bit from slipping when starting a hole,
make an indentation with a centerpunch and hammer
at the point to be drilled. Place the point of the bit in the
indentation and start drilling.
Use a cutting lubricant when drilling metals. The excep-
tions are iron and brass which should be drilled dry.
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 perfor-
mance and shorten the service life of the tool.
• There is a tremendous 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. (For 6410 only)
• Always secure small workpieces in a vise or similar
hold-down device.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
To maintain product safety and reliability, repairs, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Center.
