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.
When drilling in wood, metal or plastic materials, slide the
action mode change lever to the position of symbol to
use “rotation only” action.
Drilling in wood
When drilling in wood, the 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 center-punch 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 exceptions are iron and brass which
should be drilled dry.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
To maintain product safety and reliability, repairs,
maintenance or adjustment should be carried out by an
Makita Authorized Service Center.
