Drilling operation
First, turn the adjusting ring so that the pointer points to
the
marking. Then proceed as follows.
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.
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.
•
Never use gasoline, benzine, thinner, alcohol or
the like. Discoloration, deformation or cracks may
result.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers,
always using Makita replacement parts.
