tighten all three chuck holes evenly.
To remove the bit, turn the chuck key counterclockwise in
just one hole, then loosen the chuck by hand.

OPERATION

Holding tool
Fig.6
Fig.7
CAUTION:
This is a powerful tool. High torque is developed
•
and it is important that the tool should be securely
held and properly braced.
Grasp the switch handle with one hand and the spade
grip with the other hand. When drilling a large hole with a
hole saw, etc., the side grip (auxiliary handle) should be
used as a brace to maintain safe control of the tool.
When drilling action is forward (clockwise), the tool
should be braced to prevent a counterclockwise reaction
if the bit should bind. When reversing, brace the tool to
prevent a clockwise reaction. If the bit must be removed
from a partially drilled hole, be sure the tool is properly
braced before reversing.
Drilling operation
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 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.
Avoid drilling in material that you suspect contains
•
hidden nails or other things that may cause the bit
to bind or break.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and
•
unplugged before attempting to perform inspection
or maintenance.
Never use gasoline, benzine, thinner, alcohol or the
•
like. Discoloration, deformation or cracks may
result.
Replacing carbon brushes
Fig.8
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 identical 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.
Fig.9
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.
