NOTE:
• After the clamper is secured, the maximum travel of the
drill holder is 47 mm by pulling the grip upward.
(Fig. 16)
Positioning the drilling hole (Fig. 17)
Mark a sign lightly as a position of drilling a hole into the
workpiece by placing the drill bit tip on the surface of
workpiece so that it is located between the drill bit and the
shoe.
CAUTION:
• At this time, place the workpiece so that the shoe con-
tacts as great part of surface of the workpiece as possi-
ble.
Drilling operation
This tool is intended for drilling in metal.
Apply machine oil when drilling.
After determining the position of a hole, turn on the tool
and start drilling by pulling the grip upward.
CAUTION:
• Press the grip lightly and softly so that the number of
drill bit rotation is not lessened.
• Hold the tool firmly so that the drill bit is perpendicular
to the workpiece.
• There is a tremendous twisting force exerted on the
tool/bit at the time of hole breakthrough. Reduce your
force applied on the grip by pulling it more lightly and
exert care when the bit begins to break through the
workpiece.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged 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
identical carbon brushes. (Fig. 18)
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. 19)
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized Service Centers, always
using Makita replacement parts.
