First, turn the action mode changing ring so that the
arrow on the tool body points to the
the adjusting ring to the proper torque level for your
work. Then proceed as follows.
Place the point of the driver bit in the screw head and
apply pressure to the tool. Start the tool slowly and then
increase the speed gradually. Release the switch trigger
as soon as the clutch cuts in.
CAUTION:
• Make sure that the driver bit is inserted straight
in the screw head, or the screw and/or bit may
be damaged.
NOTE:
• When driving wood screws, predrill pilot holes
to make driving easier and to prevent splitting of
the workpiece. See the chart.

Drilling operation
First, turn the adjusting ring so that the pointer points to
the marking. Then proceed as follows.
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.
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 excep-
tions are iron and brass which should be drilled dry.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
the battery cartridge is removed before attempt-
ing 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 per-
formed by Makita Authorized Service Centers, always
using Makita replacement parts.
