ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before carrying out any
work on the tool.
Installing or removing driver bit or drill bit
(Fig. 7)
Turn the sleeve counterclockwise to open the chuck jaws.
Place the bit in the chuck as far as it will go. Turn the
sleeve clockwise to tighten the chuck.
To remove the bit, turn the sleeve counterclockwise.
OPERATION
CAUTION:
• Always insert the battery cartridge all the way until it
locks in place. If not, it may accidentally fall out of the
tool, causing injury to you or someone around you.
Hold the tool firmly with one hand on the grip and the
other hand on the bottom of the battery cartridge to
control the twisting action.
Screwdriving operation (Fig. 8)
CAUTION:
• Adjust the adjusting ring to the proper torque level for
your work.
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.

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.
Using the tool as a hand screwdriver
(Fig. 9)
Switch off the tool.
Move the lock button to the locked position A.
Turn the tool.
NOTE:
• This use is convenient for checking the screwdriving.
• Do not use the tool for work requiring excessive force,
such as tightening bolt or removing rusted screws.
Using holster
CAUTION:
• Do not use for tools such as a drill with a bit installed on
them.
• Turn off a tool and wait until it comes to a complete
stop before placing in the holster.
Be sure to close the holster securely so that it holds the
tool firmly.
Thread a waist belt or similar through holster holder.
Put the tool in the holster and lock it with the holster
button. (Fig. 10 & 11)
Two bits can be retained at the front of holster. (Fig. 12)
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before attempting to
perform inspection or maintenance.
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.
