CAUTION:
• Before inserting the battery cartridge into the tool, always
check to see that the switch trigger actuates properly and
returns to the "OFF" position when released.
To start the tool, simply pull the switch trigger. Tool
speed is increased by increasing pressure on the switch
trigger. Release the switch trigger to stop.
Reversing switch action
Fig.3
This tool has a reversing switch to change the direction
of rotation. Depress the reversing switch lever from the A
side for clockwise rotation or from the B side for
counterclockwise rotation.
When the reversing switch lever is in the neutral position,
the switch trigger cannot be pulled.
CAUTION:
• Always check the direction of rotation before
operation.
• Use the reversing switch only after the tool comes
to a complete stop. Changing the direction of
rotation before the tool stops may damage the tool.
• When not operating the tool, always set the
reversing switch lever to the neutral position.
Speed change
Fig.4
To change the speed, first switch off the tool and then
slide the speed change lever to the "2" side for high
speed or "1" side for low speed. Be sure that the speed
change lever is set to the correct position before
operation. Use the right speed for your job.

CAUTION:
• Always set the speed change lever fully to the
correct position. If you operate the tool with the
speed change lever positioned halfway between
the "1" side and "2" side, the tool may be
damaged.
• Do not use the speed change lever while the tool is
running. The tool may be damaged.
Selecting the action mode
Fig.5
This tool employs an action mode changing ring. Select
one of the three modes suitable for your work needs by
using this ring.
For rotation only, turn the ring so that the arrow on the
tool body points toward the mark on the ring.
For rotation with hammering, turn the ring so that the
arrow points toward the mark on the ring.
For rotation with clutch, turn the ring so that the arrow
points toward the mark on the ring.
CAUTION:
• Always set the ring correctly to your desired mode
mark. If you operate the tool with the ring
positioned halfway between the mode marks, the
tool may be damaged.
Adjusting the fastening torque
Fig.6
The fastening torque can be adjusted in 16 steps by
turning the adjusting ring so that its graduations are
aligned with the arrow on the tool body. The fastening
torque is minimum when the number 1 is aligned with
the arrow, and maximum when the number 16 is aligned
with the arrow.
Before actual operation, drive a trial screw into your
material or a piece of duplicate material to determine
which torque level is required for a particular application.
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
Hold the ring and turn the sleeve counterclockwise to
open the chuck jaws. Place the bit in the chuck as far as
it will go. Hold the ring firmly and turn the sleeve
clockwise to tighten the chuck.
To remove the bit, hold the ring and turn the sleeve
counterclockwise.
OPERATION
Hammer drilling operation
CAUTION:
• There is a tremendous and sudden twisting force
exerted on the tool/bit at the time of hole
break-through, when the hole becomes clogged
with chips and particles, or when striking
reinforcing rods embedded in the concrete.
First, turn the action mode changing ring so that the arrow on
the tool body points to the marking. The adjusting ring
can be aligned in any torque levels for this operation.
Be sure to use a tungsten-carbide tipped bit.
Position the bit at the desired location for the hole, then
pull the switch trigger. Do not force the tool. Light
pressure gives best results. Keep the tool in position and
prevent it from slipping away from the hole.
Do not apply more pressure when the hole becomes
clogged with chips or particles. Instead, run the tool at
an idle, then remove the bit partially from the hole. By
repeating this several times, the hole will be cleaned out
and normal drilling may be resumed.
Blow-out bulb (optional accessory)
Fig.8
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.
Screwdriving operation
Fig.9
First, turn the action mode changing ring so that the
arrow on the tool body points to the marking. Adjust
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.
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.
