OPERATION

CAUTION:

Always insert the battery cartridge 

all the way until it locks in place.

 If you can see the 

red indicator on the upper side of the button, it is not 

locked completely. Insert it fully until the red indicator 

cannot be seen. If not, it may accidentally fall out of 

the tool, causing injury to you or someone around 

you.

CAUTION:

When the speed comes down 

extremely, reduce the load or stop the tool to 

avoid the tool damage.

Always use the side grip (auxiliary handle) and firmly 

hold the tool by both side grip and switch handle during 

operations. Failure to do so may result in the loss of 

control of the tool and potentially severe injury.

Screwdriving operation

CAUTION:

Adjust the adjusting ring to the 

proper torque level for your work.

CAUTION:

Make sure that the driver bit is 

inserted straight in the screw head, or the screw 

and/or driver bit may be damaged.

First, turn the action mode changing ring so that the 

arrow on the tool body points to the 

 marking.

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.

NOTE:

 When driving wood screw, pre-drill a pilot hole 

2/3 the diameter of the screw. It makes driving easier 

and prevents splitting of the workpiece.

Hammer drilling operation

CAUTION:

There is a tremendous and sud-

den twisting force exerted on the tool/drill bit 

at the time of hole breakthrough, 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 drill bit.

Position the drill 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 drill 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

 Blow-out bulb

After drilling the hole, use the blow-out bulb to clean the 

dust out of the hole.

Drilling operation

First, turn the action mode changing ring so that the arrow 

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 drill bit into the workpiece.

Drilling in metal

To prevent the drill 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 

drill 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.

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 drill 

bit, decrease the tool performance and shorten the 

service life of the tool.

CAUTION:

Hold the tool firmly and exert care 

when the drill bit begins to break through the 

workpiece.

 There is a tremendous force exerted on 

the tool/drill bit at the time of hole break through.

CAUTION:

A stuck drill 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.

CAUTION:

Always secure workpieces in a 

vise or similar hold-down device.

CAUTION:

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.

NOTICE:

Never use gasoline, benzine, thinner, 

alcohol or the like. Discoloration, deformation or 

cracks may result.

To maintain product SAFETY and RELIABILITY, repairs, carbon 

brush inspection and replacement, any other maintenance or 

adjustment should be performed by Makita Authorized or Factory 

Service Centers, always using Makita replacement parts.
