operations. Attach the dust cup to the bit as shown in the 
figure. The size of bits which the dust cup can be attached 
to is as follows.

OPERATION

Hammer drilling operation (Fig. 17)

Set the action mode changing knob to the 

 symbol.

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.

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. 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.

NOTE:

Eccentricity in the bit rotation may occur while operating 
the tool with no load. The tool automatically centers itself 
during operation. This does not affect the drilling 
precision.

Blow-out bulb (optional accessory) 
(Fig. 18)

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

Chipping/Scaling/Demolition (Fig. 19)

Set the action mode changing knob to the   symbol.
Hold the tool firmly with both hands. Turn the tool on and 
apply slight pressure on the tool so that the tool will not 
bounce around, uncontrolled. Pressing very hard on the 
tool will not increase the efficiency.

Drilling in wood or metal (Fig. 20 & 21)

Use the optional drill chuck assembly. When installing it, 
refer to “Installing or removing the bit” described on the 
previous page.
Set the action mode changing knob so that the pointer 
points to the   symbol.

CAUTION:

• Never use “rotation with hammering” when the drill 

chuck assembly is installed on the tool. The drill chuck 
assembly may be damaged. Also, the drill chuck will 
come off when reversing the tool.

• 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 twisting force exerted on the 

tool/bit at the time of hole breakthrough. 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.

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.

Replacing carbon brushes (Fig. 22)

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.
Remove holder cap covers by inserting the slotted bit 
screwdriver into the recessed part in the tool and lifting it 
up. 

(Fig. 23)

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. 24)

Remount the holder cap covers on the tool.
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.
