OPERATION

CAUTION:

Always use the side grip (auxiliary 

handle) and firmly hold the tool by both side grip 

and switch handle during operations.

CAUTION:

Always make sure that the work-

piece is secured before operation.

Hammer drilling operation

CAUTION:

 There is tremendous and sudden 

twisting force exerted on the tool/drill 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 opera-

tions.

 Failure to do so may result in the loss of control 

of the tool and potentially severe injury.

Set the action mode changing knob to the 

 symbol. 

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.

NOTE:

 Eccentricity in the drill bit rotation may occur 

while operating the tool with no load. The tool auto-

matically centers itself during operation. This does not 

affect the drilling precision.

Chipping/Scaling/Demolition

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

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.

NOTICE:

Never use “rotation with hammering” 

when the drill chuck is installed on the tool.

 The 

drill chuck may be damaged. 

Also, the drill chuck will come off when reversing the 

tool.

NOTICE:

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.

Set the action mode changing knob to the   symbol. 

You can drill up to 13 mm (1/2″) diameter in metal and 

up to 32 mm (1-1/4″) diameter in wood.

Use a drill chuck assembly (optional accessory). When 

installing it, refer to the section “Installing or removing 

drill bit/chisel”.

 Drill chuck assembly (optional accessory)

To install the drill bit, place it in the chuck as far as it will 

go. Tighten the chuck by hand. Place the chuck key in 

each of the three holes and tighten clockwise. Be sure 

to tighten all three chuck holes evenly. 

To remove the drill bit, turn the chuck key counterclock-

wise in just one hole, then loosen the chuck by hand.

Diamond core drilling

NOTICE:

If performing diamond core drilling 

operations using “rotation with hammering” 

action, the diamond core bit may be damaged.

When performing diamond core drilling operations, 
always set the change lever to the   position to use 

"rotation only" action.

MAINTENANCE

CAUTION:

Always be sure that the tool is 

switched off and unplugged 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.
