OPERATION

Hammer drilling operation

Position the bit at the desired location for the hole, then

pull the switch trigger. Do not force the tool. Light pres-

sure gives best results. Keep the tool in position and pre-

vent 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 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 con-

crete. 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 operat-

ing 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. 11)

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

dust out of the hole.

Drilling in wood or metal (Fig. 12 & 13)

Use the optional drill chuck assembly. When installing it,

refer to “Installing or removing drill bit” described on the

previous page.

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 clock-

wise to tighten the chuck.

To remove the bit, hold the ring and turn the sleeve coun-

terclockwise. Set the action mode changing knob to

“rotation only”.

You can drill up to 13 mm diameter in metal and up to

32 mm diameter in wood.

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 perfor-

mance 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.

• When performing diamond core drilling operations,

always set the change lever to the position to use

“rotation only” action. If performing diamond core drill-

ing operations using “rotation with hammering” action,

the diamond core bit may be damaged.

MAINTENANCE

CAUTION:

• Always be sure that the tool is switched off and

unplugged before attempting to perform inspection or

maintenance.

To maintain product SAFETY and RELIABILITY, repairs,

carbon brush inspection and replacement, any other

maintenance or adjustment should be performed by Mak-

ita Authorized Service Centers, always using Makita

replacement parts.
