NOTE:

• If you connect a vacuum cleaner to your hammer,

cleaner operations can be performed. Dust cap needs

to be removed from the dust cup before the connection.

(Fig. 27)

OPERATION

Always use the side grip (auxiliary handle) and firmly

hold the tool by both side grip and switch handle during

operations.

Hammer drilling operation (Fig. 28)

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 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.

Set the action mode changing knob to the symbol.

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

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 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. 29)

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

dust out of the hole.

Chipping/Scaling/Demolition

For Models HR2310T, HR2610, HR2610T, HR2611F,

HR2611FT

Set the action mode changing knob to the

g 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. (Fig. 30)

Drilling in wood or metal

For Models HR2300, HR2600, HR2601, HR2610,

HR2611F

Use the optional drill chuck assembly. When installing it,

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

previous page. (Fig. 31)

For Models HR2310T, HR2610T, HR2611FT

Use the quick change drill chuck as standard equipment.

When installing it, refer to “changing the quick change

chuck for SDS-plus” described on the previous page.

(Fig. 32 & 33)

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 counterclockwise. (Fig. 34)

Set the action mode changing knob to the

m symbol.

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 quick

change drill chuck is installed on the tool. The quick

change drill chuck 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.

Diamond core drilling

When performing diamond core drilling operations,

always set the change lever to the m position to use “rota-

tion only” action.

CAUTION:

• If performing diamond core drilling operations using

“rotation with hammering” action, the diamond core bit

may be damaged.

Operation when using the dust cup (accessory)

(Fig. 35)

Operate the tool with the dust cup against the ceiling sur-

face.

NOTE:

• The dust cup (accessory) is intended only for drilling in

the ceramic workpiece such as concrete and mortar.

Do not use the tool with the dust cup when drilling in

metal or similar. Using the dust cup for drilling in the

metal may damage the dust cup due to the heat pro-

duced by small metal dust or similar.

• Empty the dust cup before removing a drill bit.

• When using the dust cup, make sure that the dust cap

is mounted on it securely.
