Bit grease
Coat the bit shank head beforehand with a small amount
of bit grease (about 0.5 – 1 g).
This chuck lubrication assures smooth action and longer
service life.
Installing or removing the bit
Clean the bit shank and apply bit grease before installing
the bit. (Fig. 10)
Insert the bit into the tool. Turn the bit and push it in until
it engages. (Fig. 11)
After installing, always make sure that the bit is securely
held in place by trying to pull it out.
To remove the bit, pull the chuck cover down all the way
and pull the bit out. (Fig. 12)
Bit angle (when chipping, scaling or demolishing)
The bit can be secured at the desired angle. To change
the bit angle, depress the lock button and rotate the
action mode changing knob to the O symbol. Turn the
bit to the desired angle. (Fig. 13)
Depress the lock button and rotate the action mode
changing knob to the
the bit is securely held in place by turning it slightly.
(Fig. 14)
Depth gauge (Fig. 15)
The depth gauge is convenient for drilling holes of uni-
form depth. Loosen the side grip and insert the depth
gauge into the hole in the side grip. Adjust the depth
gauge to the desired depth and tighten the side grip.
NOTE:
• The depth gauge cannot be used at the position where
the depth gauge strikes against the gear housing.
Dust cup (Fig. 16)
Use the dust cup to prevent dust from falling over the tool
and on yourself when performing overhead drilling
operations. Attach the dust cup to the bit as shown in
Fig. 16. The size of bits which the dust cup can be
attached to is as follows.
Dust cup 5
Dust cup 9

OPERATION

Hammer drilling operation (Fig. 17)
Set the action mode changing knob to the
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.

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. 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
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, 22 & 23)
For Model HR2470/HR2470F
Use the optional drill chuck assembly. When installing it,
refer to "Installing or removing the bit" described on the
previous page.
For Model HR2470T/HR2470FT
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.
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
clockwise to tighten the chuck. To remove the bit, hold
the ring and turn the sleeve counterclockwise.
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
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.
