FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Switch action (Fig. 1)
CAUTION:
• Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to the
"OFF" position when released.
To start the tool, simply pull the switch trigger. Tool speed
is increased by increasing pressure on the switch trigger.
Release the switch trigger to stop. For continuous opera-
tion, pull the switch trigger and then push in the lock but-
ton. To stop the tool from the locked position, pull the
switch trigger fully, then release it.
Lighting up the lamps (Fig. 2)
For Model HR2460F
CAUTION:
• Do not look in the light or see the source of light
directly.
To turn on the lamp, pull the trigger. Release the trigger
to turn it off.
NOTE:
• Use a dry cloth to wipe the dirt off the lens of lamp. Be
careful not to scratch the lens of lamp, or it may lower
the illumination.
Reversing switch action (Fig. 3)
CAUTION:
• Always check the direction of rotation before operation.
• Use the reversing switch only after the tool comes to a
complete stop. Changing the direction of rotation
before the tool stops may damage the tool.
• If the switch trigger can not be depressed, check to see
that the reversing switch is fully set to position
side) or (B side).
This tool has a reversing switch to change the direction of
rotation. Move the reversing switch lever to the
tion (A side) for clockwise rotation or to the
(B side) for counterclockwise rotation.
Selecting action mode (Fig. 4)
This tool employs an action mode changing knob. Select
one of the two modes suitable for your work needs by
using this knob.
For rotation only, turn the knob so that the arrow on the
knob points toward the
For rotation with hammering, turn the knob so that the
arrow on the knob points toward the
tool body.
CAUTION:
• Always set the knob fully to your desired mode symbol.
If you operate the tool with the knob positioned half-
way between the mode symbols, the tool may be dam-
aged.
• Use the knob after the tool comes to a complete stop.

Torque limiter
The torque limiter will actuate when a certain torque level
is reached. The motor will disengage from the output
shaft. When this happens, the bit will stop turning.
CAUTION:
• As soon as the torque limiter actuates, switch off the
tool immediately. This will help prevent premature wear
of the tool.
• Bits such as hole saw, which tend to pintch or catch
easily in the hole, are not appropriate for this tool. This
is because they will cause the torque limiter to actuate
too frequently.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Side grip (auxiliary handle) (Fig. 5)
CAUTION:
• Always use the side grip to ensure operating safety.
Install the side grip so that the teeth on the grip fit in
between the protrusions on the tool barrel. Then tighten
the grip by turning clockwise at the desired position. It
may be swung 360° so as to be secured at any position.
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. 6)
Insert the bit into the tool. Turn the bit and push it in until
it engages. (Fig. 7)
After installing, always make sure that the bit is securely
held in place by trying to pull it out.
(A
To remove the bit, pull the chuck cover down all the way
and pull the bit out. (Fig. 8)
posi-
Depth gauge (Fig. 9)
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. 10)
Use the dust cup to prevent dust from falling over the tool
and on yourself when performing overhead drilling opera-
tions. Attach the dust cup to the bit as shown in Fig. 10.
The size of bits which the dust cup can be attached to is
as follows.
