Torque Limiter - Makita HR2300 Betriebsanleitung

Hammering only (Fig. 9)
For chipping, scaling or demolition operations, rotate the
action mode changing knob to the
point, cold chisel, scaling chisel, etc.
CAUTION:
• Do not rotate the action mode changing knob when the
tool is running under load. The tool will be damaged.
• To avoid rapid wear on the mode change mechanism,
be sure that the action mode changing knob is always
positively located in one of the three action mode posi-
tions.
• Do not force the action mode change knob or do not
g
move it from symbol mode to
vise versa) at once. It may damage the tool. When turn-
g
ing the knob from
(or vise versa), stop it at
rotate the chuck clockwise (looking from the chuck
side) half turn or until it clicks. Then turn the knob to the
desired mode. If it is still difficult to turn the knob, rotate
the chuck again.

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 pinch 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. 10)
CAUTION:
• Always use the side grip to ensure operating safety.
Install the side grip so that the protrusions on the grip fit
in between the grooves 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. 11)
Insert the bit into the tool. Turn the bit and push it in until
it engages. (Fig. 12)
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. 13)

The bit can be secured at the desired angle. To change
the bit angle, rotate the action mode changing knob to
the O symbol. Turn the bit to the desired angle. (Fig. 14)

Then make sure that the bit is securely held in place by
turning it slightly.
Depth gauge
The depth gauge is convenient for drilling holes of uni-
form depth. (Fig. 16)
Press the lock button on the grip base in the direction of
arrow shown in the figure and with the lock button being
pressed insert the depth gauge into the hex. hole in the
grip base. (Fig. 17)
At this time, the depth gauge needs to be inserted so that
its toothed side is directed to the toothed side of hex hole
marking on the grip base as shown in Fig. 18.
Adjust the depth gauge to the desired depth by moving it
back and forth while pressing the lock button. After the
adjustment, release the lock button to lock the depth
gauge. (Fig. 19)
NOTE:
• Inserting the depth gauge with its toothed side not
directed to the toothed side of hex hole marking on the
grip base as shown in the figure does not allow the
depth gauge to be locked.
Dust cup (Fig. 20)
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. 20. The size of bits which the dust cup can be
attached to is as follows.
Dust cup 5
Dust cup 9
006406
There is another type of dust cup (accessory) which
helps you prevent dust from falling over the tool and on
yourself when performing overhead drilling operations.
Installing or removing the dust cup
Before installing the dust cup, remove the bit from the
tool if installed on the tool. Install the dust cup (acces-
sory) on the tool so that the
aligned with the grooves in the tool. (Fig. 21)
To remove the dust cup, pull the chuck cover in the direc-
tion as shown in Fig. 22 and with the chuck cover pulled
take the bit out of the tool.
And then grab the attachment at the foot of dust cup and
take it out. (Fig. 23)
NOTE:
• When installing or removing the dust cup, the cap may
come off the dust cup. At that time, proceed as follows.
Remove the bellows from the attachment and fit the
cap from the side shown in the figure with its carved
side facing upward so that the groove in the cap fits in
the inside periphery of the attachment. Finally, mount
the bellows that has been removed. (Fig. 24, 25 & 26)
