Rotation with hammering
Fig.8
For drilling in concrete, masonry, etc., rotate the action
mode changing knob to the
symbol. Use a tungsten-
carbide tipped bit.
Rotation only
Fig.9
For drilling in wood, metal or plastic materials, rotate the
action mode changing knob to the
symbol. Use a
twist drill bit or wood bit.
Hammering only
Fig.10
For chipping, scaling or demolition operations, rotate the
action mode changing knob to the
symbol. Use a
bull point, cold chisel, scaling chisel, etc.
Torque limiter
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.
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.
Hook
For Model HR2641
CAUTION:
•
Never hook the tool at high location or on
potentially unstable surface.
Fig.11
The hook is convenient for hanging the tool temporarily.
To use the hook, simply lift up hook until it snaps into
the open position.
When not in use, always lower hook until it snaps into
the closed position.
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.12
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
ﾟ
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
Fig.13
Clean the bit shank and apply bit grease before
installing the bit.
Fig.14
Insert the bit into the tool. Turn the bit and push it in until
it engages.
After installing, always make sure that the bit is securely
held in place by trying to pull it out.
Fig.15
To remove the bit, pull the chuck cover down all the way
and pull the bit out.
Bit angle
(when chipping, scaling or demolishing)
Fig.16
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.17
Rotate the action mode changing knob to the symbol.
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
uniform depth.
Fig.18
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.19
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 the figure.
Fig.20
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.21
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.
