(1) Removing the bit
Securely hold the main unit and pull out the bit by
holding the tip with your thumb. (Fig. 13)
(2) Installing the Bit
Install the bit with steps opposite of when removing.
Insert the bit so that the right and left sides are
equal, as shown in Fig. 14.
3. Installing/Removing the side handle
CAUTION:
Firmly install the side handle. If loose, the side
handle may gyrate or fall out and cause bodily
injury.
(1) Install the side handle so that the protrusions on
the main unit and grooves on the side handle
interlock. Tighten the grip after checking that the
side handle is not riding on the slip prevention
protrusion. (Fig. 15)
(2) Loosen the grip to remove the side handle.
4. Mounting and dismounting the bit
(1) Mounting the bit
Loosen the sleeve by turning it toward the left (in the
counterclockwise direction as viewed from the front)
to open the clip on the keyless chuck. After inserting
a driver bit, etc., into the keyless drill chuck, and
tighten the sleeve by turning it toward the right (in
the clockwise direction as viewed from the front).
(See Fig. 16)
NOTE: If the sleeve becomes loose during operation,
tighten it further.
The tightening force becomes stronger when
the sleeve is tightened.
(2) Dismounting the bit
Loosen the sleeve by turning it toward the left (in the counterclockwise direction as
viewed from the front), and then take out the bit, etc. (See Fig. 17)
NOTE: If the sleeve is tightened in a state where the clip of the keyless chuck is opened to
a maximum limit, a click noise may occur. This is the noise that occurs when the
loosening of the keyless chuck is prevented and is not a malfunction.
CAUTION:
When mounting a bit into the keyless chuck, tighten firmly. If the sleeve is not tight,
the bit may slip or fall out, causing injury.
