HAMMER DRILL OR DRILL ONLY
Most HD08 operations will be to drill holes in brittle ma-
terials such as rock, concrete, or other aggregate. This
mode of operation is selected at the knob below the tool
nose by aiming the picture of the hammer toward the
SDS chuck. For light drilling, the hammering action is
turned off by turning the knob so the picture of a drill bit
aims at the chuck. In both cases the tool must not be op-
erated without the knob pointing straight front-to-back.
There is no setting for hammering only, how ever, Figure
3 shows a bull-point chisel bit that can be inserted to
chip while the chuck is turning in the hammer drill mode.
IMPORTANT
Do not operate the tool unless the hammer/drill knob
Is set to one of the positions described above.
OPEN-CENTER CLOSED-CENTER OC/
CC
The OC/CC selectable model has a knurled knob on the
spool end holding the trigger strut and has two opposing
set screws showing the circuit setting. If the set screws
are horizontal (cross-wise), the setting is for closed-cen-
ter circuits. If the set screws are on a vertical line, the
setting is for open-center circuits. The knob can be twist-
ed to change and should be checked to avoid a wrong
setting. A decal on the trigger strut helps remind you of
the knob positions to select.
Note:
Single circuit type tools now have a knob on the
spool but it cannot be rotated.
DEPTH GAUGE
Drilling depth can be set using the depth gauge shown in
Figure 3. To set the gauge, loosen the side handle, slide
the gauge to the desired position, and tighten the locking
knob. Be sure the side handle is tight before operating
the tool.
The spacing between lines on the gauge is approxi-
mately 10 mm. The depth gauge can be removed when
not in use.
SIDE HANDLE
The side handle assembly, including the depth gauge,
fits over the front housing of the hammer drill to assist
the operator in maneuvering the tool.
To adjust the side handle to a comfortable position, twist
the hand grip in a counterclockwise direction and reposi-
tion the handle assembly. Once in position, tighten the
handle assembly by twisting the hand grip in a clockwise
direction.
Do not clamp the side handle to the black chuck collar.
Clamp the handle only to the housing, against the body
shoulder. The side handle should be securely attached
to the hammer drill during op eration.
BIT INSTALLATION
Bits with SDS Plus shanks are mounted directly into
the tool holder of the hammer drill. It is a good practice
to slightly grease or oil the bit shanks before inserting
them.
To install SDS Plus shanked bits or the bull-point chisel
bit, insert the shank into the tool holder at the nose of
the hammer drill. Then slightly turn the bit until it can be
pushed into the socket. To remove the bit, turn the tool
holder sleeve clockwise (while looking from the handle
of the drill to the bit holder) until it stops. Then pull the
bit out of the tool.

To install twin-groove shank, ratio thread shank, taper
shank, or through-hole shank bits, install the Drill Holder
Adapter as described above. Then simply screw the ap-
propriate bit holder onto the drill holder adapter. Figure
3 illustrates these adapters and bit holders.
To install the Geared Chuck for use with standard drill
bits and screwdriver bits in non-percussion drill mode,
install the Drill Chuck/Screwdriver Bit Adapter as de-
scribed above. Then install the appropriate bit into the
