Drill Operation; Modes Of Operation; Drilling (Non-Percussion); Hammer Drilling (Percussion) - Stanley HD08 User Manual

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 2
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
above. Then install the appropriate bit into the Geared
Chuck and tighten with the chuck key. Figure 2 illus-
trates the adapter, Geared Chuck, and various stan-
dard bits.

DRILL OPERATION

Operate the HD08 Hammer Drill as follows:
1. Observe all safety precautions.
2. Install the appropriate adapters and/or bits into the ham-
mer drill. Refer to the BIT INSTALLATION for details.
3. Set the hammer drill controls, side handle, and depth
gauge. Refer to the CONTROLS section for details.
IMPORTANT
When operating the hammer drill in hammer mode,
always use drill bits and accessories designed for
impact type applications. DO NOT USE STANDARD
DRILL BITS OR ACCESSORIES. THESE CAN
CRACK OR FRACTURE DURING OPERATION.
4. Move the hydraulic circuit control valve to the "ON" posi-
tion.
5. Squeeze the trigger to activate the drill.
6. Release the trigger to stop the drill.

MODES OF OPERATION

The hammer drill can operate in either drill only mode (with-
out percussion) or hammer drill mode (with percussion).
In drill only mode, the hammer drill can be used for periodic
OPERATION
light duty drilling. For extended use or heavy duty drilling
use the Stanley DLO7 Hydraulic Drill.
The following sections provide operational guide lines for
drilling, hammer drilling or chiseiling.

DRILLING (NON-PERCUSSION)

Use the Drill Chuck/Screwdriver Bit Adapter and the
Geared Chuck for periodic, light-duty drilling applications.
as described
With the Geared Chuck mounted on the tool, loosen the
chuck fi rst with the chuck key, and then turn the chuck
sleeve counterclockwise (looking at the chuck end of the
tool) by hand. Loosen until the bit shank fi ts into the hole for
the shank. Insert the appropriate bit shank into the chuck
and tighten the chuck sleeve clockwise by hand. Tighten
further by applying the chuck key successively to all three
guide holes of the chuck.
The chuck key must not be attached to the tool with a
chain, cord, or similar means.
When drilling into small work pieces, secure the piece
(by clamping in a vise or otherwise securing it to the work
surface) so that the piece is not turned by the drill bit during
drilling.

HAMMER DRILLING (PERCUSSION)

Press the hammer drill bit against the work surface before
squeezing the trigger. Do not operate the drill before con-
tacting the work surface.
When hammer drilling, do not exert heavy pressure on the
tool. Applying heavy pressure does not increase the drilling
speed. You need only press lightly. When the drill is with-
drawn from the work surface, the percussion action of the
hammer drill stops.

CHISELLING

Use the Bull-point Chisel Bit for light-duty chiselling work.
Press the hammer drill chisel bit against the work surface

IMPORTANT
When drilling into a structure that might contain elec-
trical wiring, be sure to know the location of the wiring
and avoid drilling into it. The housing can carry electri-
cal current from live electrical wires into which the drill
is accidently drilled resulting in injury or death.
