SELECTING A DRILLING MODE See Figure 14. To adjust for type of drilling, slide the mode selector on the side of the motor housing to hammer mode, screw mode, or drilling mode. Select screw mode for driving screws. Screw mode operates with user adjusted torque. (See Adjustable Torque Clutch.) Drill mode is for full torque operations only and bypasses the clutch setting. Select drill mode when drilling with twist drills, hole saws, etc., in soft materials, or when the application calls for full torque of the drill. Select hammer mode for masonry, brick, tile, and concrete. For maximum performance, use carbide-tipped impact masonry bits. To use the hammer mode: [] Rotate the mode selector to the hammer mode. [] Apply light pressure and medium speed for best results in brick. [] Apply additional pressure and high speed for hard materials such as concrete. [] When drilling holes in tile, practice on a scrap piece to determine the best speed and pressure. NOTE: The hammer drill has not been designed for reverse hammering.

SELECTING
A DRILLING
MODE
See Figure
14.
To adjust for type of drilling, slide the mode selector
on
the side of the motor housing to hammer mode, screw
mode, or drilling mode.
Select screw
mode for driving
screws.
Screw mode
operates
with user adjusted
torque.
(See Adjustable
Torque Clutch.)
Drill mode is for full torque operations
only and bypasses
the clutch setting.
Select drill mode when drilling with
twist drills, hole saws, etc., in soft materials,
or when the
application
calls for full torque of the drill.
Select hammer
mode for masonry, brick, tile, and
concrete.
For maximum
performance,
use carbide-tipped
impact
masonry
bits.
To use the hammer
mode:
[]
Rotate the mode selector to the hammer
mode.
[]
Apply light pressure and medium speed for best results
in brick.
[]
Apply additional
pressure and high speed for hard
materials
such as concrete.
[]
When drilling
holes in tile, practice
on a scrap piece to
determine
the best speed and pressure.
NOTE: The hammer drill has not been designed
for
reverse hammering.

WARNING:
Be prepared
for binding

breakthrough.
When these situations
occur, drill has
a tendency
to grab and kick opposite
to the direction
of rotation
and could cause loss of control when
breaking through
material.
If not prepared, this loss
of control
can result in possible serious

When drilling hard, smooth
surfaces,
use a center
punch to mark the desired hole location.
This will
prevent the drill bit from slipping
off-center
as the hole
is started.

When drilling metals,
use a light oil on the drill bit to
keep it from overheating.
The oil will prolong the life of
the bit and increase the drilling action.
