ADJUSTMENTS
ADJUSTING THE AUXILIARY HANDLE
ASSEMBLY
See Figure 11.
Follow these steps to adjust the auxiliary handle assembly.
n Loosen the auxiliary handle assembly by turning the knob
counterclockwise.
n Rotate the auxiliary handle assembly to the desired
location.
n Tighten the auxiliary handle assembly securely by turning
the knob clockwise.
ADJUSTING DRILLING MODE
See Figure 12.
To adjust for type of drilling, slide adjustment button on top
of motor housing hammer mode or drilling mode. For your
convenience a hammer symbol and drill bit symbol have been
molded into the adjustment button.
WARNING:
The hammer drill has not been designed for reverse
hammering.
We recommend that you use carbide-tipped bits and select
hammer mode when drilling in hard materials such as brick,
tile, concrete, etc.
We recommend that you select normal drill mode when drilling
with twist drills, hole saws, etc., in soft material.
Pulse mode is activated when rear dial on top of drill is turned
to the circle icon and can be used at any RPM (high or low
speed). Numbers 1 through 6 on the same dial are the torque
settings.
VARIABLE TORQUE/PULSE
See Figure 12.
The adjustable torque is controlled by a dial on top of the drill
and numbered 1-6, with 1 being the lowest and 6 the highest.
Rotate the dial clockwise to increase torque. Always reduce
the torque setting when there is a risk of the bit grabbing,
such as at "break through." The "+"setting is the maximum
torque setting.
The pulse feature is used to help start holes without use of
a center punch. Pulse mode drilling allows for working with
damaged screw heads, countersinking screws in wood, un-
screwing very tight screws, and starting a drill bit on hard,
smooth surfaces.
The torque control dial is in the "pulse" mode when turned to
the full counterclockwise position.
ADJUSTING THE DEPTH GAUGE ROD
See Figure 13.
Follow these steps to adjust the depth gauge rod.
n Lock the switch trigger by placing the rotation selector in
the center position.
n Loosen the auxiliary handle assembly by turning the knob
counterclockwise.
