ADJUSTING THE AUXILIARY HANDLE ASSEMBLY
See Figure 9, page ii.
• Loosen the auxiliary handle assembly by turning the
knob counterclockwise.
• Rotate the auxiliary handle assembly to the desired
location.
• Tighten the auxiliary handle assembly securely by turn-
ing the knob clockwise.
ADJUSTING THE DEPTH STOP ROD
See Figure 10, page ii.
• Lock the switch trigger by placing the direction of rota-
tion selector in the center position.
• Loosen the auxiliary handle assembly by turning the
knob counterclockwise.
• Adjust the depth stop rod so that the drill bit extends
beyond the end of the rod to the required drilling depth.
• Tighten the auxiliary handle assembly by turning the
knob clockwise.
TWO-SPEED GEAR TRAIN (HI-LO SWITCH)
See Figure 11, page ii.
• Select LO (1} speed for applications requiring higher
power and torque.
• Select HI (2} speed for fast drilling or driving
applications.
NOTICE:
Never change speeds while the tool is
running. Failure to obey this caution could result in
serious damage to the drill.
ADJUSTABLE TORQUE CLUTCH
See Figure 12, page ii.
This product is equipped with an adjustable torque clutch
for driving different types of screws into different materi-
als. To use the torque settings, rotate the mode selector to
the screw (_-,-) setting. (The hammer mode ((=..)
and drill mode (*._) are for full torque operations.) The
proper setting depends on the type of material and the
application.
ADJUSTING TORQUE
See Figure 12, page ii.
Use carbide-tipped bits and select hammer mode when
drilling in hard materials such as brick, concrete, etc.
Use carbide-tipped bits and select drill mode when drilling
in materials with hard, brittle surfaces such as tile, etc.
Use twist drills, hole saws, etc. and drill mode when
drilling in soft materials.
Rotate the adjustment ring to the proper torque setting for
the type of material and size of screw you are using.
= 1 - 4 For driving small screws
= 5 - 8 For driving screws into soft material
= 9 - 12 For driving screws into soft and hard
materials
= 13 - 16 For driving screws into hard wood
= 17 - 23 For driving large screws
= *,_'q For heavy drilling
DRILLING/DRIVING SCREWS
See Figures 12 - 13, page iii.
A level is located on the top of the motor housing to help
keep the drill bit level during use.
• Install the auxiliary handle.
• Rotate mode selector to the screw (_-_-,)setting.
• Check the direction of rotation selector for the correct
setting (forward or reverse).
• Use LO (1} speed for high torque applications and
HI (2} speed for fast drilling or driving applications.
Refer to Two-Speed Gear Train and Adjusting Torque.
• Secure the workpiece in a vise or with clamps to keep
it from turning as the bit rotates.
• Hold the drill firmly and place the bit at the point to be
drilled, or where the screw is to be driven.
A
WARNING: Do not drive a screw where there is
likely to be hidden wiring behind the surface. Con-
tact with a "live" wire will make exposed metal parts
of the tool "live" and possibly shock the operator.
If you must drive a screw where hidden wire may
be present, always hold tool by insulated gripping
surfaces (handle) when performing the operation to
prevent a shock to the operator.
Depress the switch trigger to start the drill.
Move the bit into the workpiece, applying only enough
pressure to keep the bit cutting or driving the screw.
Do not force the drill or apply side pressure to elongate
a hole. Let the tool do the work.
