WARNING:
Do not hold the chuck sleeve with one hand and use
the power of the drill to tighten the chuck jaws on the
drill bit. The chuck body could slip in your hand, or your
hand could slip and come in contact with the rotating
drill bit. This could cause an accident resulting in serious
personal injury.
 To remove bits, lock the switch trigger and open the
chuck jaws.
 The bit provided with the drill can be placed in the storage
area, located on the base of the drill.
INSTALLING/REMOVING BELT CLIP
See Figure 6, page 11.
The belt clip may be installed on either side of the housing.
 Align the hole in the belt clip with the hole in the housing.
 Install the screw to secure the belt clip in place.
 To uninstall, remove the screw then remove the belt clip.
TWO-SPEED GEAR TRAIN (HI-LO SWITCH)
See Figure 7, page 11.
 Select low speed (1) for applications requiring higher
power and torque, such as driving screws and drilling in
metal.
 Select high speed (2) for fast drilling or driving applications,
for drilling in wood or masonry, and for hammer drilling.
NOTICE:
Never change speeds while the tool is running. Failure
to obey this caution could result in serious damage to
the drill.
• Lag screws up to 3/8 in. dia. by 1-1/2 in. long
• Hole saw up to 2 in.
• Spade bits up to 1-1/2 in.
• Drill bits up to 1/2 in.
• Drilling into metal
• Concrete screws
• Deck or wood screws up to 3 in.
• Self tapping screws
• Deck or wood screws up to 2 in.
• Small screws or delicate work that requires more control
• Drilling into masonry and concrete.
OPERATION
APPLICATION
NOTE: If you have difficulty changing from one gear range
to the other, turn the chuck by hand until the gears engage.
QUICK MODE SELECTOR
See Figure 8, page 11.
The Quick Mode Selector allows you to quickly switch from
drill mode to drive mode.
Drill mode should be used for drilling and other heavy duty
applications. Drive mode should be used for driving screws.
Hammer mode should be used for hammer drilling.
Using the chart, select the option that best matches the type
of bit, fastener, and material you will be using.
 Choose your APPLICATION.
 Choose the correct SPEED: (1/LOW or 2/HIGH)
 Choose the correct MODE: (DRIVE, DRILL, or HAMMER)
ADJUSTING TORQUE
See Figure 9, page 11.
When using the drill-driver for various driving applications,
increasing or decreasing the torque helps prevent the
possibility of damaging screw heads, threads, workpiece,
etc. In general, torque intensity should correspond to the
screw diameter. If the torque is too high or the screws too
small, the screws may be damaged or broken.
The torque is adjusted by rotating the torque adjustment ring.
The torque is greater when the torque adjustment ring is
set on a higher setting. The torque is less when the torque
adjustment ring is set on a lower setting.
The proper setting depends on the type of material and the
size of screw you are using.
