If the bit binds, the motor housing braced against the
stud will hold the drill in position.

Shifting Speeds
Use the shift knob to select High (H) or Low (L) speed.
High speed (1,550 RPM) is the low torque setting.
Low speed (500 RPM) is the high torque setting.
under high and low speeds.
Always turn off the switch and shift speeds while the
tool is stopped. Never shift the drill while it is moving
or when it is under load.
Using Control Switch
The control switch may be set to three positions: for-
ward, reverse and lock. Due to a lockout mechanism,
the control switch can only be adjusted when the
trigger is not pulled. Always allow the motor to come
to a complete stop before using the control switch.
For Forward (clockwise) rotation, push the control
switch from the left side of the tool. Check the direc-
tion of rotation before use.
For Reverse (counterclockwise) rotation, push the
control switch from the right side of the tool. Check
direction of rotation before use.
To Lock the trigger, push the control switch to the
centre position. The trigger will not work while the
control switch is in the centre locked position. Always
lock the trigger or remove the battery pack before
performing maintenance, changing accessories,
storing the tool and any time the tool is not in use.
Starting, Stopping and Controlling Speed
These tools may be operated at any speed from 0
to full speed.
1. To start the tool, pull the trigger.
NOTE: An LED is turned on when the trigger is pulled.
2. To vary the driving speed, increase or decrease
pressure on the trigger. The further the trigger is
pulled, the greater the speed.
3. To stop the tool, release the trigger.

1. Before drilling, be sure the workpiece is clamped
securely. A poorly secured piece of material may
result in personal injury or inaccurate drilling. Use
backing material to prevent damage to the work-
piece during breakthrough. When drilling in light
gauge metal or wood, use a wooden block to back
up the material to prevent damage to the workpiece.
2.
When starting a hole, place the drill bit on the work
To start a selfeed bit, run the threaded feed screw
the bit to coast until the teeth contact the work sur-
face. Align the bit properly before proceeding. This
will reduce cocking and jamming when starting.
When drilling in metal, mark the centre of the hole
to be drilled with a centre punch to give the bit a
A
start and to prevent it from "walking." Lubricate the
drill bit with cutting oil when drilling iron or steel.
Use a coolant when drilling nonferrous metals such
as copper, brass or aluminum.
3.
Always apply pressure in line with the bit. Use
enough pressure to keep the drill biting, but do
not push hard enough to cause the bit to bind.
When using twist drill bits, pull the bit out frequently
When using selfeed bits, if the clutch slips, pull
the bit up very slightly and then push it toward the
workpiece. Repeat this several times.
4. Reduce pressure and ease the bit through the last
part of the hole. While the tool is still running, pull
the bit out of the hole to prevent jamming.
When using selfeed bits, decrease the drilling pres-
sure when the feed screw point breaks through the
workpiece. Proceed with steady, even pressure.
WARNING
and wires before drilling or driving screws.
Drilling in Wood, Composite
When drilling in wood, composition materials and
plastic, select the drill operating mode. Start the drill
slowly, gradually increasing speed as you drill. Use low
speeds for plastics with a low melting point.
When drilling in metal, select the drill operating mode.
Use high speed steel twist drills or hole saws. Use a
centre punch to start the hole. Lubricate drill bits with
cutting oil when drilling in iron or steel. Use a coolant
when drilling in nonferrous metals such as copper,
brass or aluminum. Back the material to prevent bind-
ing and distortion on breakthrough.
Continuous overloading may cause permanent damage
to tool or battery pack.
