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
center position. The trigger will not work while the
control switch is in the center 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.
Drilling
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
surface and apply firm pressure.
To start a selfeed bit, run the threaded feed screw
into the work by flicking the trigger switch, permitting
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 center of the hole
to be drilled with a center punch to give the bit 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
to clear chips from the flutes.
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.
APPLICATIONS
WARNING
To reduce the risk of electric shock,
check work area for hidden pipes
and wires before drilling or driving screws.
Drilling in Wood, Composition Materials
and Plastic
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.
Drilling in Metal
When drilling in metal, select the drill operating mode.
Use high speed steel twist drills or hole saws. Use a
center 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.
Drilling in Masonry
When drilling in masonry, select the hammer-drill
operating mode. Use high speed carbide-tipped
bits. Drilling soft masonry materials such as cinder
block requires little pressure. Hard materials like
concrete require more pressure. A smooth, even
flow of dust indicates the proper drilling rate. Do not
let the bit spin in the hole without cutting. Do not use
water to settle dust or to cool bit. Do not attempt to
drill through steel reinforcing rods. Both actions will
damage the carbide.
Overloading
Continuous overloading may cause permanent damage
to tool or battery pack.
MAINTENANCE
WARNING
To reduce the risk of injury, always
unplug the charger and remove the
battery pack from the charger or tool before
performing any maintenance. Never disassemble
the tool, battery pack or charger. Contact a
MILWAUKEE service facility for ALL repairs.
Maintaining Tool
Keep your tool, battery pack and charger in good
repair by adopting a regular maintenance program.
Inspect your tool for issues such as undue noise,
misalignment or binding of moving parts, breakage of
parts, or any other condition that may affect the tool
operation. Return the tool, battery pack, and charger
to a MILWAUKEE service facility for repair. After six
months to one year, depending on use, return the
tool, battery pack and charger to a MILWAUKEE
service facility for inspection.
If the tool does not start or operate at full power with
a fully charged battery pack, clean the contacts on
the battery pack. If the tool still does not work prop
-
erly, return the tool, charger and battery pack, to a
MILWAUKEE service facility for repairs.
WARNING
To reduce the risk of personal in-
jury and damage, never immerse
your tool, battery pack or charger in liquid or
allow a liquid to flow inside them.
Cleaning
Clean dust and debris from vents. Keep handles
clean, dry and free of oil or grease. Use only mild
soap and a damp cloth to clean, since certain clean-
ing agents and solvents are harmful to plastics and
other insulated parts. Some of these include gasoline,
