Operation - Milwaukee 0233-20 Operator's Manual

WARNING
To reduce the risk of injury:
Do not grasp the bit while the chuck is rotat
ing or while the bit is falling from the chuck.
Release the trigger as soon as the ratcheting
stops to avoid throwing the bit.
Installing Bits into Keyless Chucks
(Cat. No. 0233-20)
These tools are equipped with a hand-tightening
keyless chuck. Always unplug the tool before install-
ing or removing bits.

Sleeve
1. To open the chuck jaws, turn the sleeve in the
counterclockwise direction.
When using drill bits, allow the bit to strike the
bottom of the chuck. Center the bit in the chuck
jaws and lift it about 1/16" off of the bottom.
When using screwdriver bits, insert the bit far
enough for the chuck jaws to grip the hex of the bit.
2. To close the chuck jaws, hold the collar while
turning the sleeve in the clockwise direction.
Tighten securely.
Installing Bits into Keyless Chucks
(Cat. No. 0235-21)
These tools are equipped with a spindle-lock mech-
anism and a single-sleeve keyless chuck. Always
unplug the tool before inserting or removing bits.
1. To open the chuck jaws, turn the chuck sleeve
in counterclockwise direction.
2. To install a bit, open the chuck jaws slightly wider
than the bit. Center the bit in the chuck jaws and
lift it about 1/16" off of the bottom. Align the bit
as shown (Fig. 4).

3. To close the chuck jaws, turn the chuck sleeve
in clockwise direction (Fig. 5). Tighten securely.
Several detents will be felt as the chuck sleeve
is turned.

NOTE: If the spindle rotates when opening or closing
the chuck jaws, grasp the chuck and slightly rotate
back and forth to engage the spindle-lock mechanism.
The spindle will remain locked until the tool is turned
on. The spindle-lock mechanism will automatically
disengage when the tool is turned on.
WARNING
To reduce the risk of injury,
wear safety goggles or glasses with side
shields.
Chuck Removal
This tool is equipped with a threaded spindle to hold
the chuck. Before removing the chuck, unplug the
tool and open the chuck jaws. A left-handed thread
screw is located inside the chuck to prevent the
chuck from loosening when the tool is operated
in reverse direction. Remove the screw by turning
it clockwise. To remove the chuck, hold the tool
so that only the side of the chuck rests fi rmly and
squarely on a solid workbench. Insert the chuck
key or a chuck remover bar in one of the keyholes.
Turn the chuck so the key is at about a 30° angle
to the bench top and strike the key sharply with a
hammer so the chuck turns in a counterclockwise
direction (looking from the front of the tool). This
should loosen the chuck from the spindle which
has a right hand thread making it easy to remove
the chuck by hand.
NOTE: When replacing the chuck, always replace
the left hand thread screw in the chuck.

1. Remove the chuck from the drill following instruc-
tions (See "Removing the Chuck From the Drill").
Slip the double hex coupling (1) over the hex on
the drill spindle.
Loosen the clamping screws on the clamping
sleeve (2) and slip the sleeve onto the drill collar.
2. Slide the Right Angle Drive head (4) into the other
side of the sleeve and turn the drive head slightly
in either direction so the hexagonal hole in the
coupling (1) engages the hexagonal portion of
the spindle (3).
NOTE: Attaching the drill chuck to the side
marked "LOW" reduces the speed by 1/3, or
33%. Attaching the drill chuck to the opposite
side increases the speed by 50%.
3. When assembled, turn the Right Angle Drive
head to the desired position and tighten the
clamping screws to secure the unit. Thread the
chuck onto the Right Angle Drive spindle (5).
INSTALL CHUCK LOCKING SCREW.
Removing the Chuck From RAD
The chuck can be removed from the Right Angle
Drive Unit in the same manner it is removed from
the drill; however, ALWAYS REMOVE RIGHT
ANGLE DRIVE FROM THE DRILL BEFORE AT-
TEMPTING TO LOOSEN
THE CHUCK. This will pre-
vent damaging the drill's
gearing. Use the open
end wrench provided to
hold the Right Angle Drive
spindle before attempting
to loosen the chuck.

OPERATION

WARNING
To reduce the risk of injury,
always unplug tool before attaching or remov-
ing accessories or making adjustments. Use
only specifi cally recommended accessories.
Others may be hazardous.
WARNING
To reduce the risk of injury,
wear safety goggles or glasses with side shields.
Using Forward/Reverse Switch

Trigger
Reverse
1. For forward (clockwise) rotation, push the for-
ward/reverse switch to FWD as shown.
2. For reverse (counterclockwise) rotation, push
the forward/reverse switch to REV as shown.
Although an interlock prevents reversing the tool
while the motor is running, allow it to come to a
full stop before reversing.
WARNING
keep hands and cord away from the bit and
all moving parts.
Starting, Stopping and Controlling Speed
1. To start the tool, pull the trigger.
2. To stop the tool, release the trigger.
3. To vary the drilling speed, simply increase or
decrease pressure on the trigger. The further
the trigger is pulled, the greater the speed.
Locking Trigger
The lock button holds the trigger in the ON position
for continuous full speed use.

Lock button
1. To lock the trigger, hold the lock button in while
pulling the trigger. Release the trigger.
2. To unlock the trigger, pull the trigger and release.
The lock button will pop out.
WARNING
sion, electric shock and property damage,
always check the work area for hidden pipes
and wires before drilling.
Drilling
1. Before drilling, be sure the workpiece is clamped
securely. Use backing material to prevent dam-
age to the workpiece during breakthrough.
2. When starting a hole, place the drill bit on the
work surface and apply fi rm pressure. Begin
drilling at a slow speed, gradually increasing the
speed as you drill.
3. Always apply pressure in line with the bit. Use
enough pressure to keep the drill biting, but do
not push hard enough to stall the motor.
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.
Stalling
If the tool seems as if it is about to stall, maintain a
fi rm grip and reduce pressure slightly to allow the
bit to regain speed. If the tool does stall, release
the trigger immediately. Reverse the motor, remove
the bit from the work and start again. Do not pull
the trigger on and off in an attempt to start a stalled
drill. This can damage the drill.
