Adjusting the Depth of Cut
The depth adjustment bolt can be adjusted to
change the depth of cut. When adjusted properly,
the depth adjustment bolt prevents the cut-off wheel
from contacting the surface under the base during
cutting. Cut-off wheels wear down as they are used
and the depth of cut may need to be increased.
To adjust the depth of cut:
1. Unplug the tool.
2. Use the wrench provided to loosen the hex nut.
3. Adjust the depth adjustment bolt to the desired
height.
4. Tighten the hex nut.
Supporting the Workpiece and Adjusting the
Vise and Fence System
The adjustable vise and fence system holds the
workpiece in the desired position. The vise plate
and fence can be moved backward or forward
and can be adjusted to any angle between 90°
and 45°.
When adjusting the system,
the vise and fence should be
positioned so the centerline
of the wheel hub is in line with
or behind the centerline of the
workpiece, toward the rear of
the tool. The workpiece should
be resting fl ush with the base
of the cut-off machine.
To adjust the fence:
1. Use the wrench provided to
loosen (counterclockwise)
the two fence bolts.
2. Adjust the position and angle
of the fence as desired.
3. Securely tighten (clock-
wise) the two fence bolts.
To adjust the vise:
1. Pull the lock lever back.
2. Pull the vise handle out.
3. Place the workpiece fl at on the base and against
the fence.
4. Push down the lock lever.
5. Slide in the vise handle to press the vise plate
againce the workpiece.
6. Turn the vise handle clockwise to tighten the vise
plate against the workpiece.

MAINTENANCE
WARNING To reduce the risk of injury,
always unplug your tool before per-
forming any maintenance. Never disas-
semble the tool or try to do any rewiring
on the tool’s electrical system. Contact a
MILWAUKEE service facility for ALL repairs.
Maintaining Tools
Keep your tool in good repair by adopting a regular
maintenance program. Before use, examine the gen-
eral condition of your tool. Inspect guards, switches,
tool cord set and extension cord for damage. Check
for loose screws, misalignment, binding of moving
parts, improper mounting, broken parts and any
other condition that may affect its safe operation. If
abnormal noise or vibration occurs, turn the tool off
immediately and have the problem corrected before
further use. Do not use a damaged tool. Tag damaged
tools “DO NOT USE” until repaired (see “Repairs”).
Under normal conditions, relubrication is not neces-
sary until the motor brushes need to be replaced.
After six months to one year, depending on use,
return your tool to the nearest MILWAUKEE service
facility for the following:
• Lubrication
• Brush inspection and replacement
• Mechanical inspection and cleaning (gears,
spindles, bearings, housing, etc.)
• Electrical inspection (switch, cord, armature, etc.)
• Testing to assure proper mechanical and electrical
operation
WARNING To reduce the risk of injury,
electric shock and damage to the tool,
never immerse your tool in liquid or allow a
liquid to fl ow inside the tool.
Cleaning
Clean dust and debris from vents. Keep the tool
handles clean, dry and free of oil or grease. Use
only mild soap and a damp cloth to clean your tool
since certain cleaning agents and solvents are
harmful to plastics and other insulated parts. Some
of these include: gasoline, turpentine, lacquer thin-
ner, paint thinner, chlorinated cleaning solvents,
ammonia and household detergents containing
ammonia. Never use fl ammable or combustible
solvents around tools.
Repairs
If your tool is damaged, return the entire tool to the
nearest service center.

Raising and Lowering the Head
The head must be locked down for transporting
and storing the tool.
To unlock, press head down and pull out the lock
down pin.
To lock, press head down and push in the lock
down pin.
Removing and Installing Cut-Off Wheels
Use only MILWAUKEE 14" Abrasive Cut-Off
Wheels, 3/32” thick with this tool. Before operating
the tool, make sure the wheel is in good condition
as described in the “Specifi c Safety Rules”.
To change wheels:
1. Unplug the tool.
2. Raise the head.
3. Push up the lower guard to expose the hex bolt.
Press in the spindle lock button and use the
wrench provided to loosen the hex bolt (coun-
terclockwise).
4. Remove the hex bolt, washer, outer fl ange and
cut-off wheel. Do not remove the inner fl ange.
5. Check the inner and outer fl anges to be sure
they are in good condition. Remove any nicks,
burrs, and debris from the mounting hardware,
which could cause uneven cutting pressure and
result in wheel damage.
6. Install the cut-off wheel, outer fl ange, washer,
and hex bolt onto the spindle, as shown.
7. Press in the spindle lock button while using the
wrench provided to tighten the hex bolt (clockwise).
8. Release the lower guard.
9. Before starting a cut, step back from the tool
and make a trial run to confi rm that the wheel
is in good condition. Before using a new cut-off
wheel, run the tool for at least 3 minutes. Before
starting work, run the tool for at least 1 minute.
Selecting a Workpiece
The MILWAUKEE Abrasive Cut-Off Machine is
designed to cut steel and concrete. It is not recom-
mended for cutting wood. Do not attempt to install
a saw blade on the tool.
Starting and Stopping the Tool
1. Plug in the tool.
2. To start the tool, pull the trigger.
3. To stop the tool, release the trigger.
Making a Cut
1. Unplug the tool.
2. Select a cutting angle and position the fence and
vise to support the workpiece (see “Supporting
the Workpiece and Adjusting the Vise and Fence
System”).
3. Plug in the tool.
4. Before starting a cut, step back from the tool
and make a trial run to confi rm that the wheel
is in good condition. Before using a new cut-off
wheel, run the tool for at least 3 minutes. Before
starting work, run the tool for at least 1 minute.
5. Allow the motor to reach full speed. Slowly lower
the wheel into the workpiece.
NOTE: Always start the cut gently; do not bang
or bump a wheel when starting the cut. For the
safest and most effi cient cutting, make sure
that the cut-off wheel contacts the center of the
workpiece.
6. When the cut is complete, raise the wheel com-
pletely from the workpiece before releasing the
trigger and allowing the motor to stop.
Trigger Hole Lock-Off
The trigger hole allows the user to insert a pad-
lock. This prevents the tool from being started
unintentionally.
3. Push up the lower guard to expose the hex bolt.
Press in the spindle lock button and use the
wrench provided to loosen the hex bolt (coun-
terclockwise).
4. Remove the hex bolt, washer, outer fl ange and
cut-off wheel. Do not remove the inner fl ange.
5. Check the inner and outer fl anges to be sure
they are in good condition. Remove any nicks,
burrs, and debris from the mounting hardware,
which could cause uneven cutting pressure and
result in wheel damage.
6. Install the cut-off wheel, outer fl ange, washer,
and hex bolt onto the spindle, as shown.
