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

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°.
Center

line
the vise and fence should be
positioned so the centerline
of the wheel hub is in line with

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

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.
