2. Loosen the carriage lock and allow the saw motor
to raise to the top of the tool. The saw motor is
attached to the counterbalance cable and should
raise to the top of the guide tubes by itself. If it
does not, see “Lubricating Guide Tubes” in the
Maintenance section.
3. Plug in the tool.
4. Place the workpiece on the rollers. Do not to
drop the material; this may knock the rollers out
of alignment or damage the rollers.
Slide the workpiece to the desired position using
the cross-cut ruler as a measure.
5. Start the motor and allow it to reach full speed
before beginning the cut.
6. When the motor has reached full speed, slowly
pull the saw motor down through the workpiece,
keeping your hand on the handle.
7. Once the cut is complete, turn the tool off and
wait for the blade to come to a complete stop.
8. Raise the saw motor and allow the saw motor to
return to the top of the guide tubes.
9. Tighten the carriage lock.
NOTE: A coasting blade can mar the edge of a
freshly cut workpiece.

WARNING Do not cut a workpieces
that has a width smaller than that of the saw
carriage. Proper support for the workpiece
must be maintained to insure safety. When the
carriage moves over the workpiece, it would
be impossible to safely support the workpiece
for the cut. Use a tool better suited for these
applications.

Rip Cutting
A rip cut is a horizontal cut that can be done from
the LEFT TO THE RIGHT or from the RIGHT TO
THE LEFT, but the work piece must always be
moved through the saw in the direction of the arrow
on the saw motor.
MILWAUKEE recommends using the Hold Down
Bar Kit for frequent cutting of workpieces thinner
than 1/4" (see "Accessories").
The minimum length recommended for rip cuts is
2-1/2' (work supported by four rollers). The same
size applies if you use the Midway Fence Kit.
For easier cutting and best performance,
MILWAUKEE recommends using the Extension
Kit when rip-cutting workpieces longer than 6'
(see "Accessories"). Do not rip-cut workpieces
that exceed 8'.
1. Select ripping from the left or right, based on
preference. Rotate the saw motor to the ripping
position (Fig. 15). To rotate the motor, pull out
the indexing pins and rotate the saw motor. Lock
the indexing pins into the preset holes in the saw
carriage. The pins are spring-loaded and should
snap into place. Be sure to shield bystanders
from the tool.
2. Select the saw height based on your workpiece,
following the measure on the rip ruler.
3. Tighten the carriage lock securely.
4. Plug in the tool.
5. Start the motor and allow it to reach full speed
before beginning the cut.
6. Place the workpiece on the rollers. Do not to
drop the material; this may knock the rollers out
of alignment or damage the rollers.

WARNING To reduce the risk of injury,
ripping must always be done by moving the
workpiece through the saw in the direction of
the arrow on the saw motor.
7. When the motor has reached full speed, slowly
move the workpiece through the saw in the direc-
tion of the feed arrow on the saw motor. Avoid
placing your hands, clothing or body parts under
the saw carriage. Do not look directly down the
line of cut because dust and debris are gener-
ated during operation. Do not use push sticks.
8. After the cut is completed, turn the tool off and
wait for the blade to come to a complete stop.
WARNING To reduce the risk of
injury and damage to the tool, do not use
push sticks. Push sticks or the workpiece
can kick back, cause the blade to pinch, or
become caught in the blade and be thrown
from the tool.
WARNING To reduce the risk of injury,
always shield bystanders from the tool. Never
look down the line of cut because dust and
debris are generated during operation.
MAINTENANCE
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.
WARNING To reduce the risk of
injury, always unplug your tool before
performing 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.
Lubricating Guide Tubes
The saw carriage should raise itself from the bottom
to the top of the guide tubes. However, if the tubes
become caked with dust or debris, the saw carriage
may get stuck or it may not slide smoothly. Periodi-
cally clean the guide tubes with a damp cloth, fol-
lowing the directions under "Cleaning". Then, use a
dry lubricant such as PTFE or spray silicone. Other
lubricants will cause dust and debris to collect on
the tubes, contaminating the bearings.
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.
9. Pull the scrap material and the fi nished work-
piece away from the tool.
10. Return the saw carriage to the uppermost
position on the guide tubes.
11. Tighten the carriage lock.
NOTE: When done ripping, return the carriage to
the cross-cut position.
Making Cuts Less than 1"
When making cuts that are less than 1", the chat-
ter guard (located inside the blade guard) must be
on the workpiece and not on the cut-off piece. If
the chatter guard is on the cut-off piece, it will jam
on the workpiece and prevent the carriage from
continuing through the cut. If the saw jams, turn
the tool OFF and wait for the blade to stop. Then
back the saw out of the cut.
Lock-Off Feature
Unplug the tool before installing the padlock. There
is a hole in the switch through which a padlock (not
supplied with tool) will fi t to lock the tool when it is
not in use. Use a padlock with a 1-1/2" shackle,
5/16" diameter (such as the Master Lock 1KALJ).
Maintaining Tools
Keep your tool in good repair by adopting a regular
maintenance program. Before use, examine the
general 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, bro-
ken 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
