WARNING
To reduce the risk of injury, wear
safety goggles or glasses with side
shields. Unplug the tool before
changing accessories or making
adjustments.
OPERATION
Step 4 - Adjusting the Blade -
Perpendicularity
If you remove the saw motor without making
sure that the factory-set adjustment screw
contacts the plate on the saw motor, then
the blade will not be perpendicular (90°) to
the workpiece, possibly resulting in inac-
curate cuts.
1. Unplug the tool.
2. To adjust for perpendicularity, loosen the
two mounting nuts on the front of the saw
motor. The adjustment screw is located
to the right of these nuts (Fig. 13).
3. Loosen the lock nut under the bracket.
Tighten or loosen the adjustment screw
depending on the angle adjustment
required. ONLY make slight adjust-
ments.
4. Tighten the lock nut, making sure the
screw is against the upright plate.
5. Tighten the two hex nuts to secure the
saw.
6. Plug in the tool and make a sample cut.
Repeat the procedure if necessary.
Selecting a Blade
A Combination/Rip blade is supplied with
the tool.
MILWAUKEE recommends using one of the
blades listed in “Accessories". These blades
will provide the best tool performance and
the best cut. Always keep blades clean and
sharp for the best performance. A dull or dirty
blade can bind and pinch, resulting in kick
back or a poor cut.
Changing Blades
1. Unplug the tool.
2. Remove the blade guard (see "Installing
the Blade Guard").
3. To remove the bolt from the spindle, use
the wrench provided with the tool to turn
the bolt counterclockwise while holding
in the spindle lock button.
Starting and Stopping the Motor
1. To start the saw motor, lift the switch up.
The switch will stay up until it is pushed
down.
2. To stop the saw motor, push the switch
down.
4. Remove the outer ange, blade, and
inner ange. Clean the spindle, anges,
bolt and blade to remove buildup of dust
and debris.
5. Replace the inner ange.
6. Install the blade with the arrow pointing
counterclockwise.
7. Replace the outer ange. Tighten the
bolt clockwise using the wrench pro-
vided while holding in the spindle lock
button.
8. Install the blade guard (see "Installing
the Blade Guard").
NOTE: It may be necessary to readjust
the rulers after changing or resharpening
blades (see “Adjusting the Rulers”).
WARNING
To reduce the risk of injury, make
sure the tool is OFF before plugging
in the tool.
Making the Cut:
1. Rotate the saw motor to the cross-cut-
ting position (Fig. 14). To rotate the
motor, pull out the indexing pins and
rotate the saw motor. Lock the indexing
pins into the preset holes on the saw
carriage. The pins are spring-loaded
and should snap into place.
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.

Cross-Cutting
A cross-cut is a vertical cut that must always
be done from the top to the bottom of a
workpiece.
MILWAUKEE recommends using the Hold
Down Bar Kit for frequent cutting of workpiec-
es thinner than 1/4" (see "Accessories").
The workpiece must be supported by a mini-
mum of two rollers. When using the Midway
Fence Kit , material must extend at least 4"
beyond the saw carriage on either side.
For easier cutting and best performance,
MILWAUKEE recommends using an Exten-
sion Kit when cross-cutting workpieces that
extend beyond the blade by 5' or more on
one side. Do not cross-cut workpieces that
exceed 8'.
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 bet-
ter suited for these applications.
WARNING
To reduce the risk of injury, do not
place hands on or under saw carriage
or in the path of the saw blade.
