Milwaukee 6480-20 Operation, Adjusting the Blade Perpendicularity, Cross-Cutting, Changing Blades

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.

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.

Cross-Cutting

A cross-cut is a vertical cut that must always be done from the top to the bottom of a workpiece.

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

OPERATION

MILWAUKEE recommends using the Hold Down Bar Kit for frequent cutting of workpiec- es thinner than 1/4" (see "Accessories").

WARNING

To reduce the risk of injury, wear safety goggles or glasses with side shields. Unplug the tool before changing accessories or making adjustments.

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.

4.Remove the outer flange, blade, and inner flange. Clean the spindle, flanges, bolt and blade to remove buildup of dust and debris.

5.Replace the inner flange.

6.Install the blade with the arrow pointing counterclockwise.

7.Replace the outer flange. 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.

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.

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

To reduce the risk of injury, do not place hands on or under saw carriage or in the path of the saw blade.

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 bet- ter suited for these applications.
