ASSEMBLY

NOTE: Many of the illustrations in this manual show only portions of the compound miter saw. This is intentional so that we can clearly show points being made in the illustrations. Never operate the saw without all guards securely in place and in good operating condition.

DUST GUIDE

See Figure 9.

Insert the dust guide inside the exhaust port in the upper blade guard. Turn the guide so that the open end is facing down.

DUST BAG

See Figure 10.

A dust bag is provided for use on your miter saw. It fits over a dust guide or exhaust port. Then, squeeze the two metal clips to open the mouth of the bag and slide it on the exhaust port. Release the clips. The metal ring in the bag should lock in between the grooves on the exhaust port. To remove the dust bag for emptying, simply reverse the above procedure.

NOTE: For efficient operation, empty the dust bag before it is half full. This will permit better air flow through the bag.

INSTALLING THE WORK CLAMP

See Figure 11.

WARNING:

In some operations, the work clamp assembly may interfere with the operation of the blade guard assembly. Always make sure there is no interfer- ence with the blade guard prior to beginning any cutting operation to reduce the risk of serious personal injury.

The work clamp provides greater control by clamping the workpiece to the miter table. It also helps to prevent the workpiece from creeping toward the saw blade. This is very helpful when cutting compound miters. Depending on the cutting operation and the size of the workpiece, it may be necessary to use a C-clamp instead of the work clamp to secure the workpiece prior to making the cut. The work clamp can be installed and used on either side of the blade.

To install the work clamp:

Place the work clamp shaft in one of the holes located behind the sliding miter fence.

NOTE: Align the pin on the work clamp shaft with the slot in the hole.

Rotate the knob on the work clamp to move it up or down as needed.

NOTE: The work clamp has a quick release lever that makes positioning of the work clamp effortless. Loosen the clamp then push the button on the side of the work clamp to quickly release the workpiece.
