maximum operator protection.

The main blade guard can be hinged up by loosening the lock bolts on front of the
guard. An interlock switch locks out the power to the saws until the hinged guard is back
in place and the bolts are tightened completely. Disconnect the air supply and move the
blades forward manually exposing the blades Follow the instructions on page 4, Blade

Cutting:

Cutting: (see Diagram “J” and “K”)
A fixed Double Mitre Saw, such as the DMC70 operates by making two 45

cuts at one time. The machine “V”

notches the piece of material between the two blades. To make the first cut on a stick length;
1. Feed the material to the centerline of the machine so that

ONLY

ONLY the left blade makes a trim cut. Be careful

not to overfeed beyond the centerline of the machine, as the piece can be hit with the right blade, possibly
throwing the unclamped piece into the saw blade, causing damage.

2. After making the trim cut, feed the material (now with a 45

mitre cut) to the stop at the desired length.

When using the Vision Gage, slide the moulding to the desired inside dimension, sighting down the line to the inside

of the rabbet of the moulding.

Move outside stop to same position and lock (see Diagram “K”).

3. Continue to feed length to stop as above, and make double mitre cuts until length is used.
4.

RULE OF DOUBLE MITRE CUTTING

RULE OF DOUBLE MITRE CUTTING—If the piece to be cut cannot be held on both sides

both sides

both sides of the blade,

do not cut it!!!

Minimum cut length on the DMC70A and DMC70M is 5 1/2” on the point to point dimension
