The saw movement is controlled by depressing the two-hand anti-tie down control buttons. Once the clamps are
actuated via the foot switch, the two-hand buttons are depressed. The buttons must be held down throughout the saw
cutting cycle. The stroke of the saw heads can be reversed at any time by releasing the two-hand buttons. The selec-
tor switch can be used to operate only the left saw, only the right saw, or both. The selector switch “left” will only allow
the two-hand buttons to operate the left saw. The selector switch “right” will only allow the two-hand buttons to
operate the right saw. Selector switch “both” allows the two-hand control to operate the left saw and then the right
saw, to complete a cycle.

The forward speed of the left blade is controlled by the left Speed Control Valve, P/N 70 B3P60. The forward
speed of the right blade is controlled by the right Speed Control Valve, P/N 70B3P60. Both are located in the two-
hand button enclosure, located in the front of the machine. An easy way to remember is the
left valve controls the left
saw, and the right valve controls the right saw.

Horizontal manual clamps are supplied standard on the hand operated DMC70M and two Vertical Air Clamps are
supplied standard on the pneumatic version, the DMC70A. These clamps help hold the material in place when the saw
blades are cutting the material. If clamps are not used, the operator
MUST HAND HOLD THE MATERIAL. For the
hand operated DMC70M, the horizontal clamp pad or shoe needs to be adjusted so that it sits about 1/8” away from
the inside or rabbet of the material. When pulling the saw forward, the clamp will move forward to contact material and
push it towrds the front fences. The vertical clamps, on the DMC70A are controlled by two 4-Way Valves located in
the control panel on the lower right front side of the machine. The clamps are actuated by a foot switch when the two-
hand control buttons are depressed. A manual shut-off switch for the vertical air clamps is provided.
