Angle Adjustments on Model A500M:
To change the angle:
Clamping and Work Slippage:
The work must never be allowed to move or vibrate as it is being cut. When the work is positioned against a stop,
it must be clamped either by hand holding or by pneumatic air clamps. Never allow unclamped work between the
blade and the stop, as the blade can grab the material and throw it—thereby causing damage to the blade, the
machine, and possibly harming the operator. CTD offers both Horizontal Air Vises and Vertical Clamps. The
Horizontal Air Vise pushes the material backwards against the rear fence. Vertical Clamps hold the material
down, against the table base. The clamps are actuated prior to the saw head. by pushing a hand valve. Check
your material for squareness using a 90° square. Material that is out of square will move when it is cut, causing
irregular mitres. (See “IRREGULAR MITRES” on Page No. 14.) Additional tooling may be needed. Consult
factory for more information.
Cutting the Material:
The material to be cut (both the incoming pieces and the cut pieces) must lay flat on the table base, or the blade
may bind the material. THIS CAN DAMAGE THE BLADE OR THROW THE CUT PIECE OUT OF THE
SAW, POSSIBLY HARMING THE OPERATOR (see Diagram “F”).

1. Pull back spring loaded mitre locking pin & handle assembly & rotate to the right or left. This prevents the
pin from engaging. Mitre lock pin & handle will lock in the open position.
2. Make sure mitre lock down bolt (located in the center of the pivot bracket-see Diagram “D” & “E”) is
loosened.
3. To lock in at preset angles, rotate sawhead and disc near the desired angle aligning with zero mark on base.
4. Turn mitre locking handle to center position, and the spring loaded pin & handle will automatically engage
into preset angle settings. The preset angle settings are 45

, 30
°
, 22 ½
°
, 15
°
, 0
°
on both sides of the
centerline or zero point. Do not let the spring loaded mitre locking pin & handle engage in several
degree settings as you rotate the mitre base disc. This will cause excess wear on preset angle settings.
5. For all angles that are not preset, follow instructions under #1 to lock handle in the open position.
Simply align degree quadrant on disc with zero mark on base and tighten down intermediate mitre lock
handle located in base.
