CTD CM325R, Instruction Bulletin & Maintenance Manual, Page: 11 / 34

Hand Operated Machines and Cutting Speed:
The blade is rotating at approximately 3700 RPM. When moving the blade through the material, the blade must
NEVER
be allowed to dwell in the work. If fine finishes are required:
1. Use a sharp blade. Do Not Force the Cutting Action, causing the motor to stall.
2. Use a
constant, even pressure
when cutting through material.
Spring Return:
Each sawhead is equipped with a drawbar return spring. The function of the spring is to return the sawhead to the
rest position upon release of the handle.
Do not adjust the spring pressure. If the spring breaks, Replace It
Immediately!
Make sure spring is attached properly (see Diagram “D” on Page No. 8) and
Never use a hand
operated machine without the return spring in place.
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 and Vertical Clamps. The Horizontal Clamp pushes the material backwards against the
rear fence and is mounted in the keyways of the base. A Vertical Clamp holds the material down, against the table base, and
is mounted through and on top of the fence bracket. Both clamps are offered as optional extras and are highly recommended.
If you purchased your machine with an Air Downfeed of the saw, the clamps are actuated prior to activating saw head by
depressing the Foot Valve. An Anti-Tie Down, Two Hand Control drives down the sawhead. If clamps are purchased using
a hand operated machine, then the clamps will move into position by pulling the saw head down slightly. This releases the
Automatic Valve (AV) to supply air to the clamps.
Be careful not to overtighten clamp cylinder bracket on the
cylinder. This will cause irregular function of the cylinder.

preset angle settings. The preset angle settings are 45

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.
