Instruction manual

Guarding:
The belt drive is completely enclosed with a fabricated guard. The blade guard coversand the machine shield must
be down and closed for the machine to cycle through the cut. The left and right hinging doors must be closed and
locked before any cutting should take place. The operator must not be exposed to an unguarded blade. The
hands or fingers must never be allowed to come in close proximity to the blade—for certain, never under the
blade. Cut off pieces that are short must be removed with a piece of wood or an air blast.
Fences or Back Stops:
The CTD A500 saw is provided with accurately machined fences. This feature allows the operator to easily adjust
the position of the fences for the best, safe condition. (see “Position of Work” below). It is essential that all fences be
adjusted front to back, in the same plane. The fences must also be adjusted so that the shortest cut off piece will not
be able to slip between the blade and fence. Likewise, short pieces must not be allowed to slip between the blade and
the slot in the base. Danger to the operator and blade may result if either of these situations are allowed to occur.
Position of Work:
The fences must be set so that the centerline of the work is either to the front or on the centerline of the blade. If the
work is cut on, or to the front of the centerline of the blade, the machine is absolutely safe—even if the motor is
overloaded and the blade is stalled. The action will drive the work down and to the rear. If the material is set behind
the centerline, there is a chance of the material being lifted up by the cutting action.
Material Not Flat on Table:
It is necessary that the material lay flat on the table. If long material is to be cut off, the conveyor or work supports
must be in exact alignment with the top of the table. If the stock supports are above or below the table, the material
will bind the blade, slip or rise up as it is being cut. All back stops or fences must be in the same plane, or when the
material is cut, it may tend to slip or move, causing inaccurate cuts.
Clamping and Work Slippage:
The work must never be allowed to slip as it is being cut. Due to the wide variety of work, clamping requirements
vary considerably.
Clamping:
In the cutting of aluminum extrusions, often times thin legs or projections must be properly supported to avoid
vibrations. Also, round materials must be securely clamped. Jaws for the vise clamps may be shaped to fit the
contours of the individual piece, thus eliminating clamping and feeding problems. The rear jaws of the A480E vises
have three positions. The front and rear jaws can be set 12” apart at the widest setting. The positioning of the front
jaws is limited by 3” travel of the cylinder shafts. However, they are adjustable another 3” in slots using lock down
bolt. (See Diagram C #123 on Page No. 28).
