Removing Material From the Blade:
If the machine is stalled while cutting, immediately shut saw off and disconnect power.
NEVER attempt to
free the blade while the motor is still on.
If a piece is bound on the blade, do not attempt to raise the blade
out of the material. Instead, tap the piece down on both sides of the blade with light pressure until the piece
has freed the blade.
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”).
Diagram “G” Diagram “F”
Check your material for squareness using a 90 degree square. Material that is out of square will move when it is
cut, causing irregular mitres. (See
“Irregular Mitres” on Page No. 16.) Additional tooling may be required.
Consult factory for more information.
Cutting Wood:
While wood is generally soft and simpler to cut than aluminum, it requires that the material be held in place
as the blade passes through the material. CTD suggests using a Carbide Blade with Alternate Top Bevel (AT)
for lighter wood sections and picture frame mouldings. This type of blade gives the finest of finishes. No
ONE
blade will cut all materials perfectly. High lacquers or mica mouldings require a special modified blade
for best results. Consult factory.
Never use a wood blade to cut aluminum
, as it will chip and fracture the
carbide tips of the blade.
Cutting Aluminum:
As with cutting any material, it is important that aluminum be clamped properly. Precision blades are
required for accurate cutting. CTD suggests and uses a Triple Chip Grind on all its non-ferrous Carbide
Blades. When cutting aluminum, or other non-ferrous materials, it is essential that the blades be lubricated
with a Sawblade Lubrication System or other blade lubricating system for the finest finish. See “
Sawblade Lubri-
cation System” or “CTD Biolubrication System” on Page No. 11 for more details.
Abrasive Cutting:
When abrasive cutting, cut at the fastest speed rate the motor will allow.
Do not stall the motor
. Blade will
glaze as a result of too slow a feed rate, or too hard a composition. Abrasive blades may break due to
movement of the work, twisting of the blades, or glazing of the cutting edge. Seldom do abrasive blades
break because of too fast a feed rate. The thinnest section of material should be presented to the blade.
For example, when cutting 1” x 2” stock, stand the piece up so the 1” edge is cut.
Abrasive blades have
the tendency to wander when lengths of less than 1/2” are cut. The burr will normally be heaviest on the cut
piece. To eliminate this condition, the cut pieces should be clamped.
