Roving Cutter Instructions
RC-1000
The RC-1000 cutter was designed to cut glass roving into short lengths of 1/2” to 4”, and dispense it into a
resin fan. When properly adjusted, the chopped glass will be spread out evenly from edge to edge of the
resin pattern. Also, the glass/resin mixture on the part will need a minimum amount of rolling.
AIR REQUIREMENTS
The RC-1000 requires 15 CFM of clean, filtered air at a minimum of 90 PSI to operate efficiently. The air
supply hose must have a minimum 5/16” inside diameter for a 25-foot hose. A longer hose may need a
larger inside diameter. Lower air pressures or smaller hose could result in poor operation.
OPERATION
To introduce roving to the cutter, double up the end of roving and insert into one of the three holes in the
feed bar on top of the cutter. The motor control knob on the bottom of the manifold assembly should be
opened about a full turn out. The blower control knob on the side should be about 1/2 turn out at the
beginneing. Pull trigger and glass will be dispensed into the resin fan. The blower control keeps air mov-
ing through the chopper cover to help keep it from plugging. By opening or closing the motor control knob,
the glass output will increase or decrease accordingly. Adjust both motor control and blower control to
produce the desired output and pattern.
ADJUSTMENTS
Idler Bearing: With glass roving in place, idler should hold glass against the anvil sleeve. Excessive
tension may cause the glass to wrap around the idler bearing. Adjustments are accomplished by loosen-
ing the idler bolt, rotating the eccentric nut and then retightening.
Air Motor: The air motor on your cutter is precision built and with proper care, under normal operation,
will last hundreds of hours of continuous use. It is important that this motor be lubricated at the end of
each working shift. Lubrication is best accomplished by removing the motor speed control valve, and
inserting 8 drops of a lightweight oil. Replace needle valve and run the cutter for approximately five sec-
onds. It is not necessary to cut glass curing this time. The clearances of this motor are extremely critical.
For this reason, it is advisable that the motor be sent to an authorized distributor for repair. The warranty
is void if this motor is opened by any except factory-authorized repair centers.
