Setup Setup 1. Engage trigger lock. 3. Insert glass strands into feed. 2. Install cutter: 4. Adjust anvil to blade tension: a. If necessary, use a crescent wrench to adjust pivot (541) so that it is parallel to gun front end and the open end points to the front of the gun. See FIG. 3. 541 542 630 a. Release lockdown (AG). See FIG. 1 on page 4. b. Adjust tension knob (AF) as desired. c. Tighten lockdown (AG). d. Release idler lock down screw (AN). e.
Operation Operation Cutter Assembly 1. Do a bag check to establish a baseline for the current cutter output. a. Weigh a bag. AH AC b. Dispense glass into the bag for 15 or 30 seconds depending on the output. c. Weigh the bag to determine glass output. This is your fiberglass output baseline. 2. Add another strand of roving to the cutter inlet. 3. Engage trigger lock. AG AF AJ To prevent skin injection, engage the trigger lock before adjusting cutter motor. FIG.
Operation Adjust Cutter Speed When dispensing a material and glass mixture, the speed at which the cutter spins can be adjusted to ensure the correct ratio of glass to dispensed material. NOTE: It may be possible to prevent premature anvil and blade wear by slowing the cutter speed and adding an additional strand of roving. See Premature Blade or Anvil Wear on page 7. Adjust Anvil to Cutter Head Tension NOTICE More tension leads to the anvil and blades wearing out faster.
Operation Adjust Anvil to Idler Tension Adjust Cutter Air Pressure To adjust the anvil (AC) to idler (AJ) tension, the idler position can be adjusted. See FIG. 4 on page 7. Adjust the incoming air pressure according to the table below. 1. Follow Pressure Relief Procedure found within the RS Gun and Cutter, Operation-Repair manual. 2. Engage trigger lock. 3. Remove cover (627). See page 20. Number of Strands US Metric One Strand Two Strands Three Strands 50-75 psi 80-125 psi 80-125 psi 3.

Maintenance Replace Anvil 7. Remove anvil (AC). 8. Install new anvil onto sleeve. 9. Install anvil cap. 10. Install cover and knob. AH AK AC AG AD AA AP NOTICE More tension between the anvil and blades leads to the anvil and blades wearing out faster. To prevent premature wear and to maximize anvil and blade life, use the minimum tension required to cut the glass and make small increases in tension when strands are not cut correctly. 11. Adjust Anvil to Cutter Head Tension, page 8.
Maintenance Replace Blades 10. Adjust Anvil to Cutter Head Tension, page 8. If glass is not getting cut properly, verify the tension is correct before replacing the blades. 1. Follow Pressure Relief Procedure found within the RS Gun and Cutter, Operation-Repair manual. 2. Engage trigger lock. 3. Remove cover (627). See page 20. FIG. 6 Blades are sharp. Always wear protective gloves to prevent cuts when the cutter cover is removed. 4.
