Weekly Gun Maintenance
Weekly maintenance on the gun includes tightening the resin and the
catalyst packing nuts.
1. Turn the pump pressure down to zero. Open up the ball valve to
relieve the fluid pressure on the resin and to release the fluid
pressure on the catalyst we’ll pull the trigger on the gun.
2. To seat the packings, tighten both the catalyst and the resin
packing nuts and quickly trigger the gun 10 to 15 times in rapid
succession. Repeat the process. It is very important to trigger the
gun quickly.
Surge Chamber Maintenance
For weekly cleaning of the surge chamber and filter turn the pump
regulator pressure down to zero.
1. To relieve the fluid pressure in the resin system, open the ball
valve below the resin filter.
2. To bleed the charge in the accumulator, insert the small diameter
rod in the charging valve on the top of the resin accumulator and
bleed the charge off. Be sure to cover the rod with a rag.
3. To remove the resin filter, move the return hose out of our way.
Push the core out of the resin screen. Clean the screen and the
core and the inside of the bottle.
4. Unscrew the resin accumulator. Clean the accumulator and filter.
Clean the threads and white ball.
5. Inspect the oil ring and replace if cut or distorted.
6. Reinstall the core into the screen. Then reinstall the screen core
into the filter bottle. It’s very important that we use Venus white
grease on the aluminum threads before re-installing. Do not over
tighten.
7. Reinstall the resin return hose to the ball valve below the filter.
Twist until there is a snug fit. Inspect the “O” ring. Replace if
necessary.
8. Place white grease on the “O” ring and on the threads. The seat
area must be clean for the polyball to seat properly when charging
the resin accumulator. Inspect the oil ring for any splits or cuts.
Replace if necessary.
