CUP INSULATOR AND O-RING MAINTENANCE
CAUTION: Power-off the coolant pump before disassembling liquid-cooled barrels.
1. Unscrew Retaining Nut and slide back on barrel.
2. Using a firm pull and twist action, the Liquid-Cooled Gas Cup can be removed from the Cup
Insulator.
3. Inspect the Cup Insulator and o-rings (included with Insulator) for wear and proper lubrication.
It is considered good practice to replace all o-rings at the same time.
4. To remove the Cup Insulator, it must be UNSCREWED and pulled from the barrel. Use a rag
or towel (due to o-ring lubrication) and wrap it around the Cup Insulator.
UNSCREW and pull when completly unthreaded from barrel. Be sure the Insulator is fully
unscrewed from the threads. Pulling the Insulator over barrel threads will damage the
threads on the Insulator.
Inspect o-rings on barrel for wear and lubrication. It is considered good practice to replace all
o-rings at the same time.
5. To install the Cup Insulator, it must be pushed all the way onto the barrel then screwed onto
the threads. If necessary, place small amount of o-ring lubricant on the inside diameter of the
Cup Insulator, this will help it slide onto the barrel.
Push the Insulator onto the barrel until it bottoms out, screw onto barrel threads.
The Insulator MUST be all the way onto the barrel to assure proper coolant passage and from
blocking the gas outlet orifices.
6. Push Liquid-Cooled Gas Cup onto Cup Insulator. Slide Retaining Nut forward and tighten.
