VALVE ASSEMBLY (DRAWING PAGE 1.2). USED ON AIR RIFLE MODELS 100-101-102-104
FUNCTION: TO RECEIVE, STORE AND EXPELL AIR.
MALFUNCTIONS:
FAILURE TO HOLD COMPRESSION:
If your rifle fails to hold compression for normal shooting, test as follows: Cock the Hammer, pumping four strokes of compressed air into Chamber, close Breech
Bolt and insert muzzle end in container of water. If a steady stream of bubbles appear on surface, the Exhaust Valve is not functioning properly.
If the Exhaust Valve is in good condition, test for Check Valve trouble as follows: Cock Hammer, pump four strokes of compressed air into Chamber, pull out Lever
so that end of Pump is above small suction hole on Pump Tube. Wait a few seconds to permit air between Chamber and Pump to escape, then apply moistened
finger to suction hole and if a stream of bubbles appear, the Check Valve is not functioning properly.
