2.Remove the gasket (46) from the gun. See Fig 17.

CAUTION

The power cartridge is fragile. Be careful when handling it to avoid damage.

3.Grasp the power cartridge with your hand. With a gentle side to side motion, pull it free from the gun handle (2). Then pull the power cartridge straight out of the handle.

CAUTION

DO NOT use solvents to clean the power cartridge cavity in the gun handle (2). Solvent will damage electrical components contained in the power cartridge.

Inspect the power cartridge cavity in the handle for dirt or moisture. Clean out the cavity with a clean, dry rag if necessary.

Lightly lubricate the o±rings (3b, 5a, 5b) on the new power cartridge with petroleum jelly. All the o± rings and the compression spring (5c) must be in place or the gun will malfunction.

If it ever is removed, push the cushion, adhesive side in toward the barrel, with a rod until it is securely adhered in the barrel. DO NOT use the power supply (5) to press the cushion into the barrel as it will not ad- here properly.
