Power Cartridge Replacement
NOTE: The power cartridge consists of the alternator
(37), power supply (18) and retaining ring (35). See
Fig. 18.
1. Prepare the gun for service as instructed on page
22.
2. Remove the barrel as instructed on page 24.
CAUTION
Be careful when handling the power cartridge to
avoid damaging it.
3. Grasp the power cartridge with your hand. With a
gentle side to side motion, pull it free from the gun
handle (7). Then pull the power cartridge straight
out of the handle.
CAUTION
To avoid a loss in electrostatic performance, 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 (18b, 37a) on the new
power cartridge with petroleum jelly. All the o-rings
and the compression spring (18c) must be in place or
the gun will malfunction.
4. Insert the new power cartridge in the gun handle.
Be sure the gasket (18a) is in place.
5. Install the barrel on the handle as instructed on
page 28.
6. Test the gun resistance as instructed on page 19.
