page 30.
2. Remove the barrel as instructed on page 39.
CAUTION
Be careful when handling the power supply to avoid
damaging it.
3. Grasp the power supply with your hand. With a
gentle side to side motion, loosen the power
supply from the gun handle (7), then pull it straight
out. See Fig. 27.
4. Inspect the power supply for any physical damage.
Check the electrical resistance as instructed in
Test Power Supply Resistance, page 29. If nec-
essary, replace the power supply.
5. Inspect the power supply cavity in the handle for
dirt or moisture. Clean out the cavity with a clean,
dry rag to avoid a loss in electrostatic perfor-
mance.

power supply with petroleum jelly.
CAUTION
All the o-rings (18b, 37a) and the compression spring
(18c) must be in place or the gun will malfunction.

power supply in the gun handle.
