Graco PRO Xs4 AA manual Test Barrel Resistance

Test Barrel Resistance

1.Insert a conductive rod (B) into the gun barrel (removed for the power supply test) and against the metal contact (C) in the front of the barrel.

2.Measure the resistance between the conductive rod

(B) and the barrel contact ring (16a). See Fig. 7. The resistance should be 19-29 megohms. If the resis- tance is incorrect, make sure the metal contact (C) in the barrel and the barrel contact ring (16a) are clean and undamaged.

3.If the resistance is still outside the range, remove the barrel contact ring (16a) and measure the resistance between the conductive rod (B) and the wire lead at the bottom of the contact ring groove.

4.If the resistance is in range, replace the contact ring (16a) with a new one. Press the contact ring firmly into the groove on the front of the barrel.

WARNING

Fire, Explosion, and Electric Shock Hazard

The barrel contact ring (16a) is a conductive contact ring, not a sealing o-ring. To reduce the risk of sparking or electric shock, do not remove the barrel contact ring (16a) except to replace it and never operate the gun without the contact ring in place. Do not replace the contact ring with anything but a genuine Graco part.

Electrical Tests

5.If the resistance is still outside the range, replace the barrel.
