Barrel Installation

1.Be sure the gaskets (23 & 40a) and spring (11) are in place. See Fig 20 . Replace if damaged.

2.Place the barrel (10) over the power supply (40) and onto the gun body (39). Make sure the fluid rod spring

(11)is seated properly.

3.Tighten the three socket head cap screws (15) oppositely and evenly with the ball end wrench (46). Tighten the cap screws to 18 in-lbs (2 N Sm) MAXI- MUM (about a half turn past snug). DO NOT over tighten.

CAUTION

To avoid damaging the gun, DO NOT over tighten the cap screws (15). Tighten the screws to 18 in- lbs (2 N Sm) MAXIMUM (about a half turn past snug), using the wrench (46) supplied only.

4.Install the fluid tube back into the fluid fitting (21).

5.Install the actuator arm (29) and jam nut (25), with the jam nut assembled flush to the end of the rod.

There should be about a 1/16 in. gap between the ac- tuator arm (29) and the nut on the fluid shaft. When the gun is triggered, the electrode needle should draw back 3 to 4 mm. If necessary , adjust the jam nuts to obtain these dimensions.

The jam nut must be tightened securely to prevent it from loosening during operation.

6.Test the gun resistance as instructed on page 16.
