Evenly applying pressure to theextension while you screw it onto the gun body will ease the insulatingtube into the high-voltage bore without kinking it.6. Hold the gun handle and gun extension (30) in their mated position,and then slide the trigger (25) over the trigger puller (12) to hold thehandle and extension together.7. Secure the gun extension onto the gun handle with the screwsremoved during disassembly.8. Install the washer (27) and nut (26) on the socket head setscrew (28).1. Adjust the trigger puller, using the following steps:a. See Figure 7-5. Rotate the trigger puller (5) until the end of the airvalve needle (2) aligns with the flange on the gun extension (4)side of the puller. This is the adjustment starting point (3).b. See Figure 7-2. Install the trigger (25) and secure it with the pivotscrews (11).c. To check the adjustment, pull the trigger and make sure that thetrigger depresses the air valve needle (22) before the triggerpuller (12) begins its movement. When correctly adjusted, thetrigger puller (12) allows atomizing or horn air to flow before theneedle (33) on the packing cartridge (32) pulls away from itsseat (34). This allows the fluid to flow into the fluid tip (2).d. If the adjustment is correct, go to step 2. If re-adjustment isnecessary, remove the pivot screws (11) and trigger (25), andthen repeat steps a−c.External Parts (contd)Final Assembly andAdjustments
