Swivel Repair

4.Install the spring (22), male gland (24†) and five v-packings (23†) one at a time, make sure the lips of the v-packings face into the housing. Install the female gland (25†) and the swivel stud.

Needle Adjustment

WARNING

Proper adjustment of the needle is essential to be sure the trigger safety latch makes the gun inoperative when engaged. Improper adjustment may allow the gun to be triggered, even with the trigger safety latch engaged, resulting in serious injury, including fluid injection and splashing in the eyes or on the skin.

1.	Relieve the pressure. Disconnect the hose.
2.	With the trigger safety latch (29) engaged,
	squeeze the trigger. There should be about 0.125

3.To adjust, remove the tip guard or nozzle exten- sion. Release the safety latch. Squeeze the trigger and loosen the locknut (4). Insert the wrench (3) into the tip of the needle (10) and turn it in or out until the proper free play is obtained. Tighten the locknut (4).

4.Install the tip guard. Start the system. Trigger the gun and release; fluid flow should stop immediate- ly. Now engage the trigger safety latch. Try to trigger the gun; no fluid should flow. If the gun fails either test, relieve the pressure and re- adjust the needle.
