Graco Inc 312579H Clean Nozzle and Air Cap, Compliant Cleaning Methods

Daily Gun Maintenance

Clean Nozzle and Air Cap

1.Remove air cap (13), trigger gun, remove nozzle (11), and soak both in a compatible cleaning solution.

CAUTION

Trigger the gun whenever you tighten or remove the nozzle. This keeps the needle tip away from the nozzle seating surface and prevents the tip from being damaged.

2.Clean air cap, nozzle, and front of the gun with a soft-bristle brush dipped into com- patible solvent. Do not use a wire brush or metal tools.

3.Use a soft implement, such as a toothpick, to clean out air cap holes.

4.Trigger the gun while you install the fluid nozzle with the gun tool. Tighten the nozzle securely to 155-165 in-lb (17.5-18.6 N•m) to obtain a good seal.

5.Install the retaining ring (14) and air cap (13).

When reassembling, make sure the

air cap matches the color etched onto the side of the nozzle (gold, brown, grey, blue, etc.).

6.After cleaning the gun, lubricate the follow- ing parts with lubricant 111265 daily:

•fluid control valve threads

•trigger pivot pin

•fluid needle shaft

Compliant Cleaning Methods
