Parts Replacement Procedure

Before performing maintenance on the dispense gun, follow Pressure Relief Procedure.

Notice

Due to the different o-ring materials and lubricants used in the dispense guns, never submerge or soak any dis- pense gun in any type of solvent. Submerging or soak- ing any dispense gun will immediately void the gun war- ranty.

1.Read each procedure entirely before beginning and refer to the illustration views as needed.

2.Flush and clean all passages as they become accessible.

3. Clean all parts before assembly.

4.Replace all O-Rings, Valves and Seals with new parts from the appropriate kit.

5.Inspect all parts for wear or damage and replace as required with new GENUINE GlasCraft REPLACEMENT PARTS from your authorized GlasCraft Distributor.

6.Inspect all threads for wear or damage and replace as required.

7.Tighten all threaded parts securely, but not excessively, upon assembly.

8.O-rings can fail if subjected to any of the following conditions.

a.Swelling - coming in contact with solvent or oil from compressor.

b.Cut - sharp, unlubricated edge in gun head or handle.

c.Sticky - contaminated with oil, water, solvent, catalyst, resin or gel-coat.

d.Chaffing - dry sliding surfaces (needs lubrication).

9.Lightly lubricate all O-Rings with petroleum jelly.

10.Check all springs for resilience. They should return quickly to their original (new) length.

11.Clean the exterior of the Gun and Hoses with an appropriate, clean solvent and cloth or brush.
