6.6 Inspection / Maintenance of the Zero-Thrust Gun
In order to minimize potential problems with the Zero-Thrust Gun it is
recommended that the gun be treated at the end of each work period:
1. Flush and rinse the gun with fresh water after each use in sea water.
2. Place the gun in a container of clean, fresh water if it will be used in the next
24 hours. Ensure the gun is completely submerged.
3. If the gun will not be used for a period of several days, remove the super
swivel from the gun handle and, with the gun turned upside-down, pour
approx. 5ml of lubricating oil into the water inlet while opening and closing the
trigger. This will allow oil to reach the positioning pin and valve cone and
minimize the possibility of corrosion or mineral crystals forming that would
freeze the pin or valve cone.
4. Do not use WD-40 for long term storage.
