Maintenance

•Check and add TSL to B side pump wet-cup daily.

•Check ISO lube bottle for significant discoloration or crystallization daily. Replace with fresh TSL when needed.

•Ensure ISO (A) pump is down and in PARK position during every shutdown.

•Keep any ISO (A) fluid from being exposed to atmo- sphere to prevent crystallization.

•Remove inlet filter screen plug (V, Y) and clean screens if increased unbalanced pressures between A and B is noticed or as needed for fluids used. Also clean after flushing.

•Close gun fluid shutoff valves when not in use.

•If using a Fusion Air Purge gun, add grease with grease gun per manual.

•Clean gun filter screens and mix chamber ports reg- ularly, or when increased unbalanced pressures between A and B is noticed. See gun manual.
