Operation

Starting the Pump

1.Open the bleed-type master air valve (A).

2.Trigger the gun into a grounded metal pail, holding a metal part of the gun firmly to the pail.

3.Slowly open the air regulator (E) until the pump starts running.

4.Run the pump slowly until all the air is purged, release the gun trigger, and lock the trigger safety - the pump will start and stop as the gun is opened and closed.

Adjusting the Pump

•Always use the lowest pressure necessary to get the desired results.

•Never allow the pump to run dry of fluid being pumped. A dry pump will quickly accelerate to a high speed, possibly damaging itself. If your pump accelerates quickly, or is running too fast, stop it immediately and check the fluid supply. If the supply container is empty and air has been pumped into lines, prime the pump and lines with fluid, or flush and leave filled with a compatible solvent. Be sure to eliminate all air from the fluid system.

•The piston and intake check valves of displacement pump 247599 are factory-set for light viscosity flu- ids. This setting minimizes surging at pump stroke changeover. To adjust the valves for heavier viscos- ity fluids, see manual 312745.

•Always stop the pump at the bottom of its stroke to prevent fluid from drying on the rod and damaging the throat packings. When you finish pumping, always relieve the pressure, page 9.

•If you are pumping fluid which dries, hardens, or sets up, flush the system with a compatible solvent as often as necessary to prevent a build up of dried fluid in the pump or hoses.

•Every 40 hours of operation, check that the packing nut is tight. Relieve the pressure, page 9. Then, tighten the packing nut just snug - do not overtighten or the packings may be damaged.
