Maintenance
20. Inspect the water trap daily; drain water from the trap as needed.
21. Inspect pump piston shafts daily for material build-up and clean as needed.
22. Check inline filters weekly and clean as needed.
23. Check the hydraulic oil reservoir once a month to make sure the fluid level is correct.
24. Tighten recirculation and dispense gun packing to stop or prevent any leaks found.
25. Recirculate the materials occasionally if the unit is not going to be in use for several days.
Note
The material in the hoses can be recirculated using the ratio block.
Long-Term Shut Down
26. Place a container under each of the filter ball valves, then open each ball valve and allow
materials to drain out of each tank.
27. Set the Mode Selector switch to
RECIRC
and the Start/Stop switch to
START
.
28. Adjust the Rate Control so the pumps are moving slowly.
29. When the majority of the material is out of both tanks, close the filter ball valves, then set the
Start/Stop to
STOP
or adjust the Rate Control to zero.
30. Remove the lids from the feed containers and pour 1 to 2 liters of solvent into them.
31. Clean the container walls using a brush.
32. With the Mode Selector switch on
RECIRC
, turn the Start/Stop switch to
START
and
allow the pumps to recirculate the solvent through the recirculation gun and hoses for several
minutes.
33. Turn the Start/Stop switch to
STOP
or adjust the Rate Control to zero to stop recirculation.
34. With no mixer on the gun, turn the Start/Stop selector switch to
START
to purge the
materials into a waste container through the front of the gun.
35. Once both materials have been purged from the hoses and solvent is being dispensed out of
the gun, move to a second container to collect the dirty solvent.
36. Repeat steps through with clean solvent in each of the two containers until it comes out of
the gun clean, then run the pump until the solvent flow stops.
37. When the fluid sections are at the bottom of the stroke, turn the Start/Stop switch to
STOP
.
38. Inspect the throat seal oil level and add as needed.
39. Open the filter ball valve and allow the tanks to drain.
40. Remove the hex fitting from the top of the filters.
41. Remove the filter screens from housing, inspect for debris, and clean.
42. Allow solvent to dry before reassembling the filters.
