Note The packing nut only needs to be tightened snug enough to put pressure on
the packing set assembly. Only adjust the packing nut when there is NO fluid
pressure load in the fluid section.

full with TSL oil.
36. Prime the fluid section with fluid.
37. Close the gun head.
38. Slowly increase the pump pressure to between 60 and 80 psi (4 – 5.5 bar).
Note If your unit has a priming button, you will need to press and hold it.
39. Keep the pump stalled for 5 to 15 minutes to allow the packing to set.
Note If the pump is slowly moving while it should be stalled, it indicates that there is
a leak past the ball or seals in the up stroke.
40. Repeat steps 36 - 39 for both the up and down strokes.
41. Decrease the pump pressure to the desired operating pressure.
42. Reconnect, prime, and pressurize the catalyst pump for operation.
Servicing Accumulator & Filter
1. Disassemble and clean the accumulator and filter approximately once each week.
Note This will need to be done more frequently if the weather is hot.
Note If you must keep increasing pressure to maintain an adequate spray fan, the
filter may be clogged with debris. If the spray is pulsing, the accumulator is
probably blocked.
