CLEANUP PROCEDURE
1 Perform pressure relief procedure.
2 Place pickup tube in a bucket of ushing uid. (Use water for water base
paint and pump conditioner for oil base paint).
3 Turn the power on. Close priming valve.
4 Increase pressure to half. Hold the gun against the paint pail.
Take off the trigger safety. Trigger the gun until ushing uid appears.
5 Move the gun to a waste pail. While holding the gun against the pail, trigger
the gun to thoroughly ush the system. Release the trigger and put the
trigger safety on.
6 Open the priming valve and allow the ushing uid to circulate for 15 seconds
(to clean the drain tube).
7 Raise the pickup tube out of the ushing uid and run the sprayer
for 20-30 seconds to drain the uid.
8 Close the priming valve. Trigger the gun into ushing pail to purge the hose.
9 Turn the power off.
10 Open the priming valve.
11 Unplug the sprayer.
12 Remove the lters from the pump and gun. Clean and replace.
13 If ushing was with water, ush again with pump conditioner to prevent
corrosion inside the pump. (For long term storage, mix motor oil
into the spirits).
14 Clean the exterior of the sprayer with rag soaked in pump conditioner.
DAILY MAINTENANCE
1 Keep the displacement pump packing nut/wet cup lubricated with
QLube Piston Lubricant at all times. Add a drop of oil with regular use to the
top of the pump. This helps protect the rod and the packings.
2 Inspect the packing nut daily. If seepage of paint into the packing nut and/or
movement of the piston upward is found (while not spraying), the packing
nut should be tightened enough to stop leakage only, but not any tighter.
Over tightening will damage the packings and reduce the packing life.

PACKINGS
The packings are a wearing part. If the pump can no longer maintain pressure,
has difculty priming and paint seeps into the throat of the pump, and
tightening the packing nut no longer helps, then the packings will require
replacement. This is best entrusted to a qualied repair technician.
