Purging and Priming the Sprayer
All new units are performance-tested at the factory and are shipped with test uid in the uid secon to prevent corrosion during shipment and storage. If you
have already used your pump, some water or solvent used in cleaning may remain in the uid secon. Whether your sprayer is new or if you have already used
it, this uid must be purged and thoroughly cleaned out of the system prior to use. Follow the steps below.
1. Place a full container of spraying material under-
neath the sucon tube (a). Secure the return tube (b)
into a waste container.
2. Turn the pressure control dial to maximum pressure.
Turn the PRIME/SPRAY knob to PRIME.
3. Plug in the sprayer and move the ON/OFF switch to
the ON (l) posion.

pump, or unl spray material is coming from the re-
turn tube.

so may lead to a stac electric discharge which may cause a re.
