Prime and Flush Storage Fluid
Before beginning a new spraying project you need to
prime the sprayer and flush the storage fluid out of the
sprayer.
Oil- or Water-based Materials
• When changing from water-based material to oil
based material, flush with soapy water and then
mineral spirits.
• When changing from oil based material to water
base material, flush with mineral spirits, followed by
soapy water, then a clean water flush.
• When flushing with solvents, ground pail and gun.
• Flush before changing colors, before fluid can dry in
the equipment, at the end of the day, before storing,
and before repairing equipment.
Flushing
1. Make sure the gun trigger lock is engaged and there
is no spray tip in the gun. Refer to the separate
instruction manual provided with gun for safety fea-
tures and how to engage the trigger lock.
2. Pour enough clean, compatible solvent into a large,
empty metal pail to fill the pump and hoses.
3. Place the suction tube into the pail or place the pail
under the pump.
4. Turn Pressure Control Knob to low.
5. Open the prime/pressure relief valve to the open -
“Priming Position”. This will allow an easy start.
6. Turn the engine ON/OFF switch to ON.

NOTICE
The equipment was tested with lightweight oil,
which is left in the fluid passages to protect parts.
To avoid contaminating your fluid with oil, flush the
equipment with a compatible solvent before using
the equipment for the first time.
• To reduce the risk of static sparking, which can
cause fire or explosion, always hold a metal part of
the gun firmly against the metal pail when flushing.
This also reduces splashing.
• Always remove the spray tip before flushing.
