mineral spirits.

base material, flush with mineral spirits, followed by
soapy water, then a clean water flush.

the equipment, at the end of the day, before storing,
and before repairing equipment.
Flushing

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.

empty metal pail to fill the pump and hoses.

under the pump.
To reduce the risk of static sparking, fire or explosion
which can result in serious bodily injury and property
damage. Always ground the sprayer and system com-
ponents and the object being sprayed.
• Ensure proper electrical service and amperage
and that the outlet is properly grounded.
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.
• To reduce risk of injection, always remove the
spray tip before flushing to avoid.
