To avoid injury from splashing fluid, never open a
cam-lock hose or applicator fitting while there is
pressure in the fluid line. Follow the Pressure Relief
Procedure on page 14.
Open the drain/purge valve (C) to relieve pressure if
pump or hose pack-out occurs, or to relieve pressure
inside the hose. Close valve when spraying.

Grounding
83A7829A
Grounding
The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape wire for the electric
current.
Ground the sprayer by plugging it into an outlet that is
properly installed and grounded in accordance with all
local codes and regulations. Do not modify the power
cord provided; if it does not fit the outlet, have the proper
outlet installed by a qualified electrician.
Extension Cords
• Use only a 3-wire extension cord that has a
grounding plug and a grounding receptacle that
accepts the plug on the product.
• Make sure your extension cord is not damaged. If
an extension cord is necessary, use 12 AWG (2.5
mm2) minimum to carry the current that the product
draws.
• An undersized cord results in a drop in line voltage
and loss of power and overheating.
NOTE: Certain GFCI outlets have been known to trip
while using this product. GFCI outlets have a range of
sensitivities. Motor controllers can cause false trips of
GFCI outlets. If you experience issues while using this
product, switch to a different GFCI model.

Operation
10 3A7829A
Flush
Failure to flush prior to material curing in the system will
result in damage to system and may require
replacement of all system parts in contact with the
material.
If the fluid/drain purge valve has been used to relieve
pressure, the valve must be flushed to prevent material
hardening in fluid/drain purge valve. If that is not
sufficient, remove, disassemble, and clean the valve
then reinstall.
• Flush if the materials in the system are about to
reach their cure time.
• Flush any time the flow rate starts to decrease as
this is a sign that material is starting to thicken and
cure.
• Always flush the system at least twice, draining all
water between flushes then replacing with clean
water.
• Flush using water only.
