Grounding Instructions
(Flammable Flushing and Cleaning Materials)
The striper is equipped with a grounding wire and
clamp. The clamp must be connected to a true
earth ground when flushing with flammable
materials. See Important Grounding
Information , page 4.
A metal sign post can be used as a true earth
ground. Connect the grounding wire and clamp to
a metal post. A properly grounded electrical outlet
can also be used as a true earth ground. Use the
provided adapter.
Plug the adapter in to a grounded outlet. Connect
the grounding wire and clamp to the metal stud on
the adapter. If the ground wire is not long enough
to reach a grounded electrical outlet, use a 3-wire
grounded extension cord between the adapter
and outlet.
Fluid hoses: Use only electrically conductive
hoses with a maximum of 300 ft. (91 m) combined
hose length to ensure grounding continuity.
Spray gun: Grounded through connection to a
properly grounded fluid hose and pump.
Pails
Flammable and oil-based materials: follow
local codes and regulations. Use only
conductive metal pails, placed on a grounded
surface such as concrete.
Do not place pail on a non-conductive surface
such as paper or cardboard which interrupts
grounding continuity.
Always ground a metal pail: connect a ground
wire to the pail. Clamp one end to the pail and
the other end to a true earth ground such as a
water pipe.
To maintain ground continuity when sprayer
is flushed or pressure is relieved: hold metal
part of spray gun firmly to the side of a
grounded metal pail then trigger the gun.
The equipment must be grounded to reduce the
risk of static sparking. A static spark can cause
fumes to ignite or explode causing serious
injury. A good ground provides an escape wire
for the electric current.
