Grounding
334567B 11
Grounding
This sprayer includes a ground wire with an
appropriate ground contact.
The plug must be plugged into an outlet that
is properly installed and grounded in
accordance with all local codes and
ordinances.
Do not modify the plug provided; if it does not
fit the outlet, have the proper outlet installed
by a qualified electrician.
Power Requirements
•110-120V units require 100-120 VAC,
50/60 Hz, 13A, 1 phase.
•230V units require 230 VAC, 50/60 HZ,
8A, 1 phase.
Extension Cords
Use an extension cord with an undamaged
ground contact. If an extension cord is
necessary, use a 3-wire, 12 AWG (2.5 mm2)
minimum.
NOTE: Smaller gauge or longer extension
cords may reduce sprayer performance.
Pails
Solvent and oil-based fluids: follow local
code. 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 and
electric shock. An electric or static spark
can cause fumes to ignite or explode. An
improper ground can cause electric shock.
A good ground provides an escape wire for
the electric current.

the same rate on both sides of motor. Check both brushes.
Every 1000 gallons (3785 liters)
Check sprayer stall.
With sprayer gun NOT triggered, sprayer motor should stall
and not restart until gun is triggered again.
If sprayer starts again with gun NOT triggered, inspect
pump for internal/external leaks and check prime valve for
leaks.
Every 1000 gallons (3785 liters)
Throat packing adjustment
When pump packing begins to leak after extended use,
tighten packing nut down until leakage stops or lessens.
This allows approximately 100 gallons of additional
operation before a repacking is required. Packing nut can
be tightened without O-ring removal.

damage or wear caused by faulty installation, misapplication, abrasion, corrosion, inadequate or
improper maintenance, negligence, accident, tampering, or substitution of non-Graco component parts.
Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of Graco
equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper
design, manufacture, installation, operation or maintenance of structures, accessories, equipment or

IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY
OF FITNESS FOR A PARTICULAR PURPOSE.
