Grounding Procedure for Gas Engine
The equipment must be grounded to
reduce the risk of static sparking. Static
sparking can cause fumes to ignite or
explode. Grounding provides an escape
wire for the electric current.
To ground sprayer: Attach sprayer
grounding clamp to earth ground.
Air and fluid hoses: Use only electrically
conductive hoses with a maximum of 500ft.
(150 m) combined hose length to ensure
grounding continuity. Check electrical
resistance of hoses. If total resistance to
ground exceeds 29 megaohms, replace hose
immediately.
Spray gun: Ground through connection to a
properly grounded fluid hose and pump.
Grounding Procedure for Electric Motor
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.
If using the electric motor, plug must be
plugged into an actual 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, 15A, 1 phase.
• 230V units require 230 VAC, 50/60 Hz,
16A, 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.
12 334558C
Pressure Relief Procedure
ti25360a
Grounding of Pails
Solvent pails used when flushing: Follow
local code. Use only conductive metal pails,
placed on a grounded surface. Do not place
the 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.
Pressure Relief Procedure
Follow the Pressure Relief
Procedure whenever you see this
symbol.
This equipment stays pressurized until
pressure is manually relieved. To help
prevent serious injury from pressurized
fluid, such as skin injection, splashing fluid
and moving parts, follow the Pressure
Relief Procedure when you stop spraying
and before cleaning, checking, or
servicing the equipment.
1. Engage trigger lock.
2. Turn gas engine or electric motor
