Grounding
ti24584a
Grounding
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.
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
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.
•110-120V units require 100-120 VAC,
50/60 Hz, 13A, 1 phase.
•230V units require 230 VAC, 50/60 HZ,
7A, 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.
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.
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.

Check voltage supply to the sprayer
(control board is detecting a multiple
voltage surges).
Control is commanding motor to run
but motor shaft does not rotate.
Possibly locked rotor condition, an
open connection exists between
motor and control, there is a problem
with motor or control board, or motor
amp draw is excessive.
Turn ON/OFF switch OFF and
disconnect power to sprayer.
Locate a good voltage supply to
prevent damage to electronics.
1.Remove pump and try to run
sprayer. If motor runs, check for
locked or frozen pump or drive train.
If sprayer does not run, continue to
step 2.
2.Turn ON/OFF switch OFF and
disconnect power to sprayer.
3.Disconnect motor connector(s) from
control board socket(s). Check that
motor connector and control board
contacts are clean and secure. If
contacts are clean and secure,
continue to step 4.
4.Connect a DC voltmeter across the
two motor wires – red & black spin
the motor fan and check for a
voltage to register on the meter. If
voltage is not present, check
brushes. If OK, replace motor. If
voltage is present, go to step 5.
5.Perform a spin test by connecting a
9 –12 Volt battery to the motor
leads. Motor leads may vary in style
and size. Locate the two wires
going to the carbon brushes
normally Red and Black. Motor
should spin when battery is
connected to the motor leads.

Basic electrical problemsMotor leads are securely fastened
and properly mated
For loose motor brush lead
connections and terminals.
Brushes must be 1/2 in. [13mm]
minimum. NOTE: Brushes do not
wear at the same rate on both sides
of motor. Check both brushes.
Broken or misaligned motor brush
springs. Rolled portion of spring must
rest squarely on top of brush.
Motor brushes may be binding in
brush holders.
Motor armature commutator for burn
spots, gouges or extreme roughness.
Replace loose terminals; crimp to
leads. Be sure terminal are firmly
connected.
Heat from inductor coil of filter board may
destroy wire insulation that comes in
contact with it. Exposed wires could cause
shorts and component damage. Bundle
and tie loose wires so none lay in contact
with inductor coil on the filter board.
