Grounding
The sprayer must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static build
up or in the event of a short circuit.
1.
220–240 Vac models require a 10A circuit with a
grounding receptacle. 100 – 120V Vac models
require 15A with grounding receptacle.
2.
Do not alter ground prong or use adapter.
3.
12 AWG, 3 wires with grounding prong, 300 ft (90
m) extension cord may be used. Long lengths
reduce sprayer performance.

WHAT TO DO
When check is not OK refer to this column
Basic Fluid Pressure
Problems
1. Pressure control knob setting. Motor will not run
if at minimum setting (fully counterclockwise).
1. Slowly increase pressure setting to see if mo-
tor starts.
2. Spray tip or fluid filter may be clogged.
2. Relieve pressure and clear clog or clean fil-

Basic Mechanical
Problems
1. Pressure control knob setting.
1. Motor stops running when pressure setting is
reached.
2. Pump (13) for frozen or hardened paint.
2. Thaw sprayer if water or water-based paint
has frozen in sprayer. Place sprayer in warm
area to thaw. Do not start sprayer until
thawed completely. If paint hardened (dried)
in sprayer, replace pump packings. (

placement Pump Replacement,
page 22.)
2. Displacement pump connecting rod pin (9a).
Pin must be completely pushed into connecting
rod (9) and retaining spring (9b) must be firmly
in groove of pump pin. See Fig. 8.
2. Push pin into place and secure with spring re-
tainer.

21.
Basic Electrical Problems
1. Motor control board. Board shuts down and dis-
plays error code.
1. Motor Control Board Diagnostics, page 18.
2. Extension cord. Check extension cord continu-
ity with volt meter.
2. Replace extension cord.
3. Sprayer power supply cord (29). Inspect for
damage such as broken insulation or wires.
3. Replace power supply cord.
