Using Electrical Cords
Grounding and Electrical Requirements
Sprayer must be grounded. Grounding reduces the risk
of static and electric shock by providing an escape wire
for electrical current due to static build up or in the
event of a short circuit.
This 120 Vac sprayer requires a 120 Vac, 60 Hz, 15A
circuit with a grounding receptacle.
Never use an outlet that is not grounded or an adapter.
Extension Cord Requirements
Only use an extension cord with an undamaged
3-prong plug for 120 V.
When operating sprayer outdoors, use an extension
cord suitable for outdoor use.
NOTE: When using an extension cord, always use a
cord coupler or an extension cord with locking plugs to
ensure that your sprayer maintains power during operation.
Your extension cord must have an adequate wire size
(AWG or American Wire Gauge) to be able to carry the
current that your sprayer draws. A smaller gauge number has a greater capacity than a large one. For example, 14 gauge wire has a greater capacity than 16 gauge
wire. An undersized extension cord will result in a drop
in line voltage and loss of power, overheating, and possible damage to equipment.
When using more than one extension cord, make sure
each individual cord contains at least the minimum wire
size needed. The table below shows the correct size to
use depending on extension cord size and gauge. If you
are unsure, it is better to use a heavier gauge than
needed. Remember, a smaller number indicates a
larger gauge wire.
Do not use the sprayer if the electrical cord has a damaged ground prong.
Power Cord
• Damaged or entangled cords increase the risk of
electric shock.
• Do not abuse the sprayer cord.
• Do NOT use the cord for carrying, pulling, or
unplugging the sprayer.
• Keep the cord away from heat, oil, sharp edges,
and moving parts.
• Do not operate the sprayer with a damaged cord.

Reversible Spray Tip
Always perform Pressure Relief Procedure before
adjusting spray tip position.
In the event that particles or debris clog the spray tip,
this sprayer is designed with a reversible spray tip that
can be used to quickly and easily clear the particles and
resume spraying as quickly as possible.
• Always point the reversible spray tip
forward when spraying.
• When particles or debris get caught in the spray tip,
it can be reversed to quickly clean the spray tip.
•See Unclogging Spray/Tip Guard Assembly
(page 14) for detailed instructions.
• Thin materials sprayed at high pressure settings
may cause the sprayer to enter an operational mode
designed to protect it from overheating. This mode
is noticeable by the sprayer sounding like it is slowing down and will result in a poor spray pattern.
To exit this mode, turn pressure control knob
down to lowest pressure setting that results in
an acceptable spray pattern.
• If spraying in low pressure range, there may not be
enough pressure to clear the plug. Turn pressure
control knob up to clear the plug.
NOTICE
See Choosing Pressure Control Knob Setting on
page 12 for recommendations on the setting for your
job.
Flexible Suction Tube
This sprayer comes with a flexible suction tube for
multi-directional spraying without adjustment.
To ensure proper function of flexible suction tube, orient
flexible suction tube screen end forward (away from trigger) as shown below and push firmly into place.
Pressure Control Knob
(Not available on all units)
NOTE: If the sprayer is angled or tilted too far, the
flexible suction tube will lose contact with the material
and the sprayer will stop spraying.
• To reduce overspray, always spray at lowest pressure that results in an acceptable spray pattern.
• Spray test pattern and adjust pressure to get
desired coverage.
• With some materials, if pressure is set too low, no
material may spray out. Turn pressure control knob
up.
