Using Electrical Cords
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.
Do not use the sprayer if the electrical cord has a damaged ground prong.
Extension Cord Requirements
Only use an extension cord with an undamaged
3-prong plug.
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.
Power Cord
Extension Cord Gauge
(AWG Minimum)
18 50 ft (15 m)
16 100 ft (30 m)
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.
