Use and Care Manual
Grounding
TO PREVENT ELECTRIC SHOCK AND
DEATH FROM INCORRECT
GROUNDING WIRE CONNECTION:
Check with a qualified electrician if you are
in doubt as to whether the outlet is properly grounded.
Do not modify the power cord plug provided with the
sprayer. Never remove the grounding prong from the
plug. Do not use the sprayer if the power cord or plug
is damaged. If damaged, have it repaired by a service
facility before use. If the plug will not fit the outlet,
have a proper outlet installed by a qualified electrician.
Grounded Sprayers:
Sprayers With Three Prong Plugs
3-Prong Plug and Outlet
1. Sprayers marked with “Grounding Required” have a
three wire cord and three prong grounding plug. The
plug must be connected to a properly grounded outlet.
If the sprayer should electrically malfunction or break
down, grounding provides a low resistance path to
carry electricity away from the user, reducing the risk
of electric shock.
2. The grounding prong in the plug is connected through
the green wire inside the cord to the grounding system
in the sprayer. The green wire in the cord must be
the only wire connected to the sprayer’s grounding
system and must never be attached to an electrically
“live” terminal.
3. The sprayer must be plugged into an appropriate
outlet, properly installed and grounded in accordance
with all codes and ordinances. The plug and
outlet should look like those in the preceding
illustration.
Extension Cords
1. Grounded sprayers require a three
wire extension cord. Double Insulated sprayers
can use either a two or three wire extension cord.
2. As the distance from the supply outlet increases, you
must use a heavier gauge extension cord. Using
extension cords with inadequately sized wire causes
a serious drop in voltage, resulting in loss of power
and possible sprayer damage.
3. The smaller the gauge number of the wire, the
greater the capacity of the cord. For example,
a 14 gauge cord can carry a higher current
than a 16 gauge cord.
4. When using more than one extension cord to make
up the total length, make sure each cord contains at
least the minimum wire size required.
5. If you are using one extension cord for more
than one sprayer, add the nameplate amperes
and use the sum to determine the required
minimum cord size.
6. If you are using an extension cord outdoors, make
sure it is marked with the suffix “W-A”
to indicate it is acceptable for outdoor use.
7. Make sure the extension cord is properly wired
and in good electrical condition. Always replace
a damaged extension cord or have it repaired
by a qualified electrician before using it.
8. Protect the extension cords from sharp objects,
excessive heat, and damp or wet areas.

NOTE: ALWAYS clean sprayer immediately to prevent permanent damage.
IMPORTANT ELECTRICAL INFORMATION
A
ttention
Use only a 3-wire extension cord that has a
3-blade grounding plug and a 3-slot receptacle
that will accept the plug on the product.
Make sure your extension cord is in good condition. When
using an extension cord, be sure to use one heavy enough to
carry the current your product will draw. An undersized cord
will cause a drop in line voltage resulting in loss of power and
overheating.
A 14 or 12 gauge cord is recommended (see chart). If an
extension cord is to be used outdoors, it must be marked with
“SJW” or “SJTW”. For example, a designation of SJTW would
indicate that the cord would be appropriate for outdoor use.
