ESS GPS-5 OWNER’S MANUAL
About the low-voltage system of the MaxCharge™ spray gun
For operator safety, the MaxCharge spray gun is powered by a low-
voltage power supply. The rechargeable 9-volt batteries are in the
handle of the GPS-5 spray gun. The electrostatic charge imparted to
the spray is not strong enough to harm people. Some people report
feeling a “tingle” or a slight stinging sensation when the spray from the
nozzle falls on their bare skin.

Some owners report that they sometimes get a static shock when
spraying in an enclosed area. ESS wants to emphasize that these static
shocks, although sometimes unpleasant, are not at all dangerous to
people. They are simply an unfortunate consequence of spraying with
an electrostatic sprayer in an enclosed area. When you spray charged
particles onto other objects, some of the charge gets on you, or else
an opposite charge may be drawn up from the ground, depending on
the circumstances.
Here are some things to do to minimize static discharges. First make
sure that the sprayer is properly grounded. Your sprayer has a short
chain attached to the bottom of its case. It is important that this chain
touch the oor during use. If the chain is broken or missing, replace it.
Try misting the oor of the greenhouse or room with plain water
before spraying.
Pay attention to the exact conditions in which the shocks happen.
You may nd that you can prevent them by keeping your nger on
the metal trigger of the sprayer, rather than just holding its plastic
body. If the shocks happen only when you subsequently touch a piece
of equipment, try touching a painted or plastic part of it before you
touch metal.
You could also try wearing a dierent type of shoe. Leather will con-
duct better than rubberized soles and may lessen the problem.
Avoid touching sensitive electronic equipment such as computers,
printers, or cell phones while spraying . A static discharge could dam-
age them.
