Nozzle assembly
It is very important to follow all the maintenance
and cleaning procedures to ensure that the electro-
static sprayer will function properly. although the
MaxCharge™ nozzle will outperform all electrostatic
spray technology on the market, regular cleaning
will ensure peak operating performance.
The nozzle assembly is located at the end of the
spray gun wand. It is composed of a nozzle body,
internal o-ring, Teflon ring, cover, external o-ring,
and a hood (see labeled drawing at right). To access
the nozzle components, just unscrew the nozzle
cover by hand.
Cleaning the spray gun
always rinse the spray gun out with clean soapy
water after every day’s spraying. That is the most
important thing you can do to ensure trouble free
operation of your TrG-5 sprayer. by cleaning after
each and every working day you will avoid the long-
term chemical buildup that eventually causes clogs,
poor spray patterns and shortens nozzle life.
establish maintenance intervals to disassemble and
clean the nozzle. Your nozzle maintenance schedule
will vary depending on the types of chemicals used
and adherence to pre- and post-spray checks. In
general it is sufficient to thoroughly clean nozzles
every 50 hours. If heavy loads of wettable powers
are used, the cleaning schedule should be sooner.
To clean the nozzle assembly
1. slide the hood over the nozzle cover.
2. unscrew the cover from the nozzle base and remove the Teflon ring. Clean any debris from
around the nozzle tip.
Note: There is a small o-ring in the nozzle around the base of the tip, take care that it doesn’t fall
off. If it does, clean it and press back into place. also, take care not to damage the nozzle tip when
the cover is removed.
3. soak the ring, cover, and hood in a mild detergent solution. use a small brush (soft or mild
bristle) to clean the inside of the cover and the hole through it. also, be sure to clean the hood.
It is important to clean inside the hood and the two cavities. rinse thoroughly.
4. scrub the nozzle base with the detergent solution using a soft bristle brush. Clean the ceramic
outlet. be sure to thoroughly clean the base cavity and take care not to damage the nozzle tip.
rinse and make sure the small o-ring is in place.
5. reassemble nozzle by placing the Teflon ring on the base and screwing the cover on hand
tight. next, slide the hood over the nozzle and seat it securely against the external o-ring.
wipe clean the exterior of all hoses and fittings connected to the nozzle.
The electrode cover should be hand tight. Never use pliers or other tools to tighten it. The insulating
ring should be loose.
