Structure and Features
Structure:
The Sprayer is composed of a spray tank , a
back cover , a battery , a diaphragm pump , spraying
parts
（
rubber hose , switch , spray boom and
spraying nozzle
）
, a strap , a trailer , etc.
Features
：
①
The spray tank is designed to be concise and
elegant , capable of mating with the trailer ,
easy to disassemble and assemble.
②
Come with a high-pressure and large flow pump
to work with nozzles of various functions and
an easy pressure-regulation unit to vary the
atomization pressure between 2-4.5 bar ,so as
to satisfy the demands of various operation
types and various nozzles, and attain the
purpose of cost-saving and high efficiency.
③
Come with a micro
diaphragm pump of compact size,
light weight, high pressure , even atomization, good
penetrability
，
high adhesion ratio, extended service life
as well as a reliable overload protection.
④
Come with a high-precision voltmeter and
low-battery alarm circuit for precise and
clear indication of
battery voltage . The alarm
will give warning when the battery voltage falls
below 10.8-10.5V, so as to prevent against
lower-power working or power-free storage of
battery, and keep the battery pole plate from
getting degraded, contributing to the
extended service life of battery.
⑤
Come with a dedicated charger of three-stage charging
type
（
constant current/constant voltage/maintaining
）
with short circuit/over current/reverse connection
protection. The indicator lamp

Designed to be human-friendly to allow for being
carried on back or on a trailer. When being carried on a
trailer, the height of handle bar can be varied
depending on the human height for easy operation.
