3. Operating Steps:
 Charge the battery before first use. The battery charger plugs
into the side of the sprayer.
 Connect the spray rod to the handle, and put in an O-ring to
assure a tight seal. The wand length can be adjusted
according to the actual need. Connect the nozzle to the nozzle
rod joint and tighten it to prevent leakage.
 Open the tank cap, slowly pour the liquid into the tank through
the filter. Do not take the filter out when pouring. This
electrostatic sprayer can contain 8 liters (2.2 gallons) of liquid.
Do not overfill. Put the cap on to the tank and tighten it, tilt
slightly, there should be no leakage outside the tank cap.
 Check sprayer for leaks. If leaks are detected, check and
tighten connections.
 There are two switches on the main unit. The red switch turns
on the main power to the pump. The green switch turns on the
electrostatic feature. The green light will not illuminate until the
power switch on the handle is also turned on.
 Avoid accidental starting. Be sure power is in the OFF
position before inserting battery pack.
 BE SURE THE POWER SWITCH ON THE HANDLE IS OFF
BEFORE TURNING ON THE POWER (RED SWITCH) AT
THE TANK.
 HOLD THE HANDLE WITH YOUR RIGHT HAND WITH
GOOD CONTACT WITH THE GROUNDING ELECTRODE
ON THE HANDLE
 DO NOT TOUCH THE NOZZLE OR WAND WITH YOUR
LEFT HAND OR BODY WHILE THE ELECTROSTATIC
FEATURE IS BEING USED

 After turning on the main power switch, turn on the handle
control switch to start normal operation. If you want to pause
the spray while using, just turn off the handle control switch
and then spray again just by turning on the handle control
switch.
 When shutting down, turn off the handle control switch, the
main power switch and the electrostatic switch on the tank..
4. Spray Method:
 The unit comes with two nozzles to provide different spray
volume and size particles.
 When spraying, place the spray head at a height of 30-50 cm
above the objects, Move the wand horizontally back and forth
and walk at a pace to achieve the desired coverage. Adjust the
pace according to the objects and spray effect desired.
 The selection of operating parameters is related to the liquid
type, concentration of liquid solution and working environment
of different objects being sprayed. It should be determined by
knowledgeable personnel and tested if necessary.
 Use this machine as a mist-type electrostatic spray. When the
atomization effect is good, just spray it on the top of the object.
Do not spray the liquid to the level of forming large droplets or
dripping. The diameter of the droplet is about 30 to 80um
depending on the nozzle selected.
 High humidity may affect the electrostatic adsorption effect.

5. Drip Guard
 After turning off the power, a small amount of liquid that was
under pressure in the wand may drip from the nozzle. For
certain applications with frequent on/off use a drip guard is
provided.
 Install and use the provided drip guard to collect drips.
 Loosen the connection at the end of either wand and pull the
wand extension completely out of the wand body.
 Slide the drip guard over the wand extension until it is flush
against the nozzle. See below
 Tighten the connection and use normally.
 Empty as needed while spraying

6. Maintenance and Cleaning:
 After each operation, the remaining liquid should be drained.
Do not use cleaning liquid which can corrode plastic and metal.
To clean the sprayer use soap, water and a damp cloth to wipe
clean. To clean internal components run water through the
sprayer for 3 minutes.
 If the sprayer will not be used for an extended period wash it
with a cleaning solution and store it after drying.
 Do not immerse parts such as the tank base and handle in
water and also prevent water from immersing these parts as
the sprayer may be damaged or the effect will be impacted.
 When the spray operation is not used, the spray wand and
nozzle should be hung on the tank hook to prevent leaking and
to ensure the safety of the person and equipment.
 When handling liquids, the safety instructions provided by the
liquid manufacturer should be observed to ensure safe use.
 It is not advisable to use powder based solutions and other
special working fluids to avoid clogging the filter screen,
nozzle, damage to the sprayer and personal injury.
 The charger plug should be removed after charging and not be
connected while spraying.
 The sprayer should not be used for long-term storage and
should be charged once a month.
