Check the pump switch is in the off position. Plug the battery charger into a standard 240 Volt powerpoint. Connect the
coaxial plug on the output lead to the socket on the sprayer.

connection, blown fuse)
FILLING THE TANK AND ADDING CHEMICAL
Warning : Before using the sprayer for the first time or adding chemical check the operation and function of the
sprayer with clean water
Check that the battery is charged, the filters are clean and all fittings, hoses and gun connections are tight.
Partly fill the sprayer before adding chemical. Always use clean water to prevent blockages and ensure chemical function is
not inhibited.
Add the chemical according to the directions on the chemical container following all safety and protective equipment
recommendations.
Do not use wet powders or chemicals that must remain suspended in solution and require agitation. Only use chemicals or
dyes that fully dissolve.
Do not use a sprayer that has been used to spray herbicides for insecticides or nutrients unless the sprayer has been
thoroughly cleaned including neutralizing the herbicide according to the manufactured directions if required.
OPERATING THE PUMP
The pump has an off switch located on the base (bottom) of the
sprayer. The pump will also switch off automatically when the spray
lance is not in use, however when the tank is empty this does not
function. When leaving the sprayer unattended always switch the pump
switch off.
SWITCH POSITION 0 = OFF, 1 = ON
OPERATING THE SPRAYLANCE
Depress the trigger to operate the lance. The nozzle on the end of the lance can be
adjusted by twisting to create a solid stream or a hollow cone shape for misting. For
herbicide sprays do not use a fine mist as the mist can easily be carried off target by the
wind and kill or damage other plants.

Maintenance
To avoid chemical contamination wear appropriate protective equipment including gloves whenever maintenance is carried
out; turn off the pump and depress the trigger on the spray lance to dissipate any pressure.
After spraying is completed, drain unused chemicals from the tank. Rinse the tank with clean water then operate the sprayer
with clean water in the tank to clean out the pump, hose and spray lance. Do not leave chemicals in the tank as they may
crystallize or form solids and block in pump, spray lines, nozzle or filters.
If heavy frosts are experienced, run the sprayer until the pump and spray lines are dry. This will prevent water freezing in
the pump and damaging the sprayer.
Warning ! Dispose of unused chemical and water used for rinsing in a manner that will not endanger people, animals or
the environment in accordance with local regulations and the handling and disposal information available from
the Chemical manufacturer.
CLEANING THE FILTERS
The knapsack has 3 filters that require cleaning. Always use clean water and rinse out the sprayer after use to avoid filters
becoming clogged.
1. Basket strainer under lid. Clean when dirty.
2. Filter in gun handle. Unscrew the hose connection to the gun and withdraw the filter using a pair of pointy nose
pliers and clean.
3. Suction filter inside tank. Unscrew the filter using a pair of pliers grasping it on the hexagonal brass section against
the tank. Withdraw the filter, disassemble and clean. When reassembling do not over tighten

Maintenance
USING THE VACUUM PUMP
If the sprayer has not been used for some time or has been left with chemical in it then the pump valves may become
stuck. If this happens the pump will run but no liquid is pumped.
If this happens you can use the hand operated vacuum pump to prime the pump as follows:
1.
2.
3.
Empty the tank and spray hose of liquid
Make sure the power switch on the knapsack is off
Connect the hand pump as shown in the pictures below and lock the trigger on
Lock Trigger On
4.
5.
Pump the handle to draw some air and un stick the pump valves
Clean the vacuum pump after use.

TROUBLE SHOOTING GUIDE
Remedy
 Ensure battery wires are connected to battery properly.
 Check the inline Fuse in the power loom
(Fuse is Blown or cable to fuse is loose/ disconnected).
 Check battery is not flat or charger has not been working.
Connect Charger to 240V Power socket, Charger Indicator light
should be Green when not connected to sprayer
Battery charger is not charging or
battery related issues.
Pump operates but cycles or
continues to run when the wand
handle is released
Pump operates with no flow rate or
reduced flow
 Connect to charge socket on sprayer. Charge indicator light will
change from GREEN to RED when charging.
 If Light remains GREEN when connected Battery is charged. Turn on
pump Light should change RED to indicate charging (no problem)
 If Light remains GREEN when pump on connection in Battery Box is
loose. Check all terminals are fitted and fuse not blown. If fuse OK
rattle fuse connector to check it part is loose.
 There is a slow leak of liquid. Check all connections.
 The tank is empty or the suction line is not fully immersed.
 The pump will not prime unless the gun trigger is on.
 Check filter, nozzles and spray lines for blockage.
 Pump valves may be stuck or blocked. Use the hand air vacuum pump
according to the instructions in manual. Alternatively apply a small
amount of pressure to the suction line by placing a garden hose over the
suction hose inside the tank while the pump is running.
