6Assembly & Operation
ASSEMBLY
The following steps are given as a guide to assemble your SprayMaxx sprayer:
1. Check inside the tank for any foreign objects.
2. Remove the pressure gauge from parts bag and fit onto sprayer.
3. Fit lid on top of the tank.
OPERATION
The following steps are given as a guide to operate your SprayMaxx sprayer:
• When mounting the sprayer to a vehicle using the ratchet tie-down straps, check that the
spray tank is still secure after the first 15 minutes of operation and re-tighten as necessary.
• Partially fill the tank with clean water.
• Connect the battery clips to a 12V DC power supply (red to the positive terminal, black to
the negative terminal) ensuring sufficient current capability (amps) to suit the pump. The
pump’s maximum amperage requirement can be found on its name plate.
• In order to prime the system and enable the pump to reach full pressure, depress the hand
lance trigger to release any trapped air. The pump may automatically switch off when the
hand lance trigger is released.
• Pump cycling may occur with insufficient nozzle delivery. This continual switching on and off
will reduce the battery and motor life. Should this occur, adjust the setting of the nozzle tip
or the regulator until the cycling stops.

7
Set Up
1. Securely fix the two hose wrap brackets to the SprayMaxx tank with the fittings provided.
2. Connect the SprayMaxx wire harness using the bullet connectors at the pump and then
connect to your 12 volt power source/battery.
3. If you would like to mount an optional boom, you can connect it by the 'boom port' on the
side of the pump.
4. Fill the SprayMaxx tank with water.
5. Before running the pump make sure the regulator is fully open to avoid premature wear or
damage to the pump. Squeeze the hand gun trigger to start discharge and then adjust the
pressure to your desired setting while keeping the gun trigger engaged.
NOTE: To maximize the pump's life, maintain pressure settings that do not cause the pump to
pulsate whenever possible.

8Calibration
1. Measure Nozzle Spacing: Measure the distance
between each nozzle to determine the length of
your travel distance.
2. Measure Distance to Travel: Mark the distance with two flags or between fence posts.
A tape measure capable of measuring further than 60m (200 ft), will make this easier.
3. Drive Measured Distance: Driving the sprayer at the intended spraying speed, time how
long it takes to travel between the marked distance. Repeat this procedure a number of
times and average the measurements. ie average time across the number of runs.
Nozzle Spacing = Distance to Travel
40cm (16”) = 78m (255’)
45cm (18”) = 70m (227’)
50cm (20") = 62m (204’)
55cm (22") = 56m (185’)
60cm (24") = 52m (170’)

4. Set Correct Spraying Pressure: With the sprayer
parked and the pump running, set the ideal or
intended pressure. REFER TO CHEMICAL SUPPLIER
5. Catch Output From Each Nozzle: Catch the fluid
output in a container (marked in oz) for the
same number of seconds it took to drive the measured
distance in step 3 (42 seconds).
Calculate the ‘average nozzle output’ by adding the individual
outputs and then dividing by the number of nozzles tested.
6. Analyse Results: The amount of liquid captured per nozzle equals the gallons per acre
application rate. (example: 16 gallons per acre).
7. Clean Nozzles: If the output of any nozzle deviates from the manufacturers’
guidelines by more than 10%, the nozzle should be replaced or cleaned. A toothbrush
works perfectly for this task.
8. Compare Recommended Rate: If the 1 gallon per acre rate is not within 5%
of the intended rate, you will have to adjust the pressure you spray at or the speed you
travel. You will have to repeat steps 3 - 7.
Calibration
Nozzle 1 16.5 oz
Nozzle 2 16.3 oz
Nozzle 3 15.9 oz
Nozzle 4 15.3 oz
Total = 64.0 oz
64 ounces divided by 4 nozzles =
16 gallons per acre.
At this point only can the figure be
converted to metric equivalent
eg. 72.3 litres
NOTE: This is only a basic guide on how to set up the
calibration for your sprayer, there are many factors to
consider when doing this process, we recommend you
research the best calibration for the sprayer, the application
and choice of chemical to be used before each use.
ALWAYS REFER TO THE CHEMICAL
MANUFACTURERS' TECHNICAL INFORMATION

Nozzle 1

10 Mixing & Filling
• Read the product label and follow the instructions carefully, taking special note with regard
to the order in which the products are added to the tank.
• Calibrate your sprayer according to the calibration method on page 9 using water only.
Calibration must be done with the nozzle tip that has been selected for the spraying task.
• Measure out the correct quantity of pesticides using clean measuring jugs used only for this
purpose.
• Half fill the SprayMaxx with clean water, then add the measured pesticide/chemical.
• Rinse out the measuring jug and empty the container. Pour all rinsings into the spray tank.
Agitate by stirring with a suitable round edged paddle.
• Top up the tank with water to the required level, ensure that the tank is not over-filled and
the outside is clean and dry before handling.
• Safely dispose of empty containers in compliance with current regulations.
• Mixing sites must be well away from watercourses and other environmentally sensitive
areas. Children and animals must be kept away.

11
Spraying
Planning to Spray Safely
• Before commencing spraying, plan the work effectively to reduce potential contamination.
• Wind direction and speed must be taken into account. Avoid spraying on still, hot and sunny
days or when wind speed exceeds 6.5km/h.
• Do not spray if the operator, bystanders, watercourses or any non-target vegetation appears
to be in danger from spray drift contamination.
• Drift can be reduced by lower nozzle height, lower pressures or by fitting larger nozzles.
Setting Up Your Spray & Adjusting the Regulator
• Prior to commencing spraying, you will need to adjust the regulator knob (blue) to suit the
desired pressure and spraying style.
• Winding the regulator clockwise will increase spraying pressure. Winding it anti-clockwise
will return liquid to the tank, increasing mixing and reducing spraying pressure.
• To begin, turn on the pump and activate the trigger or boom valve. Adjust the regulator to
achieve the desired pressure on the gauge. Turn off the hand lance/boom valve and check
to ensure the pump is not turning rapidly on and off or cycling. If the pump is cycling, you
will need to reduce the spraying pressure slightly until this stops.
NOTE: To operate the hand spray lance on-demand (where the pump activates only when the
trigger is pulled), wind the regulator clockwise completely until it stops. No water can return to
the tank and the pump pressure switch will control the pump operation.
When Spraying
• Spray at a constant speed (as used during calibration) and shut off the hand lance trigger at
the end of each swath or before changing direction.
• Work in parallel lines at the correct spacing when spraying a large area – this is better than
moving the hand lance from side to side in a swinging movement which causes damage by
overdosing.

12 Cleaning
• Drain Tank and Rinse: Rinse all liquid out of the tank. When flushing the sprayer, pay
attention to where the chemical will run. Always clean in an area that will not contaminate
water supplies, streams or crops.
• Pressure Wash Inside Tank: After draining the tank, rinse the inside by spraying clean
water with a pressure washer.
• Add Clean Water: It’s now time to shut the pump off and fill the tank with clean water.
• Flush Clean Water Through System: Turn the pump on and spray the clean water through
the boom and hand lance.
• Add Cleaning Solution and Water: Add the recommended cleaning solution to the tank
of water. To mix, run the agitator inside the sprayer. Operate for 5-10 minutes to mix the
cleaning solution with the water.
• Let Sprayer Sit For 8 Hours: With the water and cleaning solution left in the sprayer tank,
let it sit for about eight hours. This will allow the solution to remove any herbicide from the
residues inside the tank.
• Clean Nozzles, Screens, and Filters: It’s now time to rinse all nozzles, screens and filters.
To clean thoroughly, put them in a bucket of cleaning agent and water.
• Rinse Entire System with Water: When all nozzles, etc. are back in place, give the entire
system a complete rinse to ensure all cleaning solution is flushed through the unit.

13
Maintenance & Storage
MAINTENANCE
• After use, the SprayMaxx must be thoroughly decontaminated including the tank, pump,
hoses and the hand lance to avoid damage to crops from harmful spray residue and to the
sprayer from corrosion or blockage.
• After spraying, flush the tank, hose and the hand lance by running it with clean water plus a
recommended cleaning fluid. It is best to clean sprayers in the field or area just treated.
• The suction strainer attached to the pump suction line should be cleaned periodically.
Unscrew lid, remove filter and flush with clean running water.
• Nozzle filters (if fitted), nozzle tips, nozzle caps and gaskets should be cleaned by soaking
in water, brushing with a nozzle brush and allowed to dry. Never blow through the nozzles
with your mouth, nor use wire or pins to clear any blockages.
• When storing your spot sprayer ensure that it is clean and dry and kept in a well
ventilated place.
STORAGE
• Drain Tank: Fill the tank with clean water, start the pump and open all spray ends. If you
have a spray gun or boom, make sure you spray until clean water is coming through.
• Blow out Plumbing Lines: Using compressed air, blow out the hose lines to remove all
water from the system.
• Flush with Anti-freeze: Pour a small amount of anti-freeze into the tank and run the pump
until there is no more coloured liquid coming through the spray ends.
• Store Sprayer Inside: Turn off the sprayer ends so the remaining anti-freeze does not leak
out. If you have a boom attachment that hangs lower than the sprayer, we suggest you set
the sprayer on a few pallets.
