SETUP AND TESTING
It is always recommended that you first test all spray equipment thoroughly with clean water. The TR25-S7 is
supplied with a Spray Gun containing a large orifice blue adjustable nozzle, which when twisting the tip can
allow for a greater flow of liquid. It is recommended that adjustable nozzle is used first and can be changed
later if you require. The TR25-P requires the operator to fit your specific purpose selected Spray Gun.
1.
Be sure to wear safety equipment as recommended by the chemical manufacturer before adding chemical
to the sprayer
2.
Check the filter is clean and undamaged (see Maintenance section).
3.
Fill the tank with clean water.
4.
Ensure the 6-meter spray hose and spray lance connected. (TR25-S7 Fit the blue adjustable nozzle or any
large orifice nozzle you may wish to use).
5.
Check all pipes, hoses, hose clamps and connections for leaks or damage.
6.
Switch the pump ON.
7.
Depress the spray lance trigger to flush air from the lines. The pump is self-priming and should start
spraying within 30 seconds.
8.
Check the hose connections for leaks, if any are found stop the pump and rectify the problem before
continuing.
9.
For the TR25-P Pressure can be controlled by turning the knob on the Pressure regulator; clockwise will
increase the pressure, anti-clockwise will decrease the pressure. The desired pressure can be fixed by
securing the locknut against the adjustment knob.
10.
For the TR25-P Its highly recommended that the selected output pressure and the orifice size of your
selected nozzle(s) allows the pump to run, so that the pump motor is not cycling on/off during operation
(also called pulsation).
11.
Once the nozzle is set and the pump operates free of pulsation/cycling, the spot sprayer is ready to be
utilized for spot spraying of chemical.
Important note: Spray units must not be operated while the pump is pulsating/cycling because it can
cause premature component failure.
Chemical solution may now be added to the tank.
Follow the mixing instructions and safety precautions provided by the chemical manufacturer. Before adding
concentrated chemicals, partially fill the tank with water then add the chemical and complete filling with
water.
Wear all the safety equipment recommended by the chemical manufacturer before adding chemical to the
sprayer and whilst conducting spraying operations.
The Spray Gun used with the Domestic unit (TR25-S7) has an additional safety feature; the lever catch can be
used to lock the lever closed to prevent accidental spraying. The catch can also be used to lock the lever open
for continuous spraying. This should only be done when safe to operate in this manner and where there is no
likelihood of inadvertently spraying any person or property that may suffer damage.
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 in the pump, spray lines and block the filter.
If heavy frosts are experienced, run the sprayer until the pump and spray lines are dry. This will prevent water
freezing in the pump or spray lines 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.
Operation
