Suction Filter
It is essential to maintain all filters, and filter
screens, in good condition. Filter screens that
are not regularly cleaned can severely impede
the flow and thus affect delivery pressure.
If the screen is in any way damaged, it can
allow foreign material into the pumping
system which can result in damage to the
pump, lines, valves and nozzle tips. If the
screen is not properly fitted, it can allow air
into the pumping lines which will reduce the
performance of the pump. The filter screen
should be cleaned after every spraying
operation. The best way to clean the filter
screen is with a soft brush or compressed air
after washing the entire chemical residue from
the pump.
SAFETY SHUT-OFF VALVE
The safety shut off valve enables the filter bowl
to be removed while automatically shutting off
the supply line to the filter. As the filter bowl
is removed together with the bowl cap, the
valve plunger seats so as to seal off the filter
from the supply line. Replacing the filter bowl
unseats the valve plunger and thus opens the
supply line to the filter.
SUCTION FILTER CLEANING
WARNING:
Appropriate PPE must be worn
when cleaning filters.
1.
Ensure the pump is turned off.
2.
Carefully unscrew filter nut and remove
bowl and avoid contact with residual
chemical.
3. Remove screen and clean (with a soft
brush or compressed air).
4. Check for damage to screen, bowl,body
and O-ring.
5. Place screen back in position.
6. Make sure O-ring is in position for proper
seal.
7. Replace bowl and screw nut on. Do not
over-tighten nut.
Filling
When filling the sprayer it is necessary to use
an external water source.
WARNING
: Operators must wear the
appropriate PPE.
The following steps should be followed when
filling the tank:
1. With sprayer mounted on the vehicle, park
on level ground.
2.
The pump should be turned off.
3. Remove the tank lid.
4. Add 20% of the tanks volume of clean
water, or more, if the chemical is in a
denser form e.g. powder.
5. Add chemical as required. Some agitation
will take place as the rest of the water is
added.
6.
Use external water source to fill main tank
(Do not exceed the tank capacity).
7. Replace the tank lid and ensure that it is
secure prior to switching on pump. You are
now ready to use the sprayer.
WARNING
: When filling tank with water, 1
litre of water will add 1 kg of weight. Some
chemicals have a higher density than water
and will weigh more per litre. Therefore, it
is the operators responsibility to ensure the
loaded weight of the sprayer does not exceed
the towing and / or carrying capacity of the
vehicle.
