SECTION 5
OPERATION
BOOM SPRAYING
Some customers will fit out their sprayers with a small boom,
such as Croplands MBX-04. For further information on
boom spraying, refer Section 6 - Spraying Information.
OPERATING POINTERS
While spraying continually observe that:
• Adequate operating pressure is being maintained.
• Your hand gun coverage is correct and constant for
effective cover.
• The nozzle is operating correctly.
• Periodically check and clean filters.
• Avoid going too slow because over application will
occur. Conversely, avoid going to fast because under
application will occur.
Tank Agitation
It’s important to use chemicals that remain in solution whilst in a
spray tank. The tank can only be agitated by the bypass side
of the Pressure Regulator unit. For this reason, it’s important to
make sure the pump is generating (slightly) more pressure than
required for spraying ... if the pump is not generating enough
pressure there will be no bypass/agitation.
12-VOLT PUMP DUTY CYCLE
12-volt pumps are not recommended for continuous duty
service due to limited motor brush life. To protect the pump
from excessive heat, the 12-volt pumps are fitted with a
thermal cut-out switch.
Once the maximum thermal limit is reached, the motor
must be allowed to settle to a lower (ideally ambient)
temperature, before resuming operation.
Running the pump at or near the maximum thermal limit for
an extended period of time will shorten the life of the pump
and may result in immediate pump failure. Operation at
lower pressures and temperatures, however, will extend
overall pump service life.
EMERGENCY
ACTION PLAN
Never operate the sprayer
without an action plan in place for
when things go wrong ...
“Take 5”
to evaluate the risks
Actions for most foreseeable
machine issues such as
breakages start with ...
“Drop the speed”
“Dump the pressure”
then evaluate further.
WARNING
!
It is recommended to keep the hose from
the sprayer on unsprayed ground and
uncontaminated from the spray.
This minimises contaminants on the hose
and minimises exposure to chemicals when
handling and rewinding the hose.
