OPERATING THE SPRAYER

1. Turn the handle of the control valve, and set 
it to the position for HERBICIDE, INSECTICIDE or 
HIGH PRESSURE to match the pressure to the op-

2. Check spraying conditions and the status of 
the equipment, the shoulder the equipment 
and set throttle lever to the high-speed posi-
tion.
3. When the nozzle cock is opened chemicals 
will be atomized as they come out of the nozzle.

 IMPORTANT: When the pressure control 

valve handle is changed to INSECTICIDE or 
HERBICIDE, with the throttle being fully open 
at HIGH PRESSURE position of pressure control 
valve handle, the engine speed will become too 
high, corresponding to the extent of lowered 
pressure. Therefor, use the equipment with the 
throttle lever some what turned back from the 
fully opened condition, when the equipment is 
used at the position for INSECTICIDE or HERBI-
