1.3 Verify that the filterand the tankdrain plug are securedbefore filling it.
1.4 Whenpreparing the mix,add water tohalf the tank;addthe chemical, andfill with
water.
2.- IGNITION
2.1 Liftthe choke leverandpump the primer locatednext to the fueltank a few times,
untilthefuel returntransparent hoseis filledup.
2.2 movethe accelerationlever upwards approximately onethird.
2.3 Pullthestartercorduntilthe motorturns on.
2.4 Openthe chokeslowly depending onthe motortemperature.

work.
2.7 Ifthe motor doesnot turn on easily, takeoffthe sparkplug anddo the following:
a) Ensurethe sparkplugproduces sparks whenstarting.
b) Whenthere is toomuchgasoline flow, the sparkplugdampens. Dry it.
NOTE: Alwaysconsultthe instructionsmanual.

3.- SPRAYING
3.1Elect thedesiredpressure turning the ribbed knobclockwise(high) or
counterclockwise(low), deppending onthework to beperformed. Remember that to
applyherbicides, the pressure mustbelow.For fungicides, insecticides,andfoliaters,
higherpressure can beused.
