5.3.3 Important notes when spraying:
A) Swing the spraying tube with your hand after
turning on the handle valve. In order to avoid
chemical harm, it is strictly prohibited to spray
only in one place.
B) Operator should face the wind. The spraying
tube should form an approximate 15° angle.
C) During spraying, the spraying tube should be
swung continuously between the left and the right
to increase spraying range.
5.3.4 Pressure regulation. When the engine’s speed
is 5000-6000rpm, regulate the water pressure of
the plunger pump.
If it is necessary to regulate, please do this
procedure as per the instructions on Figure 5.
Figure 5
5.3.4 Spraying. Regulate the fuel handle to allow the
machine to run at about 6500r/min and turn on the
handle spraying valve to begin spraying.
5.3.5 Stopping. Move the stop switch to the STOP
position when the engine idles.

5.4 Avoid fire.
a) NEVER start a fire or smoke near the machine.
b) NEVER refuel the machine when it is hot or running.
c) NEVER pour fuel on the machine. If you do, clean it
immediately. After adding fuel, screw down the fuel tank
lid, then move the machine to a new place to start the engine.
5.5 Spraying operation.
a) Chemical spraying should be performed under cool weather with little wind. We recommend
spraying early in the morning or in the late afternoon. This will reduce evaporation and drift of
chemicals improving spray efficiency.
b) The operator must walk facing the wind.
c) If chemical touches the operator’s mouth or eyes, wash them immediately with clean water and
and then visit a doctor.
d) If the operator has a headache or feeling dizzy, he must stop working immediately and should
visit a doctor.
e) For the operator’s safety, spraying must be carried out strictly according to the instruction
of the chemicals being used.
