OPERATION AND CARE FOR LONG LIFE OF
MACHINE
1. Operation or spraying
• After spraying clear any residue or dust from
the solution tank. Wash the tank and all other parts.
• After aerial spraying or dispersing granules,
clear plate and sprayed inside and outside the tank.
• After work loose plate of the chemical tank.
• After cleaning the machine left the engine
running at minimum power for 2-3 minutes.
2. Operation of the fuel system
• Fuel mixed with water or dust is a major cause
of engine problems h, so the fuel system should be
cleaned frequently.
• If the remaining fuel stays in the tank and
carburetor long time, it can kleyasa and clog the
fuel system. This is the reason the engine does not
work well. Once the machine has not worked one
week all the fuel must be drained.
3. Operation of the air filter and spark plug
