MAINTENANCE AND ENVIROMENTAL PROTECTION
......................................................
1. Technical maintenance on spraying assembly:
- After spraying, clean out any residual spray mixture or dust in the chemical tank. Wash the tank and all
other parts.
- After dusting or granules spreading, clean the dust gate and chemical tank inside and outside.
- After operation, loosen the chemical tank lid. (4) After cleaning, the machine runs at low speed for 2—3
minutes
2. Maintenance on fuel system:
- The fuel mix with dust or water is one of main cause of the engine trouble, so the fuel system should be
cleaned very often.
- If the residual fuel remains in the fuel tank and carburetor for a long time, the residual fuel would be
glued and the fuel circuit clogged, thus causing the engine not to working properly. So as the machine
works for one week. All of the fuel should be discharged.
3. Maintenance on air filter and sparking plug:
- After the operation each day, wash the filter, if the chemicals adhere to sponge, it would deduce the
engine power, please pay attention especially.
- After wash the sponge with petrol, squeeze the petrol then fix the sponge in.
- The suitable clearance of sparking plug is 0.6—0.7mm, please check the clearance often, if it is too big or
too small, adjust it properly.
- The sparking plug model of this machine is 4106J. Do not use other model. If it is necessary for change,
you may buy it form local agricultural machinery department or plant protection department.
4. Deposit for along time:
- Clean the outside of the machine. Coat the anti-rust oil to the surface of metal.
- Take down the sparking plug. Feed 15—20g mobile oil into cylinder, the mobile oil should be specially
used for two-stroke petrol engine. Raise the piston to upper terminal point, then fix sparking plug.
- Screw out the two wing screws. Take off the machine tank. Clean the dust gate and the surface inside and
outside of chemical tank. If the residual chemical remains in the dust gate, the dust gate will not properly
and the leakage of dust will occur seriously. Then fit the chemical tank on and the loosen the tank lid.
- Take off the spray unit and wash it and then store additionally.
