WARNING:

• Do not direct the air blast towards bystanders since the air can blow small objects at speed.
• Your power tool produces toxic exhaust fumes as soon as the engine is running. These fumes may be colorless and odorless and contain unburned and contain unburned hydrocarbons and benzol. Never operate the power tool in enclosed or poorly ventilated locations.
• During operation, the muffler or catalytic muffler and surrounding cover may become extremely hot. Avoid contact during and immediately after operation. Always keep the exhaust area clear of flammable debris. Allow the engine and muffler to completely cool before performing any maintenance activity.
• After working, wash your hands and clean all of your clothing. You know that the remaining pesticide can stain what you touch.

Fuelling
Pay attention to the fire. Please keep the fuel tank far away from the flame or sparks. Don’t smoke near fuel. When the machinery is running, ban adding fuel
to the fuel tank.
Open the fuel cap carefully to allow any pressure build-up in the tank to release slowly and avoid fuel spillage.
Fuel your power tool only in well-ventilated areas. If you spill fuel, wipe the machine immediately-if fuel gets on your clothing, change immediately.

• Check for leakage. To reduce the risk of serious of fatal burn injuries, do not start or run the engine until leak is fixed.
• After fuelling, tighten down the screw-type fuel possible.
• Gasoline is an extremely flammable fuel.Keep clear of naked flames. Do not spill any fuel- do not smoke.
  Always shut off the engine before refueling. Do not fuel a hot engine-fuel may spill and cause a fire.

Anti-electrostatic installation
Electrostatic charging with sparking can occur when working with the dusting and spreading attachment. The risk is greatest in extremely dry weather conditions–when using powdered products,–which create a highly concentrated dust cloud. To reduce the risk of sparking, explosion or fire, make sure the antistatic system is completely and properly mounted to the machine. It consists of a conductive wire in the spray tube connected to a metal chain. The metal chain must make contact with a conductive surface to dissipate electrostatic charges. Do not operate your machine on a non-conductive surface (e.G. Plastic, asphalt). Never operate your machine with a missing or damaged discharge system
For the above reasons, great care is required when using sulphur as it is flammable.

• Assembly as fig.4.

Rotation Check

• Checking whether the spark plug and all the connections are tightened.
• Checking whether the cooling air channel is clogged. If so, the engine will be overheated.
• Checking whether the air filter is dirty. If so, the dirt will reduce the amount of air drawn in. So the engine does not run well and waste fuel.
• Check whether the gap of the sparking plug is 0.6˜0.7mm.
• Pull the starter 2 or 3 times, check whether it rotates normally.

Fuelling

• Use a special type 2-cycle oil (30ml of oil for each 1L of unleaded gasoline 95 octane). The ratio between them is determined by the oil instruction. Incorrect gasoline, oil and mixture may damage the engine.
• Never fuel the engine when it is hot or running.
• When fuel, never take away the strainer.

Adding chemicals

• During the spraying operation, while adding chemicals, the switch must be shut, see Fig.5. During the dusting operation, the dusting valve throttle and fuel lever should be on the bottom position, otherwise, the machine will have chemicals out.
• As powder chemicals can easily become blocked,so the chemicals should not be in the chemical tank for a long time.c. While spraying, the chemical tank lid should be turned on tightly. After adding powder chemicals, please clean the screw of the chemical tank mouth, then turn on the lid tightly.

Cold starting
Please operate according to the following procedures:

• Press the oil cup until the gasoline into oil cup, see Fig.6.
• Put the switch on the starting position, see Fig.8.
• Put the choker on the full position, see Fig.7.
• Pull the starter for a few times and have it returned slowly. Do not leave the handle to return freely to avoid damage of the starter.
• Close the choker and pull the starter handle until the engine ires.
• After starting the engine, open the choker fully.
• Let the engine run at low speed for 2-3 minutes, then start the spraying or dusting operation.

Starting the warm engine

• Leave the choker fully open.
• If the engine draws in too much fuel. Leave the fuel switch fully close,pull the starter 5-6 times. Then start the engine as above.

Stopping the engine

• Put the two control handles to their lowest positions and the engine stops.
• Spray over, turn off the chemical switch first then stop the machine.
• Having finished working, turn off the fuel switch. Pay attention!
  Note: While the engine is running, the hose must be mounted to the machine, otherwise cooling air will be reduced and this can damage the engine.

Misting
Loosen the pressing lid,regulate the length of the nozzle opening to meet the different requirements of misting. Turn the regulating valve to change the amount of misting, See Fig.9.

Dusting
Regulate the discharge by shifting the dust rod’s position in the three holes of the rock-arm, see Fig.10.   Stating the engine

• Put the dust gate handle to the lowest position before starting the engine, otherwise, chemicals will be jetted when starting engine.
• It is prohibited to stand in front of nozzle. Even though dust gate is closed, residual dust in pipe will be blown out.

Safety warnings (Misting/Dusting)

•  It is in to carry out operations during cool weather with little wind. For example, in the early morning or in the late afternoon, this can reduce the evaporation and drift of chemicals and improve the protecting effect.
• The operator should move windward.
• Review area to be cleared. Look for potential hazards such as stones or metal objects. Spectators and fellow workers must be warned, and children and animals prevented from coming nearer than 15m while the blower is in use. Do not point the blowy pipe at people or animals.
•  If your mouth or eyes are spattered with chemicals, wash them with clean water and then go to see the doctor.
• If the operator has a headache or dizziness, stop working at once and go to see a doctor in time.
• For the operator’s safety, misting/dusting must be carried out strictly according to the instruction of the chemicals and agricultural requirements.
