The Turbofan Sprayhead is manufactured from high quality materials which have been selected for maximum strength, reliability and resistance to agricultural products. In order to ensure a long and
8.1Routine Maintenance Before each spray operation:
1.Check the general condition of the system, including hydraulic and chemical hoses and fittings; repair any leaks.
2.Check condition of the bearing and hydraulic motor of each sprayhead by rotating the atomiser by hand. Any roughness, stiffness or sideways movement indicates that the unit requires maintenance.
3.Check the condition of the atomiser and fan blades. These should not be damaged and must be free of any chemical contamination. Clean if necessary and replace any damaged parts.
4.Check that each atomiser is correctly positioned and that its chemical flow restrictor is correctly adjusted for the work being undertaken.
5.Check that the hydraulic system is adjusted to give the correct rotational speed for all sprayheads.
Each day after spraying:
1.Empty any remaining chemical from the spray system.
2.Flush the entire system through with clean water or a suitable solvent. This procedure is particularly important if chemicals containing solids in suspension have been used as powder can settle out in pipework and cause blockage.
3.It is recommended that the outside surfaces of all sprayheads and booms are washed down with a pressure washer or similar in order to prevent build up of spray chemicals.
4.Ensure that all atomiser discs are free of contamination. Any
