8.0 MAINTENANCE
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 trouble-free working life, it is important that each sprayhead
should be periodically checked, cleaned and lubricated.
8.1 Routine 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 build-up of dried
chemical degrades the droplet spectrum from an atomiser and may cause
vibration that can severely damage the unit.
8.2 Dismantling of Sprayhead
Should a sprayhead require maintenance, it must be dismantled and serviced as described
below. Numbers in brackets between 1 – 42 refer to parts of the sprayhead as shown in
the parts diagram on page 25.
IMPORTANT: Any defective parts must be replaced with genuine Micron spares.
Use of substitute parts or attempts at local repairs will void all warranties.
