Service and Maintenance Intervals
General Info
National or regional laws may require periodic inspection of the sprayers in use. See the following section for more details.
The subsequent periodic service and maintenance work may be carried out by the user. Contact your HARDI dealer if in
doubt. If this work is completed correctly, the sprayer will run efficiently and its lifetime will be prolonged.
When a number of hours are mentioned in this chapter, this means hours of spraying, unless otherwise explained. Operation
hours can be read in the controller in the tractor (see instruction book for controller).
Periodic Inspection
According to EU Directive 2009/128/EC regarding sustainable use of pesticides, all countries in the European Union are
obliged to inspect sprayers used for plant protection. This mandatory inspection also includes your HARDI sprayer.
The condition of the sprayer must be verified. The object of the inspection is to ensure a safe and uniform distribution of
spray liquid on the plants, as well as minimizing leaks into the environment. The inspection on your sprayer may involve
testing the condition of the pump, PTO, tanks, liquid system, measuring components, spray boom, nozzles, agitation of spray
liquid, filters, pipes and hoses.
The inspection and testing is carried out by an authorized person, who is not the owner nor the operator of the sprayer. With
a positive result, a certificate or test sticker will then show that the inspected sprayer is approved for future use. With a
negative result, the faults must be rectified to get the approval.
Check your national rules and guidelines for requirements included in this inspection as well as the interval between
inspections. For more information on how to approach this inspection, please contact your local HARDI dealer.
Tightening Bolts and Nuts
When tightening bolts and nuts as a part of periodic service or due to replacement of spare parts, it is important to apply
the correct torque. This will prevent accidents and prolong the lifetime of the parts included in the bolted joints.
If not otherwise stated in this book, please tighten bolts and nuts using the following torques.
*Exceeding this value results in a great risk of deforming the bolt.
