Key points

• Never assume that a new sprayer is ready to spray when it is first delivered.

• Make sure the sprayer is free of residues and debris before operating the spray system.

• Always do a thorough check of all systems and inputs to the rate controller when the sprayer arrives.

• Ensure the sprayer is fully calibrated before its first spraying job.

• Plan to include checks as a part of your spraying process: some of these can be done while you are spraying, others should be done at the end of every load, or at the end of every job.

• Undertake a thorough annual check of the sprayer.
