Spraying Guide
The following steps are given as a guide for spraying with your trailer unit.
• Before commencing spraying, plan the work effectively to reduce potential
contamination to a minimum.
• Wind Direction and speed must be taken into account. Avoid spraying on hot
and sunny days or when wind speed exceeds 6.5km/h
• Do not spray if the operator, bystanders, watercourses or any not targeted
vegetation appears to be in danger from spray drift contamination.
• Drift can be reduced by lower nozzle height, lower pressures or by fitting larger
nozzles.
• To commence spraying, squeeze trigger. Release the trigger to stop the spray –
the regulator will automatically allow spray solution to bypass through the return
line and back to the tank.
• Spray at a constant speed (as used during calibration) and shut off the hand
lance trigger or boom at the end of each swath or before changing direction.
• Work in parallel lines at the correct spacing when spraying large area – this is
better than moving the hand lance from side to side in a swinging movement
which causes damage by overdosing.
