BEFORE OPERATING YOUR SPRAYER

Protecting your sprayer

Many plant protection chemicals are very aggressive,
discolour paint, and can be extremely difficult to wash
off when dried on.
It is therefore recommended that a rust preventative
product be applied to all surfaces.
A protective polymer such as HARDI-COAT or a thin
layer of penetrating, water-repellent rust prevention oil
should be applied before putting the sprayer into serv-
ice. Many suitable products are available on the market,
which after application leave a protective oil film. This
assists in preserving the finish of the machine and aids
in future cleaning.
This treatment should be carried out every time the
protective film is washed off.

Roadworthiness

When driving on public roads and any other areas
where traffic laws apply, please ensure that the required
signs and lights are fitted and working.
WARNING! Maximum driving speed is the lesser
of:
20 km/h less than the posted speed limit; and
30 km/h; and
The tyre manufacturers maximum speed.

Disconnecting sprayer

Always clean the sprayer inside and outside before
disconnecting and parking it.
Before disconnecting from the tractor, make sure the
support leg is properly fitted.
WARNING! To prevent the sprayer from tipping
over, do not disconnect the sprayer from the
tractor with the boom unfolded, unless the boom is
supported.
Place stop wedges in front of and behind the wheels.
Remember to disconnect all hoses and cables from the
tractor.
WARNING! If the sprayer is parked unattended,
avoid unauthorised persons, children and animals
having access to the sprayer.
