Service Work Precautions

Before carrying out any service work, all of the following instructions must be followed in order to prevent damages to the
sprayer, injuries and fatalities:
• do not walk under any part of the sprayer, unless it is secured. The spray boom is secured when placed in the transport
brackets
• if the spray boom is folded up and resting in the transport brackets for service, check visually that the paralift locks are
engaged (the boom is locked in place)
• if the spray boom is unfolded for service, the boom must be lowered, until it reaches its end stop. Place strong trestles
under the boom for support or use a lifting crane for support
• never service or repair any equipment while it is operating
• any service work is preferable carried out on level ground with only authorized persons nearby
• depressurize the hydraulic system for the sprayer to prevent unintentional movements of the sprayer
• switch off the PTO
• switch off the tractor and remove the ignition key to prevent unintentional starting
• activate the parking brake to prevent rolling
• put chocks in front of and behind the wheels to prevent rolling
• electric power must be disconnected from the sprayer

or other liquids.

Cleaning

When cleaning nozzles and filters, lower the spray boom to around waist height above the ground. For safety reasons, do
not walk or stand below the boom or paralift during this cleaning work!
Dispose of oils, greases and filters in the appropriate way to protect the environment.
Cleaning of tanks:
• Due to toxic vapours from spray liquids in the main tank, climbing into this tank is very hazardous. Cleaning should only
be done from the outside.
• Refrain from entering the main tank.
• Refrain from inspecting any of the tanks with the liquid pump running.
Rinse and wash equipment with clean water after use and before servicing.
