5.4 Operating Hints
 While running, the engine produces toxic exhaust gas which is odourless and invisible. Never start or
operate the machine in closed rooms. Ensure for adequate ventilation in confined areas such as
ditches or dips.
 No other persons should be present within a circle of 15 meters from the operator.
 Keep persons and animals away from areas in which you are working. Never spray in the direction of
other persons, animals or objects that could be damaged as a result. Bear in mind that the liquid
emerges at high speed from the spray tube. Objects could be kicked up as a result, and this could in
some cases represent a risk. The user is responsible for any hazards or accidents involving other
persons and/or their property.
 Never operate on unstable ground. Watch out for any obstacles such as tree stumps, tree roots,
ditches, etc.
 Take special care while working along slopes.
 Never touch a hot exhaust.
5.5 Irregularities, incidents, accidents
 In case of irregularities, leaks, visible damage or reduced efficiency, do not commence work, but leave
the unit from a dealer check.
 When irregularity, leaks or malfunctions occur during operation, turn off the stop switch immediately
and put the machine on the ground immediately. The device may only be used again if it is checked by
a specialist workshop and the cause of the fault has been eradicated.
 In case of serious disturbances or accidents during operation of the unit as smoke, strong odors from
the device or the device is in flames instantly remove the unit from your body and take a safe distance.
In case of fire, you have to call the fire department immediately.
5.6 Safe handling of spraying agents
 Avoid contaminating the environment, the mains water supply and/or public sewer systems with
spraying agent or cleaner!
Ensure to avoid contamination when mixing, filling, using, draining, cleaning, servicing and transporting
by using adequate procedures and suitable containers.
 Spraying agents and cleaners must never be allowed to enter the mains water supply – not even by
back-suction when filling, public sewer systems, sprayed onto wastelands, allowed to drain into natural
bodies of water or disposed of together with normal domestic waste. This also means that appropriate
care must be taken during filling to ensure that none of the spraying agent is drawn back into water
pipes. Spraying agents and cleaners and any unused leftovers of spraying agents and cleaners must
always be collected in a suitable container and disposed of via approved facilities for household
chemical waste. Please contact your local authorities for information about your nearest disposal
facilities.
 Avoid any direct contact with spraying agents. In case of contact with harmful pesticides rinse the
affected body parts immediately with plenty of water, any clothing soaked with spraying agents should
be changed immediately, seek medical advice if needed.
 Stop working immediately if you start to feel unwell while working, or if you become unusually tired.
Seek medical advice if the condition persists.
 Never allow children or anybody who is not familiar with handling this type of spraying agent to handle
the spraying agent.
 Clean the spraying agent tank and all other spraying agent carrying parts whenever the spraying agent
is changed. To flush out any residue from the agent tank and the hose, run the device with clean water
after cleaning the spraying agent tank and before the next spraying agent is filled in. This will prevent
the risk of any chemical reactions taking place between the different substances.
 Never use the device in narrow or enclosed spaces – spraying agents are toxic and there is a risk of
poisoning. Spraying equipment must for example only be used in greenhouses if adequate ventilation
is provided. Signs must be put up in greenhouses that have been treated. Nobody should enter the
greenhouse again until it has been thoroughly ventilated.
 When you have finished working, prepare the device for storage according to section 13.5 / section
13.6, thoroughly wash your face and hands with soap, take off your work clothing and ensure that it is
washed regularly. Any unused spraying agent that is left over in the device could cause corrosion and
hence damage the device. Special attention must be paid to wearing parts like hoses, filters and seals.
