Safety instructions for adjustment, maintenance, and inspection work (s)
•The operator must ensure that all maintenance, inspection, and installation work is
carried out by authorized and qualified professional personnel who, after carefully
reading the instruction manual, have sufficient knowledge
•Maintenance, inspection, and assembly work must only be carried out when
hydraulics is disconnected.
•For maintenance work under the tool carrier, secure with appropriate support
elements.
•When replacing attachment tools, check the hydraulic system for residual pressure
- any remaining residual pressure is reduced to zero (0 bar).
•Use only suitable maintenance and adjustment tools and wear safety work gloves,
safety shoes and safety goggles.
•Handle the hydraulic oil and grease in compliance with regulations. Be familiarized
with the safety data sheets.
•Immediately after the completion of work, all safety devices must be installed and
reactivated.

17
Scorpion 4, 6 and 8
Safety instructions for the operator / user
•It is important to familiarize yourself with all equipment, the elements of service
and their function before starting up work. If your work has started, it is too late.
•The user's clothing must be tight-fitting. Avoid loosely fitted clothes.
•Check the area before start-up (children / obstacles, for example stones, fences,
steel wire). Ensure adequate visibility and properly lighted conditions. The safety
distance specified in the tool's instruction manual must be followed unconditionally.
•The user must be fully rested before using the machine - and take a break if
he/she feels tired, to ensure the safety of him/herself and others.
•The user should ensure variation in working positions and take frequent breaks to
avoid musculoskeletal disorders.
•It is not permitted to be on - to 'ride along' or in any other way - the tool or machine
during transportation and work.
•When operating, never leave the driver's seat.
•When operating under high voltage lines, extra distance and caution is required.
High voltage lines
Always be aware of overhead lines. Between
power pylons there will always be a risk of touching the
overhead lines.
In case of doubt - contact the local power plant for instructions on
safety distances.

18
Scorpion 4, 6 and 8
Working in public places
When working in public places, such as roadsides, careful consideration should be
shown to others in the area. Stop the machine immediately when, for example,
pedestrians, cyclists, and riders pass by. Do not resume work until the passer-by is
again at safe distance.
Warning signs in public places
The work area should be marked with appropriate signs as this is legal
requirement in public places. Signage must be clearly and correctly
placed so that the danger is clearly visible.
Contact the Road Directorate for detailed information on current
regulations. The Road Authority must be advised before commencing
work on public roads.
- Time and place must be announced.
Suggested signage on public roads
•Warning Sign: "Road work" with additional, specifying sign, for example "Verge
cutting". "0-1 km" or appropriate shorter distance.
•Warning Sign: “Road chicane” with the additional "One lane only“.
•Command sign: "Hold left" White and blue arrow sign on the back of the machine (*).
* This applies within the EU where traffic passes left of the machine
working in the traffic direction. The indications, use, and colours of arrow signs depend
on the laws and regulations of each country.
Further use of warning signs
•On two-way roads, signs are placed in both directions.
•The work should be within 1 km. of signage.
•Only perform work when visibility is good and when the risk is small - for example
outside rush hour.
•The vehicle must be equipped with a flashing light bar.
•Vehicles should be in eye-catching colour.
•Material residue should be removed from the road and sidewalk as quickly as
