2.7 Driven
The machine has been subjected to a risk assessment. The dangers identi-
fied were eliminated as far as possible and identified risks were reduced.
Nevertheless, the machine poses residual risks, which are described in the
following section.
It is essential to observe the warning and safety instructions listed here and
in the action chapters of this manual in order to avoid possible damage to
health and dangerous situations.
2.7.1 moving parts
warning
Driven moving assemblies or parts can cause severe injuries!
−Do not allow people to remain in the danger area or in the immediate
vicinity.
−Do not remove covers such as flaps or maintenance covers.
−Do not disable, disable or bypass any safety device and/or function.
−Never reach into the running machine.
−Before starting work, always wait for the cutting disc to come to a
standstill and for residual energy to dissipate automatically.
2.7.2 thermal hazard
Caution
Risk of burns from hot surfaces!
Contact with hot components can cause burns.
−For all work on hot components, e.g. B. the engine, wear protective
clothing and protective gloves.

safety devices
20/ 65 Floor saw FS-500 B
2.7.4 Risks from noise
warning
Hearing damage from noise!
The noise occurring in the work area can lead to severe hearing dam-
age and even deafness.
−Always wear hearing protection during all work.
−Stay in the danger area only as far as necessary.
2.7.5 Risks due to safety devices that have been taken out of service
warning
Danger to life due to defective or bypassed safety devices!
Inoperative, bypassed or disabled safety devices do not protect against
the hazards and can lead to serious injury or death.
−Before starting work, always check that all safety devices are correctly
installed and functional.
−Never disable safety devices.
−Ensure that the safety devices are always freely accessible.
2.7.6 Make sure you have a tidy workplace
A messy workplace can lead to accidents. Unauthorized persons (children)
may not enter the workplace or operate the machine. After completing work,
secure the machine against unauthorized use. Be sure to catch or support
any part cut out during cutting (especially when cutting floors or ceilings).
Secure the device for unauthorized persons after the work has been
completed and secure it against unauthorized use.
2.7.7 Observe the entire environment of the workplace
Provide good lighting. Pay attention to the position of the cables, lines and
reinforcing iron. Never operate electrical tools near flammable materials.
2.7.8 Ensure a safe workplace
Keep the tools belonging to the device safe so that they cannot become
loose. Before switching on the device, check that all keys and other aids
have been removed. Ensure blade guards are securely fitted. Always keep a
safe distance from moving parts. Avoid abnormal posture and maintain a
stable balance.
2.8 safety devices
The operator of the machine is responsible for regularly checking the safety
devices and their functional safety.
