2.4 Reasonably foreseeable misuse
2.5 General safety instructions
The operation of the gearbox involves residual risks even when adhering to the intended use.
Rotating components can cause serious injuries:

Before startup, remove objects, loose components (e.g. feather keys), and tools from the
gearbox, in order to avoid danger from thrown parts.

Keep a sufficient distance to moving machine components when the gearbox is running.

Secure the higher-level machine against restarting and unintentional movements during
assembly and maintenance work (e.g. uncontrolled lowering of lifting axes).
A hot gearbox can cause serious burns:

Touch the hot gearbox only with protective gloves.
The noise emissions can lead to hearing damage. The continuous noise pressure level may vary
according to product type and gearbox size:

Information about the operating noise L
PA
of your gearbox is available in Chapter 10.6
"Technical specifications", in the customized performance data (X093–D...) or from our
Customer Service / Sales department.

For noise protection measures, observe the total noise pressure level of the machine.
Loose or overloaded screw connections can cause damage to the gearbox:

Always use a calibrated torque wrench to tighten and check all screw connections for which a
tightening torque has been specified.
Solvents and lubricants are flammable, can cause skin irritation, and can pollute soil and water:

In case of fire: Do not spray with water to extinguish.

Suitable extinguishing agents are powder, foam, water mist and carbon dioxide. Observe
the safety instructions of the lubricant manufacturer (see Chapter 3.7 "Information about
the lubricant").

Use protective gloves to avoid direct skin contact with solvents and lubricants.

Use and dispose of cleaning solvents and lubricants properly.
A damaged gearbox can cause accidents and injury:

Immediately shut down a gearbox that has been overloaded due to misuse or a machine
crash (see Chapter 2.4 "Reasonably foreseeable misuse").

Replace the damaged gearbox, even if no external damage is visible.
Explosions can cause serious injuries and even death:

Ensure that the gearbox is only used in those areas for which it is approved according to the
name plate (see Chapter 3.2 "Name plate").

Be certain that there is no explosive atmosphere and that no dust enters the adapter plate
during assembly and maintenance.
Any use that deviates from the approved technical data (e.g. speed, force, torque,
temperature, service life) is not use as intended and is therefore not permitted (also
see Chapter 3.5 "Dimensions and performance data").
Table "Tbl-1" lists a summary of the possible hazards, their causes and protective
measures for potentially explosive atmospheres.
