2.5 Reasonably predictable misuse
2.6 Guarantee and liability
Guarantee and liability claims are excluded for personal injury and material damage in case of
- Ignoring the information on transport and storage
- Improper use (misuse)
- Improper or neglected maintenance and repair
- Improper assembly / disassembly or improper operation
- Operation of the gearhead when safety devices and equipment are defective
- Operation of the gearhead without lubricant
- Operation of a heavily soiled gearhead
- Operating the gearhead despite leakage or unusual running noises
2.7 General safety instructions
The gearhead is specified for installment on motors that:
- correspond to the design B5 (for any divergences, please consult our Customer
Service Department [technical customer service])
- show a radial and axial runout tolerance of at least “N” according to DIN 42955
- have a smooth shaft
- feature at least the same temperature class as the gearhead.

We recommend temperature class T3 and higher, because the gearhead may
not be permitted to heat up to more than 90 °C in normal conditions. The
gearhead can be heated additionally through heat connection to the motor, and
thus reach a higher housing temperature than 90 °C. The performance of our
gearhead in explosion-risk areas would therefore no longer be guaranteed.
Any use transgressing the maximum permitted speeds, torques and temperature
(especially ignoring the regulations on explosion protection) is not compliant with the
regulations, and thus prohibited.
- Operating the gearhead in an atmosphere whose ignition temperature lies under
the temperature class specified on the type plate.
- Modifications or reconstructions that have been executed without written approval
of
WITTENSTEIN alpha GmbH
Operating the gearhead in areas for which it is not approved can lead
to explosions that can cause serious injuries and even death.

Make sure that the gearhead is only used in those areas for which it is
permitted according to the identification plate (see Chapter 3.1 "Type
plate").
Assembly and maintenance in areas with explosion hazards can lead
to explosions that can cause serious injuries and even death.

Be certain that there is no explosive atmosphere during assembly and
maintenance.
