The gearbox is intended for installation on motors that:
- correspond to the design B5 (in the event of deviations, consult our Customer Service
department [Technical Customer Service department]).
- have a radial and axial runout tolerance according to DIN EN 50347.
- have a cylindrical shaft end with tolerance class h6 to k6.
For motor shaft diameter 55 mm and up, m6 is also permissible.
Screw connections between gearbox and attached component such as motors have to be
calculated, dimensioned, mounted, and tested according to current technological standards. Use
the VDI directives VDI 2862 sheet 2 and VDI 2230 for example.
The tightening torques recommended by us can be found in Chapter 9 "Appendix".
Deviating from the recommendations in Chapter 5 "Assembly", washers may be used if the material
of the screw surface features a too low interface pressure.
The hardness of the washer needs to match the property class of the screw.
Take into account the washer for the screw calculation (joint, additional compression set,
surface pressure under screw head and under washer).

Reasonably foreseeable misuse
Any use is prohibited if
- it contradicts the requirements of chapter 2.3 "Intended use",
- it exceeds the permissible technical data, e.g. speed, force and torque load, temperature,
service life (see also chapter 3.4 "Dimensions and performance data").

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 cause hearing damage. The continuous noise pressure level may vary
according to product type and gearbox size:
Information about your gearbox is available in the customized performance data (X093–D...),
in the catalog under www.wittenstein-alpha.de, 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:
Use a calibrated torque wrench to tighten and check all screw connections for which
tightening torques have been specified.
Solvents and lubricants
are flammable, can cause skin irritation, and can pollute soil and water:
In case of fire: Do not use a jet of water to extinguish.
Suitable extinguishing agents are powder, foam, water mist and carbon dioxide. Observe
the safety instructions of the lubricant manufacturer (see Chapter 3.5 "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.
