Maintenance
9.2 Inspection and maintenance
Grease types
For the standard operating range, a grease for temperatures down to ‑20 °C is normally used for
the initial greasing of rolling bearings. If the machine has been ordered for use in the extended
temperature range of below ‑20 °C, the permissible type of grease is indicated on the lubricant
plate.
Note
Grease quantity control
Only use the specified greases so that the grease quantity control operates perfectly. The data
on the motor lubricant plate is decisive.
Note
Carefully note that it is not permissible to mix different grease types.
9.2.8.4
Cleaning
Cleaning the grease ducts and spent grease chambers
The spent grease collects outside each bearing in the spent grease chamber of the outer bearing
cap. When replacing bearings, remove the spent grease.
Dismantle the bearing cartridges to replace the grease in the lubrication duct.
Cleaning the cooling air ducts
Regularly clean the cooling air ducts through which the ambient air flows.
The frequency of the cleaning intervals depends on the local degree of fouling.
Damage to the machine when cleaning with compressed air or water jets
• Do not direct compressed air or water jets in the direction of the shaft outlet or machine
openings.
• Avoid direct impact of compressed air and water jets on sealing elements of the machine.
Note
Please note the safety instructions for cleaning.
9.2.8.5
Maintenance and repair of machines with type of protection flameproof enclosure
Comply with special conditions for the use. (Page 22)
• Perform maintenance, repair and modification work on explosion-protected machines in
strict compliance with the corresponding national health and safety legislation, the safety
instructions and descriptions in the general maintenance instructions.
