    5 Service and maintenance 5.2.17 Checking v-belts (belt drives) WARNING Entanglement hazard • The protective cover must be correctly installed before re-commissioning. V-belt pulleys should be visually inspected at regular intervals. In case of severe signs of wear, a V-groove and profile gauge should be used as an aid to determine the degree of wear. Dirt on the belt pulley or the belts causes friction losses.

    Industrial gear units – Manual with installation instructions 7.3.3 Minimum starting temperatures Depending on the type of lubrication, the lubricant class, as well as the ambient temperature and additional heating and cooling methods, minimum requirements for the specific oil must be taken into consideration for selection and commissioning.

  • Page 117: Lubricant Quantities

    7 Appendix 7.3.4 Lubricant quantities The lubricating oil quantity stated on the type plate is a guideline value. The precise quantity varies depending on the exact gear ratio and any options (e.g. OSG, OST, OT). Ensure that the oil level is correct. Adjust the oil level as necessary (see Section 5.2.5 "Oil level"). Information After changing the lubricant, and in particular after the initial filling, the oil level may change during the first few hours of operation, as the oil galleries and hollow spaces only fill gradually during operation.
