1) To ensure optimum lubricating properties, preheat the drive to an operating temperature above -30 °C.
CLP = mineral oil
CLP PG = polyglycol oil
E = ester oil, organic oil (bio oil / risk of water pollution, class WGK1)
PAO = poly-alpha-olefin oil
CLP H1 = physiologically safe oil (USDA-H1 approval)
10.3
Replace bearings
The bearing service life is finite, greatly depends on the operating conditions and therefore
cannot be calculated reliably. In the operating conditions specified by the operator, bearing life
can be calculated. Changes in vibration and noise pattern are an indication that an immediate
bearing replacement is necessary.
10.4
Checking the gearbox for leaks
Note
Due to the inherent principle of operation, oil mist can escape from a breather valve or labyrinth
seal.
