8. Commissioning 

 
 

The commissioning 

(taking up operation in accordance with the intended use)

 of the 

PowerGear

 gear unit is  

prohibited until it has been determined that the machine or plant complies with the provisions of the EU machine 
directive. 

 

Before commissioning check the correct attachment of the transmission parts.  
 
Check the oil level 
 
Do not deactivate monitoring and protection devices, not even during test operation. 
 

The use of an aeration and ventilation filter is not necessary for gear units up to P110 / X110,  
for gear units from P140 / X140 or bigger, we recommend that it be used as soon as the gear units  
exceed operating temperatures of 60°C. 

 
The first start-ups must be carried out without load and at low speeds, until it is ensured that all roller bearings, 
bevel gears and shaft seals are wetted with oil, then increase speed to approx. 500 min

-1  

After approx. 30 minutes, gradually increase speeds until the operational speed is reached, running-in time at 
idle approx. 90 minutes. 
 
During start-up and run-up pay attention to running noise and temperature development particularly at the  
bearing points. In the case of unusual running noise, shut down machine and identify fault. 
See Section 10: "Faults, causes and remedies." 
 

Apparent leakage at the shaft seal rings   

Grease emerging from the lubrication in the shaft seal rings is not an oil leak.  
This is an 

apparent leakage

, until the remaining lubricant has become regulated.  

Wipe off apparent leakage and continue to observe. 
 
 
 
   

   

 

Attention against damage to gear unit: 

If the new gear unit is started up too quickly, the bearings may overheat,  
and the tooth flanks may be insufficiently lubricated. 
 
It is necessary to allow the gear unit to run-in in stages! 

 
 

   

 

Warning

Risk of burns! 
Possibility of severe burns on hot surfaces (>55°C).  
Wear suitable gloves and protective clothing.
