1. Check Motor for tightness

The motor can be checked for tightness with measured air pressure and air flow. Values for a proper tightness are as follows: 45 l/min air flow 10 mbar pressure During pressure check the motor must be complete mounted with all parts.

2. Cracks between cooler housing and cooler duct plates - The cooler inlet has to be checked for cracks and

tightness. The seam between cooler housing and cooler duct mounting plate must be undamaged.

Insufficient sealing on marked area - In case of insufficient condition, the loose seam has to

4 General cleaning instructions The motor must not be cleaned with high pressured water. Risk of damaging the gaskets. - The air channels, the fan and the cooler ducts must be

cleaned regularly to avoid packing of dirt and to ensure sufficient cooling capacity. Clogged cooler ducts increases the risk of motor damages.

- The cleaning interval depends on the dust conditions
