2. Remove the plugs from the grease escape holes.
3. Open the grease nipple plugs.
4. Use grease piston to enter speci c amount of grease into the grease nipple.
5. If possible, let the machine run approximately one hour to let the old grease exit. NOTE! It is

Cooling system maintenance
The electric machine cooling system requires certain regular maintenance activities.
The coolant liquid ow direction must be changed yearly. This is done by changing the order of
the coolant connections, or changing the coolant pump direction. The reason for changing the
coolant ow direction is to prevent possible dregs (sediment) accumulating to the cooling system.
The quality of the coolant must be checked yearly. The mixture of water and glycol as well as the
type of the glycol used must be as speci ed. See Chapter Recommended coolants.
