6.1.1 Lubrication and Maintenance
When the mixer is used regularly, the varispeed system must be lubricated approx. once
per month.
When the mixer is used intensively or often used without changes in speed ,the lubrication
intervals should be shortened.
Start the mixer and increase the speed up to approx. 50%. Stop the mixer and take off the
top cover of the mixer by removing the 2 screws.
On top of the shafts of the pulley sets there is a grease nipple, one on each pulley set.
Press the grease through the grease nipples until the grease gun feels hard, or until grease
is pressed out between the shaft and the pulleys.
Grease for the shafts of the pulley sets: ESSO NEBULA EP1 or EP2, or another ball bear-
ing grease NLGI 1or NLGI 2.
Put the top cover back and remember to put in the 2 screws securing the cover.
The mixer must not be started until these screws are mounted.
Start the mixer and set the speed back to low speed.
Stop the mixer and fill up the grease gun with new grease to be ready for the next lubri-
cation.
