Rotor vane height wear
To inspect the rotary vane for height wear, remove the
combination air filter and suction line, resp.
Press the rotary vane in the rotor gap through the
oblong hole which becomes visible. Measure the depth
to the rotor surface by means of a depth gauge (see
).
Figure 7-4:
Check rotor vanes for height wear
The depth must not be more than 5
mm!
If the wear limit of 5 mm is reached, the rotor vanes
must be replaced. (See the separate instruction
manual).
Make the first wear check after about 6 months, then
every 3 months (if the machine run time is about 3 - 4
hours daily).
