Belts 2 and 3: engine crankshaft - speed drive
• To replace the belt, the protective cover must be removed
first (read § 15.1).
• Next, demount the plate at the back of the belts after
undoing the four M8 bolts.
• Undo the two screws in the belt pulley of belt 3 - this will allow you to pull back the pulley
somewhat. You can now loosen the belts from the pulley and remove the belt..
Caution:
Do not forget to check the belt tension after placing back the belts.
Do not forget to place back all the covers before you start operating the
machine.
11.4.5 Replacing the belt tensioning roller
The metal runner that tightens the belt the moment the All-in-one
TM
control lever is pushed is
under extreme pressure:
• the runner runs against the belt at 2300 RPM.
• Due to friction with the belt the latter becomes very hot; lubricants become liquid and will leak
from the bearings as a result.
• During periods of drought, dust will inevitably develop when operating the machine. Stand and
dust will find their way into the bearings and cause damage.
Due to the combination of these three factors the tensioning roller is sensitive to wear. Regular
lubrication can counter accelerated wear. As soon as the bearing starts to make a growling
sound, we recommend to replace the tensioning roller as a precaution. Failure to do this will
result in blockage of the tensioning roller and consequently, damage or breakage of the belt. The
belt may also damage the magnetic sensor when it breaks.
