Caution
:
For performing this maintenance, switch the motor off and pull the spark plug
cable from the spark plug.
Caution
:
Leave the tensioning roller to cool down before disassembling it.
Tensioning roller of the blade drive
The roller that tightens the belt in is under extreme pressure :
:
• The runner rotates 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 conse-
quently, damage or breakage of the belt.
How to proceed:
• Disassemble the front protective cover on the left side of the machine. (Read § “15.1
Removing the protective covers” on page 71)
• Loosen the centre bolt (M6) from the tensioning roller, while holding the nut on the back side
of the tensioning roller’s holder in place.
• If there is any serious damage or wear and tear on the tread, the tensioning roller should be
replaced. The tensioning roller can be ordered from an authorised ELIET dealer.
• If the tread exhibits no severe wear and tear, then you should only replace the bearings.
• For stability purposes, this tension roller is provided with two bearings.
• On the front of the roller, you will notice a safety clip, which secures those bearings in the
compartment. Using a special tong, you will be able to remove the safety clip.
• Using an axle and a hammer, the bearings can be tapped out of the compartment. To simplify
this, you can spray some penetrating oil onto the bearings beforehand.
• The replacement bearings can be ordered from an authorised ELIET Service Centre.
• Press the new bearings into the compartment evenly. For this, press on the outer casing of the
