11.4.5 Belt tension check
Warning:
Only check the belt tension with the engine off. Remove the spark plug cap. The
scarifier must be tilted to check the belt tension. The air filter must be removed
prior to tilting the machine to prevent soiling it with oil.

as possible.
Should any oil seep back to the air filter compartment, remove it with a dry and
totally lint-free cloth and run the scarifier without the air filter for a couple of
minutes. Don’t forget to replace the air filter afterwards.
Wearing gloves is mandatory.

sufficient belt tension and trouble-free operation of the
blades, a one centimetre distance between them should
remain when pressing the two belt parts together. No
adjustment of the belt tension is required in that case.
When replacing the belt protection cover, verify that it
doesn’t touch the pulley when the blades are engaged.
The slots in the cover provide some play to avoid contact.
