V-BELT, CHECKING AND ADJUSTING THE TENSION
• There is danger of severe accidents, if you perform main-
tenance work at a machine that has not been parked and
secured correctly!
Park the machine on a solid, even surface and secure it,
before you start to perform maintenance work.
1. Before you start maintenance work, park and secure the
machine as described in the chapter "Preparing the Ma-
chine for Maintenance".

is danger of severe injuries by moving parts within the en-
gine compartment!
