7.4 Checking and tightening the drive belt
The tightness and the condition of the drive belt must be checked at least annually at the beginning of each
mowing season, and depending on use, a few times during the season. A belt that is not at its correct
tightness may not necessarily be apparent to the user, but sudden slipping or breaking of the belt may lead to
hazardous situation or damage to the mower or the blades.
To check the belt, remove the protective cover
from the top of the mower.

Push the belt horizontally at its longest section
between the pulleys with a force of about 50-
80 N. This equals to the force of about 5-8 kg
weight.

The belt should move about 5-10 mm when
the load is applied horizontally. Check that the
belt is tightened correctly and not too much as
well.

Check the condition of the belt visually; if the
belt is clearly worn or material has come off,
the belt must be replaced.
If necessary, the belt is adjusted by moving the
belt pulley.
1.
Loosen the four bolts holding the pulley
base at the other end of the belt.
2.
Tighten bolts 2, until the belt is correctly
tightened.
3.
Tighten the four retaining bolts. recheck belt
tightness.
4.
Refit the protective cover.
Check the synchronization of the blades after tightening the belt and replace all protective
covers and guards before using the mower.
