Maintenance
•
Every two to three weeks, crank the engine slowly and pull it again until the
compression resistance is felt.
3.) Jack drive wheels
•
Using wooden blocks, jack up the machine so that the drive wheels are not
resting on the ground. Pay attention to stability!
4.) Subordinate machine
•
To prevent corrosion, protect the machine from weathering. Do not store the
machine in damp rooms, artificial fertilizer warehouses or stables.
5.) Cover the machine with a cloth or similar.
10.6 Checking the V-belt tension from the PTO
To prevent the V-belts from slipping or burning, they must be sufficiently tensioned when
switched on. The tension on the V-belts is provided by a tension spring, which is located
between the activation lever and the Bowden cable under the control console.
As long as the stroke of the shift lever is greater than the distance traveled by the tension
roller, a change in length of the tension spring takes place. The greater the change in length of
the tension spring, the greater the ultimate bias of the V-belts. On the one hand, the tension
spring ensures sufficient pretensioning of the V-belts and, on the other hand, it also serves as
a buffer for possible length changes of the V-belts.
When the PTO is switched on, the length change of the tension spring should be min. 4 mm.
The following relationship applies:
V-belts are lengthening => spring travel is decreasing => preload is decreasing =>
slipping of V-belts => burning of V-belts
V-belts that have burned must be replaced by new ones, as they can no longer transmit
any torque! Only use original manufacturer V - belts!
