Maintenance and service
V-belts and V-belt pulleys
– Check tension of the four V-belts (
2
). For this purpose, apply a load of 8 kg side-
ways to each V-belt in the centre between the pulleys, using a special scale. If the
tension is correct, the belt deflection is approx. 10 mm.
The illustration shows KS 475
– If the V-belts are too loose or too tight, loosen the four safety screws ( 3 ) on the
upper V-belt pulley and tighten or release the V-belts using the adjusting screw
with lock ( 4 ).
– Then retighten the adjusting screw and the four safety screws on the upper V-belt
pulley.
– Check tension of the four V-belts again. If tension of the V-belts is still not correct,
repeat the process.
– Once the tension of the V-belts is correct, mount the protective cover again and
carry out a test run.
7.3.2 Replacement of V-belt pulleys
The V-belt pulleys of the machine must be visually inspected for damage every 50
operating hours. If the V-belt pulleys are damaged, replace them in good time.
If the machine is to be operated with a different PTO speed of the tractor, the V-belt
pulleys must be adjusted beforehand according to the desired PTO shaft speed. On
the KS 475: 540 rpm, 750 rpm or 1,000 rpm. On the KS 490: currently only the variant
with an input PTO shaft speed of 1,000 rpm.
DANGER
Risk of fatal injury and damage to the machine.
If the haulm topper is driven with the PTO shaft speed set too high, there is a risk of
parts flying away from the machine.
Always ensure that the maximum permissible input PTO shaft speed of the machine is
not exceeded.
In order to replace the V-belt pulleys, proceed as follows:
– Switch off the machine and prevent it from restart.
