BELT TENSION/BELT REPLACEMENT
2
Refit the wing nut and the washer.
These are necessary for carrying out the
adjustment.
If the belt jumps off the pulley or if it breaks, the
cutter and the motor can continue to rotate several
minutes. It can be difficult to see whether the motor
and the belt are rotating.
Ensure that the power is disconnected before
opening any protective covers or carrying out any
servicing on the machine.
The cutter head is run by a double-pole, threephase
motor with 2800 rpm. The number of revolutions is
geared up by a Poly-V belt transmission. The belt has
to be tensioned or replaced after some time of use.
When the belt starts to squeak during operation, it
should be tensioned or, if necessary, be replaced. If
there are visible damages on the inside of the belt, it
has to be replaced.
The belt is loosened and tightened as follows:
1
Loosen the wing nut on the top of
the belt guard and them remove the
guard from the motor.
