Drive Belt (43)
Lower Drive Pulley (46)
3. Place the new belt first on the lower drive pulley and then on the upper one.
Lightly tighten the tensioning screws.
Insert a screwdriver into the adjustment opening as shown in the picture
below and tension the drive belt by moving the screwdriver. After that, tighten
the three tensioning screws.
4. Check the tension of the drive belt by compressing it in the middle. The drive
belt has the correct tension when it can be compressed by about 5 mm. If the
belt is too slack, it may creep on the wheels and may be destroyed. If the belt
is too tight it will overload the motor and put excessive stress on all bearings.
After that, reattach the drive cover.
