BOGE Operating instructions for S 40-2...S 341 / SF 40-2...SF 220 series screw compressors
Changing the V-belt
Check: – 1x per year for damage.
Change: – At visible damage.
The BOGE GM drive system automatically adjusts the V-belt to the correct
V-belt tension in any operating mode.
Maintenance of the V-belt drive is limited to the above mentioned work.
– Switch off the compressor using the OFF button.
DANGER: Risk of injury!
Switch off the main switch and secure it against unintentional switch-on.
Slacken the V-belts:
– Remove cladding on the maintenance side as well as the belt protection.
– Secure screw head of the tensioning device with NW 27 spanner to
prevent it from turning.
– Turn locknut clockwise. Raise the motor in arrow direction until the
V-belts are fully slackened.
Change the V-belts:
– Remove the slackened belts from the belt pulleys.
– Fit new V-belts on the belt pulleys on the motor and compressor.
CAUTION!
The new V-belts must be of precisely the same length.
Only change the V-belts as a complete set!
Tensioning the V-belts:
– Lower the motor again. For this purpose, secure screw head against
turning, then turn locknut counterclockwise and lock by means of the
screw head. The V-belts are automatically correctly tensioned by the
BOGE GM drive system.
– Fit belt protection.
– Reattach cladding on the maintenance side.
