Hi all
I recently bought a 2nd hand but hardly used Ferm 16/500 9 speed bech drill.
I haven't had call to really use it yet although it powers on fine.
I have opened the case that houses the pulleys and there are 3 sets of wheels with belts going from each outside set to the inner set of wheels.
I can't tell how to move the pulleys to change the speed. If I can somehow slacken them then I can play a bit and figure out which combination of pulley/wheels is the fastest and slowest speed etc
Can someone tell me how to slacken and move the pulleys? There doesn't appear to be any screws labelled up for releasing tension
Hope I've been clear. Have never used a drill like this before
