GRACE MX II Operating instructions
Tighten the belt by tightening the setting screw
on the dropouts which can be moved
horizontally, with a hexagon socket SW5 (with
spherical head). You can use the open end
spanner SW10 to lock the setting screw.
Press the belt in the middle between the front
and rear pulley downwards on its upper side
with a finger.
The belt is tensioned correctly when the belt can
be pressed downwards by approx. 12mm.
As the tension may vary slightly along the belt, this procedure should be performed while
the belt moves further step by step.
Turn the pedal crank one turn and repeat the measurement. If the tension on the belt is too
high or too low, repeat this procedure until the measurement result meets the
requirements.
Firmly tighten the four hexagon sockets (SW6) right and left on the dropouts as well as the
screw for the torque arm (SW5) (see the torque table).
