BRAKE CORD/BELT
REPLACEMENT
Remove the instrument cover by loosen the screws
on each side of the cover.
Take the return strap, see fig. 11, and lift up the
weight basket until it locks in its upper position.
Loosen the cord/belt bracket, see fig. 11, and take
away the brake belt from the tension center.
Loosen or cut away the knot or tie up the knot at
the other end of the belt. After that take away the
belt from the bike.
When assembling a new brake cord/belt, first
enter one end into the belt whole in the tension
center, see fig. 11, and tie a knot and let the knot
fall into the bigger part of the hole.
Then assemble the new belt exactly as the old one.
See fig. 10.
NOTE! When replacing the brake cord/belt it
is recommended to clean the brake surface.
See BRAKE SURFACE - BRAKE BELT.

ADJUSTING THE BRAKE CORD/BELT TENSION
At first check that the brake belt is lying correct on the flywheel brake surface.
See fig. 10 and 11.
Put 4 kg in the weight basket. Rotate the flywheel by hand. The basket shall now lift up so the
distance to the flywheel is at least 40 mm. and maximum 80 mm. If this is not the case the brake
belt has to be loosened or tightened a little at the tension center. If the basket is too low shorten
the belt somewhat and if the basket is too high lenghten the cord somewhat.
Lock the weight basket in its upper position and after that loosen the cord bracket somewhat so
that the cord length can be adjusted. Tighten the braket again and release and check if the
measurements above are OK when the flywheel is rotated by hand.
Repeat the above if necessary.
Note: The basket will always give the correct workload wherever it hangs between the upper stop
position and the lower stop just above the flywheel. The measurements above just gives a good
margin - about 30 mm in each direction.
