Operating instructions SPEEDY F4 & F2
To adjust the track proceed as follows:
1. Loosen the aluminium locking nuts on both
sides (AF 41 mm).

locking nut (rear view)
2. Correctly adjust the track by turning the
drive wheel bushing (AF 22 mm). Here it
can be said that: If you turn the drive wheel
bushing in the direction of travel, the track
at the front will become more narrow. The
exact opposite occurs if you turn it against
the direction of travel, the track opens up.
3. Make sure that the distance at the front to
the frame on the right and left is the same.
Distance at front to
frame the same
size on both sides

4. Measure the distance between the drive
wheels at the front and back again at the
axle height (along the markers) so that the
distance between the rive wheels is not
any larger at the front than at the back.
Apart from that, the distance at the back
may not be more than 5 mm larger that at
the front.

5. If all the distances are correct, then use an
open-ended spanner (AF 22 mm) to hold
the running wheel bushing in position and
tighten the aluminium locking nut (AF
41 mm) with a tightening torque of 70 Nm.
