12.3.3 Refilling silicone oil:
• Fold in the device as described in
chapter 5. On the underside of the
running belt frame you find two red
openings.
• Pour a few drops of silicone oil
into both openings and wait a few
seconds. Wipe off spilled oil, if
necessary.
• If desired, fold down the running belt
frame again. The oil cannot flow back,
so you can use the device without
hesitation.
12.4 ADJUSTING THE RUNNING BELT
The running belt is tensioned at the factory. However, due to stretching, it may be necessary to re-tension
and readjust the running belt after some time. This is done via screws in the end caps of the running belt
frame, which can be turned with the Allen key supplied.
12.4.1 Checking the tension of the running belt
If the running belt slips when stepping on, when changing speed or already when switching on, it is
probably too weakly tensioned. However, the running belt may neither be too tight, as this increases the
wear of the ball bearings, among other things.
• Ensure that no children or animals approach the treadmill.
• Switch on the device and run the belt at 8 to 10 km/h and observe the run.
12.4.2 Uniform retightening of the running belt
Turn the screws alternately on both sides evenly and carefully about a quarter turn clockwise to
•
increase the tension. Do not stretch too much.
• Check that the running belt is centred and adequately tensioned.
12.4.4 Relaxing the running belt
In rare cases, the running belt may be too tight. Then:
Carefully turn the screw(s) about a quarter turn anticlockwise to reduce the tension.
•
• Check that the running belt is centred and adequately tensioned.
12.4.5 Adjusting the running belt centrally
• If the belt does not run centrally, the tension must be increased on the side to which it is drifting.
(drifting to the right => tighten slightly on the right or relax slightly on the left;
drifting to the left => tighten slightly on the left or relax slightly on the right)
• Retighten by a maximum of a quarter turn, then check the central running again.
Example: Retightening the right-hand
bolt of the running belt
