Control and tightening of the running belt
The belt can loosen after some time of use or when it has been adjusted in a wrong way, so that a backlash occurs with
every step between the driving shaft and the belt (slowing down of the belt at weight application through the step).
In this case check the belt tension as follows:
N
Visual inspection of the surface for cracks. In case of a crack
replace running belt immediately.
N
Open the motor hood in the front. Take care that nobody gets
their hands into the motor.
N
Now press the "START/Enter" key to get into manual mode
and select with the help of the "+"/"-" keys a speed of 1 up to
1.5 km/h.
N
Stand on the running belt (if necessary with 2 people). Hold
on to the side handrails with both hands and try to block the
running belt by stemming yourself against the running belt
rotation with your feet.
N
Try to block the running belt for max. 10 seconds. The driving
shaft and the motor shaft should not be turning during that
time. Otherwise the running belt has to be tightened (or the
driving belt).
If the running belt is being blocked for too long, then the motor regulation can switch off because
of over current, which will be indicated by an error display. In this case, switch off the device for 5
minutes and then switch it on again. The belt tension should not have more than 0.5 %, for
otherwise it could lead to damages on the belt, on the shafting or the bearings!
For models with a running surface up to 190 x 65 cm the belt is tightened with a hex socket (8 or 10 mm) at the rear
drive shaft [2]. All bigger models are tightened at the front drive shaft [5]. Mark of 1000 mm [1] applied when belt [4]
absolutely loose. Tighten belt, until mark expanded up to between 1004 and 1005 mm (= 0.4 to 0.5 %).
