Procedure
The right belt tension is between 0.4 - 0.5 %. That means that a length mark of 1000mm (applied on the belt with a pen)
on a loose running belt will expand to between 1004 and 1005mm at the right belt tension.
Through turning of the left and right adjustment and tightening screws (hex socket 8mm) to the right the correct belt
tension will be obtained. The belt can be tightened until the shaft does not turn anymore when running belt is being
blocked (see control of running belt tension).
The hex socket must be pulled out of the screw immediately after usage due to risk of injury!

Adjustment (centering) of the running belt
Attention: Dangerous capture area at the tail shaft at the back of the devices (belt re-entry zone).
Take care not to be caught with long hair or loose clothes in the capture area of the tail shaft. For
safety reasons the procedure of adjustment has to be supervised by a second person that can
press the emergency-stop in an emergency.
Before adjustment of the running belt the belt has to be lubricated, if necessary. Lubrication of the belt may have impact
on the centring of the belt.
Adjust the running belt while the device is in operation with the help of the left trimming screw of the running machine.
Use the enclosed hex socket ( 8 mm ). Operate running machine at 12 km/h without elevation. Watch the running belt
for at least 2 minutes. The running belt should be in a centre position on the rear roller (tail shaft).
If this is not the case please pay attention to the following points.
N
Move the running belt to the right by turning the LEFT trimming screw to the right.
N
Move the running belt to the left by turning the LEFT trimming screw to the left.
N
If the discrepancy is only minor the screw should only be turned max. ¼, in the case of major discrepancies with
max. ½ a turn.
N
The running belt has to be observed after each alteration for at least 2 minutes. For the purpose of control operate
the Running-Machine at 5 km/h and 20 km/h.
N
The procedure of adjustment is finished if the running belt stays in the centre of the rear roller (tail shaft) after
having been operated at a speed of 12 km/h for some time (min. 4 min.).
N
Uphill run and different other running styles can lead to locomotion of the running belt. +/- 2cm are to be
considered as an area of tolerance. As long as the running belt returns to the centre at a speed of 12 km/h it is not
necessary to readjust. The running belt remains in the adjusted position for a period of months if it has been done
correctly.
