Adjustment (Centring) Of The Running Belt - h/p/cosmos 150/50 Operating And Service Manual

Procedure
The correct belt tension is between 0.4 - 0.5 %. Mark a line of 1000 mm [1] when the belt [4] is completely loose.
Tighten the belt until the line is expanded up to 1004 - 1005 mm (= 0.4 to 0.5 %). 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 deviation shaft [2]. All bigger models are
tightened at the front deviation shaft [5]. The correct belt tension is achieved by turning the left and right adjustment and
tightening screws (hex sockets) clockwise. The belt can be tightened until the shaft no longer turns when the belt is
blocked.
The allen key must be pulled out of the screw immediately after usage due to risk of injury!
The oversize machine h/p/cosmos saturn 450/300rs has an automatic belt tightening system with motors and sensors
and does not need to be tightened manually.

8.6 Adjustment (centring) of the running belt

Attention: Dangerous gap/capture area at the tail shaft at the back of the device (belt re-entry
N
zone). Take care that long hair and loose clothing are not caught in the gap of the tail shaft.
For safety reasons, the adjustment procedure must be attended by a second person who can
N
immediately press the emergency stop button in an emergency.
Switch off the running machine and pull the mains plug before intervening.
N
In case of any maintenance work on the treadmill, ties have to be removed. The tie might be
N
pulled in and the person wearing will be strangled.
If necessary, lubricate the running belt before adjusting it. Lubrication 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 the running machine at 12 km/h without elevation. Monitor the running
belt for at least 2 minutes. It should be in a centre position on the rear roller (tail shaft).
If this is not the case, please do the following:
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 turn; in the case of major discrepancies
N
turn the screw max. ½ turn.
Observe the running belt after each alteration for at least 2 minutes. For control purposes, operate the running
N
machine at 5 km/h and 20 km/h.
