B) Setting Tooth Backlash - Reely Firestar Bedienungsanleitung

b) Setting Tooth Backlash

Tooth backlash has to be adjusted when the electric motor, the motor pinion or the main pinion is exchanged.
Loosen the attachment screws of the electric motor so that you can move the motor with little pressure (the motor must
not be loose!). The motor pinion and the main pinion now engage without clearance.
Insert a small paper strip (thin letter paper) between the motor pinion and the main pinion.
Now move the main pinion by hand so that the paper strip is pulled in between the pinions.
The pressure of the paper pushes back the electric motor as far as necessary. Now fasten the attachment screws of
the motor in this position.
When you turn back the main pinion afterwards so that the paper strip can be taken out again, the two pinions will have
the right distance to each other.
If the motor pinion is too close to the main pinion, the drive does not run smoothly and performance is lost.
In addition, the motor and the speed controller overheat which can lead to damage to these components.
If the distance between the motor pinion and the main pinion is too great, the teeth of the two pinions might
slip which immediately destroys the main pinion. Loss of warranty/guarantee!
