d) Setting the Tooth Backlash

The distance between the main gear (C) and motor pinion (D) must be as low as possible without the gears being too
tight. How to achieve this?
• Turn the two screws (A) of the gear cover (B) out; take
off the gear cover.
• Loosen the two motor attachment screws (E) slightly.
Then push the motor with the motor pinion (D) in the
direction of the main gear (C) with light pressure.
The motor pinion and the main pinion now engage
without clearance. However, this is not perfect for the
service life of the gears!
• Put a thin paper strip (F) between the motor pinion (D)
and the main gear (C). Then manually turn the main
pinion so that the paper strip (max. 80 g paper!) is pulled
in between the two pinions.
The pressure of the paper pushes back the electric
motor by the required measure.
• Now tighten the motor's attachment screws (E) again
in this position.
• If you then turn back the main cogwheel so that the pa-
per strip can be removed again, both cogwheels should
have the correct distance.
Ideally, the motor pinion should be as close as possible to the main pinion without the teeth touching and
the gears therefore being tight.
If the cogwheels (motor pinion and main cogwheel) are too far apart, the main cogwheel teeth will be
virtually shaved off by the motor pinion after a few seconds - this will void the warranty/guarantee!
If the motor pinion presses against the main cogwheel (teeth are running without play), this will decrease
performance, increase power consumption (the motor already requires lots of power to turn the main gear)
and lead to premature wear.
