NOTE! When assembling the upper gear housing it is
very important that the gears are correctly positioned
in relation to each other. This applies not only to the
backlash between the gear teeth but also to the gear
teeth contact. Correct gear teeth contact spreads the
load to which the gears are subjected over a larger
area of the gear tooth. This preventing gear break-
down and abnormal wear and at the same time provid-
ing a quiet operation.
