• Make sure that, during gate travel, no rack elements derail
from the pinion.
• Do not, for any reason, weld the rack elements either to
the spacers or to each other.
• When the rack has been installed, to ensure that it
meshes correctly with the pinion, lower the gearmotor
The operators for chain and idle transmissions require the
installation of a Z16 or Z20 chain pinion.
