Make rack level and mark the rack’s mounting holes
(three holes)
on the gate.
4. Weld the rack nut on the gate as mark and connect the rack to the gate using the bolt provided. Before
weld, please keep 1.0mm space between the rack and the gear to avoid the weight of the gate effect on the
opener.
Installation of the Magnets
Before install limit switch, make sure the gate opener is put in manual operation. (the clutch connected with
gear shaft is disengaged) and the mains power supply is disconnected.
Position the S&N Magnet Components approximately on the gate and move the gate by hand to fix them in
place.
