times.
3. Fasten gearbox down firmly to base plate using M10 washers and nuts.
1. Unlock and pull manual override lever fully out to disengage gearbox.
2. Using a 2,5 to 3mm spacer between the pinion gear and the rack, mount the rack
using Tek screws No12x20 (not provided) and screw the rack to the gate starting
from the tail of the gate and ensuring that the rack is mounted level.
(A spacer can also be put between motor and base plate when fitting rack).
NB: Ensure that one of the screws attaching the nylon rack to the angle is in line with the
limit switch spring when the gate is fully closed.
Limit switch actuator mounting instructions

A solid stop must be fitted at both ends of the gate to prevent the gate from moving past its
