Step 7 - Gear Rack & Motor Alignment:
• See Fig 16 for recommended gear rack mounting height
• Insert the key and open the manual release bar to put the motor into manual mode, and check that
the motor cog rotates freely by hand (as per fig 16).
• Ensure that the gate drive cog has a minimum clearance of 1-2mm along the entire length of gear
rack fitted to the gate (as per Fig 14)
• Ensure cog and rack are correctly aligned. Under no circumstances should the gate motor drive
cog carry any weight of the gate. It is the task of the gate castors or wheels to carry the weight of
the gate. (As per Fig 15)
• If the gate doesn’t slide freely by hand, adjust gear racks height accordingly until the full length of
gate slides freely by hand
To put the gate motor into manual mode, insert the
key and open the manual release bar as shown
At this stage of final assembly, the cover is removed (not shown) and the power cable is still unplugged.
In manual mode, the gear can turn freely
and the gate can be operated by hand
Gear rack correctly aligned at 90°
to the motor cog
