Zap JACKSHAFT MOTOR-CONTROL SYSTEM 815-RL - Manual (Page 11)

Mark the hole positions for the Manual Over-Ride
lever on the door track or frame in a convenient
position with the lever held in the horizontal
position. Drill two M5 or 7/32nd of an inch size
holes. (Pic 13).
Fit the M5 screws provided with the screw head
on the inside of the track or doorframe. Fit the M5
nuts.
Secure the hook in the D-shackle of the over-ride
cable. (Pic 14)
Adjust the Over-Ride Lever hook position to
increase, or decrease tension by screwing it in or
out of its bush, see Pic 12. The hook should be
adjusted so that the lever is 90 degrees from the
vertical when the cable slack is taken up. (Pic 15)
When the lever tension is correct push the lever
completely down to tension the V-Belt drive.
