FITTING THE MANUAL OVER-RIDE
LEVER MECHANISM
The position of the cable post should be assessed
next. The Cable Post, which secures the Bowden
cable outer sheath, is fixed to the door track or
frame using two M6 flat head screws and flange
nuts supplied. Drill two M6 or 1/4 inch holes in the
door track or frame in a position at least 25mm or
one inch higher than the fully extended position
of the outer cable, to allow movement of the
upper section of the outer sheath. (Pic 11)
When fitting the Manual Over-Ride lever it is
preferable to position the lever relative to the
position of the end of the inner cable of the
Bowden cable with the lever in the horizontal
position.
When fitting the Over-Ride Lever ensure that the
lever is horizontal when the cable tension is taken
up. It is important that sufficient tension is
achieved to ensure that the drive belt does not slip
on the motor pulley. The lever should require
reasonable hand pressure to lock it into place. The
lever hook position is adjustable to allow the
Super-Drive V-Belt to be correctly tensioned.
(Pic 12)
Prepare the Manual Over-Ride lever by slackening
the lock nut on the screw hook adjuster and
unscrew the hook to a position where 75% of the
screw thread is exposed on the outside of the boss
nut. Slip the lever hook onto the D shackle whilst
holding the lever in a position 90 degrees from the
vertical with the lever base against the track or
frame.
