Pinning the Door 

9

Use bolts or pop-rivets (not supplied) to hold the curtain to
the door drum.

1. Pull the release cord down and across to engage the ball into 

the cup. Close the door manually. Pull the release cord across  
and release to re-engage the opener.

2. Try to manually open the door with the opener engaged. 

Any excess door curtain may balloon out from the top of 

the drum.

3. To remedy any ballooning place gutter-bolts or pop rivets 

(not supplied) 75mm up from where the curtain leaves 
the roll. Secure these through the curtain into the 
drum wheel at each end of the curtain.

• Thread one end of the rope through the hole in the top of the 

red handle so “NOTICE” reads right side up as shown. 
Secure with an overhand knot at least 25mm from the end of 
the rope to prevent slipping.

• Thread the other end of the rope through the link on the 

emergency release cable.

• Adjust rope length so the handle is no higher than 1.8m 

above the floor. Secure with an overhand knot. If the door is 
greater than 2.5m in height the Release Cord Extension kit 
accessory is required.

NOTE:

If it is necessary to cut the rope, heat seal the cut end 

with a match or lighter to prevent unraveling.
