Removal and Re-installation of curtain in guides
1.
Unbolt the hinged front guide plates of both the left and right guides. Swing the front guide
plates open and place them to the side.
1
In the event that only the upper portion is hinged, raise the curtain and bottom bar until the bot-
tom bar front angle is just below the open hinged portion. Then, lift the curtain one end at a
time, out of the guides and set it outside the front guide plates.
2
Lower the curtain slowly and make sure that it does not catch on the guides. To re-install the
curtain, follow the above steps in reverse order. Be sure to close and bolt the front guide plates
prior to putting the door back into operation. Make sure that the guide gap is an even ½” from
top to bottom.
Removal and Re-installation of bottom bar
1. With the curtain and bottom bar supported on a flat surface, remove the bolts which secure the
bottom bar to the curtain.
2. Slip the curtain out of the bottom bar. To re-install the curtain back into the bottom bar, follow
the above steps in reverse order.
If the bottom bar is equipped with an electric reversing edge, be sure to unplug the connector when
removing the bottom bar. In addition, take extreme care not to damage the electric reversing edge
fabric. A puncture would allow moisture to penetrate it, thus causing premature failure of the re-
versing edge
.
Repairs to rubber curtain
– rips or perforations
In order to work on the ripped or perforated area, the curtain must be taken out of the guides and
lowered to the floor. Then, either work on an area supported by the floor or alternatively, a solid,
level surface provided by a heavy table, for example. Refer to Figure 31 and 32 for positioning of
the curtain prior to repairing it.
1. Using a utility knife, set it to a depth that will penetrate the rubber down to the nylon cord centre
of the curtain and cut a rectangular or square section approximately 2" wider than the sides of
the rip or perforation. Be careful not to cut the nylon cord itself (see Figure 31).
2. Using a screwdriver and pliers and starting at one corner of the cut, peel the surface from the
nylon cord centre within the perimeter of the cut.
3. Using coarse sandpaper or a wire brush, remove loose rubber particles from the nylon cord
centre. However, it is not necessary to have the fabric 100% bare.
4. Flip the curtain over to the other side of the rip or perforation and repeat Step 1 through Step 3.
5. From the

" thick piece of repair rubber, cut some pieces to inlay into the prepared areas. Us-
ing a grinder with a sanding disc or a wire brush, roughen-up the inlay surfaces for bonding.
6. Mix the adhesive as per the manufacturer's instructions and apply a liberal coating to the nylon
cord fabric and the rough surfaces of the inlay rubber segments. Allow pieces to dry to the
touch (about 15 to 20 minutes) and apply a second coating. Allow to set until tacky. Place the
inlay segments into position and, using a rubber or rawhide mallet and a steel buckler, impact
the entire area of the patch repeatedly. A high degree of impact ensures proper adhesion.
Clamping is not acceptable. Allow the cement to cure thoroughly (1-

2
to 2 hours) before mov-
ing the curtain.
7. Finally, raise the curtain to an open position, re-insert it into the guides, close and re-bolt the
guides, and resume normal operation.
