ROLLER DOOR
We suggest you record your full Key letter and Number on the front of this manual and if replacement keys
are required they can be obtained from your nearest B&D office, simply by quoting this number. If the keys
have been lost and the number not recorded, it can be found stamped into the locking arm at the back of the
mechanism.
NYLOFELT
® On no account should you use grease or oil in the door guides or on the Nylofelt® running
strips – the grease or oil will clog the Nylofelt® and spoil the operation of the door. An occasional wipe with a
cloth dampened with mineral turps or methylated spirits, down the inside of each guide, is very beneficial in
removing any trace of grease or dirt.
After the guides have been cleaned, a silicon spray may be used in the guides.
NOTE: WD40 or similar oil based sprays are not silicon and should not be used.
Care should be taken not to damage the Nylofelt®, however, if Nylofelt® is cut or damaged, a lighted match
should be used to quickly seal the ends of the nylon braiding, so as to stop any further deterioration.
Regular maintenance required
B&D recommends that you check the operation of your Roll-A-Door® at least every six months (more regularly
in extreme environments or frequent use). The effort required to manually open and to manually close the door
should be about the same (if door has an automatic opener, put into manual mode before testing door). If the
door is difficult to operate in either direction (up or down) then check:
1) that the Nylofelt® running strips on each side of the door have not slipped from the edge and are jamming
the door;
2) that the door is running correctly in the guides and the guides are straight and perpendicular; and
3) that the inside surfaces of the guides are clean and free of obstructions. (see paragraph on care of
Nylofelt®)
If you have checked these (and corrected where necessary) and the door is still difficult to operate, then your
door will need a service to adjust the spring tension and possibly other operational parts of the door. This
service should only be carried out by an experienced door technician, using the correct tools.
If you have an automatic opener fitted to your door, it is particularly important that you ensure the optimum
operation of the door, otherwise you may reduce the effective life of the opener.
To keep your door running well, it is recommended that your door be serviced, by an experienced door
technician, every 12 months (more regularly in extreme environments or frequent use), or earlier if required.
Spring tension
It is natural for springs to lose tension over time. When spring tension is adjusted or when your door is first
installed it is usual to apply a little more tension than is required for balanced operation, to allow for the normal
“settling in” of the springs.
