MAINTENANCE
The following suggestions will keep the
door working efficiently.
1. Do not grease or oil the guides.
2. Periodically clean the inside of the
guides with white methylated spirits or
similar and spray with silicone spray or
car/furniture polish.
3. It may be necessary to lubricate the
locking mechanism via the key hole
using graphite dust lubricant if operation
becomes difficult.
4. Your door should be washed with a
quality car shampoo at least every 2
months to prevent the build up of dirt,
salt and other corrosive substances. If
your door is installed within 2 miles of
the sea, your door should be cleaned in
this way
at least monthly.
WARNING! DANGER! HIGH
SPRING TENSION CAN CAUSE
SEVERE INJURY OR DEATH. REPAIRS
OR ADJUSTMENTS MUST BE MADE
BY TWO PEOPLE USING PROPER
TOOLS AND INSTRUCTIONS.

FINAL SPRING TENSION ADJUSTMENTS
(SEE FIGURE 6)
AS A PRECAUTION, ATTACH A PIPE
WRENCH AT THE OPPOSITE END TO
BE WORKED ON AND ENSURE IT IS HELD
TIGHTLY BY ANOTHER PERSON.
(a) One ‘U’ bolt clamp should be selected to
loosen first and the other side should remain
fully tightened. The remaining tight ‘U’ bolt
clamp will retain the existing tension when
the door is fully open (rolled up). However,
as a precaution a pipe wrench must be also
be attached to the axle at the opposite side to
be worked on and held tightly by one of the
installers.
THIS OPERATION SHOULD NOT BE
ATTEMPTED WITH THE DOOR IN THE
CLOSED POSITION AS THE TENSION IS
VERY MUCH GREATER AND COULD LEAD
TO DAMAGE OR SERIOUS INJURY.
(b) Loosen but do not fully remove the selected
‘U’ bolt clamp.
(c) One person should then grip the axle on
that side firmly with an 18” pipe wrench.
(d) The other person should then move to the
other end of the door roll and with an 18”
pipe wrench, grip the axle firmly. Loosen but
do not fully remove the other ‘U’ bolt clamp
until the axle is free.
(e) To increase tension pull down on the pipe
wrench and to decrease tension allow the pipe
wrench to move up (see figure 6).
(f) Fully tighten adjacent ‘U’ bolt clamp while
holding tension with a pipe wrench. Do not
release pipe wrench until ‘U’ bolts are tight.
(Ensure that it never slips as this would cause
loss of tension and possible injury or damage
to door).
