Secure the torsion bar to prevent any rotation, as shown in
Figure 2.15.1.
WARNING: TORSION SPRINGS CAN CAUSE SERIOUS
INJURY! IF YOU ARE NOT SURE, STOP NOW! ASK
TRAINED PERSONNEL.
The number of turns required for each spring is shown on a
paper tag attached to the springs Figure 2.15.2. If the spring
is required to have 7.5 turns for example, these are full turns
and are equivalent to 30 quarter turns. Alternatively, a line is
painted along every spring. If the spring is turned for example
8 times, then 8 lines can be counted along the spring, See
Figure 2.15.3.
WARNING: ONLY USE AUTHORISED WINDING BARS AS
LISTED ON PAGE 5.
Turn the spring by inserting winding bars into the winding plug
holes and wind up in an up and over direction towards the
ceiling, Figure 2.15.4. Once you have completed the amount of
turns required, remove one winding bar then tap the remaining
bar back towards the spring anchor bracket if spring snaking
occurs. Now you can tighten the two set screws with an open
ended spanner, Figure 2.15.5. Again be careful not to over-
tighten the set screws.
Repeat this procedure if there is more than one spring but
remember, always wind the springs, whether left or right hand,
in an up and over direction towards the opening.
WARNING: KEEP HANDS CLEAR OF THE SPRING AND THE
SPRING WINDING PLUG AT ALL TIMES.
Double check that the set screws are properly tightened, before
removing the restraints on the torsion bar.
Test the balance of the door. put the door into the open
position and view along the horizontal tracks. Check that
the clearance in the vertical tracks (5-10mm) is also in the
horizontal tracks. If you find that the door is binding, open out
the horizontal tracks slightly to create the correct tolerance.
Once satisfied that the operation of the door is as near perfect
as possible, check that all nuts and bolts are tight and oil
the springs full length to prevent noise and reduce friction,
‘TAL 5’ or similar oil rich lubricant in a pressure spray can is
acceptable, Figure 2.15.6.
