WARNING: WINDING THE TORSION SPRING CALLS
FOR EXTREME CAUTION : CARELESSNESS COULD
LEAD TO SERIOUS INJURIES.
WARNING:THIS PART REQUIRES THE MOST
ATTENTION ON SAFETY.
Loosen the set screws one the
winding cone of the spring,and then
using the winding bar(not included)
to wind the spring by truning the
winding cone TOWARD THE CEILING.
The wire must point in the same
direction as you are winding.
N.: Always wind toward the ceiling.
Note: wind the spring 2 ~ 3 turns
first, then make the complete
turns as recommended:
door height 2100mm 6turns
door height 2400mm 7turns
door height 2700mm 8turns
Then tighten the set screws of the
winding cone(add half a turn after
feeling a pressure on the shaft.Do
not forget to tighten the pressure
screw before taking out the winding
bars ).
The winding bars must have the same
diameter as the holes on the
winding cone and must be pushed in
as depth as possible into it.
NEVER USE SCREWDRIVERS FOR THIS
STEP.
step seven:
PLEASE MAKE SURE THE DOOR IS IN
CLOSED POSITION.
Remember that each hole on the winding cone is one quarter of a
turn. The number of turns are indicated on the red line affixed
on the spring.
NEVER REMOVE A WINDING BAR OF ITS HOLE UNTIL THE OTHER WINDING
BAR IS IN PLACE AND THAT YOU ARE HOLDING IT FIRMLY. YOU MUST BE
VERY CAREFUL AT THIS POINT.
Once this operation is completed, remove the locking pliers from
the shaft,then only unlock the door, open and close the door
slowly manually.You can now check if the door is well-balanced;
ideally, it should stabilize where you stop pushing it up or
pulling it down.
If the door is heavy to lift, increase the torsion spring
tension. If the door goes up too fast, decrease the torsion
spring tension. Add or delete 1/4 turn at a time, alternating
torsion springs. Recheck the balance. Repeat this procedure
until the door rolls smoothly with a satisfactory balance.
