The backroom distance is
measured from the back
of the door into the
site, and should be at
least 18" more than the
height of the industrial
door.
step one:
A minimum side room of 4" should be available on each side of the
door on the interior wall surface to allow for attachment of the
vertical track assembly. The rough opening should be the same size
as the door.
Headroom is the space needed above the top of the
door for the door, the overhead tracks, and the
springs. Measure to check that there are no
obstructions within that space,20" headroom
required at least for industiral door.
vertical tracks
Please keep in mind that the clearance
between the door edge and the vertical
track inside edge is 20mm-25mm
(each side,grey part).
On the inside of the opening should be framed with wood
jambs, 2" x 6" if possible. The side
jambs should extend to approximately the same height as
the headroom required.

sizes,then install the protection track
I and vertical track J accordingly: THE
VERTICAL PROTECTION TRACKS MUST BE
PARRLLEL.In other words,the distance
between the track must be the same at
the top and at the bottom. The top of
the vertical tracks must be level as
compared to each other.If possible
please use the gravity dropper to test.
The tops of the vertical tracks must be level with each other.If two vertical
tracks are not level,cut the bottom of one of the tracks or lift the other.

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.
12

final checkings:
a,re-adjust torsion spring if necessary,always close the door and
latch before adjusting.
b,lubricate all moving parts.
step eight:
c,if door doesnot work
easily,double-check the
installation process
especially the step ten &
eleven.
d, make sure spacing of
track is correct and that
door is not binding any
place.
balance the door
with the level

1, the door becomes very heavy and only goes up harfway.
The torsion spring(s) has been installed backwards
2, the door opens very fast and is hard to bring back down.
The spring has been wound too much,it is too tight.Adjust the tension according to the type of spring.
3, the door closes fast and is hard to lift.
The spring has not been wound enough,it is too loose.Adjust the tension according to the type of spring.
4, the door works well but it goes back up 2 to 3 inches.
The spring is a little too tight.Adjust the tension according to the type of spring.
5, the door is hard to open at first.
The weatherstripping is too tight.Loosen it and place it a little farther from the door(the base of the
weatherstripping should be at about 1/2” from the door)
6, the door is hard to open at the end.
The horizontal tracks are not perpendicular with the axis of the door.Use a tape measure to check this.
7, the top panel does not close completely.
Adjust the position of the upper brackets.
Troubleshooting
8, The door slanting as it moves:
The cable tightness of the two sides of the door is not the same --- Readjust the winding drum
9, louder noise as door moving:
a, Hardware is not fully tightened --- Fully tighten them
b, The curved power arm of the motor is not aligned with the door center --- Adjust the arm to align it with
the door center line
c, The two side tracks are not parallel to each other --- Adjust level, vertical tracks to keep them
d, Didn’t lubricate the hinges and the winding drum --- Lubricate the hinges and the winding drum

Maintaineance
A, The door - clean door surface with a mild household detergent(as you would use for your car) with the brush.
Thoroughly rinse the surface with a garden hose. Avoid abrasive cleaners(ex.:Spic’n’ Span) or strong liquid soaps.
B, Weatherstripping – The weatherstripping is make of quality P.V.C. rubber and therefore should be cleaned with an
all-purpose vinyl cleanser,Lubricate the weatherstripping every 2 months(more frequently for high usage door) with a
silicon-based oil. Don’t use petroleum-based oils as this will cause loss of elasticity.Petroleum attacks the
rubber and decreases its flexibility.
C, Track,hinges,rollers – Lubricated the rollers(Do not lubricate nylon rollers) and hinges with a small amount of
light household oil.For the track,use a small amount of grease (as you would use for your car).removing the old grease
with a rag.Apply this grease primarily in the curve of the track.Using grease will result in the quieter operation
of your door(as both the rollers and track are steel). To replace bent hinge(s) or broken roller(s). No more than
1 hinge is to be removed from the door at any given time.
D, Automatic door opener – Lightly lubricate with the light household oil.Carefully read the instructions
provided by the manufacturer.
E, Open and close the door manually once a month to check the balance system and if non-smooth move occurs.
Please invite the qualified maintenance staff to repair it immediately when you find any problem.
F, Warning – Every 3months disconnect the opener(pull the cord) and open the door by hand several times.If you have
dificulty opening the door,your opener will have the same difficulty. We suggest don't attempt to make repaires on
your garage door without the assistance of a qualified professional door techinican.
G, For your security – The spring assembly,the hardware attached to it and the cables are under extreme tension.
Never attempt to loosen them unless all tension is first removed from springs. Always call your door dealer.
