2) Fasten the geared motor (axis in the chosen position) to the support
base "A", with the night light facing towards the top, using the two
previously removed screws and lock nuts.
3) The telescopic arm fastening brackets "G" can either be welded to
the fixed frame of the garage door (reinforce the welding area if the
metal sheet is less than 2,5mm thick) or fixed to the frame/wall using
two M8 bolts. At this point slide the tube "H" between the arms of the
bracket "G" and fasten down (don't over tighten) using the supplied
M8 x 25 screws and lock nuts.
To guarantee correct operation the tube "H" with its straight arm
inserted must be able to move within a minimum space of 20mm
between the door arm "C" and the counterweight housing "L". If the
available space is inferior you will have to use a curved arm.
4) Place the tube "H" (with the arm "R" inserted) parallel to the coun-
terweight housing "L" and measure the distance "W" between the
end of the motor shaft "S" and the internal part of the straight arm
"O" as shown in the drawing. Subtracting 63mm from the distance
"W" will give you the overall length of the motor shaft extension tube

(fig.2,3). Follow the same procedure to measure the cutting length for
the other extension tube. Remember to file down the sharp edges
after cutting.
5) Position the support brackets "M" (fig.9) at the same height as the
geared motor axis and drill two Ø 4mm holes with which to fix the
bracket to the garage door framework.
6) Assemble the 36/GLOTG group (fig.2-3) motor shaft extension
tubes, threaded joints and relative supports and then fasten down
the support tubes using the supplied 4,8 x 16 self-tapping screws. Montaggio tubi

the telescopic arm hinge hole "q" with the garage closed "x" and
with the garage door open "Y". Cut the tube "H" and straight arm

"R" to the minimum measured size (minus a play of 20mm).

Remember to file down the sharp
edges after cutting. Reassem-
ble and fasten down the
arms using the supplied
M8 grub screws.
8) Drill the extension tube as
follows:
- Make sure that the garage
door is closed and the geared
motor is free;
- Using a Ø 0mm drill bit make
a hole in the centre of the joint
"N" (fig.2-3) which passes half way
through the tube.
- Insert the Ø 0x50 elastic pin halfway
through the tube.

allow the elastic pin to outcrop the same distance on both sides of
the joint.
9) Check that the door is well balanced by manoeuvring it manually.
The weight of the motor means you will have to increase the counter
weights by 4-5Kg on each side. Compensate the counter weights
until the garage door is perfectly balanced.
Fitting the motor laterally
Once you have decided upon the correct assembly diagram follow
points 1,2,3 and 7 of the previous paragraph. In this case there are
two motor supports and they should be fixed to the extreme right
and left of the garage door maintaining a distance of 65mm from the
counterweight housing as shown in the
drawing. Insert the threaded joint of the
telescopic arm directly into the threaded
shaft of the motor, push it well in,
and fasten down using the sup-
plied grub screw. Check that the
door is well balanced by manoeu-
vring it manually. The weight of
H
the motor means you will have
to increase the counter weights
by about 0Kg on each side.
Compensate the counter weights
until the garage door is perfectly
balanced.

- Position the setting support bracket "d" about 0cm above the
garage door lock (in line with it) and fasten down using 2 rivets.
- Mount the setting screw "C" with its relative nut and lock nut (one for
each motor) and leave a space in order to allow adjustment later.
- Carefully insert the spring mechanism "G" into its seat on the base
"H" so that the tab "F" moves the lever "L" (fig.6a) while it rotates
and then fasten down using the two 4,8 x 13 self-tapping screws "I".
If the unit has been correctly assembled you will be able to tighten
down the two screws without them interfering with the rotation of
the spring mechanism. The spring mechanism moves the lever "L"
into the release position when the cord "N" (fig.6b) is pulled.
- Mount the spring "M" by inserting its hook "P" into the opening "q"
(fig. 6b) and fasten the other end "R" using the 4,8 x 13 self-tapping
screws "O".
- Insert the cord "N" through the hole on the spring mechanism and
then into the corresponding hole on the base "H". Work out the
required length of the sheath "E" and insert the cord. Use a little oil
or grease to extend the lifetime of the cord.
- Pass the cord through the setting screw "C" and fasten down using
the screw "B" of the lock "A" after having tightened the cord and
having wound half a turn around the screw. The M8 serrated washer
placed below the screw will fasten the cord into position.
- The manual release mechanism is working correctly when a 90°
rotation of the door handle corresponds to the alignment of the
marker tab "S" (fig.6b). The spring mechanism cannot go past this
mechanical stop. Use the setting screw "C" if any ulterior adjust-
ments are required.
- In certain cases the spring "M" could develop too much force and
pull back the handle of the lock "A". If this occurs you may remove
the spring "M" (it is not always required) the handle will now remain
in the released position.

Release the cam and rotate it
until the microswitch trips.
- Carry out several trial rotations
to make sure it is functioning
correctly.
- To adjust the cam "A" you may
also insert a flat nosed screw-
driver into the slit "B" and then rotate
the cam in either direction.
