2. Manually raise the door to a nearlyopened position.
3. Pull the travelling cam retaining bracket on the Open Position cam side and rotate the Open Position cam
(Figure 12).
Note: Turning the cam towards the center of the shaft increases door travel.
Turning the cam towards the switch decreases door travel.
4. Manually rotate the Open Position cam until the lever activates the Open limit switch sufficiently so as to hear
the switch click.
5. Release and engage the retaining bracket. Make sure that the bracket engages in the slots of both limit
cams after each adjustment.
6. Manually lower the door to a nearly closed position and repeat steps 3 through 5 with the Close Position cam.
7. Upon completion of all wiring connections, repeat steps 2 through 6 using the "Stop" button for adjustments
of limit switches to their final, exact positions.
Figure 12 Adjusting the limit cams
3.5 MINIMUM SUGGESTED WIRE SIZE FOR CONTROL CIRCUIT
The control circuit operates at 24 VAC. Due to the resistance in the wire used to carry the control circuit voltage, it
is important to use the appropriate wire size with respect to the distance between the operator and the push-
button station.
The chart (TABLE 2) indicating the minimum recommended wire size with respect to the total distance
between the operator and the push-button station. DO NOT exceed the maximum distance. If there are
several push-button stations in series you must ADD all these distances before selecting the appropriate wire
gauge for your operator.
If the wire gauge is not suitable for the distance, problems in operation will be encountered such as chattering
relays and contactor, premature wear of the contacts and possible tripping of the motor's thermal protection.
If a greater distance is required, a long distance interface module is suggested (consult factory).
When large gauge wire is used, a separate junction box will be needed for operator power connection (not
supplied).
Pull the traveling cam retaining bracket
on desired side to adjust cam position

All power wiring to the operator should be installed by a qualified electrician and may vary with respect to conduit
size and type as specified in the National Electrical Code, Article 430, allowing 5% voltage drop. Power must also
be connected in accordance with local codes.

4.7 BRAKE ADJUSTMENT
1. The brake is factory set. However, after extensive use the brake may need to be adjusted.
2. In order to obtain best performance and maximum life, the brake must be adjusted for:
Proper clearance between the brake band and the brake drum when the solenoid is energized.
Correct brake tensioning when the solenoid is de-energized.
TO ADJUST THE BRAKE SYSTEM:
1. Remove the solenoid front cover by slightly unscrewing screws on each side of the frame. (Figure 14)
2. Slightly unscrew the pivot nut using the appropriate key (7/16”) or a nut driver (Figure 15).
3. Press the brake lever towards the solenoid (Figure 14) to adjust the gap between the plunger and the
solenoid body, meanwhile pull the brake adjustment lever away from the motor to put tension on the band
(Figure 14).
4. The gap between the plunger and the solenoid body should measure 1/4” to 3/8” wide (Figure 15).
5. Tighten the pivot nut, recheck the gap and also check the Brake adjustment:
Verify that the brake drum does not rotate by hand
Manually push the plunger onto the solenoid body and verify that the brake drum rotates easily by hands
6. Once the adjustment has been completed, reinstall the solenoid cover.

3.8 ADJUSTMENT AND MANUAL OPERATION OF OPERA-GH OPERATOR
The Opera-GH operator is equipped with an automatic emergency chain hoist disconnect mechanism to operate
the door manually, no floor disconnect is required.
In one simple step
Control circuit interrupted.
Hoist engaged.
Manual operations.
are successively completed by pulling the hand chain in the desired direction:
1. Firmly pull on the hand chain in the desired direction. The first foot pulled will engage the hoist
mechanism and open the electrical control circuit.
2. Continue the traction movement to move the door. If it doesn’t run in the desired direction, repeat actions 1
and 2 by pulling the chain in the other direction (See Figure 16).
3. The automatic hoist engagement system is adjusted in the factory. It may require adjustment in the field.
Adjustment is necessary if no door movement occurs after two feet of pulled hand chain. Turn the adjusting
nut clockwise (see figure 17) by ¼ turn until the hoist engages after pulling one foot of chain. If the nut is too
tight, the manual torque on the chain will be too heavy.
4. Return to the standard electrical operation.
IMPORTANT: To return to electrical operation, pull back 6 inches on the opposite direction of the chain.
WARNING
DO NOT ATTEMPT TO DISENGAGE THE OPERATOR WHILE OPERATOR IS RUNNING. DO NOT
ATTEMPT TO MANUALLY FORCE A MALFUNCTIONING DOOR TO OPEN OR CLOSE. THIS IS AN
EMERGENCY DEVICE AND IS NOT DESIGNED TO OPERATE A DOOR WITH SERIOUS MECHANICAL
PROBLEMS.

4.9 GEAR REDUCER BREATHER AND LUBRICANT
All Gear Head operators are supplied with a Reducer Breather. However, the breather is not mounted at the factory
to avoid leakage during handling of the reducer. All reducers are built with an air-vent hole to receive the Reducer
Breather. To prevent oil leakage during shipping and installation, a metal bolt is placed on the air-vent hole.
WARNING
TO AVOID THE RISK OF HAVING HIGH PRESURE IN THE REDUCER (GEAR BOX) AN OIL BREATHER
SHOULD BE INSTALLED ON THE GEAR REDUCER. FAILURE TO INSTALL THE BREATHER MAY LEAD
TO OIL LEAKAGE FROM THE SEAL AND DAMAGE THE REDUCER.
DRAIN BOLT: is located on the
bottom of the reducer to drain the
used oil. It is advised to bring the
operator down while changing oil.
Drain bolt must be properly
tightened to avoid oil leakage.

16
HOW TO PLACE THE BREATHER IN THE AIR VENT HOLE:
The Breather consists of a Metal Elbow and a Screw-in Plastic Cap with a yellow plug.
The Breather on the reducer should be installed once the gear head operator is mounted. Install the breather
referring to the drawing shown (remove the metal bolt from the air vent hole):
If the air-vent hole is leaning at 60° or more, only the screw-in plastic cap must be used on the air-vent.
If the air-vent hole is leaning at less than 60°, the metal elbow and plastic cap must be used. Using only
the plastic cap will result in risk of oil leakage since the reducer is almost half full.
NOTE: Once the breather is installed, the yellow plug must be removed from the plastic cap to allow
free ventilation of the reducer.
MAINTENANCE:
The oil level in the reducer should be checked at least once a month. False readings can be avoided by
examining the oil on stationary reducer. Remove the breather and with the help of a long screwdriver or a
metal rod, check the oil level by inserting it inside the reducer. Under normal conditions, the oil level must be
near the middle of the drive shaft level. Never mix two different types of oil. If uncertain, change lubricant.
CHANGING LUBRICANT:
After 100 hours of running, a new reducer should be drained, flushed and refilled with proper oil. Thereafter,
oil should be changed at least every 2500 operating hours. Never mix two different types of oil. Be sure to
drain and wash before using another type of oil.
SELECTION OF LUBRICANT:
Lubricating oil must have a viscosity to reduce friction and allow the speed reducer to operate smoothly under
high load and impact. Consult the table below to select the proper lubricant (see table below).
Our gear reducers are normally filled up with oil of S.A.E. (Society of Automobile Engineers) grade 80W90,
where a wide temperature range is expected.
These kinds of lubricants permit extended life between drains. This is due to their increased resistance to
thermal degradation or oxidation.
