LIMIT ADJUSTMENT SCREWS ON SAME SIDE FROM MOTOR CABLE
6.1 - Identify which limit adjustment screw controls the up limit and which controls the
down limit (see above diagrams). It is important to note that the arrows by the
limits adjustments screws refer to the tube’s rotation. Thus if the material comes
off the tube on the back side and you are adjusting the limits from the side that the
motor cable is not on (as per diagram 4), the limit adjustment screw with the arrow
facing up controls the down limit and vice-versa.
6.2 - Turning an adjustment screw positive (+) will increase the maximum travel in the
direction that it controls and turning it negative (-) will decrease the maximum
travel. For the adjustment screws on the side with motor cable, turning counter
clockwise is negative (-) and clockwise is positive (+).
6.3 - To set a limit, run the motor in the selected direction.
6.4 - If the motor stops on its own before reaching the desired stop, turn the appropriate
limit screw positive (+). Every 2 or 3 turns of the limit adjustment screw will allow
the motor to travel about 1 inch further. After every few turns of the limit adjustment
screw use the control switch to move the motor to the new limit position. If the mo-
tor does not stop on its own before reaching the desired stop, go to step 6.6.
6.5 - When you are approximately at the desired stop, use the control switch to run the
motor away from the limit 2 or 3 feet and then back. This will allow you to see pre-
cisely where the limit is set. Make small adjustments and repeat.
6.6 - If the motor does not stop on its own at least 6 inches before the desired limit posi-
tion, stop the motor with the control switch. Then turn the adjustment screw in the
negative (-) direction. Conrm that the motor is stopped at the limit and set the limit
as in step 6.4 and 6.5. If the motor is not stopped at the limit, continue turning the
limit adjustment screw (up to 120 turns may be required).
NOTE: The motor has a built-in thermal cut-off. If after several minutes of use the motor
will not run in either direction allow the motor to cool approximately 20 minutes.
