Setup and Installation
The AXA Model 7508 door closer is designed for surface mounting. A detailed A3-sized installation template is included to facilitate correct positioning and drilling.
- Preparation: Ensure the door and frame are clean and free from obstructions. Determine the desired mounting position (push side or pull side, standard or parallel arm installation). Refer to the included A3 installation template for specific measurements and drilling points.
- Marking: Use the provided A3 template to accurately mark the drilling points on the door and door frame.
- Drilling: Drill pilot holes at the marked positions according to the template's specifications.
- Mounting the Closer Body: Secure the main door closer body to the door or frame using the supplied mounting hardware. Ensure it is firmly attached and level.
- Attaching the Slide Arm: Attach the slide arm to the door closer body and the slide channel to the door frame. Ensure all connections are secure.
- Initial Adjustment: After installation, perform an initial check of the door's closing function. Fine-tune the closing speed and end stroke as described in the "Operating" section.

Operating and Adjustments
The AXA Model 7508 offers adjustable closing speed, end stroke, opening damping, and closing delay to suit various door types and user preferences.

- Adjustable Closing Speed: This setting controls how quickly the door closes from its fully open position until it reaches the final closing phase. Use a hex key or screwdriver (depending on the model) to turn the adjustment valve. Turning clockwise typically decreases speed (slower close), while counter-clockwise increases speed (faster close).
- Adjustable End Stroke (Latching Speed): This controls the speed of the door during the last few degrees of closing, ensuring it latches securely without slamming. Adjust this independently from the main closing speed.
- Adjustable Opening Damping (Backcheck): If present, this feature provides resistance when the door is opened forcefully beyond a certain point, preventing damage to the door or wall.
- Adjustable Closing Delay: If present, this feature holds the door open for a set period before it begins to close, useful for high-traffic areas or for allowing passage of equipment.
Always make small adjustments and test the door's operation after each change to achieve the desired closing behavior.
Maintenance
The AXA Model 7508 Door Closer is designed for durability and requires minimal maintenance. Regular checks can ensure optimal performance and longevity.
- Cleaning: Periodically wipe the door closer body and slide arm with a soft, damp cloth to remove dust and dirt. Avoid abrasive cleaners.
- Fastener Check: Annually inspect all mounting screws and fasteners to ensure they are tight. Re-tighten if necessary.
- Functionality Check: Test the door closer's operation periodically to ensure the closing speed and end stroke remain as desired. Readjust if needed.
- Lubrication: The internal mechanisms are factory-lubricated and generally do not require additional lubrication. If unusual noises or stiffness occur, consult a professional.
Troubleshooting
If you encounter issues with your AXA Model 7508 Door Closer, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Door slams shut | Closing speed or end stroke set too fast. | Adjust the closing speed and/or end stroke valves to a slower setting (turn clockwise). |
| Door closes too slowly | Closing speed set too slow. | Adjust the closing speed valve to a faster setting (turn counter-clockwise). |
| Door does not close completely | End stroke not strong enough; door obstruction; incorrect installation. | Increase the end stroke force. Check for physical obstructions. Verify installation according to the template. |
| Door is difficult to open | Opening damping (backcheck) set too high (if applicable). | Reduce the opening damping setting. |
