4. Setup (Installation)
The CISA 604 Series Door Closer can be surface-mounted on left or right-hand doors, for both pull-side and push-side applications. Refer to the included mounting template for precise hole drilling.
4.1. Pre-Installation Steps
- Determine the door's swing direction (left or right) and whether the closer will be mounted on the pull side (hinge side) or push side (opposite hinge side).
- Clean the mounting surface on the door and frame.
- Position the mounting template according to your chosen installation type and mark the drilling points accurately.
4.2. Mounting the Closer Body
- Drill pilot holes at the marked positions.
- Secure the main body of the door closer to the door frame or door using the provided fixing screws. Ensure it is level and firmly attached.

5. Operating Instructions (Adjustments)
The CISA 604 Series Door Closer features independent adjustments for closing speed and final strike, allowing precise control over door movement.
5.1. Adjusting Closing Speed
The closing speed is regulated by a valve located on the side of the closer body. This valve controls the speed of the door from its fully open position until approximately 15 degrees from the closed position.
- To increase closing speed, turn the adjustment screw clockwise (usually marked 'S' or '1').
- To decrease closing speed, turn the adjustment screw counter-clockwise.
5.2. Adjusting Final Strike (Latching Speed)
The final strike, or latching speed, controls the door's speed for the last 15 degrees of closure, ensuring it latches securely without slamming. This is regulated by a separate valve.
- To increase latching speed, turn the adjustment screw clockwise (usually marked 'L' or '2').
- To decrease latching speed, turn the adjustment screw counter-clockwise.
Make small adjustments and test the door's closing action after each adjustment. Avoid over-tightening the screws.

6. Maintenance
The CISA 604 Series Door Closer is designed for minimal maintenance. However, periodic checks can ensure its longevity and optimal performance.
- Annual Inspection: Check all mounting screws for tightness. Re-tighten if necessary.
- Arm Assembly: Inspect the articulated arm for any signs of wear or damage. Ensure all pivot points move freely.
- Cleaning: Wipe the closer body with a soft, damp cloth to remove dust and grime. Avoid abrasive cleaners.
- Functionality Test: Periodically test the door's closing and latching speed to ensure it operates as desired. Readjust if needed.
7. Troubleshooting
