4. Setup & Installation
The Hager 5300 Series door closer offers versatile multi-mount installation options, including parallel arm, regular arm, and top jamb configurations. The installation type is screw-in. Refer to the specific template provided with your closer for precise hole drilling and mounting instructions.
4.1. General Installation Steps
- Prepare the Door and Frame: Ensure the mounting surfaces are clean, flat, and reinforced if necessary.
- Select Mounting Position: Determine the appropriate mounting configuration (regular, parallel, or top jamb) based on door swing and desired appearance.
- Mark Drill Holes: Use the provided template to accurately mark the locations for drilling pilot holes on the door and frame.
- Drill Pilot Holes: Drill pilot holes to the recommended depth and diameter for the mounting screws.
- Mount the Closer Body: Secure the door closer body to the door or frame using the provided screws.
- Install the Arm Assembly: Attach the main arm to the closer spindle and the forearm to the frame or door bracket, depending on the chosen configuration. Ensure all connections are tight.
- Initial Adjustment: Perform initial adjustments as described in Section 5 to ensure the door closes smoothly and latches correctly.

5. Operation & Adjustment
The Hager 5300 Series door closer features adjustable spring sizes from 2 to 6, allowing for customization to various door weights and sizes. Adjustment valves are staked to prevent accidental removal, ensuring consistent performance.
5.1. Spring Power Adjustment
The spring power determines the closing force of the door. To adjust:
- Locate the spring adjustment nut on the end of the closer body.
- Turn the nut clockwise to increase closing force (for heavier doors or higher wind conditions).
- Turn the nut counter-clockwise to decrease closing force (for lighter doors or easier opening).
- Caution: Do not over-tighten or loosen the spring adjustment nut beyond recommended limits. Refer to the closer body markings for safe adjustment range.
5.2. Closing Speed Adjustment
The door closer typically has two or three adjustment valves to control different phases of the closing cycle:
- Main Closing Speed Valve: Controls the speed of the door from its fully open position to approximately 10-15 degrees from closed.
- Latching Speed Valve: Controls the speed of the door for the final 10-15 degrees of closing, ensuring the door latches securely.
- Backcheck Valve (if present): Provides hydraulic resistance when the door is opened forcefully beyond a certain point, protecting the door and frame.
To adjust any valve, turn it clockwise to decrease speed (slower closing) or counter-clockwise to increase speed (faster closing). Make small adjustments (quarter turns) and test the door's operation after each adjustment.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Hager 5300 Series door closer. The tempered springs, made of double heat-treated steel, contribute to its durability.
- Periodic Inspection: Annually inspect the door closer for any signs of wear, damage, or loose fasteners. Check the arm assembly, mounting screws, and closer body.
- Cleaning: Wipe down the closer body and arm with a soft, damp cloth to remove dust and grime. Avoid abrasive cleaners or solvents.
- Lubrication: The internal components are factory-lubricated and sealed. No additional lubrication is typically required. If the arm pivots squeak, a small amount of silicone-based lubricant can be applied to the pivot points.
- Re-adjustment: If the door's closing speed or force changes over time, re-adjust the valves as described in Section 5.
- Tighten Fasteners: Periodically check and tighten all mounting screws and arm assembly fasteners to ensure they are secure.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Door slams shut | Closing speed or latching speed set too fast. | Turn the main closing speed and/or latching speed valves clockwise (slower). |
| Door closes too slowly or doesn't latch | Closing speed or latching speed set too slow; insufficient spring power. | Turn the main closing speed and/or latching speed valves counter-clockwise (faster). Increase spring power if necessary. |
| Door is hard to open | Spring power set too high. | Decrease spring power by turning the spring adjustment nut counter-clockwise. |
| Oil leakage | Damaged seals; closer body cracked. | Contact Hager support. The closer may need replacement. |
| Door closer noisy | Loose fasteners; worn arm components. | Check and tighten all mounting screws and arm connections. Lubricate arm pivots if needed. |
