Adjustment Points:

  • Speed Regulation Valve: Controls the speed of the door's sweep motion (the main closing phase). Turn clockwise to decrease speed, counter-clockwise to increase speed.
  • Latch Regulation Valve: Controls the speed of the door's final closing phase (latching action). Turn clockwise to decrease speed, counter-clockwise to increase speed.
  • Backcheck Control Valve: Controls how far the door opens and provides cushioning to prevent the door from being forced open too wide. Adjust to prevent damage to the door or frame.
  • Hold-Open Function: The hold-open mechanism can be engaged or disengaged by adjusting the nut on the connecting arm. Turn counter-clockwise to engage or adjust the hold-open angle.

Important: Make small adjustments (quarter turns) and test the door's operation after each adjustment. Over-adjusting can damage the closer or cause improper function.

6. Maintenance

Regular maintenance ensures optimal performance and longevity of your FORTSTRONG door closer.

  • Cleaning: Periodically wipe down the closer body and arm with a soft, damp cloth to remove dust and debris. Avoid abrasive cleaners.
  • Fastener Check: Annually inspect all mounting screws and fasteners to ensure they are tight. Re-tighten if necessary, but do not overtighten.
  • Fluid Leaks: Check for any signs of hydraulic fluid leaks around the closer body. If leaks are detected, contact customer support.
  • Smooth Operation: Observe the door's closing action. If it becomes erratic, too fast, or too slow, refer to the adjustment instructions.
