- Standard Installation (Pull Side):
Mount the door closer body on the door frame and the arm assembly on the door. This is typically used when the door opens towards the closer.

5. Operation and Adjustment
The GOTOTOP door closer features adjustable closing and latching speeds, allowing you to customize the door's closing action for optimal performance and safety.
5.1 Speed Adjustment
Image: A detailed view of the door closer body, highlighting the two adjustment valves. Valve 1 controls the main closing speed, and Valve 2 controls the latching speed.
- Closing Speed (Valve 1): This valve controls the speed of the door from its fully open position until it is about 15 degrees from closing.
- Turn clockwise to decrease speed (slower closing).
- Turn counter-clockwise to increase speed (faster closing).
- Latching Speed (Valve 2): This valve controls the speed of the door for the final 15 degrees of closing, ensuring the door latches properly without slamming.
- Turn clockwise to decrease speed (slower latching).
- Turn counter-clockwise to increase speed (faster latching).
Important: Make small adjustments (quarter turns) at a time and test the door's closing action after each adjustment. Over-tightening or loosening the valves excessively can damage the unit.
5.2 Opening Angle
The door closer allows for an opening angle of 0 to 120 degrees, providing flexibility for various door types and usage scenarios. The adjustable metal rod (0-9cm) also contributes to this flexibility.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your GOTOTOP door closer.
- Cleaning: Wipe the exterior of the door closer with a soft, damp cloth to remove dust and grime. Avoid abrasive cleaners.
- Check Fasteners: Periodically check all mounting screws and arm connections to ensure they are tight. Re-tighten if necessary.
- Lubrication: The internal hydraulic mechanism is sealed and does not require lubrication. Do not attempt to lubricate any part of the internal mechanism.
- Inspect for Damage: Regularly inspect the door closer for any signs of wear, damage, or fluid leaks. If any issues are observed, contact customer support.
7. Troubleshooting
If you encounter issues with your door closer, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
