No. Commercial door closers are complex mechanisms, and improper adjustments can lead to more bigger, more expensive problems, including the following:
Potential for Damage: Commercial door closers are calibrated for specific door sizes and weights. Making adjustments without proper knowledge can put undue stress on the closer's internal components, leading to damage and potential failure.
Safety Hazards: A malfunctioning door closer can compromise fire safety by not closing the door properly. Incorrect adjustments can also create a slamming hazard, posing a risk to employees and customers.
Warranty Considerations: Most commercial door closers come with warranties. Attempting DIY repairs or adjustments can void the warranty, leaving you responsible for any resulting repairs or replacements.
