Maintenance Tips
-
Clean Regularly: Wipe the rim and mounting area with a soft cloth and mild soap to remove dust and residue; avoid abrasive cleaners that can damage the powder‑coat finish.
-
Inspect Breakaway Mechanism: Check the spring‑loaded positive‑lock breakaway action — clear debris from springs and pivots so the rim returns smoothly after dunking.
-
Tighten Hardware: Periodically check and tighten all bolts and fasteners, especially after heavy use, to keep the goal stable and safe.
-
Net Care: Inspect the Easy‑Glide™ net system and replace a frayed or worn net to maintain consistent ball response and clean ball travel.
-
Protect from Moisture: Keep metal parts dry; if used outdoors, reduce prolonged moisture exposure to slow corrosion and preserve finish.
-
Avoid Excessive Force: Although designed for dunking and rebounds, avoid hanging from the rim beyond normal play to protect springs and bracket integrity.
