Yonex Astrox 77 Play Badminton Racket

• Store in the full-length cover, in a cool dry place — never in a car boot/dashboard or direct sun (heat softens and warps carbon frames).

• Never string above the printed maximum tension — over-tension voids the manufacturer warranty and risks frame collapse.

• Restring every 3–6 months if you play regularly. Rule of thumb: restring as many times per year as you play per week.

• Check grommets at every restring; replace worn or cracked ones — Prime Sports does this during our free stringing service.

• Replace the grip when it loses tack or absorbency; a fresh overgrip protects the handle and your control.

• Avoid racket clashes in doubles and scraping the floor for low shots — the most common cause of cracks.

• Wipe frame and strings with a soft dry cloth after play; never use solvents or chemical cleaners.

• Coastal humidity tip: keep a silica gel pouch in your kit bag during monsoon months.

• Any manufacturing defect? Bring the racket and bill to Prime Sports — manufacturer warranty claims handled by us.
