PA material rods differ in stiffness based on length and composition; shorter PA rods provide higher rigidity compared to longer PA or PP rods. Usage Instructions 1. Connect poles according to required length. 2. Mount the brush head on the pole. For electric drill usage, attach the hex shaft adapter. 3. Insert the assembly slowly and rotate clockwise. 4. Push and pull back and forth to clear debris. Pulling horizontally may assist in bringing debris out. 5. Wear a dust mask during use. Material Information PA rods supplied fresh may feel rigid. Over time, they absorb ambient moisture and become more elastic. Store in open air to facilitate softening. Do not store sealed in airtight containers. Do not wash with water to protect screw integrity. Safety Precautions Rotate only in a clockwise direction. Reverse rotation may cause internal detachment. Do not apply excessive force if obstruction occurs. If stuck, withdraw slightly while maintaining clockwise rotation before advancing. Limit bending angle to under 30 degrees and reduce rotational speed when bending to prevent structural damage. Note: Please allow for slight measurement variations.
