• Seized Motor Shaft:If the coupler has melted onto the shaft due to friction or overheating.

Installation Tips

• Reverse Thread Warning:The coupler is left-hand threaded. Turnclockwiseto loosen andcounter-clockwiseto tighten.
• Tool Usage:Use the included spanner wrench to hold the coupler base steady while rotating the motor shaft, or vice-versa, depending on your model's access point.
• Prying Method:If the old coupler is severely damaged, a flat-head screwdriver can be used to gently pry upward while turning clockwise to break it loose.
• Clean the Shaft:Before installing the new part, ensure the motor shaft threads are clean of old rubber residue or food debris.
• Hand Tighten:Spin the new coupler on by hand; the natural rotation of the motor during use will finish tightening the connection.
