YAMAKATO Run/Choke Knob Switch for Predator 3500W — Direct-Fit Durable Replacement

YAMAKATO Run/Choke Knob Switch is a direct-fit replacement knob designed to restore run and choke control on Predator, Powerhorse and Echo Bearcat 3500W inverter generators.

If the original run/choke knob on your 3500W inverter generator has cracked, stripped or stopped holding its position, this YAMAKATO replacement gives you a quick, reliable way to get control back without replacing the entire control panel. Made for the common Predator 3500W platform and compatible Powerhorse and Echo Bearcat equivalents, the knob installs in minutes and uses the included screw to secure it to the metal shaft for a stable connection.

Will this knob fit my Predator 3500W generator?

Yes—the YAMAKATO knob is engineered for the shaft dimensions and mounting style used on Predator 3500W inverter generators and equivalent Powerhorse and Echo Bearcat 3500W models. It is not a universal part and won’t fit 2000W or larger 4500W+ models.

• Compatible models: Predator 3500W, Powerhorse 3500W, Echo Bearcat 3500W
• Not compatible with 2000W or 4500W+ generators
• Direct-fit mounting onto the factory metal shaft
• Includes mounting screw for secure installation

How durable is the replacement knob for frequent use?

The YAMAKATO knob is made from high-quality, wear-resistant materials intended to handle repeated operation and exposure to workshop or outdoor conditions. Its construction resists cracking and deformation so you can rely on consistent performance over time.

• Premium material construction for longevity
• Wear-resistant finish to withstand repeated turning
• Stable performance under typical generator operating conditions
• Resilient to moderate temperature and handling stress

How do I install the YAMAKATO run/choke knob?

Installation is simple: remove the damaged knob, slide the YAMAKATO replacement onto the existing metal shaft, then tighten the included screw to lock it in place. No special tools or modifications are needed—most users finish the swap in a few minutes.

• Remove the old knob from the generator shaft

• Secure with the supplied screw until snug
• Check knob travel and function before use
