Subaru / Robin KU3-11071-21 On/Off Switch W/Oil Control

The Subaru/Robin KU3-11071-21 On/Off Switch W/Oil Control provides switching control for applicable lawn tiller electrical circuits, including oil-control functions.

Problems This Part Can Resolve:

• On/off switch gives no electrical response.

• Engine remains active after shutdown.

• Switch feels loose during normal operation.

• Oil-control function responds incorrectly.

• Electrical contact cuts out intermittently.

Switch Fails To Respond

Quick Check: Move the switch through its positions and observe whether the expected electrical response occurs.

Fix Suggestion: Secure the connections or replace the switch if its internal contacts no longer change state.

Prevention Tip: Avoid forcing the switch during normal operation.

Shutdown Function Remains Active

Quick Check: Select the off position and observe whether the engine responds to the command.

Fix Suggestion: Address the related stop circuit or fit a new switch when the internal contact is faulty.

Prevention Tip: Keep the switch wiring supported and free from strain.

Switch Feels Loose

Quick Check: Gently move the switch and look for excessive movement around its mounting point.

Fix Suggestion: Tighten the mounting arrangement or replace the switch if physical wear is present.

Prevention Tip: Protect the control from unnecessary impact.

Oil Control Responds Incorrectly

Quick Check: Observe the oil-control circuit while moving the switch through its applicable positions.

Fix Suggestion: Reconnect loose wiring or renew the switch if its oil-control contact is not working properly.

Prevention Tip: Keep the electrical connections clean and protected.

Customer Experience: After installing the new KU3-11071-21 switch, the on/off control responded properly again. The oil-control function also worked with the switch position as expected, making the controls easier to use.
