Cordless vacuum trigger must be held very hard or at a specific angle to keep the unit running

Safety first: Remove the battery before disassembling the handle.

• Inspect trigger movement: Check for sticking, excessive play, or lack of spring return. Clean around the trigger with a dry cloth.
• Open handle housing: Remove screws to access the trigger and switch (if you are comfortable doing so). Note the position of springs and linkages.
• Check switch alignment: Ensure the trigger properly actuates the microswitch. Adjust the trigger position if possible.
• Replace switch or trigger: If the switch is intermittent or the trigger is cracked, replace the trigger assembly or UI board according to parts availability.
• Reassemble carefully: Reinstall all parts and screws securely. Test trigger operation before full reassembly.
