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

Safety first: Remove the battery before opening the handle.

• Inspect trigger movement: Check for excessive play or stiffness in the trigger. If it wobbles or feels loose, internal parts may be worn.
• Open handle (advanced): Remove screws and separate the handle housing. Observe how the trigger presses the microswitch.
• Realign or replace parts: If the trigger no longer fully depresses the switch, adjust its position or replace the trigger lever. If the microswitch is worn (no distinct click), replace it or the entire handle PCB assembly.
• Reassemble and test: Ensure the trigger operates smoothly and reliably after reassembly.
