Parkside Worn Trigger Mechanism / Microswitch Misalignment

Vacuum trigger must be held very hard to keep unit running

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Worn plastic trigger cam in Parkside handle, Misaligned microswitch, Weak trigger return spring, Cracked trigger pivot

Safety: Remove the battery before disassembling the handle.

Open handle: Remove screws and separate the handle halves to access the trigger mechanism.
Inspect trigger: Check for cracks, wear on the cam surface, or broken pivot points. Replace the trigger if damaged.
Check switch alignment: Ensure the trigger fully depresses the microswitch. Adjust position if possible or replace the switch if its actuator is worn.
Lubricate lightly: Apply a tiny amount of plastic‑safe lubricant to the trigger pivot if it binds.
