How do I clear a blockage on my Cordless Blower Vac

Created by Sumec Office, Modified on Tue, 30 Jun at 2:06 PM by Chris McHale

Overview

Blockages in a Cordless Blower Vac can reduce suction, airflow, and overall performance. Most minor blockages can be cleared using the machine’s built-in clearing function without dismantling any components.

Important: Always follow the correct safety procedure and use the designated clearing method only.


Step-by-Step Guide – Clearing a Blockage

Step 1: Put on Protective Equipment

Before starting:

  • Wear protective gloves
  • Wear safety goggles

Important: Never attempt blockage clearing without protective equipment.


Step 2: Prepare the Machine

  • Switch the machine on
  • Set the speed to maximum setting (5)
  • Remove the collection bag from the unit

Important: The machine must be running at full speed for the clearing process to work effectively.


Step 3: Use the Clearing Lever

  • Locate the black lever on the left side of the machine
  • Move the lever back and forth repeatedly
  • Allow airflow to dislodge internal debris

Continue this process until airflow returns to normal.

Important: Do not stop too early—ensure the blockage is fully cleared.


Step 4: Confirm the Blockage Is Cleared

  • Check that suction and airflow have returned to normal
  • Ensure no debris is still restricting the system
  • Reattach the collection bag if required

Important Safety Warning

⚠️ DO NOT ATTEMPT TO REMOVE ANY BLOCKAGES BY HAND

  • Never insert hands or tools into the machine
  • Internal components may move suddenly during operation
  • Always use the built-in clearing lever only

Important: Attempting manual removal may cause injury or damage to the unit.


Frequently Asked Questions

Why does my blower vac keep blocking?

This is usually caused by damp leaves, overfilled collection bags, or debris that is too large for the suction system.


Do I need to switch the machine off before clearing a blockage?

No. The clearing lever function is designed to be used while the machine is running at full speed (setting 5).


Can I use tools to remove the blockage?

No. Only the built-in lever should be used. Using tools may damage internal components.
