Removing Foreign Objects

In order to maintain product performance, be sure to remove any foreign objects and dust from inside the product body, extension pipe or air inlets.

• Foreign materials inside the product can cause the product to be noisy, have poor suction, or shut down during operation.

• If the inside of the product body, extension pipe, inlets, pre-filter, or fine dust filter is clogged with foreign objects, the power will surge (alternating from Hi to Lo power) a few times to alert you to the blocked airflow. The appliance will then automatically turn off to prevent damage. Separate the battery from the product body and remove the foreign objects before resuming use of the appliance.
