MAINTENANCE
CLEANING AND STORING
Carbon Brushes
When the carbon brushes wear out, the rotary tool will spark and/
or stop. Carbon brushes are a wearing component of the rotary
tool therefore not covered under warranty.
Continuing to use the rotary tool when
carbon brushes need to be replaced
may cause permanent damage to the
rotary tool. Carbon brushes will wear
out after much use. When they need to
be replaced, be sure to take the rotary tool
to an electrician or a power tool repairer. Replace
both carbon brushes at the same time or contact Populo customer
service if you have any servicing questions.
Accessories
All accessories can be kept in the plastic accessory
container for convenient storage or transport.

Possible Cause
Remedy
Keep the vents of the rotary tool clean at all times. If
possible, prevent foreign matter from entering the vents. After
each use, blow air through the rotary tool housing to ensure it
is free from all dust particles which may build up. Build up of
dust particles may cause the rotary tool to overheat and fail. If
the enclosure of the rotary tool requires cleaning, do not use
solvents but a moist soft cloth only. Never let any liquid get
inside the rotary tool. Never immerse any part of the rotary
tool into a liquid. If the supply cord is damaged, it must be
replaced by the manufacturer, its service agent or similarly
qualified persons to prevent any potential hazard.
