Cleaning
WARNING: ALWAYS wear protective equipment including eye protection and gloves when
cleaning this tool.
• Keep your tool clean at all times. Dirt and dust will cause internal parts to wear quickly,
and shorten the device’s service life
• Regularly vacuum exposed vents on the tool to prevent the build-up of dust and chippings
within the tool housing
• Clean the body of your machine with a soft brush, or dry cloth
• Never use caustic agents to clean plastic parts. If dry cleaning is not sufficient, a mild
detergent on a damp cloth is recommended
• Water must never come into contact with the tool
• Ensure the tool is thoroughly dry before using it
• If available, use clean, dry, compressed air to blow through the ventilation holes (where
applicable)
Maintaining the track
• Before first use and from time to time as needed, apply a light spray of lubricant so that
the saw will glide smoothly along the length of the track
• Do not allow dust, shavings or other debris to build up on the track

• Excessively worn brushes may cause loss of power, intermittent failure, or visible
sparking
