Using this Metabo metal chop saw is straightforward. First, make sure it's connected to a proper single-phase alternating current power source. When cutting profiles, pipes, or rods of steel, cast iron, aluminum, or other non - ferrous metals, adjust the quick clamping device according to your desired mitre angle between -15° and 45°. If you need to change the cutting disc, use the spindle lock to make the process easier. For safety, always keep the swiveling cutting guard in place and adjust the spark guide plate. Also, set the cutting depth limiter as per your requirements. When it comes to maintenance, store the double - ended wrench in the provided storage on the machine table. Regularly check the motor and gear with ball bearings for any signs of wear. And don't forget to clean the saw after each use to keep it in good working condition.
