Blade clamp sleeve CAUTION: • Always press the shoe firmly against the workpiece during operation. If the shoe is held away from the workpiece during operation, strong vibration and/or twisting will be produced, causing the blade to snap dangerously. • Always wear gloves to protect your hands from hot flying chips when cutting metal. • Be sure to always wear suitable eye protection which conforms with current national standards. • Always use a suitable coolant (cutting oil) when cutting metal. Failure to do so will cause premature blade wear. Press the shoe firmly against the workpiece. Do not allow the tool to bounce. Bring the blade into light contact with the workpiece. First, make a pilot groove using a slower speed. Then use a faster speed to continue cutting. MAINTENANCE CAUTION: • Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance. Replacing carbon brushes 001145 1.
