OPERATION CAUTION: Always hold the tool firmly with one hand on insulation cover and the other on the switch handle. CAUTION: Always press the shoe firmly against the workpiece during operation. If the shoe is removed or held away from the workpiece during operation, strong vibration and/or twisting will be produced, causing the blade to snap dangerously. CAUTION: Always wear gloves to protect your hands from hot flying chips when cutting metal. CAUTION: Be sure to always wear suitable eye protection which conforms with current national standards. CAUTION: Always use a suitable coolant (cutting oil) when cutting metal. Failure to do so will cause premature blade wear. CAUTION: Do not quirk the blade during cutting. Press the shoe firmly against the workpiece. Do not allow the tool to bounce. Bring the recipro saw blade into light contact with the workpiece. First, make a pilot groove using a slower speed. Then use a faster speed to continue cutting. Replacing carbon brushes 1 ► 1 . Limit mark Check the carbon brushes regularly. Replace them when they wear down to the limit mark. Keep the carbon brushes clean and free to slip in the holders. Both carbon brushes should be replaced at the same time. Use only identical carbon brushes. 1. Use a screwdriver to remove the brush holder caps. 2. Take out the worn carbon brushes, insert the new ones and secure the brush holder caps. 1 NOTICE: Do not cut the workpiece with the shoe away from the workpiece or without the shoe. Doing so increases the reaction force which may break the recipro saw blade. ► 1 .
