Using the POWERMAXX 12V BL Cordless Reciprocating Saw is easy. First, make sure the battery is fully charged. You can hold it with one or two hands depending on your comfort and the task. When working in hard - to - reach areas, the saw's light weight and handy design will be very helpful. To adjust the cutting according to different materials, use the Vario (V) - electronics to set the strokes. If you need to work overhead, simply rotate the saw blade 180°. You can also adjust the depth guide without tools for different cutting depths. When using it, always pay attention to the delivery scope and product description as the machine may vary in configuration. Only use the accessories listed in the delivery scope. For maintenance, keep the saw clean after each use. Wipe off any dust or debris. Check the battery regularly and store it in a cool, dry place. If the saw blade gets dull, replace it with a suitable Metabo saw blade from the adapted range.
