[. . . ] Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool. B) Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. unmodified plugs and matching outlets will reduce risk of electric shock.

For lower voltage and models for specific countries, these values can vary. Selecting a Saw Blade An overview of recommended saw blades can be found at the end of these instructions. Use only T-shank saw blades or saw blades with 1/4" universal shank (U-shank). The saw blade should not be longer than required for the intended cut. Inserting the Saw Blade (see figure A1) Clean the shank of the saw blade before inserting it. Insert the saw blade 10 (teeth in cutting direction) to the stop into the saw blade holder. While inserting the saw blade, pay attention that the back of the saw blade is positioned in the groove of the guide roller 9. PST 670 L: Precise cuts are only possible when the guide roller 9 faces closely but not too tight against the back of the saw blade (the saw blade 10 may not be bent by the guide roller). If required, loosen screw 23 and move the holder 22 of the guide roller in such a manner that the guide roller faces closely against the back of the saw blade. For this, push the dust cover together at the two outer holders and pull it off toward the front. An overview for the connection of various vacuum cleaners can be found at the end of these instructions. Switch the saw dust blower off when a dust extraction system is connected (see "Sawdust Blower Device"). Inserting/Replacing the Laser Module Batteries Insert the supplied batteries 15 into the laser module 14 before starting operation for the first time. Pay attention to the correct polarity according to the representation on the battery lid. Use only LR44 batteries from the same manufacturer and with the same capacity. Attaching/Removing the Laser Module Insert the laser module 14 with the inside noses engaging into the notches on the casing of the power tool and push it down to the stop. To remove the laser module, push it upward and remove it from the casing. The laser module must be removed from the power tool when used for stationary work or when sawing from below a workpiece. One can easily be blinded from the laser beam when carrying out such work. The splinter guard 21 (accessory) can prevent fraying of the surface while sawing wood. The splinter guard can only be used for certain saw blade types and only for cutting angles of 0°. [. . . ] Circular Cuts (see figure J): Set the locking screw 27 to the other side of the parallel guide. Slide the scale of the parallel guide through the lead 26 in the base plate. Insert the centring tip 29 through the inside opening of the parallel guide and into the drilled hole. Coolant/Lubricant When sawing metal, coolant/lubricant should be applied alongside cutting line because of the material heating up. [. . . ]
