Facilità d'uso


-Do not expose resin cutting discs to high humidity or rain! Do not use resin cutting discs past their use-by date (expiration date)! The date (quarter and year) is stamped on the disc’s arbor ring. EXAMPLE: 04 / 2007 This cutting disc can be used through the end of the fourth quarter of 2007, if properly stored and correctly used. Cutting metals IMPORTANT! Always wear approved respiratory protection! Materials that can release toxic substances may be cut only after notifying the proper authorities and under their supervision or that of a person appointed by them. CAUTION! The rapid rotation of the cutting disc heats metal and melts it at the point of contact. Swing the guard as far down as possible (19) in order to direct the stream of sparks forward, away from the operator (fire hazard). -Determine the cut line, mark the cut and apply the disc to the material at moderate speed, to cut a guide groove before going to top speed and applying more pressure to the Power Cut. -Keep the disc straight and vertical. Do not tip it, as this can break it. -The best way to get a good, clean cut is to pull or move the Power Cut back and forth. Do not simply press the disc into the material. -Thick round stock is best cut in stages (20). -Thin tubing and pipes can be cut with a simple downward cut. -Cut large-diameter pipes as for round stock. To prevent tippingand for better control, do not let the disc sink too deeply into the material. Instead, always cut shallow around the whole piece. -Worn discs have a smaller diameter than new discs, so that at the same engine speed they have a lower effective circumfer ential speed and therefore do not cut as well. -Cut I-beams and L-bars in steps; see Figure 21. -Cut bands and plates like pipes: along the wide side with a long cut. -Whencuttingmaterialunderstress(supportedmaterialormaterial in structures), always make a notch in the thrust (pressure) side, and then cut from the tension side, so that the disc does not lock in. Secure cutoff material from falling! CAUTION! If there is a chance that the material is under stress, be pre pared for it to kick back. Make sure you can get out of the way if you have to! Be particularly careful in scrap-metal yards, junkyards, at ac cidentsites,andwithhaphazardpilesofmaterial.Precariously balancedpiecesorpiecesunderstresscanactinunpredictable ways, and may slide, jump out, or burst. Secure cutoff material from falling! Always exercise extreme caution and use only equipment that is in perfect working order. Observe the accident-prevention rules and regulations of your employer and/or insurance organization. Cutting masonry and concrete IMPORTANT! Always wear approved respiratory protection!

Reinforcementrodsmustbecutintheprescribedsequence and in accordance with applicable safety regulations. NOTE: Mortar,stone,andconcretedeveloplargequantitiesofdustduring cutting. To increase the lifetime of the cutting disc (by cooling), to improve visibility, and to avoid excessive dust creation, we strongly recommend wet cutting instead of dry cutting. 19 20 21 10 23 26 25 24 In wet cutting, the disc is wetted at an equal rate on both sides by a trickle of water. MAKITA offers the right accessories for all wet cutting applications (see also "SPECIAL ACCESSORIES"). - Remove foreign objects such as sand, stones and nails found within the working area. Caution: Watch out for electric wires and cables! The rapid rotation of the cutting disc at the point of contact throws fragments out of the cut groove at high speed. For your safety, swing the protection hood down as far as possible (23), so that material fragments are thrown forward, away from the operator. - Mark the cut, and then make a groove about 5 mm (just under 1/5") along the entire length of the planned cut. This groove will then guide the Power Cut accurately guring the actual cutoff. NOTE: For long, straight cuts we recommend using a trolley (24, see also "SPECIAL ACCESSORIES"). This makes it much easier to guide the unit straight. - Perform the cut with a steady back.and.forth motion. - When cutting slabs to size, you need not cut through the entire material thickness (creating unnecessary dust). Instead, simply make a shallow groove, and then knock off the excess material cleanly on a flat surface (25). CAREFUL! When cutting into lengths, cutting through material, making cutouts, etc., always make sure to plan the direction and sequence of cuts in such a way that the disc does not get jammed by the cut.off piece, and that no persons can be injured by falling pieces. Transport and storage - Always turn off the Power Cut when transporting it or moving it from place...
