User manual KRESS 552 SPS

[. . . ] Operation of pendulum jig saw While sawing, make sure that the base plate is resting firmly on the workpiece. The jig saw can then be easily guided manually. For clean cuts and optimal output, attention should be paid to the correct material-oriented pendulum stroke adjustment and to the likewise material-oriented feed (e. Pendulum stroke adjustment 0 and slow feed when sawing metals). [. . . ] The machines are interference-suppressed in accordance with EN 55014. Initial operation Before the first operation check that the mains voltage corresponds to that given on the machine nameplate. 6 Electronic control The electronic pendulum jig saw is equipped with a disconnectable electronic control system. You can continuously adapt the number of strokes to respective material requirements within a range of 250­2700 strokes per minute. The setting wheel on the handle is used for regulating the number of strokes. This can be done at any time while the machine is in operation. To switch off the electronic control, the setting wheel should be turned to position 6. The jig saw then operates with the maximum no-load number of strokes of 3750/min. The motor can become overheated as a result of sustained heavy loading and low speeds. High speed when working hard-textured wood, soft-textured wood and chipboard. The optimal speed setting should be determined by trials at the beginning of the sawing job, since several factors, such as material, material thickness or state of the saw blade, may influence the working results. Pendulum-stroke setting The change-over between settings 0 to 3 is effected by means of the pendulum-stroke adjusting knob (turning knob). 0 for glass, ceramics, soft steel, non ferrous heavy metal, aluminium and pressed materials Pos. 3 for hard-textured wood, soft-textured wood and chipboard It should be noted that the values stated are standard values which may vary according to thickness and hardness of material and grain direction as well as the state of the saw blade. Parallel fence (optional accessory) For perfect results with parallel cuts use the graduated parallel fence. The parallel fence is inserted from the side through the clamping plate into the slot in the base plate according to the scale and is fixed with the wing bell. Make sure that the counternut is always well tightened. 7 Mounting of clamping device for parallel fence and circular cutter ­ Place the countersunk screw (12) from below into the bore with countersink and tighten with the hexagonal nut (13) (spanner size 7 mm). ­ Mount pressure spring (14) and clamping jaws (15) (the clamp must be correctly positioned so that it is even with the border of the base plate; see detail <x>) and press pressure springs together with the clamping jaw. Screw on the fly nut (16) until the clamping jaw reaches the recess of the base plate (see detail <y>). 8 The synthetic insert is placed from below into the saw opening of the base plate (snap lock). During sawing, the ligneous fibre structure is pressed against this insert, thus preventing the ligneous fibres from being pulled out. [. . . ] Parts which have been replaced become our property.
