User manual KRESS 552 SPS

[. . . ] Sheet metal should be clamped on an adequately firm base (chipboard or plywood) to prevent any resiliency of the material. 3 Cutouts/Pocket cuts For cutouts , drill a hole as a starting point for the saw. Plunge cuts into the material (only when working with wood) are possible, but should be attempted only by skilled hands. The jig saw is switched on and placed on the work at an angle of 55­60° to front edge of base plate and is then slowly and carefully pushed down. [. . . ] The setting wheel on the handle is used for regulating the number of strokes. 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. 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. This method can only be applied when cutting with an angle of 90°. Replacing carbon brushes Our service personnel will carry out this and all other servicing work quickly and professionally. Always keep the openings required for cooling the motor free of dust and dirt. The movable supporting roller for the saw blade should be provided regularly with a drop of oil. As far as the rest of the machine is concerned, the jig saw requires hardly any service. All moving parts are adequately lubricated before leaving the factory. [. . . ] This electrical tool has been designed with high precision and was approved after undergoing strict quality control checks in the factory. We are therefore able to guarantee free servicing of any production or material faults which arise in the 6 months after the date of sale to the purchaser. We reserve the right to repair defective parts or else replace them with new parts. The guarantee will be rendered void if the device is used improperly, mistreated or opened up by unauthorised repair personnel. [. . . ]
