[. . . ] Initial operation Before the first operation check that the mains voltage corresponds to that given on the machine nameplate. Motor At the heart of the jigsaw is a powerful universal motor with welded collector which can cope with extended use of the tool. Since it is very important for the motor to be constantly well-ventilated, it is of particular importance to pay special attention to the maintenance and servicing instructions for removing dust and dirt. 2 Clamping and unclamping the saw blades The advantage of the clamping system is that saw blades can be changed without tools. [. . . ] The built-in blower keeps the cut continuously free of shavings for perfect visibility. sheet metal is to be clamped to a suitably solid base (clamping plate or plywood plate). This eliminates as far as possible the risk of the material springing back and forth. Plunge cuts can be made into the material (only when working wood), but should only be attempted by skilled people. The switched-on jigsaw is placed on the work piece at an angle of 55­60° to the front edge of the base plate and pushed down slowly and carefully. Particular care is required at the start of this work; kick-backs and jerks will result if the jigsaw is placed the wrong way, whilst excessively fast plunge cuts may result in broken blades. adjustments are made by loosening the clamping wheel (6) beneath the handle. As soon as the toothed wheel work of the saw bench mounting is released, the base plate (4) can be turned to positions 22. 5° or 45° and be tightened again with the clamping wheel (6). 5 Full-wave control electronics The electronic pendulum jigsaw is equipped with control electronics which can be switched off. The stroke rate can be continuously adopted within a range from 500-2700 strokes per minute to the respective material requirements. adjustment is by means of an electronic-adjusting wheel (2) in the housing. The electronics are switched off by turning the adjusting wheel to the max. The motor can become overheated with longterm heaving loading and low rev. Chip-flyoff guard The synthetic part is placed into the saw opening of the base plate from below (snap fastening). Structure is thereby pressed during sawing against this chip-flyoff guard, thus preventing the wood fibres from being damaged. This application can only be used when cutting at a right angle (90°). dust extractor The jigsaw is equipped to be connected to a commerically available vacuum cleaner. [. . . ] We are therefore able to guarantee free servicing of any production or material faults which arise in the 24 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. The guarantee may only be enforced when defects are reported without undue delay (including shipping damage). [. . . ]
