Remove the saw bladeand let the power tool run at the maximum stroke rate foraround three minutes to cool down.Temperature-dependent overload protectionIn normal conditions of use, the power tool cannot be over-loaded. If the power tool is overloaded or not kept within thepermitted battery temperature range, the speed is reducedor the power tool switches off. At reduced speed, the powertool will run again at full speed once the permitted batterytemperature is reached or the load is reduced. If it automat-ically shuts down, switch the power tool off, allow the bat-tery to cool down, then switch the power tool back on.Working AdviceuRemove the battery from the power tool before carry-ing out work on the power tool (e.g. maintenance,changing tool, etc.). The battery should also be re-moved for transport and storage. There is risk of injuryfrom unintentionally pressing the on/off switch.uSwitch the power tool off immediately if the saw bladebecomes blocked.uAlways use a sturdy support when working on small orthin workpieces.Before sawing into wood, chipboard, building materials,etc., check for and remove any foreign objects such as nails,screws, etc.Jigsaws are primarily designed for curved cuts. The range ofproducts from Bosch also includes accessories which enablestraight cuts or circular cuts (depending on the jigsawmodel, e.g. parallel guide, guide rail or circle cutter).Hand-held jigsaws generally tend to go off at an angle, i.e.under certain circumstances the angle and cutting accuracycan no longer be ensured. Decisive influencing factors on theaccuracy are the saw blade thickness, cutting length and thematerial thickness and strength of the workpiece.Therefore, always check using test cuts whether the cuttingresult of the selected system meets the requirements of yourapplication.Plunge cutting (see figureI)uPlunge cuts may only be applied to soft materials,such as wood, gypsum board, etc.For plunge cutting, use only short saw blades. Plunge cuttingis possible only with a mitre angle of 0°.Place the power tool so that the front edge of the base plate(12) rests on the workpiece, without the saw blade (17)touching the workpiece, and switch it on. On power toolswith stroke rate control, select the maximum stroke rate.Press the power tool firmly against the workpiece and allowthe saw blade to plunge slowly into the workpiece.As soon as the base plate (12) rests fully on the workpiece,continue sawing along the required cutting line.Parallel guide with circle cutter (accessory)When working with the parallel guide with circle cutter (26)(accessory), the workpiece must be no more than 30mmthick.Parallel cuts (see figureJ): Loosen the locking screw (25)and slide the scale on the parallel guide through the guide(24) in the base plate. Adjust the desired cutting width as ascale value on the inside edge of the base plate. Retightenthe locking screw (25).Circular cuts (see figureK): Drill a hole large enough to pushthe saw blade through on the cutting line within the circle tobe cut. Machine the drill hole with a router or file so that thesaw blade can lie flush with the cutting line.Position the locking screw (25) on the other side of the par-allel guide. Slide the scale on the parallel guide through theguide (24) into the base plate. Drill a hole in the workpiecein the middle of the section to be cut out. Insert the centringtip (27) through the inner opening of the parallel guide andinto the drilled hole. Adjust the radius as a scale value on theinside edge of the base plate. Retighten the locking screw(25).Coolant/lubricantAs the material heats up along the cutting line when cuttingmetal, you should apply coolant or lubricant.Maintenance and ServiceMaintenance and CleaninguRemove the battery from the power tool before carry-ing out work on the power tool (e.g. maintenance,changing tool, etc.). The battery should also be re-moved for transport and storage. There is risk of injuryfrom unintentionally pressing the on/off switch.uTo ensure safe and efficient operation, always keepthe power tool and the ventilation slots clean.Clean the saw blade receptacle regularly. For this, removethe saw blade from the power tool and lightly tap out thepower tool on a level surface.If the power tool becomes very dirty, this can lead to seriousfaults. For this reason, do not cut materials which generatelarge quantities of dust from below or overhead.If the dust outlet becomes blocked, switch off the powertool, disconnect the dust extraction system and remove thedust and chips.Apply a drop of oil to the guide roller (16) from time to time.Check the guide roller(16) regularly. If worn, it must be re-placed through an authorised Bosch after-sales servicecentre.1 609 92A 7VS | (05.07.2022)Bosch Power Tools
