-25- Switch on the plunge cut saw (see Chapter 5.2).Plunge to the set cutting depth and slide themachine evenly forward in the direction of thecut. When the cut is completed, switch off the sawby releasing the gearshift lever 8 (Fig. 4). Tilt thesaw unit back into the top locked position.5.7 Sawing with parallel guide fenceWhen making parallel cuts, the parallel guide fence18 (Fig. 1) serves to saw parallel to an alreadyexisting edge. The guide fence can be attached to theleft or right of the machine. The cutting range on theright-hand side amounts to approx. 140 mm (5 ½ in.)and on the left-hand side to approx. 295 mm (11 5/8in.). Once you have unfastened the wing screws youcan adjust the cutting width 19 (Fig. 2) bymoving the guide fence accordingly andafterwards retightening the wing screws.In addition, by simply turning it around (guide face forthe workpiece edge points upwards), the parallel stopcan also be used as double support to improveguidance of the plunge cut saw. Now the machinecan be guided along a lath that is fastened on theworkpiece.5.8 Scoring with the guide rail (specialaccessories)In case of panel materials you canachieve a clean cut if you score.Use a suitable saw blade (seeChapter 4.3).To avoid the surface from tearing out, proceed asfollows: Fasten the guide rail on the workpiece. Tilt the locking lever 20 (Fig. 2) clockwise up tothe limit stop. The scoring depth is now set toapprox. 3 mm (1/8 in.). Place the machine with the guide groove ontothe guide rail. Set the cutting depth - take into account theguide rail thickness (see Chapter 5.3). Score the board. Tilt the locking lever 20 (Fig. 2)counter clockwise up to the limit stop. Plunge to the preset cutting depth and saw thefull board thickness.5.9 Working with the diamond saw blade in fibrecement board (special accessories)Proceed as follows: Use a suitable saw blade (see Chapter 4.3). Exchange the saw blade (see Chapter 4.4).The diamond saw blade wasdeveloped for fibre cement board.The diamond-fitted teeth are moredelicate than the teeth of the HMsaw blade. This is why you areworking with a guide rail.5.10 Working with guide rails To achieve more accurate guidance, set theguide clearance with the two setting wheels 21(Fig.2 and 4).The plunge cut saw can be used to work with theguide rails that are available as special accessories.In addition, it is possible to use some rails that arefreely available on the market. To do so, unscrew the screws and remove theinsert 24 (Fig.2).5.11 Working with the position indicator MT-PAFor pictograms in this regard see page 4.6 Service and maintenanceDangerPull the power plug during allservice work.MAFELL machines are designed to be low inmaintenance.The ball bearings used are greased for life. When themachine has been in operation for a longer period oftime, we recommend to hand the machine in at anauthorised MAFELL customer service shop forinspection.
