When fitting the plug, make sure that the brown (live) wire of this appliance is connected to the plug terminal marked L or coloured red, and the blue (neutral) wire of this appliance is connected to the plug terminal marked N or coloured black. Under no circumstances must the wires of this appliance be connected to the earth terminal of the plug marked either E, with the earth symbol or coloured green or green/yellow. Brief description The sawdust blower removes sawdust ahead of the cut ­ very practical when sawing along a line. The stroke-rate (= movements per minute of the saw blade) can be infinitely varied by means of the adjustment wheel.(not for ST 400, ST 440) B The on-off switch is shaped in such a way that it can be used from the forward or the rear holding position. The on-off switch can be fixed in the "On"- position for continuous operation by means of the locking button. Integrated suction channel for connection to a vacuum-cleaner. 15 0 The anti-splintering device almost entirely prevents the edge of the wood from splintering. (Accessory*) The base plate can be tilted to both sides by 45o for bevel cuts. The vibration damper permits quieter running by means of a counterweight on the plunger. 2 ENGLISH A Transparent cover for optimum sawdust removal. II I II I 0 Integrated tool storage for spare blade. The built-in pendulum stroke improves the cutting performance. The pendulum stroke of the saw blade means it is only pressed against the material on the reverse stroke (working stroke) and lifted off the material on the forward stroke. Result: better extraction of sawdust, lower friction ­> higher cutting performance. The pendulum stroke can be adjusted by the pendulum stroke control and thus adapted to different kinds of material. (not for ST 400, ST 440) Modifications: Text, diagrams and data are correct at the time of printing. In the interest of continuous improvement of our products, technical specifications are subject to alteration without prior notice. ST 400, ST 440, STEP 420, STEP 450, SPE 70, SPE 80 A Inserting the saw-blade Always disconnect the plug from the socket before carrying out any work on the machine. 0 1. Slide the transparent cover downwards, then the clamping screw is more accessible. 2. Loosen the clamping screw about 2 revolutions by means of the hexagonal allen key (fitted into the base plate). 3. Fit the saw blade into the groove of the support roller and push it firmly into the plunger as far as it will go; the lug of the saw blade must contact the end of the plunger (see illustration). 4. Retighten the clamping screw. 5. Check that the saw blade is sitting firmly (wear protective gloves!). Adjusting the base plate The base plate can be tilted or moved backward or forward. 274315 Setting an angle For angle cuts and bevels. Loosen the fixing screw, pull the base plate out of the mounting, set it at the required angle (15o, 30o, 45o), push it back into the mounting and tighten the fixing screw again. Angles other than 45o can be set by not pushing the base plate back into the mounting. The angle can be read off the scale. For very exact angle cuts it is recommended to make a test cut. Moving the base plate For plunge cuts or cuts in corners. Loosen the fixing screw, push the base plate to the rear and tighten the fixing screw again. The base plate in this position is fixed at the 0o setting. Moving back For cutting a hole with a short saw blade and sawing near the edge. Take the fixing screw out, push the base plate to the rear and screw the fixing screw tightly into the rear hole. In this position the base plate can also be off-set in longitudinal direction.

The stroke rate can be set on the stroke rate control even while the motor is running. Sawdust removal Only operate the machine with suitable sawdust removal. The integrated suction channel has the standardized internal diameter of 30 mm. Use the suction hose (Id. No. 4932 3304 12) from our range of accessories to connect it to a household vacuum cleaner or to an wet-and-dry vacuum cleaner. 1. Push in and turn the suction hose into the suction channel until it fits firmly. 2. Push the transparent cover downwards to ensure optimum sawdust removal. 15 0 15 0 ENGLISH 4 ST 400, ST 440, STEP 420, STEP 450, SPE 70, SPE 80 A B A Adjusting the stroke rate (only applicable for STEP 420 STEP 450 SPE 70 SPE 80 A) The stroke-rate (= movements per minute of the saw blade) can be infinitely varied by means of the adjustment wheel. The letters A to G are printed on the speed control, meaning: A = lowest stroke rate G = highest stroke rate II I II I 0 II I II I 0 Advice for operation 1. Set the stroke and pendulum stroke according to the material to be cut. 2. Position the machine with the front part of the base plate on the material, and switch on. 3. Press the machine downwards onto the material and guide it along the cutting line. Hints Do not press down too hard on the piece you are cutting. Light pressure on the saw blade is sufficient to achieve the optimum rate of sawing. When cutting along a score line, use the marking on the anti-splintering device as an optical guide. To obtain a perfectly straight cut, clamp a strip of wood as a guide along the material or use the parallel guide (accessory). For cutting at an angle, or cutting a bevel, adjust the base plate. For sawing close to the edge, set the base plate at its rearmost position. To avoid vibration, clamp metal sheets onto a wooden base. To saw metal, use cooling agents along the cutting line (oil, white spirit). Plunge cuts without pre-drilling a hole are possible with soft materials (wood, light building materials for walls). Harder materials (metals) must first be drilled with a hole corresponding to the size of the saw blade. Move the base plate to the rearmost setting in order to obtain the best possible cutting angle for starting the cut.(see section "Adjusting the base plate") Sawing sheet metal Plunge cuts 1. Set the pendulum stroke at the pendulum stroke control to "0". 2. Without switching the machine on, place it with the front edge of the base plate on the cutting point. 3. Switch the machine on and carefully lower the saw blade already running into the material.
