J Dust that arises when working on material containing asbestos or stonework containing crystalline silicic acid is harmful to the health. Please follow accident prevention regulations. J Appliances used at many different locations including open air must be connected via a current surge preventing switch. J Always use the protective shields on the machine. J Always disconnect the plug from the socket before carrying out any work on the machine. J Always wear goggles when using the machine. It is recommended to wear gloves, sturdy non slipping shoes and apron. J Sawdust and splinters must not be removed while the machine is running. J Do not pierce the motor housing as this could damage the double insulation (use adhesives). J Keep mains lead clear from working range of the machine. Always lead the cable away behind you. J Only plug-in when machine is switched off. J Dust that arises when working on wood or using the tool on industrial material can be dangerous to health. In this case connect the tool to a suitable suction device. J Do not use cracked or distorted saw blades. Advice for your safety Typically the A-weighted sound pressure level of the tool is 82 dB (A).The noise level when working can exceed 85 dB (A). Wear ear protectors! Measured values determined according to EN 50 144. Measured sound value Typically the weighted acceleration is 3 m/s2. Measured values determined according to EN 50 144. Measured vibration value This jig saw can cut wood, plastic and metal; it can cut straight lines, bevels, curves, and internal cut-outs. Do not use this product in another way as stated for normal use. Use ENGLISH p. 45

Connect only to a single-phase AC current supply and only to the mains voltage specified on the rating plate. Connection to sockets without earth protection is possible as the appliance features protective insulation to DIN 57 740/ VDE 0740 and CEE 20. Radio suppression complies with the European standard EN 55014. Mains connection 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 on-off switch is shaped in such a way that it can be used from the forward or the rear holding position. The sawdust blower removes sawdust ahead of the cut – very practical when sawing along a line. The on-off switch can be fixed in the ”On”- position for continuous operation by means of the locking button. 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)

Transparent cover for optimum sawdust removal. Integrated suction channel for connection to a vacuum-cleaner. III II

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. ENGLISH

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. Inserting the saw-blade

Always disconnect the plug from the socket before carrying out any work on the machine.

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.

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.

Continuous use Switching on: Press the On-/off switch and then the locking button, after that release on-off switch. Switching off: Press the On-/off switch and then release.

Intermittent use Switching on: Press On-/off switch Switching off: Release On-/off switch

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

The stroke rate appropriate to the material being worked on can be taken from the following table, and the corresponding letter shown on the setting wheel. Material Stroke rate Wood Steel Aluminium Rubber

The stroke rate shown in the chart is only a suggestion for your general guidance! The stroke rate can be set on the stroke rate control even while the motor is running. 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.

Only operate the machine with suitable sawdust removal.

1. Push in and turn the suction hose into the

suction channel until it fits firmly.

2. Push the transparent cover downwards to

1. Set the stroke and pendulum stroke according to the material to be cut.

Advice for operation

2. Position the machine with the front part of the base plate on the material, and

3. Press the machine downwards onto the material and guide it along the cutting line.

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. Hints 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 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”)

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

3. Switch the machine on and carefully lower the saw blade already running into the

STEP elec 50 tronic 0 material. Anti–splintering device (Accessory*) The anti-splintering device almost entirely prevents the edge of the wood from splintering. Place the anti-splintering device as shown in the illustration with the smooth side downwards and flush with the base plate (this is only possible with the base plate in the forward position). *Not included in standard equipment, available as an accessory. ENGLISH

Parallel guide and circle cutting guide (Accessory*) Using the parallel guide or circle cutting, parallel cuts of 0–200 mm, circular cuts of 100–400 mm are possible. Use cross-cut saw blades. *Not included in standard equipment, available as an accessory. Push the parallel guide, with the contact surface facing downwards, through the lugs in the base plate and fasten it in position with the capstand–headed screw. Assembly of parallel guide

For cutting from the left or from the right, push the parallel guide in from the appropriate side. GERMANY Push the parallel guide, with the contact surface facing upwards, through the lugs in the base plate and fasten it in position with the capstand–headed screw. Cutting a circle

Tighten the centre point into the parallel guide from the top. GERMANY Ensure that the saw blade and the circle centre point form one single line. When working on delicate surfaces please use the plastic protection shoe. Plastic protection shoe (Accessory*)

Fit the plastic protection shoe to the front of the base plate (as illustrated) and fix the lugs with the back of the base plate. Assembly

*Not included in standard equipment, available as an accessory. GERMANY Bend up both lugs and remove the plastic protection shoe.
