General safety instructions for power tools WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference. The term "power tool" in warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool. Work area Tasks or actions which require a lock. Keep work area clean and well lit. Cluttered and dark areas invite to accidents. Recommended by the manufacturer Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite dust or fumes. Further information see Page 26 Illustrated or described accessories are not necessarily included in the scope of delivery Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control. Technical modifications reserved Electrical safety Especially important note for safety. Always follow this note, otherwise it could result in severe injury. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock. Warning of dangerous electrical voltage ST-EN / 0902 Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your EN body is grounded. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock. Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock. Personal safety Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury. Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries. Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents. ST-EN / 0902 If devices are provided for connecting dust extraction and collection facilities, ensure these are connected and properly used. Use of these devices can reduce dust related hazards. Power tool use and care Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed. Do not use the power tool if the switch does not turn on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired. Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tools operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools. Safety rules Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. Use the power tool, accessories and tool bits etc. in accordance with these instructions and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation. Service Have your power tool serviced by a qualified repair person using only original spare parts. This will ensure that the safety of the power tool is maintained. Machine-specific Safety Warnings Keep hands away from the sawing range. Do not reach under the workpiece. Contact with the saw blade can lead to injuries. Apply the machine to the workpiece only when switched on. Otherwise there is danger of kickback when the cutting tool jams in the workpiece. Pay attention that the base plate rests securely on the material while sawing. A jammed saw blade can break or lead to kickback. When the cut is completed, switch off the machine and then pull the saw blade out of the cut only after it has come to a standstill. In this manner you can avoid kickback and can place down the machine securely. Use only sharp, flawless saw blades. Bent or unsharp saw blades can break or cause kickback. Do not brake the saw blade to a stop by applying side pressure after switching off. The saw blade can be damaged, break or cause kickback. English 17 Use suitable detectors to determine if utility lines are hidden in the work area or call the local utility company for assistance. Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to explosion. Penetrating a water line causes property damage or may cause an electric shock. Hold the power tool only by the insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will also make exposed metal parts of the power tool “live” and shock the operator. Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand. Do not work on materials containing asbestos. Asbestos is considered carcinogenic! Take protective measures if there is danger of formation of combustible or explosive dust during operation that can be hazardous to health. Example: Some dusts can be carcinogenic. Wear a dust mask and work with a dust/chip extraction unit, if possible to connect. Always wait until the machine has come to a complete stop before placing it down. The tool insert can jam and lead to loss of control over the power tool. Tools not in use must be locked away safely in a dry place out of the reach of children. Keep your workplace clean. Blends of materials are particularly dangerous. Dust from light alloys can burn or explode. Never use the machine with a damaged cable. Do not touch the damaged cable and pull the mains plug when the cable is damaged while working. Damaged cables increase the risk of an electric shock. Residual risk. Although this information sheet and the operating manuals for our electrical tools contain extensive instructions on safe working with electrical tools, every electrical tool involves ST-EN / 0902 18 English certain residual risks that cannot be completely prevented through safety mechanisms. Therefore, electrical tools must always be operated with the EN necessary caution. Device description

The vibration emission level will vary because of the ways in which a power tool can be used and may increase above the level given in this information sheet. This could lead to underestimation of vibration when the tool is used regularly in such a manner. Note: To be accurate, an estimation of the level of exposure to vibration experienced during a given period of work should also take into account the times when the tool is switched off and when it is running but not actually when doing the job. This may significantly reduce the exposure level over the total working period. ST-EN / 0902

4. Operation

Before carrying out any work on the machine, pull the mains plug.

Putting into operation Observe correct main voltage! Before putting into operation, check that the mains voltage and frequency on the identification plate match the details of your mains supply. Connect mains cable module if necessary If using an extension cable: Only use extension cables specifically approved for the application with the required cross-section. Otherwise the power of the tool can be reduced and the cable can overheat. Replace damaged cables. Mains cable If the mains cable is damaged while working, pull the mains plug immediately. Fixed power supply Fixed power supply Damaged mains cables must not be used. They must be replaced immediately by an expert technician. Mains cable module (500 ST E) Mains cable module with Patent Quick Interlock. Connect the mains cable module 12 to the handle. The plug must snap in. Use the mains cable module 12 only for Kress electric tools. Do not attempt to operate other machines with the module. Damaged mains cable modules must not be used. They must be replaced by a new Kress mains cable module immediately. Push the two unlocking buttons 13 and remove the mains cable module 12 from the handle. ST-EN / 0902 Use only an original Kress mains cable module and at least a heavy rubber tube cable (H07RNF). Operation Switching On and Off Caution! Before switching on the sabre jig saw, the dust cover 3 in front of the tappet must be lowered again to the saw bench 4. To switch on the device, slide the circuit closer/breaker 1 to the front. Pressing the swung-out front edge of the circuit closer/breaker 1 will move it back to the Off position. Restarting protection (500 ST E) The restarting protection feature prevents uncontrolled restarting of the machine after an interruption in the power supply. To restart the operation, switch the On/Off switch 1 to the Off position and start the machine again. Full-wave control electronics (420 ST E) The electronics are switched off by turning the adjusting wheel to the max. position. The jigsaw then operates at the max. idle running stroke rate. Presetting the Stroke Rate In devices with a setting dial 2, you can select the speed using the setting dial 2 depending on the area of application. When under load, the digital electronic control provides for more power. Low stroke rate 1-2: Medium stroke rate 3-4: High stroke rate 5-6: -NOTEAfter longer periods of work at low stroke rate, the machine can heat up considerably. Remove the saw blade from the machine and allow the machine to cool down by running it for approx. 3 minutes at maximum stroke rate. Pendulum stroke setting (500 ST E) Dust extractor The change-over from setting 0 to II is effected by means of the pendulum-stroke adjusting knob 14. The coloured mark indicates the pendulum stroke setting selected. No orbital action for glass, ceramics, soft steel, nonferrous metals, aluminium and pressed materials. The jigsaw is equipped to be connected to a commerically available vacuum cleaner. In order to keep the cut free of shavings, the flexible suction tube is inserted from the back into the housing opening 9. The dust hood 3 is to be pushed downwards until it locks into place. In the case of mitre cuts, the dust hood is to be pushed upwards.

Small orbital action for plastics for plywood.

Large orbital action for hardwood, soft wood, chipboard. It should be noted that the values given are standard values which may vary according to thickness and hardness of material, grain direction, and also to the condition of the saw blade. The optimal orbital action setting for the respective application can be determined through practical testing. The following recommendations apply: Select a lower orbital action setting (or switch it off) for a finer and cleaner cutting edge. For thin materials such as sheet metal, switch the orbital action off. For hard materials such as steel, work with low orbital action. For soft materials and when sawing in the direction of the grain, work with maximum orbital action. Mitre cuts The base plate can be adjusted in both directions by 22.5° and 45°. 0°, 22.5° and 45° angles can be fixed securely. 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. Chip-flyoff guard The splinter guard 10 can prevent fraying of the surface while sawing wood. This application can only be used when cutting at a right angle (90°). Press the splinter guard 10 from below into the base plate 4 shown in the figure). Changing the tool Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures prevent accidental start of the power tool. Wear safety gloves for tool changing. The tool insert can become very hot after working for long periods and/or the cutting edges of the tool insert are sharp. The advantage of the clamping system is that saw blades can be changed without tools. The protection roller, which prevents the saw blade from moving and serves to unburden the mechanical parts (tappet), automatically produces a clamping angle of 90° as a positive stop. Naturally, this only applies when original saw blades are used. Inserting the Saw Blade „B“ First push the dust hood 3 up. Rotate clamping lever 8 as far as it will go and hold in place. Insert saw blade 7 as far as it will go. Release clamping lever 8. -WARNINGPress jigsaw against saw blade tip on wooden board, until clamping lever 8 springs back to its starting position. It is only by doing this that the secure clamping of the saw blade 7 can be ensured and the hood 3 can be closed. ST-EN / 0902 -NOTECheck the tight seating of the saw blade. EN A loose saw blade can fall out and lead to injuries. Unclamping saw blade Rotate clamping lever 8 as far as it will go and hold in place. Remove saw blade 7. -NOTEDo not press back turned clamping levers as this makes it very difficult to remove the saw blade. Operating tips Operation of pendulum jigsaw When sawing, make sure that the base plate is sitting securely on the workpiece. The jigsaw can now be easily operated by hand. To achieve clean cuts and optimal cutting performance, make sure the correct pendulum stroke for the material has been selected on the feed, which should also be adjusted for the material (e.g. pendulum stroke setting 0 and slow feed when sawing metals). The built-in blower keeps the cut continuously free of chips for perfect visibility. Recommended stroke numbers The optimal speed setting is to be determined in tests at the beginning of the sawing job, as several factors such as material, thickness of material, condition of the saw blade, may influence the results of the job. Tools and accessories Cutouts For cutouts, drill a hole i.e. a starting point where the saw can be inserted. Plunge Cutting „A“ Plunge cuts may only be applied to soft materials, such as wood, gypsum plaster boards, etc.! Use only short saw blades for plunge cutting. Plunge cutting is possible only with the mitre angle set at 0°. Place the machine with the front edge of the base plate 4 on to the workpiece without the saw blade 7 touching the workpiece and switch on. For machines with stroke rate control, select the maximum stroke rate. Firmly hold the machine against the workpiece and by tilting the machine, slowly plunge the saw blade into the workpiece. When the base plate 4 fully lays on the workpiece, continue sawing along the desired cutting line.

5. Tools and accessories

Selecting a Saw Blade Only original Kress saw blades as listed in the operating manual or in accordance with the following sketch with a max. thickness of 1.5 mm may be used. This is the only way to guarantee that the saw blade is securely fastened and reduce as far as possible the risk of accidents caused by the jigsaw blades becoming loose. Low stroke number when sawing glass, ceramics, metal. Medium-range stroke number when sawing plastic, pressed material and plywood. The saw blade should not be longer than required for the intended cut. High stroke number when working hardwood, soft wood and chipboard. Use a thin saw blade for narrow curve cuts. Cutting metal When sawing metal, coolant/lubricant should be applied alongside cutting line because of the material heating up. For perfect results with parallel cuts use the graduated parallel fence 11. Once the clamping wheel 6 is loosened, the parallel fence 11 is inserted from the side into the slot in the base plate 4, set according to scale, and fixed with the clamping wheel 6. 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. ST-EN / 0902 Parallel fence (optional accessory) Maintenance and Service Circular cutter (optional accessory) For circular cuts a graduated circular cutter is available (assembly as for parallel fence). The threaded pin of the knobtype handle permits readjustment if a greater downward pressure is required according to material, or if the tip of the threaded pin has been re-ground. Make sure that the counter nut is always well-tightened. Optional Accessory Do not use accessories made by other manufacturers, as these are not tested by KRESS. English 23 Service After heavy use over a long period, the machine should be taken to a EN Kress service location for inspection and thorough cleaning. The relevant service centres are listed in the enclosed appendix "SERVICE" or on the website www.kress-elektrik.de. Spare parts / exploded view It can be dangerous to use such accessories. Exploded views and spare parts lists are available on our home-page http://spareparts.kress-elektrik.de To avoid injury and damage, use only accessories recommended by KRESS.
