The term "power tool" used in the safety instruc- tions refers to mains-operated power tools (with mains cable and mains cable module). Warning! Read all safety instructions and other instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. Keep all safety instructions and other instructions for future refer- ence. Device-specific safety instructions Keep your hands away from the area of the saw and the saw blade. With your other hand, hold the auxiliary handle or the motor housing. If both hands are holding the circular saw, they cannot be injured. Never reach into the area beneath the work- piece. The protective cover offers no protection against injury beneath the workpiece. Adjustthe cutting depth to the thickness ofthe workpiece. Less than the height of one full tooth should be visible beneath the workpiece. Never holdthe workpiece in your hand or across your leg. Secure the workpiece to a stable sur- face. is important to attach the workpiece well to minimise body exposure, the risk of the blade sticking or loss of control. Hold the tool only by its insulated gripping surfaces when performing an operation where the cutting tool may touch hidden wiring or its own cord. Contact with a live wire also makes metallic parts of the power tool live, resulting in an electric shock. When making longitudinal cuts, always use a stop or a straight edge guide. This improves the accuracy of the cut and minimises the risk of the saw blade sticking. Always use saw blades of the correct size and with arbour holes of the corresponding shape (e-g. diamond-shaped or round). Saw blades which do not fit the mounting attachments of the saw will run eccentrically and lead to loss of control. le.

The saw blade washers and bolts were designed especially for your saw to ensure optimum performance and operational safety. Causes and prevention of kickback: Kickback is a sudden reaction to a pinched, bound or misaligned saw blade, causing an uncontrolled saw to jerk up and out of the workpiece towards the operator. Ifthe blade is pinched or bound by the closing kerf, it stalls, and the action of the motor drives the tool back towards the operator. Ifthe saw blade is twisted or misaligned in the cut, the teeth at the back edge of the blade can catch in the surface of the workpiece, causing the blade to spring out of the kerf and back towards the operator. Kickback is the result of misuse of the saw or incorrect operating procedures and conditions. It can be avoided by taking appropriate precau- tions as described below. Grip the saw tightly with both hands and position your arms to resist kickback forces. Always position your body to one side of the blade, never in line with the blade. f kickback occurs, the saw may jump backwards, but kickback forces can be con- trolled by the operator if the appropriate pre- cautions are taken. If the saw blade sticks or you interrupt work, switch the saw off and hold it motionless in the workpiece until the saw blade has come to a standstill. Never try to remove the saw from the workpiece or pull it back while the blade is in motion, as this may trigger kickback. Investigate and take corrective action to eliminate the cause of the saw blade sticking. To restart a saw which is in the workpiece, centre the saw blade in the kerf and check that the saw teeth are not engaged in the material. /f the saw blade is sticking, it may move out of the workpiece or cause kickback when the saw is restarted. Support large panels to reduce the risk of kickback due to a stuck saw blade. Large panels may sag under their own weight. Sup- ports must be placed under the panel on both sides, near the kerf and near the edge of the panel. Never use blunt or damaged saw blades. Saw blades with blunt or misaligned teeth produce a narrow kerf which causes excess friction, sticking of the blade and kickback. Tighten the blade depth and bevel locking levers before making a cut. the settings change during operation, the saw blade may stick and cause kickback. Be particularly careful when performing “plunge cuts” into existing walls or other blind areas. The protruding blade may become stuck in hidden objects and cause kickback. Before using the saw, always check that the lower protective cover closes properly. Do not use the saw if the lower protective cover does not move freely and close instantly. Never clamp or tie the lower pro- tective cover open. ffthe saw is accidentally dropped, the lower protective cover may be bent. Open the protective cover with the retracting handle and make sure that it moves freely and does not touch the saw blade or other parts in any angles or depths of cut. Check the operation of the spring for the lower protective cover. Ifthe lower protec- tive cover and the spring do not work properly, have the saw serviced before using it. Damaged parts, sticky residue or an accumulation of debris may cause the lower protective cover to work sluggishly. Only open the lower protective cover by hand for special cuts such as “plunge cuts and angled cuts." Open the lower protec- tive cover using the retracting handle and release the handle as soon as the saw blade enters the workpiece. For all other cuts, the lower protective cover must function automatically. Make sure that the lower protective cover is covering the saw blade before putting the saw down on the workbench or the floor. An unprotected, coasting saw blade will cause the saw to walk backwards, sawing whatever is in its path. Be aware ofthe time it takes for the blade to stop after the switch is released. 1400HKS-EN / 1106

The riving knife must be thicker than the body of the saw blade but thinner than the tooth width of the saw blade. > Adjust the riving knife as described in the operating instructions. incorrect thickness, positioning and alignment can make the riving knife ineffective in preventing kickback. » Always use the riving knife, except when making plunge cuts. Refit the riving knife after the plunge cut. The riving knife causes interference during plunge cutting and may cause kickback. > Forthe riving knife to be effective, it must be in the kerf. The riving knife is ineffective in preventing kickback during short cuts. » Never operate the saw with a bent riving knife. Even minor interference can slow the closing of the protective cover. » Do not put the saw down vertically on top of the mains cable. This might damage the mains cable. Residual risks: Although the operating manuals or our power tools contain detailed instructions on safe working with power tools, every power tool invoives certain residual risks that cannot be com- pletely prevented through safety. mechanisms Power tools must therefore always be operated with the necessary caution!

Note: To be accurate, an estimation ofthe 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. Specify additional safety measures to protect the operating personnel against the effects of vibra- tion, for example: Maintenance of power tools and accessories, Keeping hands warm, organisation of workflows.

Start-up VAN 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. à f using an extension cable: Only use Before carrying out any work on the machine, pull the main plug. 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 extension cables. Mains cable

I the mains cable is damaged while F% working, pull the mains plug immedi- ately. Connect the mains cable module (9) to the handle The plug must snap in. 1400HKS-EN / 1106 Only use the mains cable module (9) for Kress power tools. Do not attempt to operate other machines with the module. Damaged mains cable modules must not be used. They must be replaced with a new Kress mains cable module immediately. Press the two unlocking buttons (10) and remove the mains cable module (9) from the handle Use only an original Kress mains cable module and at least a heavy rubber tube cable (H05 RN.-F). Operation Saw blade and riving knife (12) must be fited before starting up the saw. Observe the corresponding information in these operating instructions! The riving knife (12) serves as a protection against kickback, and it is thus imperative to fit it! Switching on and off » Before pressing the On/Off switch (1) in the handle, the switch must be unlocked by pressing in the release switch (2). Only then can the saw be put into operation by pressing the On/Off switch For safety reasons, it is not possible to lock the On/Off switch in position for continuous operation. » When the On/Off switch is released, the power supply is interrupted and the saw comes to a standstil. The lock off safety position auto- matically locks the switch and prevents the saw being switched on unintentionally. » The base (14) has been fitted at the factory so that the angle between the base and the saw blade in basic position (zero setting) is pre- cisely 90°. The 4-point mounting guarantees accurate operation. Swing guard » When the saw blade is applied to the work- piece, the swing guard (11), which covers the saw blade, moves back automatically at the same speed at which the blade is applied. When you reach the end ofthe cut, the swing guard moves back under spring pressure to cover the blade again.

Q}y | 773677 à BA Handkreïssäge_1400HKS:book Page 19 Friday, July 22, 2011 11:03 AM Operation English 19 Setting the cut depth » The cutting depth can be set up to 66 mm. > Byreleasing the clamp lever (7)on the housing, the base (14) can be pressed downwards and thus moved in the direction of cutting depth "0." » The cutting depth can be read off on the indi- cator (24) or reset according to the scale. The cutting depth should always match the thick- ness of the workpiece, i.e. the blade should only protrude from the material by approx.the height of 1 saw tooth. This is important in order to prevent accidents! Sawing to layout lines » On the front edge of the circular saw base, there is a marker (indentation) for right-angled cuts (zero setting) corresponding to the saw blade width. There are also marking tongues for 0° and 45° bevel cuts. These enable simple and precise operation. » The marking tongues in the base of the circular saw (see drawing) also correspond to the cut width of the saw blade. When sawing along a layout line, please ensure that you cut according to the left or right edge of the indentation or marking tongue, depending on whether you are sawing to the left or right of the layout line. Changing the tool Fitting the saw blade » Move the motor ofthe circular saw to its highest position (min. cutting depth) — as described under Setting the cutting depth — by releasing the clamp lever (7) and then re-securing the clamp lever (7). » Pull the swing guard (11) back and hold it in end position. » Then fit the individual parts onto the drive spindle of the saw in the following order:

When inserting the blade, make sure that the direction of the arrow on the saw blade corre- sponds to the direction of the arrow on the housing. The bearing surfaces of the saw blade, flange and washer must be clean. » _ Press and hold down the pin for spindle lock (19), and if necessary, rotate the saw blade until the lock snaps into place. > Withthe pin for spindle lock (19) pressed down, tighten the socket-head cylinder bolt (23) with the hex key (13) » To replace the saw blade, carry out the same steps in reverse order. Fit the new blade as described. This kickback safety device must be fitted! » Leave the motor of the circular saw in the same position (min. cutting depth) as was required to fit the saw blade. > Attach the riving knife (12) using the socket- head boit (16) and the washer provided. Atfrst, only tighten the socket-head bolt (16) lightiy. > Adjust the riving knife (12) so that the dis- tance to the tips of the saw teeth and to the lowest point of the saw blade is max. 5 mm {see Figure). The distance to the toothed rim ofthe saw blade must not exceed 5 mm > Fullytighten (10 Nm) the socket-head bolt (16). » The saw is now ready for operation. Operating tips Sawing wood Selection of the appropriate saw blade depends on the type of wood, the quality of the wood and whether longitudinal or transverse cuts are required. When cutting spruce longitudinally, long, spiral shavings are produced. Beech and oak dust are particularly dangerous to health, so always work with a dust extraction system. 1400HKS-EN / 1106 le.

Qi [73e à BA Handkreissäge_1400HKS.book Page 20 Friday, July 22, 2011 11:03 AM 20 English Operation Sawing plastic Sawing plastic, in particular PVC, produces long, spiral-shaped shavings which may be electrostati- cally charged. This can lead to clogging of the sawdust ejector (15) and cause the swing guard cover (11) to jam. We recommend that you use a dust extraction system. Switch the saw on, apply itto the workpiece and carefully begin to saw. Work quickly and without interrupting the cut to prevent the saw teeth sticking. Safety regulations and notes which must be observed > Cracked or distorted blades must not be used. Work only with good, sharp saw blades! » Never use high-alloy HSS blades in this saw. » Saw blades which are not in accordance with the specifications listed in these operating instructions must not be used » Saw blades must not be braked by applying counterpressure from the side after the drive has been switched off » Check that all moving parts ofthe blade guard function correctiy without pinching. » The swing guard must not be locked in open position. » It must be ensured that all devices which cover the blade are functioning properly. » Pullthe plug out of the socket or remove the mains cable module from the handle before replacing the saw blade or performing any servicing work. > Saw blades with a hub thickness greater than the width of the riving knife or a tooth offset width smaller than the width of the riving knife must not be used. » The riving knife must not be removed from the device! It must always be used — except when making insertion cuts > Guide the saw in a straight line without any tilting motion to prevent the saw blade getting jammed in the workpiece. Should the blade become jammed: release the switch immedi- ately! » Never reach under the workpiecel Risk of injury! 1400HKS-EN / 1106 Observe the information in the operating instructions when replacing saw blades. Remove the key from the device after use! Adapt the feed (pressure) to the thickness of the material. Feeding too quickly results in motor overload, increased wear on the saw blade and ragged cuts. The workpiece must be well secured or fixed. The saw blade must reach the maximum max. no-load speed before you begin the cut. Itis essential to ensure that the clamp levers for setting the cutting depth and bevel cuts are properly secured. The workpiece must be checked for foreign bodies. Do not cut through nails! Keep the cable out of the cutting range of the saw! Always route the cable away from the circular saw towards the rear. Never lift the saw off the workpiece until the saw blade has come to a standbstill. Never put your fingers into the sawdust ejector {risk of injury)! The device must always be switched on and off using the trigger switch, never by plugging the device into the mains socket or pulling the plug out of the mains socket or by inserting/ pulling out the mains cable on the circular saw! Wear protective goggles! Wear hearing protec- tion! Wear a dust protection mask! The saw blade diameter must not exceed 190 mm. Observe the specified conditions of use for the saw cutting wood or wood-like materials with saw blades only. Grinding discs must not be used. Do not cut materials containing asbestos! Sockets outdoors must be protected by residual-current circuit breakers (FI-). Never drill into the housing to mark the saw. The protective insulation would be bridged. Use stickers. —#e

The adhesive coating prevents the guide rail from slipping and protects the surface of the work- piece. The coating on the guide rail allows the saw to glide smoothly. To saw at right angles, you can place the saw directly on the guide rail (25). Attach the guide rail (25) using suitable clamping devices, e.g. vices (27) to the workpiece so that the narrow leg of the guide rail (25) points towards the saw blade. The guide rail (25) must not protrude beyond the side of the workpiece which is to be sawn. The guide rail adapter (28) is required for performing bevel cuts with the guide rail (25). The guide rail adapter (28) is fitted as shown in Figure 3. Dust/chip suction Only operate the saw with a functioning dust/chip extractor. The extractor must meet the require- ments of the "Safety regulations for extraction and removal of wood dust and shavings" (ZH1/139). The extractor must ensure a minimum air speed of 20 m/s at the suction neck. Dust from materials such as paints containing lead, some types ofwood, minerals and metal can be health hazards. Contact with or breathing in such dust can trigger allergic reactions and/or breathing problems for the user and other persons in the vicinity. Certain dusts such as oak or beech dust are classed as carcinogenic, especially in combination with wood treatment additives (chromate, wood preservatives) » We recommend the use of a dust extraction device. > Ensure that the workplace is well ventilated. Comply with the relevant regulations in place in your country for the materials to be processed. Use as a bench saw The saw may only be used as a bench saw with saw benches explicitly approved by their manu- facturer for use with this KRESS saw. Special accessories Do not use accessories made by other manufac- turers, as these are not tested by KRESS. Using such accessories can be dangerous. To prevent injury and damage, use only the accessories and parts recommended by KRESS. 1400HKS-EN / 1106 le.
