en ENGLISH 7. Use 7.1 The machine's multifunctional monitoring system If the machine switches off automatically, the machine electronics have activated automatic protection mode. A warning signal sounds (continuous beeping). The beeping stops after a maximum of 30 seconds or when the trigger switch (3) is released. In spite of this protective function, overloading is still possible with certain applications and can result in damage to the machine. Causes and remedies: 1. Battery pack almost flat (the electronics prevent the battery pack from discharging totally and avoid irreparable damage). If one LED (18) is flashing, the battery pack is almost flat. If necessary, press the button (19) and check the LED lamps (18) to see the charge level. If the battery pack is almost flat, it must be recharged. 2. Long continuous overloading of the machine will activate the temperature cut-out. The machine continues to run with reduced performance until the temperature is back to normal. In case of excessive overheating, the machine will switch off completely. Leave the machine or battery pack to cool. Note: If the battery pack feels very warm, the pack will cool more quickly in your "AIR COOLED" charger. Note: The machine will cool more quickly if you operate it at idling speed. 3. If the current is too high (for example, if the machine seizes continuously for long periods), the machine switches off. Switch off the machine at the trigger switch (3). Then continue working as normal (in this case, read in particular the safety instructions in Chapter 4.Kickback. in addition to all other safety instructions). Try to prevent the machine from seizing. 7.2 Switching on and off Switching on: Push the locking button (4) forwards and hold, then actuate the trigger (3) . Switching off: Release the trigger switch (3). 7.3 Working Directions Do not switch the machine on or off while the saw blade is touching the workpiece. Let the saw blade reach its full speed before making a cut. When the hand-held circular saw is added, the movable guard is swung backwards by the workpiece. 14 When sawing, never remove the machine from the material with the saw blade turning. Allow the saw blade to come to a standstill. If the saw blade blocks, turn the machine off immediately. Guide the machine at a speed suitable for the material being processed. Sawing along a straight line: the cutting indicator is used here (9). Sawing along a rail secured on the workpiece: In order to achieve an exact cutting edge, you can attach a rail to the workpiece and then guide the hand-held circular saw by means of the guide plate along this rail. Sawing with parallel guide: For cuts parallel to a straight edge. The parallel guide (10) can be inserted from either side into the support provided for it. Tighten the locking screw (7). It is best to calculate the exact cut width by making a test cut. Sawing with guide rail: For dead straight, tear-free cutting edges with millimetre precision. The anti-slip coating keeps the surface safe and protects the workpiece against scratches. For guide rail, see chapter on Accessories. Battery pack heat generation: Under extremely hard application conditions (e.g. sawing thick wooden planks), the heavy load can cause the battery pack to heat (> 60 °C). To conserve the battery pack, allow it to cool down before continuing work. 8. Maintenance Changing saw blades Remove battery pack from machine. Directly after cutting the saw blade can be very hot - burning hazard! Let a hot saw blade cool down. Risk of injury, even with the blade at standstill. Wear protective gloves when changing blades. Press in the spindle locking button (20) and hold in place. Turn the saw spindle slowly with the spanner in the saw blade fixing screw (21) (16)until the lock catches. Unscrew the saw blade fixing screw in a clockwise direction and remove the outer saw blade flange (22). Pull back the movable guard (26) and remove the saw blade. Ensure that the inner saw blade flange (25) is inserted in the right way: The inner saw blade flange (25) has 2 sides, diameter 20 mm and 5/8" (16 mm). Ensure a precise fit of saw blade mounting hole to the inner saw blade flange (25)! Incorrectly installed saw blades do not run smoothly and lead to loss of control. Insert a new saw blade, Make sure the direction of rotation is correct. The direction of rotation is indicated by arrows on the saw blade and guard.
