Switch off, remove plug from mains before adjusting, cleaning or if cable is cut, damaged or entan- gled. Observe correct mains voltage: The voltage of the power source must agree with the voltage specified on the name- plate of the unit. Equipment marked with 230 V can also be connected to 220 V or 240 V. The circuit must at least be protected as follows: AXT 22 D/25 D/23 TC/25 TC/2550 TC= 13 A An extension cable with a cross section that is too small caus- es a distinct reduction in the performance capabilities of the machine. For cables to 25 m in length, a cross section of at least 3 x 1.5 mm

is required, for cables more than 25 m in length, the cross section must be at least 2.5 mm

WARNING! Inadequate extension cables can be dan- gerous. Extension cable, plug and socket must be of watertight construction and intended for outdoor use. Cable connections should be kept dry and off the ground. It is recommended for increased electrical safety to use a Residu- al Current Device (RCD) with a tripping current of not more than 30 mA. Always check your RCD every time you use it. If the supply cord is damaged, it must be replaced by a Bosch Service Centre. When using cable drums, these must be completely unreeled. Products sold in GB only: Your product is fitted with a BS 1363/A approved electric plug with internal fuse (ASTA approved to BS 1362). If the plug is not suitable for your socket outlets, it should be cut off and an appropriate plug fitted in its place by an author- ised customer service agent. The replacement plug should have the same fuse rating as the original plug. The severed plug must be disposed of to avoid a possible shock hazard and should never be inserted into a mains sock- et elsewhere. Assembly Remove the machine from the package. (see figures A–D). Assemble the chute (seefigures E–F) Operation Starting Operation (see figure G) Always place the machine on firm level ground. During operation, do not tilt or move. The motor will coast after switching off! Remove earth from roots. Foreign material such as stones, glass, metals, fabrics or plastics must not enter the chute as- sembly 8. Otherwise this could damage the cutting roller 16. The chute assembly 8 must be empty. Starting Press green button 4. Stopping Press red STOP button 5. Wait for 2 seconds before restarting the machine. Restarting Protection A mains failure causes machine to switch off. The machine cannot restart on its own when the power returns. Return Motion Press and hold the yellow button 6 to reverse the feed. The cutting roller 16 runs backward and frees jammed mate- rial. Overload Protection Overloading (e. g. blocking of the cutting roller 16) causes the machine to stop after a few seconds, that time a beep is audible. Press red STOP button to clear the error. After blocking the tool can start in reverse direction. Press and hold the yellow button 6 to reverse the cutter to un- block. In case of starting in the same direction the tool won’t start and beeps. If the blockage cannot be cleared the pressure plate 15 will need to be moved away from the cutter. The adjustment knob 10 will need to be turned a counter- clockwise direction a small amount until the “jammed” mate- rial is clear. The pressure plate 15 will need adjustment (see “Pressure Plate Adjustment (see figure H)”). Working Advice Wear eye protection, hearing protection and safety gloves at all times while operating the machine. Always check before use that the collection box and chute assembly are fitted correctly. The machine is fitted with sensors, unless the collection box 11 is fitted correctly and the chute assembly 8 is correctly po- sitioned, the machine will not start and the buzzer beeps (on AXT 23 TC/ 25 TC 2550 TC also the 2 LEDs 14 flash). Press the red STOP button to clear the error. Insert the material to be shredded. The material will be fed by the cutter roller 16 without further assistance. Lift back blade cover plate 13. Hook in chute assembly 8 to the garden product, and then release the blade cover plate 13. Press the chute 8 down and turn red clamping knob 9 fully clockwise to lock the chute 8 in place, approxi- mately 5x full turns of the clamping knob 9 are re- quired.

Please keep at safe distance! – Only insert as much material so that the chute assembly 8 will not be blocked up. – Shred withered, moist material and garden waste which has been stored for some days alternately with branches. This prevents the cutting roller 16 from clogging. – Do not fill soft waste such as kitchen rubbish into the shredder but compost directly. – Take care that the shredded material can fall freely from the discharge chute – danger of backing up! – The ventilation slots 3 must not be covered by the shred- ded material. – Avoid blocking the discharge chute with shredded material as this could result in kickback of material through the chute assembly 8 opening. Advice on Shredding Branches become harder to shred depending on the type, age and dryness of the wood. For best results, shred fresh branches soon after they have been cut. Soft garden waste should be shredded in smaller loads, par- ticularly when wet. Any blockages can be avoided by intermit- tently shredding branches. Pressure Plate Adjustment (see figureH) The pressure plate 15 is factory adjusted and may not require adjustment before the first use. Adjustment of the pressure plate 15 is necessary as a result of wear (shredded material, e. g. branches, hangs together as a chain and is not properly cut through). With the motor running in the forward direction (green button 4), turn the adjustment knob 10 a small amount at a time in a clock wise direction until a light grinding sound can be heard (the cutting roller 16 cuts the pressure plate 15 to the proper clearance, and some small aluminium shavings fall out of the ejection chute). To check, look for shavings in the collection box 11. Readjust only to the required extent, otherwise the pressure plate 15 could wear unnecessarily. Troubleshooting The following chart lists problem symptoms, possible causes and corrective action, if your garden product does not operate properly. If these do not identify and correct the problem, contact your service agent. Warning! Switch off, remove plug from mains before adjusting, cleaning or if cable is cut, damaged or entangled.
