6 ENGLISHGB SAFETY PRECAUTIONS This symbol means WARNING. Failure to follow the instructions carefully may lead to injury or damage. GENERAL • Study the warning stickers on the machine. Re- place any damaged or illegible warning stickers. Read the instructions carefully. Find out what the controls do and learn how to use the machine correctly. Never use the machine if there are people, espe- cially children, or animals nearby. Never let a child or adult use the machine if they are not fa- miliar with these instructions. The user is responsible for any accidents that happen to other people or their property. PREPARATIONS Wear safety gloves, safety goggles and hearing protection. Avoid wearing loose-fitting clothes. Keep a steady stance. Do not lean over the ma- chine. Make sure the machine is on firm, level ground before starting. Do not stand the machine on gravel paths or the like. Objects that are thrown out may bounce and cause damage. Makesurethatallnutsandboltsaresecurely tightened before use. Only use the machine in dry surroundings, never outdoors in the rain. Do not use the machine if it has a faulty safety device or if a guard is missing. OPERATION Avoid starting accidentally. Make sure machine is switched off before plugging it in. Do not feed hard objects, such as stones, bottles, cans or pieces of metal into the machine. They can cause damage to the blades and motor. If the machine is blocked, stop the engine and un- plug from the mains. Remove obstruction and check for damage. Do not jerk the power lead or stretch it tight. Oth- erwise connections or insulation may be dam- aged. Such damage is invisible but dangerous. Always keep the power lead clear of the ma- chine. Remove the plug from the socket and check the lead regularly for signs of damage or ageing. Replace the lead if necessary. Do not use the machine if the power lead is damaged. If the fuse blows or the overload cut-out trips this is a sign that the machine is overloaded, or that too many items are connected to the same supply. Investigate the cause and correct it. Do not fit a larger fuse. Keep your limbs and clothes away from the feed funnel and outlet. Do not stand near the outlet when the machine is running. Keep your face and the rest of your body away from the feed funnel. Never move the machine by dragging the power lead. Stop the motor before moving the machine. Never leave the machine unattended without first switching off and unplugging it. MAINTENANCE AND STORAGE Take care when cleaning or maintaining the ma- chine. The blades will continue to rotate for some time after the motor is switched off. Switch off the motor, unplug the machine and wait until the blades have stopped before inspect- ing the machine or doing any maintenance. If a foreign object strikes the blades or if the ma- chine sounds strange or vibrates excessively, switch the motor off immediately. Unplug the machine and inspect for damage. Repair or re- place damaged components. Tighten any loose components. Do not try to repair the machine if you are not sure how. The manufacturers undertaking and liabilities (according to product liability legislation) apply solely on condition that all spare parts used are approved by the manufacturer or of at least the same quality. Store the machine in a dry place.
7 ENGLISHGB ASSEMBLY LEGS 1. Turn the motor housing upside-down. Insert the screws into the machine from the bottom (fig. 1). 2. The right and left legs differ. Check that the legs are attached so that they are angled outwards (fig. 2). 3. Fix the legs to the machine using washers and nuts (fig. 3). Do not tighten the nuts yet. 4. The axle components are assembled for packing and transportation. Loosen the nuts, wheel bushings and two washers on each side. Insert the axle between the legs (fig. 4). 5. Mount the wheels on the axles using the wash- ers, bushings and nuts (fig. 5). Do not tighten the nuts yet. 6. Turn the machine the right way up and stand it on a level surface. 7. Tighten all the nuts. The legs can be secured by using a spanner to hold each bolt in place from below while tightening the nut (fig. 6). Secure each wheel by holding the one opposite in place with a spanner while tightening the nut on the other (fig. 7). Tighten each wheel approximate- ly the same amount. 8. Snap the hub-caps onto the wheels. (fig. 8). FUNNEL Attach the funnel to the motor housing by hooking it onto the front of the housing then tipping it back- wards. Make sure that the spring in the funnel is in- serted into the hole of the housing (fig. 9). Secure the funnel by tightening the locking knob (fig. 10). OPERATION GENERAL This machine is designed solely for private use, not for professional applications. The compost shredder is designed to shred organic material, such as plant waste, twigs, brush, small branches, etc.The shredder must not be used to mix topsoil. This will destroy the blades. ELECTRICAL SUPPLY Connect the machine to an earthed, single phase electric socket. The circuit must be protected by a 10A slow fuse (fig. 11). Always use an earthed, rubber covered extension lead. Use a high quality lead designed for outdoor use. The conductor area must be at least 3 x 1.5 mm 2. The socket fitted to the lead must be of the water- proof type. We recommend that you use an earth leakage cir- cuit breaker that will cut off the power if anything happens to the machine or the extension lead. If you use a portable earth leakage circuit breaker this must be fitted between the electric socket and the extension lead. The use of an earth leakage circuit breaker does not guarantee your safety. Always follow the safety precautions. We recommend you wear shoes with thick rubber soles. Test the operation of the earth leakage circuit breaker before use. STARTING THE MOTOR The motor will not start until the feed funnel is cor- rectly fitted. Make sure the shredder is empty before you start the motor. Start the motor by pressing the toggle switch to set- ting1(fig. 12). Let the motor reach working speed before you feed anything in. MOTOR CUT - OUT The shredder has a built-in motor cut-out that pre- vents the motor from being overloaded. In the event of overload the toggle switch automat- ically switches to the0setting. The motor can be restarted after leaving it to cool for about 5 minutes. Do not start the motor, set the switch to0, unplug the machine and remove the feed funnel. Clean around the blade disc (fig. 13).
8 ENGLISHGB Replace the feed funnel and restart. NOTE! A safe- ty switch in the motor housing prevents the motor from starting if the feed funnel is not fitted correctly. STOPPING THE MOTOR Stop the motor by pressing the toggle switch to set- ting0(fig. 12). Do not feed in any material after the mo- tor has stopped. It will jam in the ma- chine and may prevent restarting. Unplug the machine before leaving it unattended. SHREDDING The following types of material can be shredded in the shredder: - twigs and branches - waste from pruning bushes - waste from trimming hedges - plant remains and other garden waste that is suitable for shredding To prevent damaging the machine we recommend that you do not exceed the following maximum sizes for twigs and branches: Bio-Master: < 35 mm in diameter Bio-Max: < 40 mm in diameter It is a good idea to place the shredder on a tarpaulin or the like before shredding. This will catch shred- ded material and simplify clearing up. Feed the material you want to shred into the feed funnel. If it is not too bulky it will be drawn in by the blades. A feeder device is supplied with all shredders. The feeder device is used for feeding in small twigs, leafy material and vegetation. Insert the feeder de- vice its full length (fig. 14). Wait until the existing material has been completely shredded before add- ing new material. Shredded material can be shredded a second time to make finer compost. Large branches are best shredded when they are fresh. Garden waste often contains a lot of water which can cause it to stick to the shredder. It is a good idea to let such material dry for a few days before shredding it.Shredded material is ejected and collects beneath the outlet. The pile soon builds up and can block the outlet and stop the machine. Material may even be thrown back out of the feed funnel. Move the shredder or remove the pile of shredded material before this can happen. Reverse or replace the blades regularly. Sharp blades make the work much easier, especially feeding in. Feed in loose shredded material in amounts that the machine can cope with. Do not forcelarge branches against the blades. This overloads the motor and blades unnecessarily. To avoid stoppageslisten to the motor.If the speed drops suddenly pull back the branch and wait until the speed picks up. Feed the branch in gently. If the blades become jammed, read the safety pre- cautions before you open up the machine. Make sure there is no material left in the feed fun- nel when you stop the machine. The blades may jam when the machine is restarted. Store the shredder indoors in a dry place. MAKING COMPOST You can make compost from shredded material in a variety of ways: - Material may be laid in a heap on the ground (cold composting) - Shredded material can be placed in a plastic bin, wooden compost box, mesh container, etc. (cold composting). - Material may be placed in an insulated compost container. This keeps it warm and allows com- posting to continue in the winter. This method gives faster results (warm composting). - Material can be spread straight on the garden (surface composting). MAINTENANCE Always unplug the machine from the electrical supply before carrying out ad- justment or maintenance.
9 ENGLISHGB REPLACING THE BLADES The blades of the shredder have two cutting edges, so they can be reversed. When both edges are worn the blades must be re- placed. Always replace with genuine replacement blades. Replace the blades as follows: 1. Switch off the motor and unplug the shredder. Wait until the blades have stopped. 2. Loosen the locking knob and remove the fun- nel. Always wear safety gloves when clean- ing or replacing the blade disc. 3. Loosen the screws with a screwdriver. There are holes in the blades to simplify this. Inserting the screwdriver through these holes prevents the ro- tary blade from turning (Fig. 15). 4. Reverse the blades and fit them with the sharp edge facing in the direction of rotation. Tighten the screws securely. If both edges of the blades are worn, replace with genuine spare parts or resharpen. SHARPENING BLADES The blades are hardened and therefore must not be ground on an emery wheel. They should only be sharpened wet on a whetstone or carborundum stone. To avoid imbalance the blades must be ground so that each weighs exactly the same. CLEANING Always clean the compost shredder after you have used it. Turn off the motor and remove the plug from the wall socket. Loosen the locking knob and remove the funnel. Clean thoroughly round the rotary blade. Neverusewatertocleantheshredder! Brush off any dirt or plant remains that are stuck to the blades. SERVICE Authorised service agents carry out repairs and service. They use genuine spare parts. Do you do basic repairs yourself? Then make sure you use genuine spare parts.
