Fig. 14 Start/Stop Bale Switch 2 Safety Switch Button 1 WARNING The cylinder continues to run for a brief period after the tool has been switched off. Do not tilt or carry the tool while the motor is still running and do not touch the cylinder while it is still rotating. There is a possible danger of injury! 21 OPERATION Overload Protection This product is equipped with overload protection function, and it will be activated in the following circumstances: 1. If the cutting device is wrapped by a build-up of debris. 2. If the material scarified is larger than the motor capacity. 3. Where there is too much resistance against the cutting device. When the circuit breaker has been activated, switch off the product and disconnect it from the power supply. Let the product cool down and clear the problem before restarting. CHANGING THE CYLINDER The tool has two easily exchangeable work cylinders: a dethatcher cylinder made of hard plastic with vertically rotating spring tines, and a scarifier cylinder with vertically mounted high-grade steel knives. WARNING Switch off the tool, remove the battery packs and wait until the cylinder is standing still. WARNING Always wear gloves when handling the cylinder. Turn the tool over. Release the mounting bolt and fold the bearing cover away (Fig. 15). Tilt the cylinder upwards and pull the shaft out of its seat. Pulling the shaft out of its seat may require some force initially. Fig. 15 Mounting Bolt Bearing Cover Scarifier Cylinder 22 OPERATION Install the new cylinder by reversing the sequence (Fig. 16). Ensure that the flattened side of the bearing shell is first inserted in the bearing. Fig. 16 Dethatcher Cylinder USING YOUR TOOL To maintain a well-cared-for lawn it should be dethatched every 4 to 6 weeks. Scarifying with the blade cylinder is a more intensive treatment than dethatching and should only be carried out once a year. The best time is in spring after the lawn has been mown for the first time. How to use your scarifier By scarifying you remove the hardened surface, grass felt, and flat-growing weeds and the crusted over grassroots are loosened up. The lawn will start to breathe again and assimilate nourishing substances such as oxygen and water. This also prevents bacteria from growing in the lawn felt when the grass is dormant. Cut the grass to a height of about 1.57 inch (40 mm) before scarifying. The lawn must be dry when using the tool. The best time for scarifying is any time during the vegetative season, from end of April through to September. Scarify it at least once a year. We recommend using a fertilizer straight after airing if you want a healthy lawn. How to use your dethatcher By dethatching you remove the dead matter, moss, and weed that disfigures a lawn. The build-up of dead grass provides a mat of absorbent fibers which prevents water from getting through to the ground. Do not force your dethacther through grass that is longer than 2.95 inch (75 mm). The lawn must be dry when using the tool. It's recommended that your dethacther be used at the beginning and the end of each grass cutting season to give your lawn a thorough raking. Your dethacther should also be used after each mowing to remove any grass clippings that may be left by your tool. 23 OPERATION WARNING When working on slopes always proceed across the slope. Be particularly careful when walking backwards and pulling the tool. There is a possible danger of stumbling. NOTE: The shorter the grass, the better the lawn can be treated. Furthermore, the load on the tool is less and the service life of the cylinder is prolonged. The tool can be operated with or without the collection bag. Recommendation: Work with the collection bag for dethatching and without the collection bag for scarifying. To ensure that the safety guard flap closes properly, remove any earth that may have collected on the safety guard springs and/or the housing. When working without the bag, check that the safety guard flap is tightly closed. Mow the lawn to the required grass height. Do not use the scarifier in long grass. It may otherwise wind around the scarifier blade and result in damage to the tool. Select the appropriate working or readjustment position (in the event of cylinder wear) so that the tool is not overloaded. Commence work in the vicinity of the power socket and proceed away from the socket. Guide the tool at a walking pace down lanes that are as straight as possible. To ensure uninterrupted scarifying/dethatching the individual lanes should always overlap by 2 to 3 inches. Dwelling too long at the same place while the tool is running can damage the lawn. After work and to transport the tool, remove the battery packs and wait until the cylinder is standing still. Adjust the position to the transport position (0 setting) (see Setting the Working Positions) when transporting the tool. Lift the tool to transport it oversteps and sensitive surfaces (e.g., tiles). Always clean the tool after each use (see Maintenance). After having treated lawns with dense moss growth, it is advisable to reseed the lawn so that it can regenerate itself more quickly. 24 MAINTENANCE WARNING When servicing, use only identical replacement parts. Use of any other parts may create a hazard or cause product damage. Always wear gloves when handling the cylinder. Prior to all maintenance and cleaning work always switch off the tool, remove the battery packs and wait until the cylinder is standing still. GENERAL MAINTENANCE WARNING Do not jet water onto the tool and do not clean it under flowing water. This would result in the danger of an electric shock and the tool could be damaged. WARNING Do not use any attachments or accessories not recommended by the manufacturer of this product. The use of attachments or accessories not recommended can result in serious personal injury. When battery packs are removed and all parts are no longer moving, remove debris adhering to the wheels, inside the ventilation opening, the grass ejector opening and the cylinder.
