[. . . ] This lawn mower is intended for the care of grass and lawns in private gardens. Because of the physical hazard to the operator the lawn mower may not be used: - to trim shrubs, hedges and bushes, - for cutting climbing plants, - for mowing lawns in roof gardens, - for trimming plants in balcony boxes, - for cleaning pavements or other paved areas (vacuuming - blowing away - removing snow), - for shredding and cutting up tree and hedge cuttings - as a tractor device (for self-propelled mowers) - for lawn turning devices, spreading devices, trailers e. Never mow your lawn if persons, particularly children, or animals are in the vicinity. Only start the engine if your hands and feet are at safe distance from the mower deck and blade. [. . . ] Check the machine to make certain that all fasteners, bolts & nuts are tightly fitted; check also for signs of damage or serious wear. Observe the installation instructions when replacing parts - if in doubt always refer to your WOLF Service Centre. Examine the grass box regularly for wear or damage - replace as necessary. Mowers fitted with four-stroke engines must be provided with engine oil before the first start-up (see , , Filling Oil"). Do not refuel or remove the tank filler cap while the engine is running or when the machine is hot. Instead, the machine should be removed from the area where the petrol was spilled. Any attempt to start the mower should be delayed until the fuel vapours have evaporated. If the engine is equipped with a petrol shut-off valve then this be closed after mowing has been completed. Do not leave the mower in closed areas after switching off allow it to cool off in the open air before storing away. Never keep the machine with petrol in the tank within a building in which gasoline vapours may possibly come into contact with naked flames or sparks. Before leaving the mower remove the spark plug lead and - if fitted - the starting key. Never attempt to lift the mower with the engine running - nor with a hot engine - always remove the spark plug lead before lifting or carrying. When folding the mower handlebars, detach starter rope and make certain that the control cables are not snagged or stretched when folding or unfolding. Always carry out the engine oil change with the fuel tank empty and filler cap fitted. The engine should be warmed up prior to draining the oil to ensure all sludge deposits are drained away with the oil. Maintenance and cleaning of the equipment as well as removing the protection device may only be performed with the engine stopped and the spark plug lead and - if available - the starting key, removed. Make certain that all nuts, pins and screws are firmly tightened and that the unit is in a safe operating condition. In order to avoid the risk of fire keep the engine, exhaust, battery box and the area around the fuel tank free of grass, leaves or oil. If the equipment must be tilted for maintenance work then the fuel must be completely drained from the tank beforehand. Clean the equipment after each use with a hand-brush - not with water and do not hose down with a high pressure hose in particular. Make certain to keep the engine cooling fins and engine cooling air intake clean and free from debris. Do not place the equipment in damp areas, near naked flames or where a spark might ignite petrol vapour. [. . . ] Change engine oil more frequently if working under extreme and dusty conditions. To drain the engine oil, remove oil filler cap, tilt machine slowly to side and allow oil to drain from the crankcase through the filler. Disconnect spark plug cap and starter key before proceeding Blade should always be sharpened by an approved Service Centre.
