en-53 SAFETY INSTRUCTIONS• If the machine starts to vibrate abnormally, check immediately.3.1.5 TRANSPORTING• Ensure that the cutting units are securely fastened in the transport position. Do not transport with cuttingmechanism rotating.• Drive the machine with due consideration of road and surface conditions, inclines and local undulations.• Sudden decelerating or braking can cause the rear wheels to lift.• Remember that the stability of the rear of the machine is reduced as the fuel is used.3.1.6 LEAVING THE DRIVING POSITION• Park the machine on level ground.• Before leaving the driving position, stop the engine and make sure all moving parts are stationary. Applybrakes and disengage all drives. Remove the starter key.3.1.7 SLOPESTAKE EXTRA CARE WHEN WORKING ON SLOPES• Local undulations and sinkage will change the general slope. Avoid ground conditions which can cause themachine to slide.• Keep machine speeds low on slopes and during tight turns.• Sudden decelerating or braking can cause the rear wheels to lift. Remember there is no such thing as a“safe” slope.• Travel on grass slopes requires particular care.DO NOT USE ON SLOPES GREATER THAN 15°IMPORTANT: When working on any slope set the weight transfer, if fitted to its maximum (+) setting.3.1.8 BLOCKED CUTTING CYLINDERS• Stop the engine and make sure all moving parts are stationary.• Apply brakes and disengage all drives.• Release blockages with care. Keep all parts of the body away from the cutting edge. Beware of energy inthe drive which can cause rotation when the blockage is released.• Keep other people away from the cutting units as rotation of one cylinder can cause the others to rotate.3.1.9 ADJUSTMENTS, LUBRICATION AND MAINTENANCE• Stop the engine and make sure all moving parts are stationary.• Apply brakes and disengage all drives.• Read all the appropriate servicing instructions.• Use only the replacement parts supplied by the original manufacturer.• When adjusting the cutting cylinders take care not to get hands and feet trapped when rotating cylinders.• Make sure that other people are not touching any cutting units, as rotation of one cylinder can cause theothers to rotate.• To reduce the fire hazard, keep the engine, silencer and battery compartments free of grass, leaves orexcessive grease.• Replace worn or damaged parts for safety.• When working underneath lifted parts or machines, make sure adequate support Is provided.• Do not dismantle the machine without releasing or restraining forces which can cause parts to movesuddenly.• Do not alter engine speed above maximum quoted in Engine Specification. Do not change the enginegovernor settings or overspeed the engine. Operating the engine at excessive speed may increase the
