6 ENGLISHGB SYMBOLS The following symbols can be found on the ma- chine to remind you of the care and attention that are required during use. The symbols mean: Warning! Read the Instruction Book and Safety Manual before using the machine. Warning! Keep onlookers away. Beware of objects being flung out. Warning! Keep hands and feet clear of the cutting deck when the machine is running. Warning! Before starting any repair work, remove the spark plug cable from the spark plugs. IMPORTANT Certain models do not have a throttle control. The engine speed is set for optimal function and mini- mal exhaust emissions. INSTALLATION HANDLE Fold up the lower part of the handle. Then attach the upper part of the handle. This is at- tached with screws, washers and locking wheels (fig. 1). The handle has four different positions. Release the catch with your foot and set the handle in de- sired position (fig. 2). 1. For normal mowing. 2. For mowing under trees, bushes, etc. 3. Parking position. 4. Delivery and storage position. The handle takes up less space if the knobs are released and the handle folded up. CABLE HOLDER Attach the wires to the cable holder (fig. 5). USING THE MOWER BEFORE STARTING FILL THE CRANKCASE WITH OIL The lawnmower is delivered without any oil in the engine crankcase. The crankcase must be filled with oil before the engine is started for the first time. Remove the oil dipstick (fig. 6, 7). Fill the engine’s crankcase with 0.55 litres of good quality oil (service class SE, SF or SG). Use SAE 30 or SAE 10W-30 oil. Slowly fill to ‘FULL/MAX’. Do not overfill. CHECK THE OIL LEVEL Check before using the machine that the oil level is between ‘FULL/MAX’ and ‘ADD/MIN’ on the dipstick (fig. 6, 7). The mower should stand level. Remove and wipe off the dipstick (fig. 6, 7). Slide it down completely and tighten it. Unscrew and pull it up again. Read off the oil level. If the oil lev- el is low, fill with oil up to the ‘FULL/MAX’ mark. FILL UP THE PETROL TANK Fill with petrol before starting the mo- tor. Never remove the filler cap or fill with petrol while the motor is running or still warm. Never completely fill the fuel tank. Al- low a little room for the petrol to expand if necessary. Preferably use environmentally friendly petrol, i.e. alkylate petrol. This type of petrol has a composi- tion that is less harmful to people and nature. It has e.g. no lead additives, no oxygenators (alcohols and ethers), no alkenes and no benzene. NOTE! If you change to environmentally friendly petrol in a motor previously run on ordinary lead- free petrol (95), the petrol manufacturer’s recom- mendations must be followed carefully.
7 ENGLISHGB Ordinary lead-free 95 octane petrol can also be used. You must never use 2-stroke petrol mixed with oil. NOTE! Bear in mind that lead-free petrol is a perishable; do not purchase more petrol than canbeusedwithinthirtydays. STARTING THE ENGINE (Briggs & Stratton) 1. Place the lawn mower on flat, firm ground. Do not start in long grass. 2. Make sure the spark plug cable is connected to the spark plug. 3. If the lawnmower is equipped with throttle con- trol, set the throttle controlBto full throttle (fig. 8). 4. When starting a cold engine: Press down the primer fully 6 times (fig. 9). When starting a warm engine, the primer does not need to be used. If the engine stops due to a lack of fuel, refill and press down the primer 3 times. 5. Press in the Start/Stop loopGtowards the han- dle. NOTE! The Start/Stop loopGmust be kept pressed in to prevent the engine stopping (fig. 8). 6. Grasp the starter handle and start the engine by pulling briskly on the starter cord. 7. For the best cutting results the engine should al- ways be driven at full throttle. Keep hands and feet away from the ro- tating blade. Never put your hand or foot under the blade casing or in the grass ejector while the engine is run- ning. STARTING THE ENGINE (Honda) 1. Place the lawnmower on flat, firm ground. Do not start in long grass. 2. Make sure the spark plug cable is connected to the spark plug. 3. Open the fuel tap (fig. 10). 4. Set the throttle controlBin the choke posi- tion . NOTE! It is not necessary to use the choke position when the engine is warm (fig. 8). 5. Press in the Start/Stop loopGtowards the han- dle. NOTE! The Start/Stop loopGmust be kept pressed in to prevent the engine stopping (fig. 8).6. Grasp the starter handle and start the engine by pulling briskly on the starter cord. 7. When the engine starts, move the throttle con- trol backwards until max. revs are obtained. NOTE! The engine should always be run at maximum revs to avoid abnormal machine vi- brations. Keep hands and feet away from the ro- tating blade. Never put your hand or foot under the blade casing or in the grass ejector while the engine is run- ning. STOPPING THE ENGINE The engine may be very warm immedi- ately after it is shut off. Do not touch the silencer, cylinder or cooling flanges. This can cause burn injuries. 1. Release the Start/Stop-loopGto stop the en- gine. This loop must not be disengaged (e.g. by setting it in the depressed position against the handle), as it will not be possible to stop the en- gine. Honda:Close the fuel tap. 2. If the lawnmower is left unattended, remove the spark plug cable from the spark plug. If the start/stop loop ceases to work, stop theenginebyremovingthesparkplug cable from the spark plug. Immediately take the lawn mower to an authorised workshop for repair. MOWING TIPS Before mowing the lawn, take care to remove any stones, toys and other hard objects. A machine with the MULCHER system cuts the grass, chops it finely and then blows it down into the lawn. The grass clippings need not be collected. The following rules should be observed to give the best MULCHER effect: 1. Use a high engine speed (full throttle). 2. Do not mow when the grass is wet. 3. Do not cut the grass too short. Not more than 1/3rd of the length should be cut off. 4. Ensure that the area under the mower casing is always kept clean.
8 ENGLISHGB 5. Always use a well-sharpened blade. CUTTING HEIGHT Shut off the engine before adjusting the cutting height. Do not set the cutting height so low that the blade/blades come into contact with uneven ground. It is possible to vary the cutting height by moving the wheel axles through four positions (fig. 11). MAINTENANCE No servicing is to be carried out on the engine or mower unit without first switching off the engine and removing the spark plug cable from the spark plug. Stop the engine and remove the spark plug cable if the mower is to be lifted, e.g. during transportation. If the machine needs to be tilted, the fuel tank must be emptied and the engine’s spark plug kept upright. CLEANING After each use the mower should be cleaned. This is particularly important on the underside of the mower casing. Rinse with the garden hose. The mower will then last longer and function better. The paint on the underside of the deck will, in time,bewornawaybythemowingprocess.To prevent corrosion, paint the underside with anti- corrosive paint. Clean the silencer and the surrounding area regularly to remove grass, dirt and flammable waste products. COOLING SYSTEM Before each use, the engine’s cooling system must be cleaned. Clean the cylinder’s cooling flanges and air intake of grass remains, dirt, etc. OIL CHANGE Replace the oil when the engine is warm and the fuel tank is empty. Warm oil runs out of the engine more easily. In or- der to prevent burns, take care while draining as the oil is hot.Change the oil the first time after 5 hours of oper- ation, and subsequently every 50 hours of opera- tion or once a season. Remove the dipstick, tilt the mower and let the oil run out into a container. Be careful not to let any oil run onto the grass. Fill with new oil: Use SAE 30 or SAE 10W-30 oil. The crankcase holds approx. 0.55 litre. Fill until the oil reaches the ‘FULL/MAX’ mark on the dip- stick. Do not overfill. AIR FILTER A dirty and blocked air filter reduces the engine output and increases engine wear. Briggs & Stratton:Carefully remove the air cleaner so that no dirt falls down into the carburettor (fig. 12).Removethefoamfilterandwashitinliquidde- tergent and water. Dry the filter. Pour a little oil on the filter and squeeze it in. Reassemble the air clean- er. Wash the filter every three months or after every 25 hours of use, whichever occurs first. More fre- quently if the engine is used on dusty ground. Honda:Remove the cover and take out the filter. (fig. 13). Carefully check the filter for holes or oth- er damage. A broken or damaged filter must be re- placed. To remove dirt, carefully knock the filter several times against a hard surface or use compressed air from the back of the filter to blow-clean. Do not try to brush the filter clean as this forces dirt down into the fibres. A very dirty filter should be replaced. Clean the air filter after every 25 hours of use or once a season. More frequently if the engine is used on dusty ground. SPARK PLUG Neverremovethesparkplugorspark plug cable when checking to see if there is a spark. Always use an approved test instrument. Clean the spark plug regularly (every 100 hours of operation). Use a wire brush for cleaning. Set the correct spark gap (fig. 14). Change the spark plug if the electrodes are exces- sively burnt or if the plug is damaged. The engine manufacturers’ recommendations are as follows: Briggs & Stratton:Champion J19LM (RJ19LM), spark gap 0.76 mm.
9 ENGLISHGB Honda:BPR6ES (NGK). Spark gap 0.7-0.8 mm. CHANGING BLADES Use protective gloves when changing blades to avoid cutting yourself. Blunt and damaged blades tear up the grass and make the lawn unsightly after mowing. New well- sharpened blades cut off the grass. This gives a green and fresh appearance after mowing. Always check the blades after a collision. First dis- connect the spark plug cable. If the blade system has been damaged, defective parts should be re- placed. Always use genuine spare parts. To replace the blade, slacken the screw. Fit the new blade so that the stamped logo is turned up facing the blade holder (not facing the grass). Re- install as illustrated. Tighten the screw properly. Tightening torque 40 Nm (fig. 15). When replacing the blade, the blade screw should also be replaced. The guarantee does not cover damage to the blade, blade holder or engine caused by running into ob- stacles. When replacing the blade, blade holder and blade screw, always use genuine spare parts. Non-genu- ine spare parts can entail a risk of injury or dam- age, even if they fit the machine. SHARPENING OF THE BLADES Sharpening of the blades must be done by wet method grinding, using a whetstone or a grind- stone. For safety reasons, the blades should not be sharp- ened on an emery wheel. Too high temperature could cause the blade to become brittle. Once the blade has been sharpened, it must then be balanced to avoid vibra- tion damage. STORAGE WINTER STORAGE Empty the fuel tank. Start the engine and let it run until it stops. The same petrol must not remain in the tank for more than one month.Tip up the mower and unscrew the spark plug. Pour a tablespoon of engine oil into the spark plug hole. Pull out the starter handle slowly so that the oil is distributed in the cylinder. Screw in the spark plug. Thoroughly clean the mower and store it indoors in a dry place. SERVICING Genuine spare parts are supplied by service work- shops and by many dealers.
