Product description

The IBF 31-4 petrol brushcutter from IKRA comes with an undergrowth cutter and a cutting line spool. The cutting line spool can be used to conveniently trim grass and non-woody plants, e.g. grass tufts at lawn edges or under fixed objects, such as benches or tables. The robust nylon cutting line is 2.4 mm thick. A cutting line cartridge with the designation DA-F16 is already included with the delivery. The three-blade cutting disc can be used to easily cut through undergrowth with thicker stalks, tall grass and woody weeds. If the cutter has become blunt over the course of time, it can be turned over in order to extend the service life of the cutter. Changing between spool and cutter is very simple. The cutting line produces a cutting width of 43 cm and with the blade cutter a cutting width of 25.5 cm.

The powerful, high-performance 4-stroke engine, with 31 cc capacity and 0.7 kW, is quieter running and is easier to handle in comparison to conventional 2-stroke engines. The four-stroke engine also benefits from lower pollutant emission and has better fuel consumption. There is no need to mix fuel, in contrast to 2-stroke engines. Simply use unleaded petrol with min. 95 RON (super unleaded petrol with 95 octane).

The petrol brushcutter is simple to start thanks to the easy-start system. The pull-cord is very easy to pull thanks to the internal auxiliary spring. This means that the engine is significantly easier and more comfortable to start. The trimmer is also equipped with a primer and a choke lever. The primer is a petrol pump (rubber push-pump) that pumps petrol into the fuel lines and carburettor of the petrol brushcutter when pushed, before the engine is started. The choke is the starter lever. Once the engine has been started, set the choke lever to the RUN position and control the engine speed of the device with the throttle lever.

Lay the brushcutter on the ground to start the engine. Ensure that the cutter or the spool are free and not in the grass. The surface used should be level and free of stones. First, push the choke lever (start lever) to the START position. Now press the primer (injection button).

If you are starting the brushcutter for the first time or after it has been unused for a long period of time, e.g. before the first lawn cutting in spring, press the primer (injection button) 5x. This process and this device makes the engine start easier. With every subsequent engine start, before strimming or cutting undergrowth, it is only necessary to press the primer 3x. The primer need not be pressed again any time the engine is restarted during the mowing work. Do not press the primer too many times as otherwise the engine of the brushcutter could be flooded. This would make the engine more difficult to start.

After the petrol has been pumped into the carburettor with the help of the primer, push the starter button on the side of the right grip to ON. Now pull the start-cord 2-3 times. As soon as you can tell that the engine is starting, push the choke lever to the RUN position and pull the start-cord once again. The engine will start. After the engine starts it will settle at idle. The cutting device will not yet be moving. It will only move when the throttle lever is pressed. Now you can pick up the device and clip it into the shoulder strap that you are already wearing. Control the engine speed carefully with the throttle lever on the right grip. Do not use full throttle immediately. In order to avoid having to keep the throttle lever pressed throughout the entire working period, you can press the locking button on the side and the throttle will be locked in the open position until you release the lock again by pressing the throttle lever.

The petrol tank can hold max. 680 ml of petrol. The oil tank holds 80ml of engine oil. Both tanks are furnished with a practical screw closure. To fill the petrol and oil tanks, lay the device flat on the ground. There is an oil dipstick on the cover of the oil tank in order to be able to read how much oil is in the tank in comfort - just as you would with a car.

The brushcutter runs significantly more smoothly and also has a lower wear rate thanks to the double bearings on the crankshaft. The chromed aluminium cylinder and the rigid, chromed drive shaft make the device more durable. The air filter can be replaced without tools. So, the filter change can be carried out without the assistance of other tools.

The petrol brushcutter is extremely simple to handle. The brushcutter is simple to operate and very efficient for trimming and cutting grass and undergrowth. The petrol brushcutter is particularly easy and light to guide thanks to the handy and ergonomic bike handlebars and the double shoulder strap provided.

The double shoulder strap provided fastens the device perfectly to the body. Working comfort is increased significantly by this as you no longer need to bear the whole weight of the tool with hands and arms alone. Stresses on hands, wrists, arms, shoulders and back are reduced. You have better control of the device when using the shoulder strap. This prevents rapid fatigue and promotes good posture when working. It allows you to work whilst taking care of your shoulders and back. The shoulder strap can be easily fastened to the brushcutter with a clip. The size of the shoulder strap can be individually adjusted and can therefore be adapted to suit needs. The carry strap ensures the best possible handling and guidance of the brushcutter. The sturdy plastic hip protector serves as protection between the device and your hips, thus avoiding pressure spots on your body. The integrated emergency cord is a safety device in order to quickly release the strap from the body in the event of an emergency, by pulling on the cord.

The bike handlebars enable the petrol brushcutter to be perfectly controlled – secure and comfortable guidance of the motor brushcutter is assured. Always hold the device firmly with both hand grips. The controls such as choke lever, start button and throttle lever are ergonomically attached to the right bike grip. This ensures that the brushcutter can be intuitively controlled.

As mentioned above, the petrol brushcutter is delivered with a cutting line spool. If the cutting line becomes too short while being used, the automatic tapping feed (semi-automatic cutting line feed) will ensure that simply "tapping the spool" on the ground will provide quick and simple lengthening of the cutting line. The spring mechanism in the cutting line cartridge is activated by the tapping and centrifugal force lengthens the nylon cutting line. The nylon cutting line is fed out of the cutting line housing by tapping and is then automatically cut to the correct length by the cutting blade on the semi-circular protective cover. The automatic tapping feed also prevents the cutting line becoming entangled. You can purchase replacement spools from us in the IKRA online shop. The cutting line spool used is a twin-line spool. The cutting line cartridge has two outlet eyes for the cutting line. Twin-line spools cut the grass even more effectively and the spool also runs more quietly. The cutting line is not used up so quickly.

Innovation: Grass entanglement protection device: With conventional brushcutters there is a gap between the angled transmission and the spool. This gap is often several millimetres wide. Grass gladly entangles itself here, particularly when cutting tall stalks. This grass is difficult to remove from the gap, especially when it has dried. If this is not removed when the tool is cleaned, the grass entangled in the gap can result in the tool being damaged when started up again. The innovative grass entanglement protection on this brushcutter prevents grass entanglement. The angular transmission is fitted tight against the spool so that there is no gap where grass can be caught or entangled.

The rear protective cover, which faces you when you are working, protects your shoes from the rotating cutting line and the cutting blades. The cover also ensures that the cut grass is not swirled around and thrown backwards too much. Only half of the swept path of the rapidly rotating cutting line is covered by the protective plastic cover. The advantage of the open section is that you can also cut very close to the edging, edges and corners of walls, for example. Try to ensure that the cutting line does not come into contact with hard surfaces, such as stone, wood and steel, as this wears out the nylon cutting line faster. The surfaces are not normally damaged by contact with the cutting line. You should not work too close to the edge with the cutting blades are contact with hard objects could cause a kickback. Contact could damage the cutting blade and the surface.

After you are finished working with the brushcutter, you can split the sturdy and durable aluminium tube with the help of the quick-fastener to save space when storing it. The aluminium tube has a diameter of ca. 26 mm. Thick tube for increased stability and reduced vibrations. The cellar, garage or garden shed, for example, would be ideal for storage.
