5.2. Adjusting the cutting height

Slip the shoulder strap (15) over your left shoulder.

To establish the optimum length of the har- ness, you should then make a few swinging movements without starting the engine (Fig. 11a). Warning! Always use the strap when working with the equipment. Attach the strap as soon as you have started the engine and it is running in idle mode. Switch off the engine before you take off the carrying strap.

6. Before starting the equipment

Check the equipment for the following each time before use:

That there are no leaks in the fuel system.

That the equipment is in perfect condition and that the safety devices and cutting devices are complete.

That all screws are securely fastened.

That all moving parts move smoothly.

Recommended fuels Use only a mixture of unleaded petrol and special 2-stroke engine oil. Mix the fuel mixture as indica- ted on the fuel mixing table. Important: Do not use a fuel mixture which has been stored for longer than 90 days. Important: Never use 2-stroke oil with a recom- mended mixing ratio of 100:1. The manufacturer’s warranty will be voided in case of engine damage due to inadequate lubrication. Important: Only use containers designed and ap- proved for the purpose to transport and store fuel. Pour the correct quantities of petrol and 2-stroke oil into the mixing bottle (see scale printed on the bottle). Then shake the bottle well.

6.2 Fuel mixture table

Mixing procedure: 40 parts petrol to 1 part oil Petrol 2-stroke oil 1 liter 25 ml 5 liters 125 ml

Please note that the statutory regulations gover- ning noise abatement may diff er from town to town. Before starting up the equipment remove the pro- tective caps from the cutting blade (18).

7.1 Starting the engine when cold

Fill the tank with an adequate amount of petrol/oil mix. See „Fuel and oil“.

1. Set the equipment down on a hard, level sur-

2. Press the fuel pump (primer) (Fig. 14a/Item

throttle lever lock (Fig. 1/Item 12) and then the throttle lever (Fig. 1/Item 11), and secure the throttle lever by pressing the lock (Fig. 1/Item

6. Hold the equipment securely and pull out the

starter cable (Fig. 1/Item 4) until you feel it begin to resist. Then tug sharply on the starter cable 4 times. The equipment should start. Note: Never allow the starter line to snap back. This may result in damage.

Warning: Since the throttle lever is secured,

the cutting tool will start to operate when the engine is started. Once the engine has started, move the choke lever immediately to OFF and allow the equipment to warm up for approx. 3 seconds. Then release the throttle lever by simply actuating it (the engine then returns to running in idle mode).

7. If the engine does not start up, repeat steps

4-6 above. Please note: If the engine does not start up even after several attempts, read the Engine trouble- shooting section. Please note: Always pull out the starter cable in a straight line. If it is pulled out at an angle, friction will occur on the eyelet. As a result of this friction, the cable will become frayed and will wear faster. Always hold the starter handle when the cable retracts. Never allow the cable to snap back when it has been pulled out. Anl_BBC_52_SPK7.indb 20Anl_BBC_52_SPK7.indb 20 13.01.16 08:3113.01.16 08:31GB

7.2 Starting the engine when warm

(The equipment has been idle for less than 15-20 min.)

1. Set the equipment down on a hard, level sur-

3. Secure the throttle lever (in the same way

as described in “Starting the engine when cold”). Hold the equipment fi rmly and pull out the starter cable until you feel it start to resist. Then tug sharply on the starter cable. The equipment should start after 1-2 tugs. If the equipment does not start after 6 pulls, repeat steps 1 to 7 of the procedure for starting the engine when cold.

7.3 Switching off the engine

Emergency Stop procedure: If it becomes necessary to stop the equipment im- mediately, set the ON/OFF switch to “Stop” or “0” Normal procedure: Let go of the throttle lever and wait until the engi- ne has changed to idling speed. Then set the ON/ OFF switch to “Stop” or “0”.

Practice all operating techniques with the engine switched off before you start to use the equip- ment.

8. Working with the petrol power

scythe Extending the cutting line Caution! Do not use any kind of metal wire or metal wire encased in plastic in the line spool. This may cause serious injuries to the user. To extend the cutting line, run the engine at full speed and tap the line spool on the ground. This will automatically extend the line. The blade on the safety shield will cut the line to the appropriate length (Fig. 11b). Important: Remove all grass and weed remnants at regular intervals to prevent the shaft tube over- heating. Lawn, grass and weed remnants become trapped under the safety shield (Fig. 11c) and prevent the shaft tube from receiving adequate ventilation. Remove the remnants carefully using a screwdriver or the like. Diff erent cutting methods When the equipment is correctly assembled it will cut weeds and long grass in places which are diffi cult to access, e.g. along fences, walls and foundations and also around trees. It can also be used for „mowing“ down vegetation so that a garden can be better prepared or a certain area cleared down to the soil. Please note: Even if it is used carefully, cutting around foundations, stone or concrete walls, etc. will result in the line suff ering more than normal wear. Trimming/mowing Swing the trimmer from side to side in a scything motion. Always keep the line spool parallel to the ground. Check the site and decide which cutting height you require. Guide and hold the line spool at the required height to obtain an even cut (Fig. 11d). Low trimming Hold the trimmer right in front of you at a slight angle so that the underside of the line spool is above the ground and the line strikes the correct target. Always cut away from yourself. Never draw the trimmer towards yourself. Cutting along fences/foundations Approach wire mesh fences, lath fences, natural stone walls and foundations slowly so that you can cut close to them without striking the obstac- le with the line. If, for example, the line strikes stones, stone walls or foundations, it will wear or fray. If the line strikes wire fencing, it will break. Trimming around trees When trimming around tree trunks, approach slowly so that the line does not strike the bark. Walk around the tree, cutting from left to right. Ap- proach grass or weeds with the tip of the line and tilt the line spool forwards slightly. Warning! Take extreme care during mowing work. When doing such work keep a distance of 30 meters between yourself and other people or animals. Mowing When mowing, you want to cut all the vegetation down to the ground. To do this, set the line spool at an angle of 30° to the right. Place the handle in the required position. Remember the increased risk of injury to the user, watchers and animals, and the danger of damaging property due to ob- Anl_BBC_52_SPK7.indb 21Anl_BBC_52_SPK7.indb 21 13.01.16 08:3113.01.16 08:31GB

jects (for example stones) being thrown up (Fig. 11e). Warning! Do not use the equipment to remove objects from footpaths, etc. The equipment is a powerful tool and can throw small stones and other objects a distance of 15 meters or more, causing injuries and damage to cars, houses and windows. Sawing The equipment is not suitable for sawing. Jamming If the cutting blade jams as a result of attempting to cut vegetation that is too dense, switch off the engine immediately. Remove the grass and scrub from the equipment before you restart it. Preventing recoil When you work with the blade, there is a risk of recoil if it strikes solid objects such as tree trunks, branches, tree stumps, stones or the like. This will throw the equipment backwards in the direction opposite to the rotation of the tool. This can cause you to lose control of the equipment. Do not use the blade near fences, metal posts, boundary stones or foundations. For cutting dense stalks, position the blade as shown in Fig. 9f to prevent recoil.

Always switch off the equipment and pull out the spark boot plug before carrying out any mainte- nance work.

9.1 Replacing the line spool/cutting line

1. Dismantle the line spool (16) as described in

section 5.1.8. Press in the side lugs slightly

while simultaneously pressing the spool down and turning it clockwise (Fig. 15a). Remove one half of the housing.

2. Take the line spool out of the line spool

3. Remove any remaining cutting line.

4. Place the new cutting line in the center and

hang the loop which has formed into the re- cess in the spool splitter (Fig. 15d)

5. Wind up the line counter-clockwise and under

tension. The spool splitter will separate the two halves of the line (Fig. 15e)

6. Hook the last 15cm of the two ends of the

line onto the opposite lying line holders of the spool plate (Fig. 15f)

7. Thread the two ends of the line through the

metal eyelets in the line spool housing (Fig. 15c).

8. Press the line spool into the line spool

9. Pull the two line ends sharply to release them

from the line holders.

10. Cut the excess line to a length of around 13

cm. This will reduce the load on the engine when starting and warming up.

11. Refi t the line spool (see section 5.1.8). If you

are replacing the complete line spool, skip points 3-6.

9.2 Grinding the safety hood blade

The safety hood blade can become blunt over time. When you notice this, undo the screw hol- ding the safety hood blade on the safety hood. Clamp the blade in a vise. Sharpen the blade with a fl at fi le and make sure that the angle of the cut- ting edge is not altered in the process. File in one direction only.

9.3 Maintenance of the air fi lter

Soiled air fi lters reduce the engine output by supplying too little air to the carburetor. Regular checks are therefore essential. The air fi lter (37) should be checked after every 25 hours of use and cleaned if necessary. If the air contains a lot of dust, the air fi lter must be checked more fre- quently.

3. Clean the air fi lter by tapping it or blowing it

4. Assemble in reverse order.

Important: Never clean the air fi lter with petrol or infl ammable solvents.

9.4 Maintenance of the spark plug

Spark plug sparking gap = 0.6mm. Tighten the spark plug with a torque of 12 to 15 Nm. Check the spark plug for dirt and grime after 10 hours of operation and if necessary clean it with a copper wire brush. Thereafter service the spark plug after every 50 hours of operation.

3. Assemble in reverse order.

Warning! Settings on the carburetor may only be made by authorized customer service personnel. The air fi lter cover must be removed before any work on the carburetor, as shown in Figures 12a and 12b. Setting the throttle cable: If the maximum speed of the equipment drops over time and you have ruled out all the other possible causes listed in section 12 „Troubleshoo- ting“, it may be necessary to adjust the throttle cable. First of all check whether the carburetor opens fully when the throttle handle is pressed right through. This is the case if the carburetor slide (Fig. 13a) is completely opened when the throttle is fully activated. Figure 13a shows the correct setting. If the carburetor slide is not com- pletely open, it must be adjusted. The following steps are required to adjust the throttle cable:

Undo the lock nut (Fig. 13a/Item C) a few turns.

Undo the adjusting screw (Fig. 13a/Item D) until the carburetor slide is completely open when the throttle is fully activated, as shown in Figure 13a.

9.6 Setting the idling speed

Warning! Set the idling speed when the equip- ment is warm. If the engine stalls when the throttle is not pressed and you have ruled out all the other possible causes listed in section 12 „Troubleshooting“, the idling speed must be adjusted. To do this turn the idling speed screw (Fig. 13a/Item E) clockwise until the equipment runs smoothly at idling speed. If the idling speed is so fast that the cutting tool turns as well, it has to be reduced by turning the idling speed screw for as long as is required for the cutting tool to stop turning as well.

10. Cleaning, storage, transport and

ordering of spare parts

Keep the handles free of oil so that you can maintain a firm grip.

Clean the equipment as required with a damp cloth and, if necessary, mild washing up liquid. Important! Always pull out the spark boot plug each time before carrying out any cleaning. Never immerse the equipment in water or other liquids in order to clean it. Store the equipment in a safe and dry place out of the reach of children.

Important: Never put the equipment into storage for longer than 30 days without carrying out the following steps. Storing the equipment If you intend to store the equipment for longer than 30 days, the equipment must be prepared accordingly. Otherwise the fuel still remaining in the carburetor will evaporate and leave a rubbery sediment. This can cause problems when starting up the equipment and may require expensive repairs.

1. Slowly remove the fuel tank cap to release

any pressure that may have formed in the tank. Carefully empty the tank.

2. To remove the fuel from the carburetor, start

the engine and let it run until it stops.

3. Leave the engine to cool (approx. 5 minutes).

4. Remove the spark plug (see section 9.4).

5. Add one teaspoon of 2-stroke engine oil into

the combustion chamber. Slowly pull the star- ter cord several times to apply a layer of oil to all internal components. Fit the spark plug again. Note: Store the equipment in a dry place and far away from possible ignition sources such as an oven, a gas-fi red hot water boiler, a gas-fi red dryer, etc. Putting the equipment back into operation

1. Remove the spark plug (see section 9.4).

2. Quickly tug on the starter cord to remove ex-

cess oil from the combustion chamber.

3. Clean the spark plug and check that the

electrode gap is correct, or insert a new spark plug with the correct electrode gap.

4. Prepare the equipment for operation.

5. Fill the tank with the relevant mixture of fuel

To transport the machine, empty the petrol tank as described in section 10. Clean coarse dirt off the equipment with a brush or hand brush.
