Mounting the trimmer guard
Warning! The trimmer guard must be mounted correctly in order to protect the user and so that the trimmer
line will be the correct length. The guard contains a blade which automatically cuts off the line to an appro-
priate length when the trimmer head begins rotating.

2. Hold the trimmer head and use your hand or the enclosed spanner to undo the trimmer head nut.
3. Remove the trimmer head from the spindle.
4. Slide the trimmer guard over the shaft and align the holes in the guard with holes in the bracket.
(See g above.)
5. Push in the bolt through the trimmer guard from the side with the hexagonal countersink. Tighten the bolt
using the washer and nut.
6. Reassemble the trimmer head onto the spindle.

Fuel and Lubrication
Caution! Petrol is highly ammable. Avoid smoking near any area where fuel will be handled. Do
not introduce open res, embers or sparks into the area. Switch off the grass trimmer and let it cool
before refuelling it. Refuel outdoors and always move at least 3 metres away from the refuelling site
before starting the trimmer.
Mix petrol (unleaded 95 octane without added ethanol) with a good quality 2-stroke oil intended for air-cooled
2-stroke engines.
Recommended mixture: Petrol/oil 40:1 (2.5 %)
• The engine is designed to be used with unleaded fuel.
• Use at least an 87 rated octane fuel.
• Use unleaded fuel to protect the environment and your health.
• Bad quality fuel or oil can damage seals, fuel pipes or the fuel tank.
Mixing the fuel
N.B. Be precise with the mixture.
1. Measure out the petrol and oil precisely before mixing.
2. Pour a small amount of the petrol into a clean approved fuel container.
3. Pour in all of the oil and agitate the fuel can.
4. Pour in the rest of the petrol and agitate the fuel can for at least a minute. Some oils are difcult to mix. It
is therefore important to agitate the container in order for the oil and petrol to mix thoroughly. The engine
will last longer if the fuel is well mixed, if the fuel is not mixed properly the mixture will be too lean and the
engine may be damaged.
5. Label the fuel can clearly to avoid the risk of misidentication.
6. Fuel containing oil is only intended for 2-stroke engines. Pure petrol is for 4-stroke engines. It is therefore
very important to label fuel containers clearly.
N.B. Do not mix too much fuel; it should be used within 90 days.
Caution! Only use fuel containing oil for 2-stroke engines, using pure petrol without the addition of oil will
inevitably cause engine damage which is not covered by the guarantee.
Fueling the trimmer
1. Let the trimmer cool before refuelling it.
2. Unscrew and remove the fuel cap.
3. Fill with fuel until the tank is roughly 80% full.
4. Replace and tighten the fuel cap and wipe up any spilt fuel on or around the grass trimmer.

Starting the Engine
N.B. Pull the starter handle straight out. If you pull at an angle the starter cord will rub on the sleeve and
wear out prematurely. Keep hold of the starting handle after pulling it and allow it to return slowly. Never re-
lease the starter handle completely at full length since it can become entangled and the backlash can break
something on the trimmer.
N.B. See the Troubleshooting section if the trimmer doesn’t start after several attempts.
Starting a cold engine
Cut the trimmer line to a length of 13 cm before starting to reduce the load while
the trimmer warms up.
1. Place the grass trimmer on a level surface.
2. Set the on/off switch to position 1.
3. Set the choke lever (17) to cold start mode (upwards).
4. Press the primer pump (15) 10 times.
5. Hold the upper handle rmly while simultaneously pressing and holding in the safety lock and throttle.
6. Pull the starter handle until you feel some resistance (approx. 100 mm) Pull the starter handle quickly
and smoothly until the engine starts or up to 4 times.
7. Set the choke lever to the open position (downwards) as soon as the engine starts.
