Grass trimmer head

•  Make sure that you wind the grass trimmer line tightly and equally around the drum to decrease the vibration.
• Use only the approved grass trimmer heads and grass trimmer lines. Refer to Accessories on page 14.
• Use a correct length of the grass trimmer line. A long grass trimmer line uses more engine power than a short grass trimmer line.
• Make sure that the cutter on the cutting attachment guard is not damaged.
• Soak the grass trimmer line in water for 2 days before you attach the grass trimmer line to the product. This increases the life of the grass trimmer line.
• Refer to the instructions for the cutting attachment to use the correct procedure to load the cord and the correct cord diameter.

Gras

blades and grass cutters

• Use head protection when you operate a product with a grass blade.
• Grass blades and grass cutters are used to cut rough grass.
• A grass blade can cause injury while it continues to spin after the engine is stopped or the throttle trigger is released. Make sure that the grass blade has completely stopped rotating before any maintenance.
• Stop the engine before you do work on the cutting attachment. Make sure the cutting attachment fully stops. Disconnect the lead from the spark plug.
• Only use an approved cutting attachment or a correctly sharpened blade.
• Keep the teeth of the blade correctly sharpened.(Fig. 23)
• Do not use a damaged cutting attachment.
• Attach the transport guard to the grass blade when you transport or store the product.

Blade thrust

•  A blade thrust is a sudden movement of the product to the side, forward or rearward. A blade thrust occurs when the grass blade or saw blade hits an object that cannot be cut. In areas where it is not easy to see the material being cut the risk of blade thrust increases.
• When a blade thrust occurs, there is a risk that the product or the operator moves out of position. A blade that moves can hit bystanders and there is a risk of injuries.
• If a blade is bent, has cracks, is broken or damaged, discard the blade.
• Use a sharp blade. The risk of blade thrust increases when a blade is not sharp.

Note: Do not pull the throttle trigger while you start the engine.

To start a warm engine

1. Push the primer bulb 10 times.
2.  Pull the starter rope until the engine starts.

Push the stop switch to stop the engine. (Fig. 32)

Note: The stop switch automatically goes back to its initial position.

To operate the grass trimmer

CAUTION: Make sure that you slow the engine to idle speed after each operation. A long period at full throttle without a load on the engine can cause damage to the engine.

Note: Clean the cover of the trimmer head when you attach a new trimmer line to prevent vibrations. Examine other parts of the trimmer head and clean if it is necessary.

To trim the grass

1. Hold the trimmer head immediately above the ground at an angle. Do not push the trimmer line into the grass. (Fig. 33)
2. Decrease the length of the trimmer line by 10-12 cm / 4-4.75 in.

3. Move the product from side to side when you cut grass. Use full speed. (Fig. 36)

To clear grass with a grass blade

1. Grass blades and grass cutters must not be used on woody stems.
2. A grass blade is used for all types of tall or coarse grass.
3. The grass is cut down with a sideways, swinging movement, where the movement from right-to-left is the clearing stoke and the movement from left-to-right is the return stoke. Let the left-hand side of the blade (between 8 and 12 o’clock) do the cutting.
4. if the blade is angled to the left when clearing grass, the grass will collect in a line, which makes it easier to collect, e.g. by raking.
5.  Try to work rhythmically. Stand firmly with your feet apart. Move forward after the return stoke and stand firmly again.
6. Let the support cup rest lightly against the ground. It is used to protect the blade from hitting the ground.
7. Reduce the risk of material wrapping around the blade by always work at full throttle and avoid the previously cut material during the return stoke.
8. Stop the engine, unclip the harness and place the machine on the ground before you start to collect the cut material.

Note 1: Reported data for equivalent vibration level has a typical statistical dispersion (standard deviation) of 1 m/s2.

Note 2: Noise emissions in the environment measured as sound power (LWA) in conformity with EC directive 2000/14/ EC. Reported sound power level for the machine has been measured with the original cutting attachment that gives the highest level. The difference between guaranteed and measured sound power is that the guaranteed sound power also includes dispersion in the measurement result and the variations between different machines of the same model according to Directive 2000/14/EC.

Note 3: Reported data for equivalent sound pressure level for the machine has a typical statistical dispersion (standard deviation) of 1 dB (A).
