9.5 GRASS THINNING USING A GRASS BLADE

9.5.1 Check before starting

• Examine the blade for cracks in the base of the teeth or the area near the center hole.

Replace the blade if it shows cracks (see chapter 5.3 Blade assembly (Fig. 10)).

• Check that the support flange is not cracked due to fatigue or due to being tightened too

much. Replace the support flange if it appears cracked (see chapter 5.3 Blade assembly

(Fig. 10)).

• Ensure that the retaining nut (A, Fig. 10) has not lost its holding capacity. The tightening

force of the retaining nut must be 25 Nm.

• Check that the blade cover (A, Fig. 4) is not damaged or cracked. Replace the blade cover if

it appears cracked.

NOTE

A grass blade is used for all types of tall or coarse grass.

9.5.2 Working methods

WARNING

• Avoid kickback as it can cause serious injury. Kickback is the sudden lateral or

forward movement of the machine which occurs if the blade comes into contact

with objects such as large branches or stones, or if a piece of wood hits the wood

blade during cutting. Contacting a foreign object can also result in loss of brush

cutter control.

• Always follow the safety instructions. The brushcutter should only be used to cut

grass or small bushes. Only cut wood with the appropriate blade. Do not cut

metal, plastics, masonry, or non-wood building materials. Cutting other types of

material is prohibited. Do not use the brushcutter as a lever to lift, move or

break objects, nor lock it on fixed supports. It is prohibited to fit any tools or

applications to the brushcutter PTO other than those specified by the

Manufacturer.

• Avoid cutting near fences, building walls, tree trunks, stones or other objects

that may cause the machine to jolt or damage the blade. We recommends use of

the nylon line heads for such jobs. In addition, be alert to an increased

possibility of ricochets in such situations.

• Never use the machine with the cutting device in a position perpendicular to the

ground.

• Never operate the machine with the blade loose. If the blade becomes loose

after being properly secured, discontinue use immediately. The retaining nut

may be worn or damaged and should be replaced. Never use unapproved parts

to secure the blade. If the blade continues to loosen, see your dealer.

• The grass is cut down with a sideways, swinging movement, where the movement from

right-to-left is the thinning stroke and the movement from left-to-right is the return stroke.

Cutting is done with the left side of the blade, as shown in Fig. 25.

• If the blade is angled to the left when thinning grass, the grass will collect in a line, which

makes it easier to collect, e.g. by raking.
