Method of operation

Only use in good light and visibility. During the winter season beware of 

 

slippery or wet areas, ice and snow (risk of slipping). Always ensure a safe 

footing.
Never cut above waist height.

 

Never stand on a ladder.

 

Never climb up into trees to perform cutting operation.

 

Never work on unstable surfaces.

 

Remove sand, stones, nails etc. found within the working range.

 

Foreign particles may damage the cutting tool and can cause dangerous kick-

backs.
Before commencing cutting, the cutting tool must have reached full working 

 

speed.
When using metal blades, swing the tool evenly in half-circle from right to left, 

 

like using a scythe. 

If grass or branches get caught between the cutting tool and guard, always 

stop the engine before cleaning. Otherwise unintentional blade rotation may 

cause serious injury.
Take a rest to prevent loss of control caused by fatigue. We recommend to 

 

take a 10 to 20-minute rest every hour.

Cutting Tools

Use an applicable cutting tool for the job in hand.

 

Metal blades are suitable for cutting weeds, high grasses, bushes, shrubs, 

underwood, thicket, and the like. 

Never use other blades including metal multi-piece pivoting chains and flail 

blades. Otherwise serious injury may result.
When using metal blades, avoid “kickback” and always prepare for an 

 

accidental kickback. See the section “Kickback” and “Kickback prevention.”

Kickback (blade thrust)

Kickback (blade thrust) is a sudden reaction to a caught or bound cutting 

 

blade. Once it occurs, the equipment is thrown sideway or toward the 

operator at great force and it may cause serious injury.
Kickback occurs particularly when applying the blade segment between 12 

 

and 2 o’clock to solids, bushes and trees with 3 cm or larger diameter.
To avoid kickback:

 

Apply the segment between 8 and 11 o’clock;

 

Never apply the segment between 12 and 2 o’clock;

 

Never apply the segment between 11 and 12 o’clock and between 2 and 

 

5 o’clock, unless the operator is well trained and experienced and does it at 

his/her own risk;

Never use cutting blades close to solids, such as fences, walls, tree trunks 

 

and stones;

Never use cutting blades vertically, for such operations as edging and 

 

trimming hedges.

Vibration

People with poor circulation who are exposed to excessive vibration may 

 

experience injury to blood vessels or the nervous system. Vibration may 

cause the following symptoms to occur in the fingers, hands or wrists: “Falling 

asleep” (numbness), tingling, pain, stabbing sensation, alteration of skin color 

or of the skin. If any of these symptoms occur, see a physician!
To reduce the risk of “white finger disease”, keep your hands warm during 

 

operation and well maintain the equipment and accessories.

Maintenance instructions

Have your equipment serviced by our authorized service center, always using 

 

only genuine replacement parts. Incorrect repair and poor maintenance can 

shorten the life of the equipment and increase the risk of accidents.
The condition of the cutter, in particular of the cutting tool of the protective 

 

devices and also of the shoulder harness must be checked before 

commencing work. Particular attention is to be paid to the cutting blades 

which must be correctly sharpened.
Turn off the engine and remove spark plug connector when replacing or 

 

sharpening cutting tools, and also when cleaning the cutter or cutting tool.
