Before the inspection, remove the battery

cartridge and wait until the cutting attachment

stops completely. Replace damaged cutting

attachment immediately, even if it has only



16. Never cut above waist height.

17. Before starting the cutting operation, wait until

the cutting attachment reaches a constant

speed after turning the tool on.

18. When using a cutting blade, swing the tool

evenly in half-circle from right to left, like

using a scythe.

19.

Hold the tool by insulated gripping surfaces

only, because the cutter blade may contact

hidden wiring. Cutter blades contacting a "live"

wire may make exposed metal parts of the tool

"live" and could give the operator an electric shock.

20. Do not start the tool when the cutting tool is

tangled with cut grass.

21. Before starting the tool, be sure that the cut-

ting tool is not touching the ground and other

obstacles such as a tree.

22. During operation always hold the tool with

both hands. Never hold the tool with one hand

during use.

23. Do not operate the tool in bad weather or if

there is a risk of lightning.

Cutting tools

1. Do not use a cutting tool which is not recom-

mended by us.

2. Use an applicable cutting attachment for the

job in hand.

— Nylon cutting heads (string trimmer heads)

and plastic blades are suitable for trimming

lawn grass.

— Cutting blades are suitable for cutting weeds,

high grasses, bushes, shrubs, underwood,

thicket, and the like.

— Never use other blades including metal

3. Only use the cutting tool that are marked with

a speed equal or higher than the speed marked

on the tool.

4. Always keep your hands, face, and clothes

away from the cutting tool when it is rotating.



5. Always use the cutting attachment guard prop-

erly suited for the cutting attachment used.

6. When using cutting blades, avoid kickback

and always prepare for an accidental kickback.

See the section for Kickback.

7. When not in use, attach the blade cover onto

the blade. Remove the cover before operation.

Kickback (Blade thrust)

1. Kickback (blade thrust) is a sudden reaction

to a caught or bound cutting blade. Once it

occurs, the tool is thrown sideway or toward

the operator at great force and it may cause

serious injury.

2. 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.

Fig.2

3. To avoid kickback:

1.

Apply the segment between 8 and 11 o'clock.

2. Never apply the segment between 12 and

2 o'clock.

3. 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.

4. Never use cutting blades close to solids,

such as fences, walls, tree trunks and

stones.

5. Never use cutting blades vertically, for

such operations as edging and trimming

hedges.
