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

such as fences, walls, tree trunks and stones.

5. Never use cutting blades vertically, for

such operations as edging and trimming hedges. ►Fig.3 Vibration

1. People with poor circulation who are exposed

to excessive vibration may experience injury to blood vessels or the nervous system. Vibrationmaycausethefollowingsymptoms tooccurinthengers,handsorwrists:"Falling asleep"(numbness),tingling,pain,stabbingsen- sation,alterationofskincolororoftheskin.Ifany ofthesesymptomsoccur,seeaphysician!
