Sikkerhedsinstruktioner
1. Maskinens lufttryk må aldrig overstige det maksimale arbejdstryk, hvilket er 0.63MPa.
2. Luftslangen skal altid tømmes for luft inden maskinen kobles fra. Slangen skal fjernes fra maskinen inden værktøjet
skiftes.
3. Det skal være muligt at lukke for lufttilførslen til maskinen ved hvert arbejdssted.
4. Luftslangen skal blæses igennem inden den tilsluttes maskinen og der skal sidde en prop på maskinens
luftindgang når maskinen ikke bruges.
5. Slangekoblinger skal sidde ordentlig fast i maskinen og være ordentligt fastmonteret på slangen.
Hvis en slangekobling anvendes forkert eller er monteret forkert, kan slangen løsne og forårsage skader ved
"slangekast". Luftslange og koblinger skal efterses og skiftes regelmæssigt for at forhindre slidtage og skader.
6. Anvend ikke andet tilbehør end det foreskrevne med korrekt skaft diameter. Skæreskiver og grovkornede skiver må
ikke anvendes.
7. Kontroller at tilbehørets maksimale hastighed er højere end hastigheden på sliberen.
8. Kontroller altid at patronen i maskinen er den korrekte størrelse i forhold til skaftet på tilbehøret. Det er farligt at
ændre skaftdiameteren eller at tvinge et skaft ned i en spændepatron af forkert størrelse.
9. Når det monterede tilbehør anvendes, vær især opmærksom på, at den tilladte hastighed på tilbehøret er lavere,
p.g.a. forlængelsen af skaftet mellem enden af patronen og det monterede tilbehør (udhæng). Sørg for at
gribelængden er minimum 10mm.
10. Vær opmærksom på at patronen passer til skaftstørrelsen på tilbehøret der skal monteres, og at spændemøtrikken
er fastskruet så tilbehøret er monteret ordentligt.
11. Brug aldrig tilbehør, som er forkert monteret og ødelagt da dette kan resultere i voldsomme vibrationer i patronen.
12. Før værktøjet tilsluttes luft skal oplukkerhåndtaget kontrolleres d.v.s. at det fungerer korrekt.
13. Brugere af trykluftdrevne lynslibere skal før ibrugtagning instrueres i korrekt brug:
(A) Hold hænder, løsthængende tøj og langt hår borte fra roterende dele af maskinen under brug.
(B) Gennemgå sikkerhedsreglerne ved brug af maskinen.
(C) Brugeren skal instrueres i korrekt brug og montering af slibematerialer, file m.m.
