ADVERTÊNCIAS ESPECÍFICAS SOBRE O LIXADOR • • • Não use esta ferramenta se a velocidade livre total exceder a rpm indicada na placa de identificação. Antes de montar a correia de lixamento, depois de qualquer reparação de ferramenta ou quando se pretende que um Lixador seja colocado em funcionamento, verifique a velocidade livre do Lixador com um tacómetro para se certificar de que a sua velocidade real a 6,2 bar/620kPa (90 psig) não exceda a rpm selada ou impressa na placa de identificação. Os Lixadores em funcionamento devem ser similarmente verificados pelo menos uma vez em cada turno. • • Use sempre o Protector do Disco da Ingersoll–Rand fornecido com o Lixador. Os Lixadores em Ângulo Séries CA120 têm uma velocidade livre de 12 000 rpm e uma velocidade de correia de 2 700 sfpm enquanto os das Séries CA200 têm velocidade livre de 20 000 rpm e uma velocidade da correia de 4500 sfpm, quando operados sob uma pressão de ar igual a 6,2 bar/620 kPa (90 psig). Operação sob pressões de ar mais elevadas resultará em velocidade excessiva. Nao opere o lixador com correia com a capa removida. AJUSTES INSTALANDO UMA CORREIA DE LIXAMENTO 3. 4. Quando uma correia de lixamento nova for instalada proceda da seguinte maneira: 1. Para modelos com 18”, deslize a Capa para trás em direção ao punho do Lixador até libertá–la. Pode ser necessário uma leve pancada na extremidade frontal da capa para livrá–lo dos seus pontos de travamento. 2. Comprima o Disco Falso e retire a correia velha para fora da Camisa de comando. Alivie a pressão no Disco Falso e remova a correia. 5. 6. 12 Posicione a correia nova no Disco Falso. Comprima o Disco Falso com a correia e coloque a extremidade oposta da correia na Camisa de Comando ao redor do Tampo do Fuso. Alivie a pressão no Disco Falso. Para modelos com 18”, alinhe a Capa com o Protector e deslize para frente em direção do Disco Falso até que ele prenda na posição e lá permaneça. Opere o Lixador com velocidade baixa para verificar se a nova Correia está propriamente colocada. Se a Correia não correr no trilho de maneira apropriada, realinhe o Olhal ao apertar ou afrouxar um ou ambos Parafusos de Montagem do Olhal. COLOCANDO A FERRAMENTA EM FUNCIONAMENTO OPERAÇÃO DA FERRAMENTA CUIDADO Lixe usando qualquer porção da Correia de Lixamento exposta. Para resultados melhores, lixe naquela porção da Correia sendo puxada pelo Disco de Comando. Não marque as superfícies não metálicas desta ferramenta com códigos de identificação do cliente. Tais acções podem afectar o desempenho da ferramenta.
