OPERATION AND MAINTENANCE MANUAL FOR

MODELS 180PQ1, 280P AND 280PQ1

TWIN BLADE IMPULSE WRENCHES

Models 180PQ1, 280P and 280PQ1 Impulse Wrenches are designed for use in assembly operations requiring consistent torque. They are ideally suited to appliance assembly and applications requiring low noise levels.

Ingersoll–Rand is not responsible for customer modification of tools for applications on which Ingersoll–Rand was not consulted.

IMPORTANT SAFETY INFORMATION ENCLOSED.

READ THIS MANUAL BEFORE OPERATING TOOL.

IT IS THE RESPONSIBILITY OF THE EMPLOYER TO PLACE THE INFORMATION

IN THIS MANUAL INTO THE HANDS OF THE OPERATOR.

FAILURE TO OBSERVE THE FOLLOWING WARNINGS COULD RESULT IN INJURY.

PLACING TOOL IN SERVICE

• Always operate, inspect and maintain this tool in accordance with American National Standards Institute Safety Code for Portable Air Tools (ANSI B186.1).

• For safety, top performance, and maximum durability of parts, operate this tool at 90 psig (6.2 bar/620 kPa) maximum air pressure at the inlet with 3/8” (10 mm) inside diameter air supply hose.

• Always turn off the air supply and disconnect the air supply hose before installing, removing or adjusting any accessory on this tool, or before performing any maintenance on this tool.

• Do not use damaged, frayed or deteriorated air hoses and fittings.

• Be sure all hoses and fittings are the correct size and are tightly secured. See Dwg. TPD905–1 for a typical piping arrangement.

• Always use clean, dry air at 90 psig maximum air pressure. Dust, corrosive fumes and/or excessive moisture can ruin the motor of an air tool.

• Do not lubricate tools with flammable or volatile liquids such as kerosene, diesel or jet fuel.

• Do not remove any labels. Replace any damaged label.

USING THE TOOL

• Always wear eye protection when operating or performing maintenance on this tool.

• Always wear hearing protection when operating this tool.

• Keep hands, loose clothing and long hair away from rotating end of tool.

• Anticipate and be alert for sudden changes in motion during start up and operation of any power tool.

• Keep body stance balanced and firm. Do not overreach when operating this tool. High reaction torques can occur at or below the recommended air pressure.

• Tool shaft may continue to rotate briefly after throttle is released.

• Air powered tools can vibrate in use. Vibration, repetitive motions or uncomfortable positions may be harmful to your hands and arms. Stop using any tool if discomfort, tingling feeling or pain occurs. Seek medical advice before resuming use.

• Use accessories recommended by Ingersoll–Rand.

• Use only impact sockets and accessories. Do not use

hand (chrome) sockets or accessories.

• This tool is not designed for working in explosive atmospheres.

• This tool is not insulated against electric shock.

The use of other than genuine Ingersoll–Rand replacement parts may result in safety hazards, decreased tool performance, and increased maintenance, and may invalidate all warranties.

Repairs should be made only by authorized trained personnel. Consult your nearest Ingersoll–Rand Authorized Servicenter.

PARA FERRAMENTAS PNEUMÁTICAS DE

IMPULSO DE LÂMINAS

DUPLAS MODELOS 180PQ1, 280P E 280PQ1

AVISO

As Ferramentas Pneumáticas de Impulso Modelos 180PQ1, 280P e 280PQ1 são concebidas para uso em operações de montagem que necessitem torque consistente. Elas são adequadas idealmente para montagens de equipamento e aplicações que exijam níveis baixos de ruído.

A Ingersoll–Rand não é responsável por modificações feitas pelo cliente em ferramentas nas quais a Ingersoll–Rand não tenha sido consultada.

ADVERTÊNCIA

INFORMAÇÃO DE SEGURANÇA IMPORTANTE EM ANEXO.

LEIA ESTE MANUAL ANTES DE OPERAR A FERRAMENTA.

(6.2bar/620kPa)

AJUSTES

AJUSTE DE TORQUE

Para ajustar o torque nestas Chaves Dinamométricas de Impulsão de Lâminas Duplas, proceda da seguinte maneira:

1. Remova o Bujão do Furo de Ajuste.

2. Gire o Eixo de Comando até o Parafuso de Ajuste de Torque estar visível na abertura.

3. Usando uma chave Allen de 1,5 mm, gire o Parafuso de Ajuste no sentido horário para aumentar o torque de saída e no sentido contrário aos do ponteiros do relógio para diminuir o torque de saída. Não gire o Bujão de Óleo.

ADVERTÊNCIA

Use sempre protecção contra o ruído ao operar esta ferramenta.

ADVERTÊNCIA

Não carregue a ferramenta segurando na mangueira.

ADVERTÊNCIA

Opere com pressão do ar Máxima de 90–100 psig (6,2–6,9 bar).

2. Remova o Calço do Corpo de Borracha.

3. Usando mordentes de morsa de cobre, agarre com cuidado as pás da Capa do Mecanismo com a extremidade de saída do Eixo de Comando para baixo.

4. Usando uma chave ajustável, desparafuse o Conjunto do Corpo do Motor da Cobertura do Mecanismo. Esta é uma

rosca à esquerda, gire o Corpo do Motor no sentido horário para removê–lo.

Veja o Desenho TPD1264.

SENTIDO HORÁRIO PARA SOLTAR

ADVERTÊNCIA

Desligue sempre a alimentação de ar e desconecte a mangueira de alimentação de ar antes de instalar, remover ou ajustar qualquer acessório nesta ferramenta, ou antes de executar algum serviço de manutenção nesta ferramenta.

ADVERTÊNCIA

Não use mangueiras de ar ou adaptadores danificados, gastos ou deteriorados.

AVISO

Faça todos os ajustes finais no serviço.

4. Reponha o Bujão do Furo de Ajuste.

MUDANDO O FLUIDO DO MECANISMO

Para mudar o Fluido do Mecanismo no Mecanismo de Impulso, proceda da seguinte maneira:

1. Para o modelo 180PQ1 ou 280PQ1, use uma ponta de

prova para empurrar o Assento da Mola contra a Mola da Camisa Retentora. Enquanto a Mola for comprimida utilize uma outra ponta de prova ou chave de fenda de lâmina fina para remover o Anel de Retenção. Erga o Assento da Mola, a Mola e a Camisa de Retenção do bite para fora do Eixo de Comando e remova a Esfera de Retenção do Bite.

(Desenho TPD1264)

5. Erga para fora o motor montado da Cobertura do Mecanismo e puxe o conjunto do mecanismo para fora da capa.

6. Usando uma chave Allen de 1,5 mm, gire o Parafuso de Ajuste de Torque no sentido horário até o Parafuso parar. Gire o Parafuso no sentido contrário ao dos ponteiros do rolócio até que ele pare ou execute seis voltas completas.

AJUSTES

7. Usando uma Chave em T (Tee) fornecida no Kit da Ferramenta, (Número de Pedido 180PQ–99), remova o Bujão de Óleo e o Lacre do Bujão de Óleo.

8. Com a abertura do bujão de óleo para baixo sobre um recipiente, gire o Eixo de Comando para expelir o fluido do mecanismo.

9. Usando uma seringa e fluido do Kit de Reposição de Fluído (Número de Pediddo EQ106S–K400), encha o mecanismo com fluido fornecido no Kit. Veja Desenho TPD1265.

AVISO

NÃO SUBSTITUA POR QUALQUER OUTRO FLUIDO. Caso o fluido fornecido não for usado danos podem ocorrer à ferramenta, aumento da manutenção e diminuição do desempenho. Use somente fluido limpo nestas ferramentas.

11. Rosqueie o Bujão de Óleo com o Lacre do Bujão de Óleo no mecanismo até que ele esteja apertado.

12. Usando uma chave Allen de 1,5 mm, gire o Parafuso de Ajuste de Torque no sentido horário até o Parafuso parar. Esta é a posição de máximo torque.

13. Limpe a parte externa do mecanismo a seco e limpe e remova o Bujão da Câmara de Óleo. Usando uma seringa, retire 0,25 cc de fluído dos modelos 180PQ1 e 0,3 cc dos modelos 280P e 280PQ1.

14. Instale o Bujão da Câmara de Óleo e aperte–o com um torque de 2,3 a 2,8 Nm (20 a 25 pol–lb).

15. Insira o conjunto do mecanismo, com a extremidade de saída liderando, na Capa do Mecanismo grampeada nas garras da morsa.

16. Insira a extremidade hexagonal do eixo do rotor no recesso na traseira do Eixo de Comando e rosqueie o Corpo do Motor montado na Capa do Mecanismo. Esta é uma rosca à esquerda. Gire o Corpo no sentido contrário ao do dos ponteiros do relógio para apertá–lo. Veja Desenho TPD1266.

SENTIDO CONTRÁRIO AO DOS PONTEIROS DO RELÓGIO PARA APERTAR

MAINTENANCE SECTION

Always wear eye protection when operating or performing maintenance on this tool.

Always turn off the air supply and disconnect the air supply hose before installing, removing or adjusting any accessory on this tool or before performing any maintenance on this tool.

CHANGING THE MECHANISM FLUID

To change the Mechanism Fluid in the Impulse Mechanism, proceed as follows:

1. For model 180PQ1 or 280PQ1, use a pointed probe

to to push the Spring Seat (75) against the Retaining Sleeve Spring (74). While the Spring is compressed, use another pointed probe or thin blade screwdriver to remove the Retaining Ring (76). Lift the Spring Seat, Spring and Bit Retaining Sleeve (73) off the Drive Shaft (50) and remove the Bit Retaining Ball (72).
