de ar antes de instalar, retirar ou ajustar qualquer
acessório desta ferramenta, ou antes de realizar
qualquer tipo de manutenção nesta ferramenta ou em
qualquer acessório.

• Não lubrifique a ferramenta com líquidos inflamáveis
ou voláteis como querosene, gasóleo ou combustível
para jactos. Utilize apenas os lubrificantes especifica­dos.

• Utilize apenas solventes de limpeza adequados para

• Não retire nenhum rótulo. Substitua os rótulos dani­ficados.

• Quando usar luvas, certifique-se de que as mesmas não
impedirão a libertação do mecanismo do regulador.

• Evite expor-se e respirar as poeiras e partículas nocivas
criadas pela utilização de ferramentas motorizadas:

Algumas poeiras criadas por operações motor­izadas de lixar, serrar, rectificar, perfurar e out­ras actividades de construção contêm produtos
químicos conhecidos por causarem cancro, mal­formações congénitas e terem efeitos nocivos na
reprodução. Alguns exemplos desses produtos
químicos são:

16 P7440 Edition 10

USANDO A FERRAMENTA (Continuado)

- chumbo de tintas à base de chumbo,

- sílica cristalina de tijolos e cimento e outros
produtos de alvenaria e

- arsénico e crómio de madeira tratada quimica­mente

Os riscos dessas exposições varia, dependendo
de com que frequência faz esse tipo de trabalho.
Para reduzir a sua exposição a esses produtos
químicos: trabalhe numa área bem ventilada e
com equipamento de segurança aprovado, como
as máscaras contra a poeira que são especial­mente projectadas para filtrar partículas
microscópicas.

• Mantenha terceiros a uma distância segura da sua
área de trabalho ou certifique-se de que os mesmos
estão a usar equipamento de protecção pessoal.

• Esta ferramenta não é concebida para trabalhar em
ambientes explosivos, incluindo os provocados por
vapores e poeira ou perto de materiais inflamáveis.

• Esta ferramenta não é isolada contra choque eléc­trico.

• Tenha em conta a possível presença de perigos enter­rados, ocultos e outros no seu ambiente de trabalho.
Não contacte ou danifique cabos, condutas, tubos ou
mangueiras que possam conter fios eléctricos, gases
explosivos ou líquidos perigosos.

• Mantenha as mãos, roupas soltas, cabelos longos e
jóias afastados da extremidade de trabalho da ferra­menta.

• As ferramentas mecânicas podem vibrar durante a uti­lização. Vibração, movimentos repetitivos ou posições
desconfortáveis podem ser nocivos às suas mãos e
braços. Pare de utilizar qualquer ferramenta se sentir
desconforto, sensação de formigueiro ou dor. Procure
assistência médica antes de reiniciar a utilização.

• Mantenha o corpo numa posição equilibrada e firme.
Não estique o corpo ao operar esta ferramenta. Esteja
preparado e alerta para mudanças súbitas no movi­mento, binários ou forças de reacção durante o
arranque e o funcionamento.

• A ferramenta e/ou acessórios podem continuar o mov­imento por um curto período depois que o regulador é
libertado.

• Para evitar o arranque acidental, certifique-se de que
a ferramenta está na posição desligada ("off") antes

de aplicar pressão de ar, evite apertar o regulador ao
transportar a ferramenta e liberte o regulador
durante a perda de ar.

• Certifique-se de que as peças de trabalho estão segu­ras. Sempre que possível, utilize grampos ou tornos
para fixar a peça de trabalho.

reacção da ferramenta.

• Quando for utilizado um dispositivo de elevação, cer­tifique-se de que está preso com segurança.

• Mantenha-se afastado do ponto de aperto entre a
barra de reacção ou punhos de apoio e qualquer
objecto fixo na área de trabalho.

• Após reparar ou substituir peças, as ferramentas com
dispositivos de desligamento automático ou de
embraiagem devem ser testadas para confirmar que o
dispositivo está a funcionar adequadamente.

LUBRICATION

Each time a Series QS Screwdriver is disassembled for
maintenance and repair or replacement of parts, lubricate
the tool as follows:

1. Coat all exposed gears with Ingersoll-Rand No. 67 Grease and work some of the Grease into the gearing of the Spindle Assembly (42).

2. Work approximately 6 to 8 cc of Ingersoll-Rand No. 28 Grease into the ball pockets, jaws, adjusting nut lock and shaft threads of the clutch mechanism.

3. Use Ingersoll-Rand No. 10 Oil to lubricate the motor. Inject approximately 1 to 2 cc of oil into the air inlet before attaching the air hose to the tool.

Therefore, the adjustment, although simple, should only be
attempted by a competent technician using the proper
equipment.

The Back Cap (6) has a small, molded stud on the end face
of the Cap nearest the Exhaust Diffuser (15). That stud
controls the radial location of the Diffuser which controls
the opening size of the exhaust ports. Take an initial
reading of the tool speed by applying a tachometer with a
convex tip to the inside of the Bit Holder (84). Using the
procedure required to activate the motor of your particular
model tool, bring the motor to maximum free speed.

After determining the actual velocity, shut off the air
supply and disconnect the air line. Use a 3/4” wrench to
loosen the Inlet Bushing. The longest slot in the Exhaust
Diffuser will contain the molded stud on the Back Cap.
Rotate the Diffuser to open the exhaust ports to increase
speed or rotate it to restrict the exhaust to reduce speed.
Being careful not to allow the Diffuser to damage the
molded stud, tighten the Inlet Bushing to 15 ft-lbs. (20
Nm) torque. Connect the air line and restore the air supply
and check the velocity again. Determine which direction
you need to rotate the Diffuser to obtain the desired speed
and then rotate it accordingly. Best results are achieved by
using gradual increments and frequent tachometer
readings. Be sure to turn off the air supply and disconnect
the line when making adjustments.

ability to precisely control speed, within certain ranges.
Setting the speed requires a tachometer.

DISASSEMBLY

General Instructions

1. Do not disassemble the tool any further than neces­sary to replace or repair damaged parts.

2. Whenever grasping a tool or part in a vise, always use leather-covered or copper-covered vice jaws to protect the surface of the part and help prevent distortion. This is particularly true of threaded members and housings.

3. Do not remove any part which is a press fit in or on a
subassembly unless the removal of that part is neces­sary for repairs or replacement.

4. Do not disassemble the tool unless you have a com­plete set of gaskets and o-rings for replacement.

Disassembly of the Tool

Each Series QS Lever Inline Screwdriver is made using
four modules or units which include a motor housing unit,
a motor unit, a clutch with bit holder unit and a combined
gearing with spindle unit. The tool can be disassembled for
repairs to each individual unit without disturbing the other
units. To separate the modules, proceed as follows:

The thread in the following step is a left hand thread.

Housing Spanner Wrench (Part No. TRH-478) in the
clutch housing slot, unscrew and remove the Clutch
Housing.

6. Push on the output end of the Bit Holder (85) to remove it from the Clutch Housing (82).

7. For Models with Lever Start, slide the Shutoff Spacer (87) and Wave Washer (87A) off the Bit Holder.

8. If the Clutch Housing Bearing (83)is worn and must be replaced, press it from the Clutch Housing.

9. Carefully remove the Clutch Assembly or Clutch Shaft (81), the Clutch Input Driver (47 or 66), the Clutch Return Spring (46 or 65), and the Push Rod (67).

10. Lightly grasp the flats of the Gear Case in leather-cov­ered or copper-covered vise jaws with the Inlet Bush­ing upward.

11. Place a 1-3/16” open end wrench on the flats of the Back Cap (6) to prevent it from rotating, and use a 3/ 4” wrench to unscrew and remove the Inlet Bushing.

12. Lift the Exhaust Diffuser (15) off the Back Cap.

13. If the Throttle Valve Spring (14) did not come out of the tool with the Inlet Bushing, use needle nose pliers to remove it and the Throttle Valve (13) from the Motor Housing (1).

14. To remove the Throttle Valve Seat, insert a hooked tool through the central opening of the Seat and pull it from the Motor Housing.

15. Using a 1/16” pilot punch, tap the Throttle Lever Pin (11) out of the Back Cap and remove the Throttle Lever (10).

16. Pull the Throttle Plunger (5) out of the Motor Hous­ing and remove the assembly from the vise.

17. Holding the assembly horizontally, remove the Back Cap, the Memory Chip (9) (if included with the tool), the Back Cap Gasket (7) and the Shutoff Valve (20) (if included with the tool).

18. If the Muffler Elements (8) need to be cleaned or replaced, pull them out of the Back Cap.

19. Grasp the flats at the inlet end of the Motor Housing
in leather-covered or coper-covered vise jaws, and
using a 1-1/16” wrench on the flats of the Motor Hous­ing, unscrew and separate the Gear Case from the
Motor Housing.

20. Set the assembled Gear Case on the workbench.

21. Remove the Motor Clamp Washer (33) and the Motor Seal (32) from the assembled motor in the Housing.

22. Tap the Motor Housing on a wood block to remove the Motor Assembly from the Housing.

Rotate the components counterclockwise to tighten them.

32. Thread the Non-Rotating Bit Finder (92) or Clutch Housing Cap (98) onto the Clutch Housing and hand tighten it between 2 and 6 ft-lbs. (3 and 8 Nm) torque.

TESTING THE TOOL

Before placing the tool back in service, test the tool in a
run down application to determine if adjustments are
necessary to satisfactorily perform the operation. Since five
interrelated adjustments can affect tool performance, only
experience, along with trial and error, can dictate which
adjustment or combination of adjustments will provide the
desired results.

The Clutch Spring (59 or 75), the clutch adjustment
procedure, the exhaust flow, the length of the Push Rod
(34) and the length of the Shutoff Valve (20) can
individually or collectively have an effect on torque and/or
speed. Always try to make adjustments before replacing or
attempting to modify components. If adjustments are
unable to provide the desired torque, it may be necessary
to install a lighter or heavier Clutch Spring.

If the tool ratchets when operated but fails to shutoff, it
may be necessary to shorten the Push Rod. Only shorten
the Push Rod in small increments. Increments between

0.005” and 0.010” (0.13 and 0.25 mm) are recommended. If

the tool stalls and does not shutoff, runs slower than
normal or has low power, the Shutoff Valve may require
lengthening. To lengthen the Shutoff Valve, grasp the stem
between two pieces of rubber or other non-slip, non­marring material and rotate the molded nut
counterclockwise. Rotating the nut one half revolution will
lengthen the Valve approximately 0.009” (0.23 mm).

Should the stem of the Valve become bent, marred, nicked
or damaged in any way during the adjustment process,
replace it.

The thread in the following step is a left-hand thread.
Rotate the component counterclockwise to tighten it.
