3. Keep children and visitors away - do not let children handle the air tools.

4. Do not operate air tools where there are flammable liquids or gases.

USE OF AIRLINE EQUIPMENT

1. Stay alert and use common sense - do not operate an air tool when you
are tired or under the influence of alcohol, drugs or medication.

2. Do not overreach when using air tools - Keep proper footing and balance
at all times.

3. Never use oxygen, carbon dioxide, combustible gases or any type of
bottled gas as a source of power for air tools.

4. Do not exceed the maximum pressure for the airline component stated in
the specification.

5. Check airline hoses for leaks or worn condition before use and ensure that
all connections are secure.

6. Keep the flexible air supply hose away from heat, oil and sharp edges.

7. Avoid damaging the components for example by applying excessive force
of any kind.

8. Always maintain any air tool to be used with care. Keep it clean for the
best and safest performance.

COMPRESSED AIRLINE REQUIREMENTS

WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF
COMPRESSORS AND A COMPRESSED AIR SUPPLY.

• Use only clean, dry, regulated compressed air as a power source.

• Air compressors must comply with the appropriate European

Community Safety Directives.

• A build-up of moisture in the air compressor will accelerate wear

and corrosion in the air tool. Ensure any moisture is drained from the
compressor daily and the airline filter is kept clean.

• If an unusually long air hose is required, (over 8 metres), the line

pressure or the hose inside diameter may need to be increased.

• The air hose must be rated at least 150% of the maximum operating

pressure of the air tool.

.

• A typical air line layout is shown above. If an automatic in-line filter &

regulator are used, they will keep the tool in good condition, and
the lubricator should be regularly checked and topped up with oil.
SAE 10 oil should be used, and the lubricator adjusted to approx 2
drops per minute.

• Never exceed the maximum operating pressure for the air tool.

Ensure that air pressure does not exceed that stated in the
specification for the tool when running. Higher pressures and
contaminated air will shorten the life of the air tool due to faster
wear and is a possible safety hazard.

INSTALLATION

WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF AIR
COMPRESSORS AND COMPRESSED AIR SYSTEMS.

1. Ensure the compressor is turned off. Before using the airline, drain water
from the air reservoir at the compressor.

2. The filter should be installed with reasonable accessibility for service
whenever possible.

3. Keep pipe or tubing lengths to a minimum with the inside clean and free of
dirt. Pipe joint compound should be used sparingly and applied only to the
male pipe — never into the female port.

4. Take care using PTFE tape to seal pipe joints — pieces have a tendency to
break off and lodge inside the unit, possibly causing malfunction.

5. Install the filter so that air flows as marked by the arrow on the filter body.

6. Installation should be downstream of the regulator but upstream of any
lubricator. The filter should be installed upstream of regulator(s),
lubricator(s), and cycling valve(s) in the air line and should be as close as
possible to the air tool being served when used as a main line filter and/or
as a final filter.

7. Install the filter vertically with the bowl drain at the bottom, ensuring there is
sufficient free space below the filter for future access.

8. Remove the blanking plugs from the connection ports and connect to the
supply and delivery hoses.

• A drain hose can be screwed to the drain port or the filter bowl

drained manually.

Your filter is now ready for use.

ACCESSORIES

A wide range of accessories is available including filter/regulators, lubricators,
high-pressure hoses (5 to 50 metres) etc. Contact your CLARKE dealer for
further information or CLARKE International Service Department.

USE AND CARE IN SERVICE

1. Let the filter run with the air supply on. Ensure that the pressure to the air
inlet of the filter from the air line does not exceed the maximum pressure
specified.

2. The filter is equipped with a manual drain. Turn the manual drain valve to
drain accumulated liquid from inside the bowl. Take care to drain the liquid
whenever necessary and always keep the liquid below the filter element.

3. The filter element should be
replaced when the pressure drop
across the element exceeds 15 psi.

4. The mechanical service indicator
shows approximately fully red
when the pressure drop across the
element reaches 15 psi. When an
excessive pressure drop across a
saturated but uncontaminated
element occurs, it may indicate
that the air tool being operated
exceeds the maximum flow rate (CFM) of the filter (See Specifications).
Refer to the maximum flow rate of your filter and make sure that the
required CFM of the air tool is within the maximum flow rate of your filter for
best tool operation.

MAINTENANCE

DISASSEMBLY

The filter can be disassembled without removal from air line.

1. Shut OFF the inlet pressure and
reduce pressure in the inlet and
outlet lines to zero.

2. Remove the bowl. Push into the
body and turn anti-clockwise.

3. Disassemble in general
accordance with the parts
illustrated. Do not remove the
drains or the service indicators
unless replacement is necessary.
Remove and replace only if they malfunction or if converting to auto drain.

CLEANING

1. The element cannot be cleaned. Clean the components with warm water
only. Do not submerge service indicator in water. Clean indicator with a
dry, clean cloth. Clean other parts with warm soapy water.

CAUTION: Some parts are made from polycarbonate which can be severely
damaged if it comes into contact with some chemicals. These include
acetone, benzene, carbon tetrachloride, ethylene di-chloride, gasolene or
synthetic fire resistant lubricants.

2. Rinse and dry the parts. Blow out internal passages with compressed air.

3. Replace any parts found to be damaged.

REASSEMBLY

1. Lubricate the o-rings, the portion of the manual drain body that contacts
the bowl, and the hole in the manual drain body that accommodates the
stem of the drain valve with o-ring grease.

2. Assemble the filter as shown on page 7. The arrows on the indicator and
body must point in same direction. Torque values are listed below.
