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 - Keep proper footing and balance at all times.
3. Never use oxygen, CO2, 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 air supply hose away from heat, oil and sharp edges.
7. Avoid damaging the component for example by applying excessive force
of any kind.
8. Always maintain the air tool with care. Keep it clean for the best and safest
performance.
COMPRESSED AIRLINE REQUIREMENTS
1. Use only clean, dry, regulated compressed air as a power source.
2. Air compressors must comply with the appropriate European Community
Safety Directives.
3. 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.
4. If an unusually long air hose is required, (over 8 metres), the line pressure or
the hose inside diameter may need to be increased.
5. The air hose must be rated at least 150% of the maximum operating
pressure of the air tool
WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF
COMPRESSORS AND COMPRESSED AIR SUPPLY.

.
6. A typical air line layout is shown above. If an automatic in-line filter/
regulator is used it will keep the tool in good condition. The lubricator
should be adjusted to approx 2 drops per minute and SAE 10 oil should be
used.
7. 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
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. 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(s) when used as a main line filter and/or as a final filter.
4. 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.
5. Do not use PTFE tape to seal pipe joints — pieces have a tendency to
break off and lodge inside the unit, possibly causing malfunction.
6. Install the filter so that air flows as marked by the arrow on the filter body.
7. Installation should be downstream of the regulator but upstream of any
lubricator.

8. Install the filter vertically with the bowl drain mechanism at the bottom.
ensuring there is sufficient free space below the filter for future access.
9. Remove the blanking plugs from the connection ports and connect to the
supply and delivery hoses.
10. A drain hose can be screwed to the drain port or the filter bowl drained
manually.
11. Your filter is now ready for use.
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 manual drain valve to drain
accumulated liquids inside the bowl. Take care to drain the liquids from the
bowl whenever necessary and always keep the liquids below the baffle.
3. The filter element should be replaced when the pressure drop across the
element exceeds 15 psi. When an excessive pressure drop across a
saturated but uncontaminated element occurs, it may indicate that the
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 air tool operation.
MAINTENANCE
DISASSEMBLY
1. The filter can be disassembled without removal from the air line.
2. Shut OFF the inlet pressure. Reduce
the pressure in inlet and outlet lines
to zero.
3. Remove the bowl. Push into the
body and turn counterclockwise.
4. Disassemble in general
accordance with the parts
illustrated on page 7. Do not
remove the drain unless
replacement is necessary. Remove

and replace only if the drain malfunctions or is being replaced with the
optional automatic drain.
CLEANING
1. Clean the polycarbonate bowl with warm water only. Clean other parts
with warm water and soap.
2. Rinse and dry all parts. Blow out internal passages in the body with clean,
dry, compressed air. Blow air through the filter element from inside to
outside to remove surface contaminants.
3. Inspect and replace any parts found to be damaged.
ASSEMBLY
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.
3. Torque items listed in the Torque Table.
4. Push the bowl into the body and turn fully clockwise
ACCESSORIES
A wide range of accessories is available including filter/regulators, lubricators,
