GENERAL SAFETY RULES
WORK ENVIRONMENT
1. Keep the work area clean and tidy.
2. Dress appropriately - do not wear loose clothing or jewellery. Tie long hair
out of the way.
3. Keep children and visitors away - do not let children handle the 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 - Keep your proper footing and balance at all times.
3. Never use oxygen, carbon dioxide, combustible gasses 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 components by applying excessive force.
CAUTION: FAILURE TO FOLLOW THESE PRECAUTIONS COULD RESULT IN
PERSONAL INJURY, AND/OR DAMAGE TO PROPERTY.

COMPRESSED AIRLINE REQUIREMENTS
• Use only clean, dry, regulated compressed air.
• 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.
• Ensure that air pressure does not exceed that stated in the
specification for the tool or regulator. Higher pressures and
contaminated air will shorten the life of the air tool due to faster
wear and is a possible safety hazard.
IMPORTANT! Any airline lubricator required for motorised air tools must be fitted
downstream of the filter/regulator.
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.

INSTALLATION
MOUNTING THE UNIT
This filter/regulator is supplied with a
bracket for mounting it to a wall or
any suitable framework.
It should ideally be connected to a
fixed airline or be mounted at the
outlet of the compressor.
1. Secure the bracket to the
regulator using the locking ring.
• Airflow direction is marked with
an arrow on the regulator body.
2. Ensure sufficient free space above the regulator for future adjustments.
3. Ensure the compressor is turned off when making connections. Take care
not to overtighten when connecting the airline unions.
4. After connection, turn on the air supply and check for air leaks. Rectify any
found before starting work.
• PTFE tape may be useful for sealing threaded connections.
SETTING
The adjustment knob is of the locking type.
1. Adjust the delivery air pressure as required, by pulling the regulator cap
upwards and then twisting clockwise to increase or anti-clockwise to
reduce the outlet pressure as displayed on the gauge, When the pressure is
correct, press the cap back to lock and retain the setting.
• Turning the adjustment knob clockwise increases the pressure as
displayed by the gauge. Turning counter clockwise will reduce the
pressure.
• + and - are marked on the knob.
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.

CARE AND MAINTENANCE
A build-up of moisture in the air compressor will accelerate wear and corrosion
in airline tools. Ensure any moisture is drained from the compressor routinely
and that any in-line filter is kept clean.
The filter bowl will require draining by
manually pulling the valve open.
Ensure the water level always remains
below the baffle inside the bowl.
With use, the filter will become
sufficiently blocked that the air
throughput can become severely
diminished. It should be removed and
cleaned as follows:
1. Shut off the air compressor and
vent any remaining air from the
airline.
2. Remove the outer bowl cover by
pulling the spring loaded catch
down, then push up and twist the bowl 45 deg, before pulling the bowl
from the body (against any frictional resistance from the O-ring).
3. Gently clean the filter and body
using dishwashing liquid and allow
to dry before re-assembly. Blow
out internal passages in the body
with compressed air.
Your filter/regulator has been
designed to give long and trouble
free service. If, however, having
followed the instructions in this booklet
carefully, you encounter problems,
take the unit to your local CLARKE
dealer.
