cause a hazard if damaged by action of the blades.

USE OF THE SCRAPING TOOL

1. Ensure that the workpiece is kept at waist height where possible. NEVER use

the tool between the legs whilst sitting on the floor.

2. ALWAYS allow the tool to run up to full operating speed before applying it

to the job.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

3. Use clamps, or vices to hold a loose workpiece. Failure to secure the

workpiece could result in personal injury.

4. Inspect the blades before use. DO NOT use if damaged.

5. ALWAYS wear a face mask when using the tool as protection from

airbourne particles. Avoid disturbing existing dust and minimise the

scattering of dust in the workplace environment. Take steps to control the

dust at the point of emission.

TRANSPORTATION AND STORAGE

1. NEVER carry the tool by the air supply hose.

2. NEVER carry the tool with your finger on the trigger.

3. When not in use the tool should be disconnected from the air supply and

stored in a dry place out of the reach of children.

4. Avoid storing the tool in environments where the temperature is below 0oC.

COMPRESSED AIR REQUIREMENTS

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

Air compressors used with the tool must comply with the appropriate

European Community Safety Directives.

A build-up of moisture or oil in the air compressor will accelerate wear and

corrosion in the tool. ensure any moisture is drained from the compressor daily

and the inlet filter is kept clean.

If an unusually long air hose is required, (over 8 metre by up to 15 psi to

maintain air pressure at the tools), the line pressure or the hose inside diameter

may need to be increased.

For optimum performance it is recommended that a 3/8” I/D airline hose is

used.

A typical air line layout is shown below. If an automatic in-line filter/regulator is

used, it will keep the tool in good condition, but 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.

WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU

ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF AIR

COMPRESSORS AND COMPRESSED AIR SUPPLIES.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

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

the tool.

Never exceed the maximum operating pressure for the tool. It is

recommended that air pressure to this tool does not exceed 90 psi at the tool

when running. Higher pressures and unclean air will shorten the life of the tool

due to faster wear and is a possible safety hazard.

Check air hose for wear of damage before use.

BEFORE USE

NOTE: Ensure the compressor is turned off and remove the travel plug

from the inlet connection of the air tool.

1. If required, connect an in-line mini

oiler to the tool.

• A mini oiler helps to prolong the

life of the air tool.

2. Connect a suitable hose to the air

inlet as shown by screwing in the

male connector as shown.

3. Connect the other end of the hose

to the compressor.

4. Run the compressor at low pressure and check for leaks.

5. If a mini-oiler is not being used, run a few drops of oil through the tool

before use. It can be entered through the air inlet or via the hose at the

nearest connection to the air supply.

Your air tool is now ready for use. You can fit a whip hose with a quick fit

coupling if required (available from your Clarke dealer).

FITTING THE BLADES

CAUTION: THE BLADES ARE SHARP AND MAY CUT YOU IF BADLY HANDLED.

TAKE CARE DURING BLADE INSTALLATION AND REMOVAL.

1. Disconnect the air scraper

from the air supply and

squeeze the trigger lever (C) to

release any residual air.

2. Choose the blade that is

appropriate for the task.

3. Loosen both cap head screws (A)

with a hex key. Remove the

screws by hand.

WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU

ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF AIR

COMPRESSORS AND COMPRESSED AIR SUPPLIES.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

4. Remove the current blade by sliding it out of the blade holder (B). Be

careful of the sharp edge.

5. Hold the blade only by the flat surfaces. Insert the selected blade into the

blade holder's slot and align the blade bolt holes with the screw holes.

Make sure the bevel is facing upward (same facing as the screws).

6. Insert a screw into a screw hole and hand-tighten. Repeat with the second

screw. You may need to shift the blade if the bolt holes are not aligned to

allow the screw to enter the bottom half of the blade holder. Tighten with

the hex key. DO NOT overtighten.

7. Reconnect the air hose and start the compressor.

8. Test the air scraper without load to ensure the blade is secure. Point the

blade at an unoccupied spot in case the blade is ejected.

OPERATION

1. Set up the compressor and re-set

the air pressure to the scraper.

2. Squeeze the trigger to start the

tool and the blade will vibrate.

3. Increase or decrease the blows/

minute by adjusting the airflow

regulator.

4. Place the blade firmly at an angle

between the surface and the

material you want to remove.

Slowly push forward so the blade slides over the surface while separating

the unwanted material.

5. Release the trigger to stop the tool. Brush off all debris and resume scraping

until the task is complete.

SCRAPING TIPS

• DO NOT use excess pressure on the blade. Let the tool do the work.

• Allow the blade to reach working speed

• Avoid overloading the scraper If it becomes hot during use. Stop

work for a few minutes while it cools down.

DISCONNECTING THE AIR SUPPLY

1. DO NOT disconnect the air supply hose until the compressor has been shut

down and the compressed air released.

2. Refer to the compressor instruction manual for the procedure to shut down

and release the compressed air.

3. Once the pressure has been released, disconnect the air supply hose from

the tool.

CARE AND MAINTENANCE

DAILY

1. Before use, drain water from the air tank, air line and compressor.

2. Pour a few drops of CLARKE airline oil, into the air inlet. This should be

carried out regardless of whether or not an in-line mini oiler is used. If an in-

line mini oiler is not used, this procedure should be repeated after every

two to three hours of use.

CLEANING

1. Keep the body of the tool clean and free from debris.

2. Grit or gum deposits inside the tool

may also reduce its efficiency. This

condition can be corrected by

cleaning out the air strainer and

flushing out the tool with gum

solvent or oil, or failing this, the

motor may require dismantling.

This is better left to your CLARKE

dealer.

3. Periodically, check the air inlet

strainer for blockage and clean if

necessary.

WARNING: MAKE SURE THAT THE AIR TOOL IS DISCONNECTED FROM THE

AIR SUPPLY BEFORE STARTING ANY CLEANING OR MAINTENANCE

PROCEDURES.
