SAFETY PRECAUTIONS

WORK ENVIRONMENT

• Keep the work area clean and tidy.

• Dress appropriately - Do not wear loose clothing or jewellery. Tie long hair

out of the way.

• Keep children and visitors away - Do not let children handle the sander.

Make sure that any other persons in the work area are dressed suitably

and are wearing eye and ear protectors.

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

• Do not fit the sander to any stand or clamping device that may damage

the tool.

GENERAL USE

• Stay alert and use common sense - do not use the sander when you are

tired or under the influence of alcohol, drugs or medication.

• Always wear eye protection when using the sander - eye protection must

provide protection from the front and the side.

• Always wear a dust mask when sanding dusty materials.

• Always wear ear protectors when using the sander.

• Do not over-reach - Keep proper footing and balance at all times.

• Never use any type of bottled gas as a source of power for the sander.

• Do not connect the air supply hose with your finger on the trigger of the

sander.

• Do not exceed the maximum pressure for the sander: 90 psi / 6.2 bar.

• Check hoses for leaks or worn condition before use and ensure that all

connections are secure.

• Do not use the sander for any other purpose than that described in this

booklet.

• Do not carry out any alterations or modifications to the sander.

• The sander should be serviced as required by your CLARKE dealer.

• Never use the sander if it is defective or operating abnormally.

• ALWAYS ensure the workpiece is firmly secured leaving both hands free to

control the sander.

• ALWAYS ensure the sander has stopped before putting it down after use.

• ALWAYS ensure that any attachments are correctly fastened before

connecting the sander to the power supply.

• Always disconnect from the air supply when:

a) Performing any maintenance.

b) The sander is not in use.

c) The sander will be left unattended.

d) Moving to another work area.

• Avoid damaging the sander for example, by applying excessive force.

• ALWAYS maintain the sander with care. Keep it clean for best and safest

performance.

• Quick change air-line couplings should not be located at the tool. They

add weight and could fail due to vibration.

• DO NOT force or misuse the sander. It will do a better and safer job at the

rate for which it was designed.

• This sander vibrates during use. Vibration may be harmful to your hands or

arms. Stop using the tool if discomfort, a tingling feeling or pain occurs and

seek medical advice before resuming use. Refer to Vibration Emissions on

page 13.

TRANSPORTATION

• Never carry the sander by the air supply hose.

• Never carry the sander with your finger on the trigger.

STORAGE

• When not in use the sander must be disconnected from the air supply and

stored in a dry place out of the reach of children (preferably in a locked

cabinet).

• Avoid storing the sander in environments where the temperature falls

below 0oC.

AIR SUPPLY REQUIREMENTS

WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU

ARE THOROUGHLY FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE

USE OF COMPRESSORS AND COMPRESSED AIR SUPPLY.

• Air compressors used with the sander must comply with the appropriate

European Community safety directives.

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

sander.

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

corrosion in the sander. 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 metres), line presure may

need to be increased.

A typical airline

arrangement is

shown on the right.

If an automatic in-

line filter/regulator/

lubricator unit is

used it will keep the

tool in good

condition but should

be regularly

checked and

topped up with oil.

IMPORTANT: If a filter/lubricator unit is not used, the sander should be

lubricated with 2 to 6 drops of oil, at least once a day or after 2 hours work,

depending upon the working environment. The oil can be inserted through

the airline connection point.

AIRLINE SAFETY

• Never exceed the maximum operating pressure for the sander. A pressure

of 90 psi with a flow of 6 cfm is required. Too high an air pressure will

shorten the life of the tool due to excessive wear.

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

pressure of the tool.

OVERVIEW

The CAT111 Orbital Sander is ideal for use in the automotive industry or any

task of smoothing wood, fibreglass or body filler. The sander features a

balanced ball-bearing design, rear exhaust & automatic throttle release. The

CAT111 sander holds standard 93 x 232mm sanding sheets which are

available from your CLARKE dealer.

Unpack and lay out the components, checking against the following list. Any

damage or deficiency should be reported to your CLARKE dealer

immediately.

• Orbital Sander

• Male screw-in adaptor

• Bottle of Airline Oil

• Operators Manual (this document)

ASSEMBLY

1. Remove the plastic blanking plug from the connection port of the sander .

2. Pour 2-3 drops of CLARKE airline oil into the air inlet. This should be done

regardless of whether or not a lubricated air supply is to be used.

3. Connect a suitable hose to

the sander as shown. Use the

screw-in adaptor supplied if

required.

4. Connect the other end of the

hose to the compressor.

(A whip hose with a quick

fit coupling is available

from your CLARKE dealer).

5. Turn on the air supply and

check for air leaks. Rectify

any found before proceding.

Your sander is now ready for

use.

DISCONNECTING THE AIR SUPPLY

1. Do not disconnect the air supply hose until the compressor has been shut

down and the compressed air released from the air line.

2. Once the pressure has been released, disconnect the airline hose from

the sander.

STORAGE

1. Store the sander safely in its box in a dry, secure environment.

2. If the sander is not to be used for longer than 24 hours, run a few drops of

CLARKE airline oil into the air inlet and run the tool for a few seconds to

ensure that the oil has been well distributed throughout the sander.

3. When storing, ensure the blanking plug is replaced at the airline

connection port once the airline has been disconnected.

OPERATING INSTRUCTIONS

IMPORTANT: Only use sanding sheets designed for use with a rectangular

orbital sander;-pre-cut sheets (93 x 232mm) are available from your

CLARKE dealer.

1 Attach a sanding sheet to the

base of the sander using the

spring-loaded clips at each end

of the base as in Fig 1.

• Ensure the sanding sheet is

correctly aligned with the sander

and pulled tight enough to avoid

any creasing.

2. Place the sander on the

workpiece and press down on

the trigger to start the sander.

3. Adjust the operating speed if

required, by twisting the air

regulator as in Fig 2.

4. Release pressure from the trigger

to stop the sander.

5. Always ensure the sander has

stopped before putting it down.

In the event that any of the above situations occurs, requiring the dismantling

and overhaul of the tool, contact your CLARKE International Service

Department on 020-8988-7400.

MAINTENANCE

WARNING! Make sure that the sander is disconnected from the air supply

before starting any cleaning or

maintenance procedures.

DAILY

• Drain water from the compressor air

tank and air-line.

• Pour a few drops of CLARKE air line

oil**, into the air inlet. This should be

carried out regardless of whether or

not an air line lubricator is used. If an

air-line lubricator is not used, this

procedure should be repeated after

every two to three hours of use.

WEEKLY

• Check the air inlet screen filter in Fig 3

and clean if necessary.

CLEANING

• Keep the body of the sander clean and free from debris. Grit or gum

deposits in the tool may reduce efficiency.

• After extensive use, remove the screen filter and flush out the sander with

gum solvent oil or an equal mixture of SAE No10 oil and paraffin. Allow to

dry before use.

SERVICING AND REPAIRS

• Major servicing and repair must be carried out by your local CLARKE

dealer.

PERFORMANCE

Please note that factors other than the tool may effect its operation and

efficiency such as reduced compressor output, excessive drain on the airline,

moisture or restrictions in the line, or the use of connectors of improper size or

poor condition which will reduce air supply.

**Clarke Air Line Oil is available from your CLARKE dealer part no. 3050825.

ACCESSORIES

A wide range of airline accessories are available including filter/regulators,

lubricators, high pressure hoses, etc. Contact your CLARKE dealer for further
