GENERAL 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 die

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

suitably and are wearing eye and ear protectors.

• Do not operate the die grinder where there are flammable liquids or

gases.

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

• Do not fit the die grinder to any stand or clamping device that may

damage the tool.

GENERAL USE

• Stay alert and use common sense - do not operate the die grinder when

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

• Always wear eye protection when using the die grinder - eye protection

must provide protection from flying particles from the front and the side.

• When grinding, always wear an appropriate face mask or respiratory

equipment to prevent inhalation of airborne dust.

• Always wear ear protectors when using the die grinder.

• 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 die

grinder.

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

die grinder.

• Do not exceed the maximum pressure for the die grinder: 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 die grinder for any other purpose than that described in

this booklet.

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

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

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

• Always disconnect from the air supply when:

a) Performing any maintenance.

b) The grinder is not in use.

c) The grinder will be left unattended.

d) Moving to another work area.

• Avoid damaging the die grinder for example by applying excessive force.

• ALWAYS maintain the tool 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 tool. It will do a better and safer job at the

rate for which it was designed.

• This tool 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.

• ALWAYS use only the grinding tools supplied with the machine. Non-

standard attachments could become detached during use with serious

consequences.

• ALWAYS ensure that any attachments are correctly fastened before

connecting the tool to the power supply.

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

control the tool.

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

TRANSPORTATION

• Never carry the die grinder by the air supply hose.

• Never carry the die grinder with your finger on the trigger.

STORAGE

• When not in use the die grinder 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 die grinder in environments where the temperature is

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 grinder must comply with the appropriate

European Community safety directives.

• Use only clean, dry, regulated compressed air.

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

corrosion in the grinder. 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 pressure 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 grinder 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 grinder. A pressure

of 90psi with a flow of 4 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.

• Ensure the trigger is OFF before connection the tool to the air supply.

ASSEMBLY & OPERATION

CONNECTION TO THE AIRLINE

1. Remove the plastic blanking plug

from the connection port of the die

grinder as in Fig 1.

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.

NOTE: Ensure the airline is turned OFF.

3. Connect a suitable hose to the die

grinder as shown. Use the screw-in

adapter 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 die grinder is now ready for use.

INSTALLING THE COLLET

1 Select the grinding stone you

require.

Two collets of different sizes are

provided. Select whichever fits

the shank of the stone you have

chosen. (The larger collet is

probably already installed in the

grinder)

2. If the other collet is to be used,

undo the screw cap completely

and pull out the collet from the

collet seat. Replace it with the

new collet and screw the cap

loosely back on as in Fig 2.

FIG 1

FIG 2

OPERATING THE DIE GRINDER

1. Use your thumb to slide the

throttle lock forward at the

same time as squeezing the

trigger against the body of the

tool.

2. Do not use excess pressure on

the grinding stone as this will

shorten its life.

3. Release the trigger to stop the

grinder.

4. Always ensure the grinder has

stopped before putting it down.

FITTING THE GRINDING STONE

IMPORTANT: Never use chipped or

cracked grind stones.

1. Slip the shank of the chosen

stone into the collet and

tighten the screw cap finger

tight.

2. Place the smaller of the two

wrenches over the collet seat

to stop the grinder from

rotating.

3. Use the larger wrench to fully

tighten the collet and grip the

stone in position as in Fig 3.

ADJUSTING THE SPEED

1. Regulate the flow of air as

required by adjusting the air

regulator on the body of the

die grinder.

2. To adjust the speed, turn the

air regulator as required using

a screwdriver as in Fig 4. Air Regulator

FIG 3

FIG 4

FIG 5

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 air line from the die

grinder.

STORAGE

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

2. If the grinder 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 die grinder.

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

connector once the airline is disconnected.
