WORK ENVIRONMENT

1. Keep the work area clean, tidy, and well-lit. Cluttered and dark areas invite accidents
2. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite dust or fumes.
3. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

PERSONAL SAFETY

1. Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in personal injury.
2. Avoid accidental starting. Ensure the switch is in the off position before plugging in. Plugging in power tools that have the switch on invites accidents.
3. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
4. Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
5. Gloves, manufactured to the current European safety standards should be worn when operating grinding equipment.
6. Eye protection manufactured to the current European safety standards should be worn when operating grinding equipment. Eye protectors must provide protection from flying particles from the front and the side.

GENERAL USE AND CARE OF POWER TOOLS

1. ALWAYS check for any damage or condition that could affect the grinder’s operation. Any damaged part should be properly repaired.
2. NEVER use the grinder if it is defective or operating abnormally.
3. NEVER abuse the mains cable. Never yank the cable to disconnect it from the socket. Keep the cable away from sharp edges/hot surfaces.
4. NEVER carry out any alterations or modifications to this product.
5. NEVER wipe the sharpener clean with solvents. Wipe plastic parts with a soft cloth, slightly dampened with soapy water.
6. NEVER attempt any repairs yourself. If you have a problem with this product contact your local CLARKE dealer.
7. Do not use the tool for any purpose than that described in this manual.
8. Always maintain the tool with care. Keep it clean for the best and safest performance.
9. Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate at which it was designed.
10. Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
11. Store idle tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
12. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the power tools operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

Use of the power tool for operations different from intended could result in a hazardous situation.

ELECTRICAL SAFETY

1. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use adapter plugs with earthed (grounded) power tools. Correct plugs and matching outlets will reduce the risk of electric shock.
2. Do not abuse the cable. Never use it for carrying, pulling or unplugging the power tool. Keep the cable away from heat, oil, sharp edges or moving parts. Damaged or entangled cables increase the risk of electric shock.
3. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. If operating the power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply.
4. When operating a power tool outdoors, use an extension cable suitable for outdoor use. The use of a cable suitable for outdoor use reduces the risk of electric shock.

GRINDING STONE SAFETY

1. Check the speed of the grindstone before fitting it to your grinder. Never use a stone with an rpm speed less than the rpm speed of your grinder. See specification.
2. The outside diameter and thickness of your accessories must be within the capacity rating of the power tool. The correct size accessories can be correctly guarded and controlled.
3. Never use a stone that is chipped, cracked, or damaged. Fragments from a broken or damaged grinding stone can cause serious injury. Make sure that defective stones are destroyed and not used.
4. Bonded abrasive products are breakable and shall therefore be handled with utmost care. The use of damaged or improperly mounted or used abrasive products is dangerous and can cause serious injuries.
5. Always refer to the label for specified usage and observe the safety information. Do not use for purposes other than specified.
6. Always use the correct stone for its intended task. Using the incorrect stone can cause serious injury.
7. Allow the stone and tool to do the work. Never force the workpiece against the stone as this could cause kickback and/or shatter the stone causing serious injury.
8. Do not use separate reducing bushes or adapters to adapt large hole abrasive wheels. Do not force a stone onto a machine or alter the size of the arbor hole.
9. Never use a damaged grinding stone. Inspect the stone before each use for chips, cracks or excessive wear. If the tool or accessory is dropped, inspect for damage or install a new accessory. After fitting the accessory, position yourself away from the plane of the rotating accessory and run the tool at full speed. damaged stones may break apart during this test.
10. Abrasive products shall be handled and transported with care. Abrasive products shall be stored in such a manner that they are not subjected to mechanical damage and harmful environmental influences.

BENCH GRINDER SAFETY WARNINGS

1. Hold a hand tool or blade being sharpened firmly to prevent loss of control.
2. Never install an abrasive flap wheel or sanding disc on this grinder.
3. Always replace a cracked grinding wheel immediately.
4. Never use damaged or incorrect grindstones. The stone and retaining fixtures were specially designed for your grinder, for optimum performance and safety of operation. Inspect the condition of the grinding stone before use and do not use it if any damage is found.
5. Always use the tool rests to steady the workpiece, the torque of the spinning grinding wheel may pull the workpiece from your hands.
6. ALWAYS check for damaged parts. Before further use, any part that is damaged should be carefully checked to determine if it would operate properly and perform its intended function. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool’s operation. A part that is damaged should be properly repaired or replaced at an authorized service center. Following this rule will reduce the risk of electric shock, fire or serious injury.

OVERVIEW

washer.)
D| Two Tool Rests (each with hand knobs, screws, locking  washers &  flat washers.)

The items above should be supplied with the grinder. If any items are missing or damaged, please contact the dealer where you purchased the product.
Position the machine in good light and fixed to a suitable workbench using the bolt holes in the machine base.

ASSEMBLY

1. Fix the tool rests with the locking knobs bolts and washers provided, as shown in Fig.1.
   • The tool rests are adjustable and should be positioned 1/16″ (1.6mm) from the grinding wheels. Ensure that the tool rest is firmly fixed and horizontal.

2. Assemble the spark arrester brackets onto the wheel guards, using the screws and washers provided as shown in Fig 2.

3. Before fully tightening the screws, each bracket should be adjusted by sliding it as close to the grinding wheels as possible without impairing the rotation of the wheel.
   • As the wheel wears down with use, it will be necessary to readjust the spark arrester brackets in order to maintain a gap between the spark arrester and the bracket. This gap should never be allowed to become greater than 1/8”.

4. Assemble the eye shields onto the spark arrester brackets using the nuts, bolts, and washers supplied as shown in Fig.3.
   • The angle for the eye shields can be adjusted to suit the operator We recommend that your Bench Grinder is secured to your workbench before operation using the pre-drilled holes in the base. Do not overtighten the mounting bolts as this could damage the plastic base.

USING YOUR GRINDER

WARNING: FRAGMENTS FROM A BROKEN/DETACHED GRINDING WHEEL CAN CAUSE INJURY.
WARNING: ENSURE THAT THE WORKING POSITION ADOPTED DOES NOT CAUSE OPERATOR FATIGUE MAY LEAD TO LOSS OF CONTROL OF
THE TOOL BEING GROUND.
WARNING: THE STONE WILL CONTINUE TO ROTATE BRIEFLY AFTER THE OFF THE SWITCH HAS BEEN PRESSED.

GENERAL USE

1. To start/stop the grinder, press the ON/OFF switch and start work.
2. Press the tool blade evenly onto the grinding stone and move the tool sideways across the stone. Make sure that at least half the width of the tool cutting edge comes into contact with the grinding stone at any time to avoid damage to the stone.
3. Allow the stone to do the work. Do not apply excessive downward pressure on the tool when grinding.

EYESHIELD AND SPARK ARRESTER BRACKET ADJUSTMENT
The see-through eye shields allow the user to see the operation clearly and to work precisely. The eye shields can be adjusted up and down as required. The spark arrester  brackets should be adjusted so that they are as close as possible to the grinding wheel without impairing the wheel’s rotation. IMPORTANT: Even though the eye shields are fitted, you should nevertheless wear safety goggles when operating a bench grinder.

TOOLREST ADJUSTMENT
The appropriate adjustment of the tool rests provides the operator with a correct working angle and a firm and efficient base for working. Adjustments can be made by loosening the locking knobs and moving the tool rest to within 1/16”(1.6mm) from the wheel.
Due to the wear on the grinding wheel, it will be necessary to adjust the tool rests from time to time. Always re-tighten the mounting screws once the adjustment is complete.

MAINTENANCE

GENERAL MAINTENANCE
Ensure that all components are tight and secure. Always have any damaged or worn parts repaired or replaced by qualified service personnel. Do not attempt to repair the grinder unless you are qualified to do so.
The drive motor and bearings are sealed units and require no maintenance.
Should you require assistance, contact your local Clarke service agent.
The stone will wear down with use and may well go out of true. Use a dressing wheel or stone grader to correct the trueness and to remove worn, glazed grains from the stone.
The stone will have a finite life expectancy, depending upon the nature of the work being done. Periodically, make a note of the wheel diameter and replace your (150mm) dia wheel if it reduces to as little as (130mm) in diameter.

INSTALLING A NEW GRINDING STONE
CAUTION: NEVER RE-START THE GRINDER WITHOUT THE GUARDS INSTALLED.

To renew or change the grinding wheels, proceed as follows

1. Switch off and un-plug from the power supply.

2. Disassemble outer covers, left or right, by removing the three cover retaining nuts, bolts, and washers.

3. Slacken the spark arrester bracket and tool rest mounting knobs and pull the bracket and tool rest away from the wheel.

4. Hold the grinding wheel firmly and remove the nut and flange from the shaft, noting that the left-hand wheel nut has a left-hand thread.

5. Take off the used wheel and replace it with the new one, ensuring:
   • the paper blotters are in place on either side of the wheel.
   • that there is a well-balanced rotation of the grinding wheel, and
   • you do not overtighten the wheel nut.

6.  Refit outer covers, left or right, by using the three cover retaining nuts, bolts, and washers.

7. Re-adjust the tool rest and spark arrester brackets as described above.

8. Switch the machine on and allow it to rotate freely for at least one minute.

DRESSING A NEW STONE
New grinding stones are frequently not true or in time can become grooved, glazed (built-up), out of round or otherwise misshapen. To correct these defects, a grinding stone dresser is available from your Clarke dealer.
• ET125 Grinding Wheel Dresser – Part No:1700225
• Replacement Dresser Wheel – Part No:1700230
• ET154 ½ Carat Diamond Tip Wheel Dresser – part No:1700329

1. If the grinding stone is new, allow it to spin for a minute with no load. Check that it is spinning straight and true. If not, it will require dressing before use.
2. Stand to the side of the stone and hold the dresser handle firmly. Place the dresser on the tool support so that its wheels can move freely (i.e, the exposed part of the wheel should be facing up). Run the stone and apply the dresser to the surface of the stone.

CLEANING & STORAGE
Clean the exterior the machine if required using a mild detergent or mild solvent. Never immerse the machine in water. To reduce any fire hazard, keep any cooling vents in the  grinder free of debris.
