GENERAL SAFETY RULES

CAUTION : FAILURE TO FOLLOW THESE PRECAUTIONS COULD RESULT IN PERSONAL INJURY, AND/OR DAMAGE TO PROPERTY. PLEASE KEEP THESE INSTRUCTIONS IN A SAFE PLACE FOR FUTURE REFERENCE.

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 the 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 jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
5. 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.

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.
13. Use the power tool and accessories in accordance with these instructions and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed. 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. Use of a cable suitable for outdoor use reduces the risk of electric shock.

BELT/DISC SANDER SAFETY

1. ALWAYS wear a dust mask when using this machine. Be aware that harmful or toxic dusts could be produced when sanding some woods.
2. ALWAYS use the table to support the workpiece.
3. ALWAYS check to ensure the attachments are secure before starting.
4. ALWAYS maintain a suitable clearance between table and sanding belt.
5. ALWAYS hold the workpiece firmly so that it cannot be torn from your hands
6. ALWAYS ensure that nails or foreign objects have been removed from a workpiece beforehand. Nails etc. will destroy the belt.
7. NEVER sand pieces which cannot be held firmly by hand.

GRINDING STONE SAFETY

1. Check the speed of the grindstone before fitting to your grinder. NEVER use a stone with a rpm speed less than the rpm speed of your grinder.
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 it’s 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. NEVER use a damaged grinding stone. Inspect the stone before each use for chips, cracks or excess 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.
9. 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.
10. 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.

BENCH GRINDER SAFETY WARNINGS

1. Hold aNY tool or blade being sharpened firmly to prevent loss of control.
2. NEVER install a 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 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 authorised service center. Following this rule will reduce the risk of electric shock, fire or serious injury.

USING THE MACHINE FOR GRINDING

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

SETTING THE SPARK DEFLECTOR AND EYE SHIELD

1. Slacken the spark arrestor securing screw and position the arrester so that the bottom edge is adjacent to the wheel, with a clearance of approximately 2 mm. Tighten the screw to secure in position.

2. Secure the eye shield in position.
   The eye shield should be a tight enough fit on its mounting that it does not move under operational vibration, but loose enough so that it may easily be positioned by hand.

3. Check the grinding wheel guard and make any adjustments necessary before use.

SETTING THE TOOLREST

1. Slacken the tool rest securing knob and position the rest so that it is adjacent to the grinding wheel with a clearance of approximately 2 mm. Tighten the bolt to secure in position.
   • NEVER attempt to grind a piece of metal that is thinner than the gap between the tool rest and the grinding wheel.
   

USING THE GRINDING WHEEL

WARNING : APPLYING EXCESSIVE FORCE TO THE GRINDING WHEEL CAN BE DANGEROUS AND COULD CAUSE DAMAGE TO THE MACHINE. NEVER ATTEMPT TO USE THE SIDE OF THE GRINDING WHEEL.

1. Turn the grinding wheel by hand to ensure it is free, then switch ON by pushing the switch so that the “I“is depressed. To switch OFF push the switch so that the “0” is depressed.
2. Press the workpiece to be ground, evenly onto the grinding stone and move the workpiece sideways across the stone. Make sure that at least half the width of the workpiece always presses on the grinding stone at any time to avoid damage to the stone.
3. Allow the machine to do the work. DO NOT apply excessive pressure on the tool when grinding or to the belt when sanding
4. The clearance between the grinding wheel and tool rest should be maintained. If the clearance gap is greater than the thickness of the metal being ground there is a danger that the force of grinding will cause the work piece to be pulled into the gap and is potentially dangerous. An incorrect gap could also cause “chatter” which could result in damage to the wheel.
5. The plastic tray can be used to contain coolant for use during grinding.

SHARPENING TIPS

SCISSORS
If possible, take the scissors apart to make the sharpening operation easier and safer. Remove material only from the outside surface and work from the handle end of the blade towards the tip.

KNIVES
Remove metal equally from both faces, working from the handle end of the blade towards the tip.

USING THE BUILT IN LIGHT
The built in light will come on whenever the machine is switched on.
The arm can be adjusted to set the light in the most suitable position.

USING THE MACHINE FOR SANDING

WARNING : ENSURE THAT THE WORKING POSITION ADOPTED DOES NOT CAUSE OPERATOR FATIGUE WHICH MAY LEAD TO LOSS OF CONTROL OF THE WORKPIECE BEING SANDED.
WARNING : THE SANDING BELT WILL CONTINUE TO ROTATE BRIEFLY AFTER THE OFF SWITCH HAS BEEN PRESSED.

SETTING THE SANDER WORK REST

Slacken the wingnut that secures the work rest in place and position the rest so that it is adjacent to the belt edge and at 90 degrees to the belts surface with approximately 2 mm clearance. Tighten the wingnut to secure in position.

USING THE SANDING BELT

1. Switch the motor ON by pushing the switch so that the “I” is depressed, and allow the machine to reach full speed. To switch the motor OFF push the switch so that the “0” is depressed.
2. Hold the workpiece firmly on the work rest and apply slight pressure to the sanding belt, allowing the machine to do the work.

MAINTENANCE

GENERAL MAINTENANCE

Make sure 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 bench grinder unless you are qualified to do so. The drive motor and bearings are sealed units and require no regular maintenance. Should you require assistance, contact your service agent.
The grinding stone will wear down with use and may well go out of true. Use the dressing wheel or stone grader to correct the trueness and to remove worn, glazed areas from the stone.
The stone will have a finite life expectancy dependant upon the nature of the work being done. Periodically, make a note of the wheel diameter and replace the (150mm dia) wheel if it reduces to as little as (130mm) in diameter.

INSTALLING A NEW GRINDING WHEEL

WARNING : NEVER OPERATE THE GRINDING WHEEL WITHOUT THE GUARD FITTED IN POSITION.

To renew or change the grinding wheels, proceed as follows.

1. Switch off and un-plug from power supply. Remove the grinding wheel cover by loosening the three retaining screws and twisting the guard anti-clockwise to disengage it from the machine.

2. Hold or jam the sanding belt roller to stop the drive shaft rotating and remove the nut and retaining disc securing the grinding wheel, remembering that the nut has a LEFT HAND THREAD.

3. Remove the used wheel and replace with a new one.
   • DO NOT overtighten the wheel retaining nut.

4. Refit the grinding wheel cover and re-adjust the tool rest and spark arrester brackets to suit the new wheel.

5. 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 mis-shapen. To correct these defects, a grinding stone dresser is supplied with the machine. Further items are available from your CLARKE dealer.

• ET125 Grinding Wheel Dresser – Part No:1700225
• 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.
3. When the abrasive wheel starts to become clogged with debris, use the dresser tool supplied to clean (dress) it

CHANGING THE SANDING BELT

To renew or change the sanding belt proceed as follows:

1. Unplug from the power supply. Remove the sander side cover by unscrewing the securing screw.

2. Slacken the top roller securing wingnut, allowing the top roller to move slightly off its axis as shown.

3. Slide the belt off and replace with a new one, ensuring it lies centrally on the top and bottom rollers

4. Retighten the top roller securing wingnut till it becomes firm but NOT too tight. The belt should now be fairly taught and positioned centrally on the rollers.
   
   IMPORTANT: The belt needs just enough tension to ensure that it does not slip on the rollers whilst under load, however too much tension will shorten the working life of the belt and the machine.

5. Replace the sanding belt cover.

6. Rotate the belt by hand whilst screwing the Tracking Adjustment screw in or out to ensure the belt runs centrally on the rollers. Turn the screw anticlockwise to move the belt outwards (towards the outer cover), or clockwise to move inwards.

7. When satisfied, plug the machine into the power supply and switch on.
   Make fine adjustments with the Tracking Adjustment screw if necessary.

CLEANING & STORAGE

Clean the exterior of 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 clear. If not bolted to a workbench, store the grinder in a clean, dry location, out of reach of children.
