BEFORE USE

FITTING THE TOOL SUPPORT

1. Insert the tool support into the two mounting holes at the top of the grinder as shown.
   • The tool support can be used to support the grinding jigs/ clamps, a trueing or dressing tool, or as a tool or hand rest when working without jigs.

VERTICAL GRINDING/HONING

1. Adjust the tool support to the desired height, before tightening the two knobs to secure it in position.

HORIZONTAL GRINDING

1. Attach the tool support by inserting into the two mounting holes located on the rear of the grinder. Adjust to the desired height, before tightening the two knobs to secure it as shown.

2. Plug the machine into the nearest power supply.

3. Attach the water trough beneath the grinding stone. Fill the water trough with clean water up to the cut-out on the trough.

   • The grinding stone must run in water at all times during operation and will become soaked with water.

4. Ensure the water trough is re-filled when necessary and discard any excess particles of stone which have accumulated in the water trough after extensive use.

   • Avoid pouring the residue down a sink as this mass could eventually cause a blockage in the household plumbing.

5. To start/stop the grinder, press the ON/OFF switch.
   

   • The grinder can run either forwards or backwards, selectable via a 3-position rocker switch. Press the switch ‘up’ for reverse rotation (anti-clockwise when viewed from the grinding wheel end). Press the switch ‘down’ for forward rotation (clockwise when viewed from the grinding wheel end).

6. Distribute the abrasive paste evenly onto the honing wheel with a suitable tool as shown.

7. This should be sufficient for five to ten tool honing tasks. This process should be repeated as required to ensure the long life of the honing wheel and achieve a good finish.
   

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 WHICH MAY LEAD TO LOSS OF CONTROL OF THE TOOL BEING GROUND.

WARNING: THE STONE WILL CONTINUE TO ROTATE BRIEFLY AFTER THE SWITCH HAS BEEN PRESSED.

GETTING STARTED

The tool support can be used to support the tool clamp or be used for freehand grinding of any tools such as axes, pocket knives or woodcarving chisels that will not fit into the available tool holders.

USING THE TOOL CLAMP

The tool clamp is designed for sharpening chisels and plane blades etc. When using the tool holder proceed as follows.

1. Slide the tool clamp onto the tool support.
2. Position the clamp directly above the grinding stone or honing wheel. Loosen the two knobs on the tool clamp. Insert the tool blade (bevelled end downwards) in the tool clamp, then firmly tighten the blade in position as shown.
3. Adjust the tool support so that the tool clamp is a suitable distance fromthe grinding stone or honing wheel. Loosen the two knobs on the tool clamp to adjust the tool blade so that its edge lightly touches the grinding stone or honing wheel. The correct angle will be determined by using the Angle Guide as described below.
4. Switch on the grinder and slowly move the tool clamp back and forth along the tool support to grind the tool blade. If necessary, loosen the knobs on the tool clamp to re-adjust the blade. After adjustment, check that the angle is still correct.
   

USING THE ANGLE GUIDE

1. The angle guide is used to determine the cutting edge angle of a tool. To do so, secure the tool into the tool clamp, then install the clamp to the tool support as shown.
2. With the machine switched off, hold the angle guide with the desired angle (as indicated on the angle guide) at the tool tip.
3. Adjust the height of the tool support so that the front end of the angle guide, touches the grinding stone. Make sure the angle guide continues to touch the tool tip.
4. Once the desired angle is achieved, firmly lock the tool support in place and remove the angle guide.
   

GRINDING/HONING A KNIFE BLADE

Two knife holders are supplied for sharpening knives of different lengths and stiffness. Knives will be sharpened with an equal bevel to each side of the blade as itemized on the angle guide.

When using the knife holders proceed as follows

1. Loosen the knurled screw on the knife holder. Centre the tension plate along the top edge of the knife blade then firmly tighten the knurled screw to set the knife blade in position.
2. Tighten the knob to secure the knife blade tightly before starting work.
3. Set the knife holder on the tool support and adjust the tool support bar downward so that the knife blade lightly touches the grinding stone or honing wheel at the correct angle as determined by the angle guide.
4. Turn on the sharpener and grasp the knife holder firmly. Place the holder on the tool support and slowly move the knife holder back and forth along the tool support to grind/hone the knife blade. Steady your hand against the tool support as you work. The process will be repeated for the other side after resetting the knife in the holder.
   

GRINDING TIPS

• After setting the angle, switch on the grinder and start work.
• Press the tool blade evenly onto the 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 sharpening stone at any time to avoid damage to the stone.
• Allow the stone to do the work. Do not apply excessive downward pressure on the tool when grinding.
• Make sure the level of water in the tank is adequate. Never attempt to dry grind.

HONING TIPS

• Never hone against the direction of the honing wheel, which would cause the tool to cut into the leather honing wheel surface.
• Although you can work “freehand” for the honing process, you will achieve more precise results by securing the tool with the tool clamp or tool holder, and setting the honing angle to the angle used when grinding the tool.
• Press the tool evenly onto the honing wheel near the cutting edge, and move the tool sideways across the wheel. Ensure that at least half the width of the cutting edge comes into contact with the wheel at any time to avoid damage to the wheel.
• Allow the wheel to do the honing, without applying excessive downward pressure on the tool.
• Always ensure the honing wheel is kept saturated with machine oil and abrasive paste for best results.

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 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 local Clarke service agent.

The honing wheel may develop a bump after extensive use where the glued joint in the leather covering stands proud as the leather becomes compressed. The can be corrected by sanding away the high spot with an abrasive (sandpaper) block.

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, dependant upon the nature of the work being done. Periodically, make a note of the wheel diameter and replace your 8” (200mm) dia wheel if it reduces to an little as 7”(180mm) in diameter.

INSTALLING A NEW GRINDING STONE

1. Unscrew and remove the locknut and washer that secures the stone in place.
2. Remove the old grinding stone and fit the replacement, securing it with the locknut and washer. Grasp the honing wheel to prevent the drive shaft from turning while tightening the nut.
   

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 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.

INSTALLING A NEW HONING WHEEL

1. Unscrew and remove the hand nut and washer that secures the honing wheel in place.
2. Remove the old honing wheel and fit the replacement, securing it with the hand nut and washer. Ensure the drive pin, rests in the groove in the hidden face of the honing wheel.
   

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 the cooling vents below the grinder free of debris.

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