OVERVIEW

The items above should be supplied with the grinder. If any items are missing or damaged, please contact the Clarke 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

Except for the spark arrester and the eye shield, the bench grinder comes fully assembled. Screw the spark arrester to the bracket on the wheel cover using the single screw provided, ensuring a gap of 1.6mm is maintained between the wheel and the spark arrester, as shown in fig 2.
The following checks must be made before using the grinder or sander.

1. Ensure there is no damage to the grinder and all parts are present and correctly fitted. If any damage is apparent, contact your Clarke dealer.
2. Ensure that the tool rest, spark arrester, and sander work-rest are properly fitted and adjusted.
3. Ensure that the bench grinder is mounted securely to a suitable, stable work surface using the four bolt holes provided in the base. We recommend that your Clarke Bench Grinder is secured to your workbench before operation. Do not overtighten the mounting bolts as this could damage the plastic base.

USING THE MACHINE

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.

USING THE GRINDING WHEEL
Although the unit is supplied assembled, there is a possibility that the guards may have moved during transit. Check the guards, and make any adjustments necessary before starting the motor.

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. Allow the machine to reach full speed, then hold the tool firmly on the tool rest and apply slight pressure onto the grinding wheel, allowing the grinder to do the work.

NOTE: Never attempt to grind a piece of metal that is thinner than the gap between the tool rest and the grinding wheel (1.6 mm).
USING THE SANDING BELT

1. Position the sander work rest as required (see fig. 4) and adjust as described on page 12.
2. 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.
3. Hold the workpiece firmly on the work rest and apply slight pressure to the sanding belt, allowing the machine to do the work.

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 GRINDING WHEEL WILL CONTINUE TO ROTATE BRIEFLY AFTER THE OFF 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 machine to do the work. Do not apply excessive downward pressure on the tool when grinding.

SETTING THE EYE SHIELD AND SPARK ARRESTER
Slacken the spark arrestor securing screw and position the arrester so that the recess is adjacent to the wheel with a clearance of approximately 1.6 mm, (as shown in fig (5)). Tighten the screw to secure in position.

The plastic eye shield, attached to the spark arrester, should be tight enough so that it does not move under operational vibration, but loose enough so that it may easily be positioned by hand.
SETTING THE TOOLREST
Slacken the two tool rest securing bolts and position the rest so that it is adjacent to the grinding wheel with a clearance of approximately 1.6 mm, (as shown in fig (6)). Tighten the two bolts to secure them in position.
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 workpiece to be pulled into the gap with great force and is potentially very dangerous. An incorrect gap could also cause “chatter” which could result in damage to the wheel.
SETTING THE SANDER WORK REST
Slacken the knob 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 surface of the belt with approximately 1.6 mm clearance, as shown in fig (7). Tighten the knob to secure in position.
It is recommended that a set square is used to set the 90-degree angle. This will ensure an accurate square finish when the workpiece is placed on the rest.

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 local Clarke service agent.
The grinding 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 WHEEL

WARNING: NEVER OPERATE THE GRINDING WHEEL WITHOUT THE GUARDS FITTED IN POSITION.
To renew or change the grinding wheels, proceed as follows

1. Switch off and unplug from the power supply. Remove the grinding wheel covers by unscrewing the nuts securing the three retaining screws.

2. Remove the spark arrester bracket and eyeshield by unscrewing the single mounting screw. Slacken the tool rest mounting bolts, and pull the bracket away from the wheel.

3. Hold the sanding belt roller firmly to stop the shaft from rotating and remove the nut and flange holding the grinding wheel, remembering that the nut has a LEFT-HAND THREAD.

4. Remove the used wheel and replace it with a new one, ensuring that:
   The paper blotters and flanges are in place on either side of the wheel.
   You do not overtighten the wheel nut.

5. Refit the grinding wheel covers by using the nuts and the three retaining screws. Re-adjust the tool rest and spark arrester brackets.

6. 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.

CHANGING THE SANDING BELT

To renew or change the sanding belt, proceed as follows:

1. Unplug from the power supply. Remove the sander cover by unscrewing the three securing screws.

2. Slacken the sander work-rest securing knob, and pull the work rest away from the belt.

3. Slacken the belt tensioning nut until the belt feels loose on the rollers.

4. Slacken the top roller securing knob, allowing the top roller to move slightly off its axis as shown in fig 9a.

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

6. Retighten the top roller securing knob till it becomes firm but NOT too tight.

7. Tighten the belt tension adjuster nut until it also becomes firm. DO NOT overtighten. 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.

8. Replace the sanding belt cover, then adjust and tighten the work rest.

9. 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.

10. 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.
