Overview

Assembly

Inventory

The machine is supplied with the following items. If any items are missing or damaged, please contact the dealer where you purchased the product.

• 1 x Eye Guard
• 2 x Tool Rests (1x grinding/ 1 x sanding)
• 1 x Spark Deflector
• 1 x Grinding Wheel (fitted)
• 1 x Sanding Belt (fitted)
• 1 x Wheel Dresser
• 1 x Wrench

Mounting

1. Using the base of the machine as a template, mark and drill the workbench at the positions of the mounting holes in the base.
2. Bolt the bench grinder to the bench with suitable bolts, washers, and nuts (not supplied).

Grinding Wheel

1. Fix the tool rest to the bench grinder with the wingnut as shown.
   • The tool rest is adjustable and should be positioned as close as possible to the grinding wheel.
   • Ensure that the tool rest is firmly fixed and horizontal.

Spark Deflector

1. Fit the spark deflector to the grinding wheel guard using the screw and washers provided.

Eye Sheild

1. Fit the eyeshield to the grinding wheel guard using the support arm, bolt, and washers provided.

Sanding Work

1. Fit the work rest to the sanding belt guard using the plastic wingnut, nut, and washer provided.

Dressing Tool

1. Mount the dressing wheel on the bracket on top of the machine.

Use

Deflector & Eye Sheild

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 it 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.

Tool Rest

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 it in position.
2. NEVER attempt to grind a piece of metal that is thinner than the gap between the tool rest and the grinding wheel.

Wheel

1. Turn the grinding wheel by hand to ensure it is free, then switch it 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 workpiece to be pulled into the gap, which 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.

SharpeningScissor

• 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.

Built-In

• 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.

Setting

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 belt’s surface with approximately 2 mm clearance. Tighten the wingnut to secure it in position.

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.

Installation

1. Switch off and unplug from the power supply. Remove the grinding wheel cover by loosening the three retaining screws and twisting the guard anti-clockwise to Clarke 6502130 Sanding Belt Bench Grinder disengage it from the machine.
2. Hold or jam the sanding belt roller to stop the drive shaft from 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 it 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 Tone

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 Clarke 6502130 Sanding Belt Bench Grinder 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, Clarke 6502130 Sanding Belt Bench Grinder use the dresser tool supplied to clean (dress) it.

Changing 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 it with a new one, ensuring it lies centrally on the top and bottom rollers.
4. Re-tighten 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.
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 Clarke 6502130 Sanding Belt Bench Grinder and switch on. Make fine adjustments with the Tracking Adjustment screw if necessary.

Maintainance

• 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 dependent Clarke 6502130 Sanding Belt Bench Grinder 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.

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.
