1. KEEP GUARDS IN PLACE and check they are not damaged. 2. REMOVE ADJUSTING KEYS AND WRENCHES. Make a habit of checking to see
that all adjusting keys and wrenches are removed from the machine before turning it on.
3. KEEP WORK AREA CLEAN. Cluttered areas and work benches invite
accidents.
4. DO NOT USE IN A DANGEROUS ENVIRONMENT. Do not use any power tools in
damp or wet areas, or expose them to rain. Keep work area well lit.
5. KEEP CHILDREN AWAY. All visitors, but in particular children, should be kept at
a safe distance away from the work area.
6. MAKE YOUR WORKSHOP CHILDPROOF with padlocks, master switches, or by
removing starter keys.
7. DO NOT FORCE YOUR BENCH GRINDER. It will do a better and safer job if used
at the rate for which it was designed.

8. USE THE RIGHT TOOL. Do not force your tool or attachment to do a job for
which it was not designed.
9. WEAR THE PROPER APPAREL. No loose clothing, gloves, neckties, rings,
bracelets, or any other jewellery which might get caught in moving parts. Non-slip footwear is recommended. Wear protective hair covering to contain long hair.
10. ALWAYS USE SAFETY GLASSES. Everyday glasses only have impact resistant
lenses, they are not safety glasses. Also use a face mask if grinding operation is generating a lot of dust.
11. DO NOT OVERREACH. Keep a firm footing and proper balance at all times. 12. DISCONNECT FROM THE MAINS before attempting any kind of service work or
adjustment or when changing accessories such as grinding wheels.
13. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest
performance.
14. REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure switch is in the OFF
position before plugging in.
15. CHECK FOR DAMAGED PARTS. Before further use of tool, any damaged part
should be carefully inspected and checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, mounting, and any other damage that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced. If in any doubt contact your local dealer. SPECIAL SAFETY RULES FOR BENCH GRINDERS
1. Replace a cracked wheel immediately. 2. Always use guards and eyeshield. 3. Do not overtighten wheel nut. 4. Adjust distance between wheel and tool rest to maintain 1/16” (1.6mm) or less
separation as the diameter of the wheel will decrease with use.
5. Use a grinding wheel suitable for the speed of grinder. (See technical data). 6. Stand slightly to one side of the bench grinder during operation, not facing
directly in front.
7. One minute of free rotation is necessary for a new grinding wheel: should the
new grinding wheel be faulty and break, it will happen within the first minute of operation.
8. Do not remove the wheel guard except when changing a worn wheel. 9. Do not use the grinding wheel for any kind of cutting. 10. Do not over stress the grinding wheel. 11. Use a file to remove burrs from the grinding wheel. 12. NEVER LEAVE A GRINDER RUNNING UNATTENDED. TURN POWER OFF. Do not
leave tool until it comes to a complete stop.

MAINTENANCE
(A) 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 to suit operator. The Spark Arrester brackets should be adjusted so that they are as close as possible to the wheel without impairing the wheels rotation. (B) 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 mounting screws 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 adjustment is complete. (C) CHANGING THE GRINDING WHEEL To renew or change the grinding wheels, follow the steps given below. 1. Switch off and un-plug from mains power supply. Disassemble outer covers,
left or right, by removing the three cover retaining nuts, bolts and washers.
2. Slacken the Spark Arrester bracket and Tool Rest mounting screws, and pull
the bracket and Tool Rest away from the wheel.
3. 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.
4. Take off the used wheel and replace with the new one, ensuring:
a. the paper blotters are in place either side of the wheel. b. that there is a good balanced rotation of the grinding wheel, and c. you do not overtighten the wheel nut.
5. Readjust the Tool Rest and Spark Arrester Brackets as described above. 6. Switch ON the machine and allow it to rotate freely for at least one minute.

ASSEMBLY
1. Fix the Tool Rests, with the screws and washers provided, in the manner 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, in the manner shown in Fig.2. NOTE: Before fully tightening the screws, each bracket should be adjusted by sliding it as close to the grinding wheels as possible, without impairing the wheels rotation. As the wheel wears down with use, it will be necessary to re- adjust the Spark Arrester brackets accordingly.
3. Assemble the Eye Shields on to the Spark Arrester brackets using the nuts, bolts
and washers supplied, in the manner shown in Fig.3. The angle for the Eye Shields can be adjusted to suit the operator.
4. We recommend that your Clarke 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.

ELECTRICAL CONNECTIONS
Connect the mains lead to a standard, 240 volt (50Hz) electrical supply through a fused good quality (rubber preferred)13 amp BS 1363 plug, or a suitable fused isolator switch.
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in the mains lead are coloured in accordance with the following code:
Green & Yellow —- Earth Blue —- Neutral Brown —- Live
As the colours of the flexible cord of this appliance may not correspond with the coloured markings identifying terminals in your plug, proceed as follows:
Connect GREEN & YELLOW cord to terminal marked with a letter “E” or Earth symbol ‘ ’ or coloured GREEN or GREEN & YELLOW. Connect BROWN cord to terminal marked letter “L” or coloured RED. Connect BLUE cord to terminal marked letter “N” or coloured BLACK.
We recommend that this unit is fitted with a Residual Current Device (RCD). FUSE RATING The fuse in the plug for this appliance must be rated at 5 amps. IMPORTANT NOTICE If this appliance is fitted with a plug which is moulded onto the electric cable (i.e. non rewirable) please note: 1. This plug must be thrown away if it is cut from the electric cable. There is a
danger of electric shock if it is subsequently inserted in a socket outlet.
2. Never use the plug without the fuse cover fitted. 3. Should you wish to replace a detachable fuse carrier, ensure that the correct
re-placement is used (as indicated by marking or colour code).
