WARNING!! KEEP TOOLS AND EQUIPMENT OUT OF THE REACH OF YOUNG CHILDREN Mains Powered Tools Primary Precautions These machine are supplied with a moulded 13 Amp. Plug and 3 core power cable. Before using the machine inspect the cable and the plug to make sure that neither are damaged. If any damage is visible have the machine inspected/repaired by a suitably qualified person. If it is necessary to replace the plug, it is preferable to use an unbreakable type that will resist damage on site. Only use a 13 Amp plug, and make sure the cable clamp is tightened securely. Fuse as required. If extension leads are to be used, carry out the same safety checks on them, and ensure that they are correctly rated to safely supply the current that is required for your machine.! WARNING!! If the machine is not fitted with a NVR type ON/OFF switch, always check that the machine is OFF before connecting it to the mains supply. Work Place/Environment The machine is designed for indoor operation, do not use when or where it is liable to get wet. If the machine is to be used outside and it starts to rain, stop work and move it inside. If the machine has got wet; dry it off as soon as possible, with a cloth or paper towel. Do not use 230Va.c. powered machines anywhere within a site area that is flooded or puddled, and do not trail extension cables across wet areas. Keep the machines clean; it will enable you to more easily see any damage that may have occurred. Clean the machine with a damp soapy cloth if needs be, do not use any solvents or cleaners, as these may cause damage to any plastic parts or to the electrical components. Keep the work area as uncluttered as is practical, this includes personnel as well as material. Under no circumstances should CHILDREN be allowed in work areas. 05 General Instructions for 230V Machines Work Place/Environment Continued If the machine is not permanently fixed in place it is good practice to leave the machine unplugged until work is about to commence, also make sure to unplug the machine when it is not in use, or unattended. Always disconnect by pulling on the plug body and not the cable. Once you are ready to commence work, remove any tools used in the setting operations (if any) and place safely out of the way. Re-connect the machine. Make sure you are comfortable before you start work, balanced, not reaching etc., If the work operation appears to be excessively noisy, wear ear-defenders. If you wear your hair in a long style, wearing a cap, safety helmet, hairnet, even a sweatband, will minimise the possibility of your hair being caught up in the rotating parts of the machine, likewise, consideration should be given to the removal of rings and wristwatches, if these are liable to be a snag hazard. Consideration should also be given to non-slip footwear, etc.it is NOT recommended that gloves are worn when carrying out grinding operations, there is a definite loss of touch, if the work piece gets very hot, dowse frequently in the cooling pot. If you are allowing another person to use the machine, ensure that they are suitably qualified to do so. Do not use any tools or machinery if you are under the influence of drink, drugs or prescribed medication. Do not work with abrasive tools of any description if you are tired, your attention is wandering or you are being subjected to distraction. A deep graze, a ground fingertip or worse; is not worth it! Do not use this machine within the designated safety areas of flammable liquid stores or in areas where there may be volatile gases. There are very expensive, very specialised machines for working in these areas, THIS IS NOT ONE OF THEM. Above all, OBSERVE. make sure you know what is happening around you, and USE YOUR COMMON SENSE. 06 Initial Assembly Carefully unpack the machine and all the loose items from the box. Check the contents against the What is in the box list. If any items are missing please contact our technical services department using the telephone numbers that you will find in our catalogue. Having removed all the items from the box, please dispose of your unwanted packaging responsibly. A lot of the packaging is biodegradable. Initially we suggest that you merely carry out a loose assembly of the various parts of the grinder. After assembly has been completed we will set up the various components correctly and tighten securely. Identify the Tool Rests, both by hand and size and secure them to the inside faces of the wheel covers using the coach bolts/star nuts and washers provided. (See fig 1) Tool rest Bolts/star nut Fig 1 Identify the Eye Shield/ Spark guards. These assemblies are sized to fit over the appropriate stone; identify them and fit to the hard point on the top of the stone cover part of the guard, using the M5 screws etc, provided. (See fig 2 & 3) Fig 2 Fig 3 07 Setting Up the Grinder Please read the section entitled Identification and Description of Parts, in order for you to understand the terminology that we will use, so that you may better understand the working and capability of your grinder. Keep this manual to hand for reference for any other personnel that may be required to use the grinder. Having assembled all the grinder attachments loosely, now the machine has to be set up correctly and all the attachments securely fastened. Place the grinder on a flat level surface. Position the tool rests leaving a gap of approximately one and a half millimetres between the grindstone and the rest, with the rest horizontal (preferably) tighten the star nuts securely. (See fig 4)! Remember to adjust the tool rests as the grindstones wear down. Adjust the spark guards until they are just clear of the grindstone; fasten the fixing bolts securely. (See fig 5)! Remember to adjust the spark guards as the grindstones wear down. Fig 4 Leave a gap of approximately one and a half millimetres between the grindstone and the rest Star nut Adjust the spark guards until they are just clear of the grindstone 08 Fig 5 Position the eye shields on their pivot bolts, (if necessary, nip the clamping bolt of the eye shield clamp so that the eye shields remain in place). If there is any tendency for the grinder to move, tip or tilt while it is being operated, it should be bolted down; either to the bench or to a specific stand. It is a good idea to dress new grindstones before use, to remove any possible irregularities, and ensure the stones are running concentrically. Setting Up the Grinder Carry out a final check e.g. start the machine, check it runs smoothly. On each side, check that the spark guard is adjusted down to the stone, check the gap between the tool rest and the stone is correct, check the stone is not badly deformed (rounded edges, grooved face, etc; unless you have specifically shaped the stone to these profiles)check the eye shield is correctly positioned. Have a cooling pot to hand if you need it, and remember safety goggles are a good investment. (you are only issued with one pair of eyes). Specification Code Model AHBGDL Rating Hobby Power 200W Voltage 230V Speed 2,800rpm Wheel Diameter 150mm Wheel Width 20mm & 40mm Bore 12.7mm Weight 10kg 09 Identification & Description of the Grinder Grinding machine Wheel guards Tool rests Eye shield/ spark guards ON/OFF switch Essentially a double ended motor, with a mounting base, the motor flanges mount the wheel guards. The motor base contains the On/Off NVR switch. Two formed metal guards that enclose the grinding wheels. They are each formed in three parts. The inner part is mounted onto the motor flange, The stone cover is sprung into the lip of the inner part and the outer part is located on it. The whole assembly is bolted together. There are various hard point locations that accept the fixing bolts that secure the attachments of the machine. Formed metal plates that bolt onto a hard point on the inside cover of the wheel guard. There is an elongated slot in the rest which gives adjustment along the coach bolt fixing. Clear protective shields that mount over the grindstone to afford a view of the workpiece, but offer protection for the eyes, They are mounted onto the spark guards making a complete assembly that bolts through a hard point on the upper part of the stone cover. The spark guard itself has an elongated slot to allow positioning and adjustment as the wheel diameter decreases. Their function is to contain,any material (esp. sparks) that would be tracked around the grindstone and sprayed out of the machine esp. over the hands. A NVR double button switch panel, marked I for On and O for Off. The NVR function ensures the machine will not be left in the ON condition, in the event of a power failure, and subsequent re-establishment of the supply. Hold down holes Four 8mm holes set in a matrix in the corner flanges of the chassis to enable the grinder to be bolted down to the bench or a stand. 10 Grinder Illustration & Parts Description ATBGDL Bench Grinder Work light Eye shield/spark guard Grindstone Grindstone Tool rest On Wheel guard Hold down holes Off ON/OFF switch 11 Specific Safety Precautions for Grinding Machines Do not operate your machine until it is completely assembled and installed according to the instructions. 2. If you are not familiar with the operation of grinding machines obtain advice from your supervisor or instructor or another qualified person. 3. Only use grinding wheels or attachments rated higher than 3600 rpm with a 5/8 (16mm) arbor on this machine. 4. Never use a chipped or cracked wheel. Always inspect each wheel before mounting it on the grinder. If during inspection you discover a damaged grinding wheel; replace it immediately. 5. Do not over tighten wheel nuts. 6. Always maintain a distance of 2mm or less between the wheel and the tool rest. Adjust the tool rests as the wheels decrease in size. 7. Ensure the tool rests are tightened so they cannot move while in use. 8. Never grind on a cold wheel. The grinder should always be run for at least one minute before applying work to it. 9. Never grind on the side of the wheel. Always grind on the face of the wheel only. 10. Never apply coolant directly to a grinding wheel, it may cause the bonding to fail. If the work piece becomes hot, dip it into a water pot to cool it down. 11. Hot sparks are a hazard! Never carry out grinding operations near flammable gas or liquid. 12. Always make sure the spark guards and eye shields are in place, that they are properly adjusted and secured. 13. Keep the sparks guards close to the wheels and re-adjust them as the wheels wear. 14. Ensure the soft washer and the flanges furnished with the grinder, are used to mount any attachments (grinding wheels, wire brushes, buffing wheels, etc) onto the shaft. 15. Always stand to one side of the grinder when starting the machine. 16. Avoid awkward hand positions where a sudden slip could cause the hands to come into contact with a grinding wheel, wire brush etc. 17. If the wheel requires dressing, dress only the front of the wheel, do not dress the sides. 18. Do not use any attachments that causes the machine to vibrate. If after changing grinding wheels or adding attachments, the machine does vibrate; remove the recently replaced item and change again. 19. Grinding creates heat. Do not touch the work face of the work piece until you are sure it has cooled down sufficiently. !! WARNING!! Changing a Grinding Wheel Ensure that the grinder is disconnected from the mains supply. Undo the nuts and bolts that secure the outer shell of the wheel guard to the inner shell. Remove the outer shell and place it and the nuts, bolts and washers carefully aside. (See fig 6) Be very careful that the stone cover does not spring out of its location lip on the inner cover, it can spring out with some force. (See fig 7) Fig 6 Fig 7 Loosen the nut holding the grinding wheel to the shaft. Carefully remove the nut, the plate flange and the soft washer that is clamping the grindstone in place. (See figs 8 & 9) Then, very carefully remove the grindstone from the shaft, take care that no damage or distortion is done to the bush (if one is fitted). (See fig 10) Now is a good time to clean out the interior of the wheel guard, removing any loose or compacted material that may have accumulated. Carefully inspect the new grinding wheel before it is fitted, check that there are no cracks, and there is no damage to either the front face or the edges. If required, fit the bush to the grindstone. Carefully mount the grindstone onto the shaft, reposition the soft washer and the wheel flange, replace the holding nut and tighten carefully. Do Not Overtighten. Refit the outside shell of the wheel guard and secure with its nuts and bolts. Refit the tool rest, positioning as in Setting up the grinder. Fasten securely. Fig 8 Fig 9 Nut Plate flange 13 Changing a Grinding Wheel Fig 10 Check that the spark guards and the tool rests are not touching the grindstone. Reconnect the grinder to the mains supply, give the grinder a short burst, by switching it on and off quickly. Check the grinder is not subject to any undue vibration. If the grinder does vibrate, strip it down again and check that the bush (if fitted) is correctly positioned and is the correct size for the stone and the spindle. Check the bore of the stone is correct. If these all seem correct, refit and carryout the quick burst procedure again. If the machine is still vibrating, discard the stone and replace with another one. Run up to speed normally. Leave the machine running for at least one minute before carrying out any work. Apply a workpiece and check that the spark guard is correctly positioned and that the tool rest is securely fixed. If necessary dress the new stone lightly to ensure a good face and good concentricity. 14 Dressing a Stone! If the grindstones wear unevenly, producing crests, dips or rounded edges, they should be dressed out using a suitable wheel dressing tool. (A selection of stone dressing tools are available in the Axminster catalogue.) Switch the grinder on and allow it to run for at least one minute. Rest the dressing tool on the tool rest and advance it to the stone until it touches the maximum diameter; gently move the dresser back and forth across the face of the stone until all irregularities have been removed and the edges of the stone are nice and sharp.! PLEASE NOTE This is not a procedure that can be rushed, it must be carried out slowly and steadily.
