Instructions
Grinding Wheel use
Grinding Wheels are a safe tool when used as they are designed to be.
However, when machines are used incorrectly or without caution, damage to the wheel can result.
Be sure to follow the instructions below to ensure safe operation.
◎Instructions
- The three main rules of wheel handling that should be followed are “カジノシークレット vプリカ roll ”, “カジノシークレット vプリカ drop” and “カジノシークレット vプリカ bump.”
Wheels カジノシークレット vプリカ stored in dry locations and on shelves or similar safe locations. - Before installing in a machine, a visual inspection andring test カジノシークレット vプリカ performed to ensure it has no cracked, split or chipped areas.
- Ensure that the maximum speed and size indicated on the wheel correspond to the machine.
- Flanges カジノシークレット vプリカ placed with the outer diameter and contact width equal on either side, and correct ones カジノシークレット vプリカ used.
- Use theblotters attached to the wheels. Use equipment with flange diameters larger than the blotters, and without dirt or cracks.
- Balance using a balance weight.
- Ensure a gap of 3 mm or less between the wheel and workpiece rest and a gap of 3 to 10 mm between the wheel and the adjustable tangue.
- Mountedwheels (points) カジノシークレット vプリカ used with wheel axle lengths of 13 mm after mounting as standard.
- A proper wheel cover that covers at least half the wheel should always be used.
- Wheels カジノシークレット vプリカ test-operated for at least one minute beforeaplying workon the day of operation, and at least three minutes after replacing a wheel.
Portable grinders カジノシークレット vプリカ test-operated in a safe location. - Safety equipment including protective goggles and dust-proof masks カジノシークレット vプリカ worn during operation.
- In order to prevent the wheel from becoming imbalanced, wheel rotation カジノシークレット vプリカ stopped after the coolant has been stopped and completely shaken off.
- Flying sparks カジノシークレット vプリカ blocked with a screen or similar equipment.
- Steps to prevent particulates カジノシークレット vプリカ taken and sufficient ventilation カジノシークレット vプリカ provided in order to prevent respiratory illness.
×Precautions
- カジノシークレット vプリカ drop or bump wheels and カジノシークレット vプリカ use wheels shown to have flaws upon inspection.
- If the wheel’s hole diameter does not conform to the machine, カジノシークレット vプリカ force it on or modify the hole.
- カジノシークレット vプリカ use the wheel at a speed that exceeds the maximum speed indicated on the wheel.
- カジノシークレット vプリカ use a flange with deformations, scratches, dirt or rust on the wheel contact surface. カジノシークレット vプリカ use a flange without under cut. カジノシークレット vプリカ use a flange (steel disk wheel) with run-off with a nut-mounted wheel.
- When mounting a wheel on a flange, カジノシークレット vプリカ tighten the nut too tightly.
- カジノシークレット vプリカ use the side surface of wheels unless they are designed to have their side surfaces used.
- カジノシークレット vプリカ rotate the wheel before attaching the wheel cover.
- カジノシークレット vプリカ forcibly push workpieces onto wheels. カジノシークレット vプリカ forcibly push wheels onto workpieces.
- カジノシークレット vプリカ touch the wheel directly while it is rotating.
- When test-operating a wheel, カジノシークレット vプリカ stand in front of the wheel in the direction of rotation.
- When operating a portable grinder, カジノシークレット vプリカ place the grinder on a table, the floor or a workpiece until the wheel has completely stopped rotating.
- カジノシークレット vプリカ operate wheels in locations that are susceptible to fire or explosions.
- カジノシークレット vプリカ come within range of flying sparks.
- Operatorswho have notbeentrainedfor safetyshould not replace wheelsor operate grinding machines.
