Grinding and Cutting Safely
Portable grinders are fast becoming the choice of many industries. But if safety guidelines are not followed, they can put you at risk of injury. Here are some crucial safety tips to keep in mind:
Most wheels are Type 27 (those with a depressed center) particularly for grinding and cutting, but those who are used for grinding alone are Type 1. These wheels are very hardy but are not necessarily immune to breakage. To help lower this risk, remember:
- Do not use a wheel to grind if it is designed only for cutting.
- Always inspect the wheel visually for signs of wear or damage before mounting on the grinder.
- If the wheel has cracks or nicks don’t use it. Don’t use it if it has been dropped as well.
- Let newly mounted wheels run without any load for one minute prior to using it.
- Don’t go over the maximum RPM as stated on the wheel.
- The wheel needs to be affixed to the grinder using the appropriate mounting flanges. Failing to do this can cause stress to the wheel. In line with this, do not excessively tighten the external mounting flange/nut.
- Don’t force the wheel onto the grinder. You should also not adjust the mounting hole size.
- Grinding on the wheel’s side should never be done.
- Don’t jam the wheel into the work.
To ensure that you are using the grinder properly and safety, make sure to do the following:
- Always use a suitably positioned wheel guard. Don’t use it without a wheel guard.
- Adjust the guard so that the least amount of wheel is exposed toward the operator.
- If the no-load speed is unknown, do not use the grinder.
- The size of the grinder should fit the wheel.
- Use both hands when using a grinder. Don’t use one without a side handle.
- Position the electric cord away from the spinning wheel.
- Wait for the wheel to come to a complete stop before laying the grinder down.
- Check if the switch is working properly. If not, don’t use the machine.
- See to it that the grinder is unplugged before removing or mounting a wheel.
- Always read the instructions manual and understand it thoroughly before using the grinder
- Before using the machine, make sure you are wearing your safety shields for the face as well as gloves. Wear hearing protection, dust mask, etc.
- Do not wear clothes that are loose. Jewelry should also be removed. Keep hair tied up to a bun (women).
- Don’t overreach. Balance and footing should be maintained at all times.
- Stay on the side of the grinder farthest from the wheel guard and the wheel.
- Other people should be at a safe distance away from where you are working.
- Keep a firm grip on the tool, and see to it that your body and arms are positioned in such a way that you can resist kickback forces in case of a jam.
- Don’t turn on the machine while carrying it at your side.
- Make sure the machine is not exposed to rain or water. It can cause electric shock.
- Take care of the power cord.
A tool and cutter grinder is necessary so your tools and cutters can work efficiently for many years. Special accessories also make your equipment more beneficial to you.
