Angle grinders are a versatile and essential tool for any DIY enthusiast or professional. Whether you’re using it for clean welds, smooth finishes, or quick cutoff work, an angle grinder can make your job easier and more efficient.
However, like any tool, it requires proper maintenance to ensure it stays in top condition. In this article, we’ll show you how to clean your angle grinder to keep it running smoothly and extend its lifespan.
From inspecting cables and hoses to cleaning the commutator, we’ll cover all the steps you need to take to keep your angle grinder in tip-top shape.
So grab your damp cloth and let’s get started!
How To Clean Angle Grinder
Before you begin cleaning your angle grinder, it’s important to inspect the cables and hoses. Look for any signs of damage such as cracks, folds, or loose connections. If you notice any damage, replace the cables or hoses before using the tool.
After each use, disconnect the power and use a brush or damp cloth to wipe off any dust or sludge. If you’re grinding wet or using a built-in misting system, make sure to tip back the grinder and wipe off the heads.
Inspect the plates and shroud, making sure all screws and bolts are in place and tightened. Check the tooling for uneven or abnormal wear, which may indicate a damaged tool holder. Inspect the tool holder and grinding head for any visible damage and replace any damaged parts.
It’s important to use manufacturer’s original parts as they are made to strict standards and are of higher quality. While pirate parts may be priced lower, they won’t last as long nor perform as well as original parts.
If your angle grinder is equipped with remote control, make sure to remove any dust and residue from the radio control unit.
After each task, use a damp cloth to wipe clean the external casing of the tool and air compressor. Blow compressed air on all components, mainly the air vents, to remove any dust and debris that might clog the cooling fan. Also, check the motor and bearings for dust and debris.
To clean the commutator on your angle grinder, first remove the carbon brushes. Once removed, expose the commutator and apply contact cleaner (for electronics) onto it. Gently wipe the commutator with a cloth. Then grab P600 sandpaper and gently rub in a circular motion. Spray it again with some contact cleaner. Put the tool back together and you’re done.
By following these simple steps, you can keep your angle grinder running smoothly and extend its lifespan. Proper maintenance is key to ensuring your tools perform at their best and keep you safe while using them.
Inspecting The Cables And Hoses
Before using your angle grinder, it’s important to inspect the cables and hoses. The first step is to look for any signs of damage such as cracks, folds, or loose connections. If you notice any damage, it’s important to replace the cables or hoses before using the tool.
To inspect the power cord, run your fingers down the cable while looking out for splits or cracks in its insulated sleeve. Make sure the cord is unplugged first. Carefully examine the grommet that attaches the power cord to the grinder. There shouldn’t be any exposed cables or wires.
It’s also important to inspect the plug for any damage such as bent pins. The label on your grinder will indicate the voltage of the machine, which should correspond to the plug fitted and the fuse.
If your angle grinder is equipped with remote control, make sure to remove any dust and residue from the radio control unit.
Regularly inspecting the cables and hoses will help you identify any potential issues before they become a safety hazard. By taking care of your angle grinder and performing regular maintenance, you can ensure that it runs smoothly and lasts for a long time.
Removing Debris And Residue From The Tool
One of the most important steps in cleaning an angle grinder is removing debris and residue from the tool. Start by disconnecting the power source and removing any abrasive or cutting discs from the tool.
Use a brush or compressed air to remove any dust or debris from the tool’s internal components. This includes the motor, bearings, and air vents. Be sure to wear protective gear such as gloves and safety glasses during this process.
Next, use a damp cloth to wipe down the external casing of the tool, paying special attention to any hard-to-reach areas. If there is any stubborn residue or buildup, use a mild detergent solution to clean it off.
If your angle grinder has a built-in misting system, make sure to clean the heads thoroughly to prevent any buildup of residue.
Inspect the plates and shroud for any debris or residue that may have accumulated during use. Use a brush or compressed air to remove any buildup, and wipe down with a damp cloth if necessary.
Finally, reassemble the tool and test it out to make sure it’s running smoothly. By regularly removing debris and residue from your angle grinder, you can ensure that it continues to perform at its best and stays in good condition for years to come.
Cleaning The Commutator
The commutator is an important component of your angle grinder that needs to be cleaned regularly. It’s responsible for transferring power from the motor to the grinding head. Over time, dust and debris can build up on the commutator, causing it to malfunction and reducing the performance of your tool.
To clean the commutator, start by removing the carbon brushes. This will expose the commutator and make it easier to clean. Before proceeding, make sure that the power is disconnected and the tool is unplugged.
Once you’ve removed the carbon brushes, apply contact cleaner (for electronics) onto the commutator. Use a cloth to gently wipe away any dirt or debris that has accumulated on the surface. You may need to repeat this process a few times until the commutator is completely clean.
Next, grab P600 sandpaper and gently rub it in a circular motion on the commutator. This will help remove any stubborn dirt or debris that was not removed by the contact cleaner. Be careful not to apply too much pressure as this could damage the commutator.
After sanding, spray some more contact cleaner onto the commutator and wipe it off with a clean cloth. Make sure there is no residue left on the surface.
Finally, reinsert the carbon brushes and put your angle grinder back together. You’re now ready to use your tool again with improved performance.
Regularly cleaning your angle grinder’s commutator will help keep it running smoothly and extend its lifespan. Remember to follow all safety guidelines when working with power tools and always disconnect the power before cleaning or performing maintenance on your angle grinder.
Lubricating The Angle Grinder
Lubricating your angle grinder is an essential part of maintaining its performance and prolonging its lifespan. Before you start using the tool, make sure to check the grease level. If it’s low, add some high-quality grease to the gearbox. This will help reduce friction and prevent the tool from overheating.
To lubricate the angle grinder, you’ll need to remove the gearbox cover. Use a screwdriver to unscrew the bolts and gently lift off the cover. Once you have access to the gearbox, wipe off any old grease with a clean cloth.
Apply a small amount of grease to the gears and bearings, making sure to spread it evenly. Don’t overdo it as too much grease can attract dust and debris, which can clog up the gearbox and reduce its efficiency.
Once you’ve applied the grease, put the gearbox cover back on and tighten the bolts. Make sure it’s properly secured before you start using the tool.
It’s important to lubricate your angle grinder regularly, especially if you use it frequently or in harsh conditions. A well-lubricated tool will run smoother, cooler, and last longer than one that’s not properly maintained.
Storing The Angle Grinder Properly
Once you have finished cleaning your angle grinder, it’s important to store it properly to prevent any damage or accidents. First, make sure to unplug the tool and remove any attachments such as grinding discs or blades.
Next, find a safe and dry place to store the angle grinder where it won’t be knocked over or damaged. It’s best to keep it in a locked cabinet or on a high shelf out of reach of children.
If you have a corded angle grinder, wrap the cord neatly around the tool and secure it with a twist tie or Velcro strap. For cordless angle grinders, make sure to remove the battery before storing it.
It’s also important to keep the tool clean and free from dust and debris while in storage. Cover it with a cloth or dust cover to protect it from moisture and other environmental factors.
Regularly inspect your stored angle grinder for any signs of damage or wear and tear. If you notice any issues, address them immediately before using the tool again.
By taking these simple steps to properly store your angle grinder, you can ensure its longevity and safety for future use.
