The concept of a concrete grinder is very simplet doesnt matter if youre using a small handheld grinder or a bigger single head machine - they work the same wayhe head rotates, grinding the surface of the concrete beneath, and different attachments can be used to get you the results you want. HANDLE POSITIONS AND PLUGS Most machines have adjustable handles and controlshere are three different handle positions Operating positionhis is the position you use the machine inost of our concrete grinders are adjustable to suit different heights. Tooling positionhis position makes it easier to tilt the machine up so you can change the discs and pads. Lifting and storagef youre lifting the grinder on and off trucks, putting the handle into the lifting position makes it easier to move around and store. The concept of concrete grinding is basically the same as for woodwork or metalworkou start off with the most abrasive plugs then move down to softer discsf youre polishing, youll want to finish off with resin pads. DUST CONTROL As well as checking you have all the plugs and discs you need, youll also need to make sure you have some dust control measures in placeost concrete grinders come with a vacuum attachment to remove dust as you gonother option is to dampen the surface youre working on with water from the hose, but be aware this will create a slurry so can be a very messy processou cant vacuum if youve used water, so its one or the other. Machine Operation and TipsTO OPERATE THE MACHINE Check you have the right plug attachment more about changing plugs and discs below Put the handle setting into operating mode and adjust it to your heightou want to be comfortable using the machine and you may also need to push it down and take a bit of weight off the head as you go, depending on the surfaceur machines come with adjustable weights that you can add and move around if you need a bit more or less pressure on the grinding head. Check your vacuum hose is in place, if youre using it. Tilt the machine back slightly before you turn it on to free up the grinders from the surface. Press the green start button. If the machine trips out, the overload button will pop outet the machine cool down for a couple of minutes, then push the button back in and keep going. CHANGING THE DISCS AND PADS Many of our machines come with a number of different attachmentsach disc or pad is suited to a different stage in the concrete preparation processhe plugs are for the heavy grinding work, discs for finer work and then the pad is used for polishing. As you progress with your concrete surface preparation, you will need to switch plugs and discswitching plugs is very easy we always recommend you wear gloveset a hammer and tap it on the plate near the plug and the plug should pop outo put plugs in, just push them with a bit of force and they will bind in. When its time to change from plugs to a disc, take the plug out and put in the magnetic plug that comes with the discsext, put the insert through the disc and then attach the disc to the magnetic plug. Tip When changing discs back to plugs, make sure you take magnetic plugs out.
