How to use our 480 Satellite Concrete Grinder

Safety

On delivery of your grinder hire, the operator must carefully read the safety instruction manual that is delivered with your grinder. The operator should be physically able to handle the bulk weight and power of this machine, however, don’t be afraid, it doesn’t take that much strength. It is important to ensure the machine is never left unattended while in operation. Ensure suitable clothing is worn including steel cap safety boots, hearing protection, safety goggles and a suitable dust mask. Concrete dust is known to have up to 50% silica content and can be harmful if inhaled. Machine can only be used on relatively flat surfaces and not steep grades. If the machine becomes difficult to hold on to, the floor surface is too steep.

How to get started

Firstly, cart the grinder to its dedicated work area, ensure the area is free of objects, loose material, dirt etc. Shift the handle of the machine into tooling position, the machine will now be standing vertically up right with the handlebars in the air. Now using your preferred foot, place pressure on to the rear base plate of the machine and tilt it on to its back into the tooling position. You are now ready to install your preferred diamond tooling.

Installing the diamond tooling

To learn more about what diamonds to use, refer to our Diamond Tooling guide HERE. There are 2 different types of blades that you can use with your 480 satellite grinder. The first option is diamond plugs. With this option, 3 plugs must be used to operate the machine, these are inserted equally into the tooling disk ports located underneath the machine under the base of the shroud. These are to be very lightly tapped into place using a hammer, though carefully not to damage the diamonds. The other option is to use diamond cup wheels, these are installed by equally tapping in 3 magnetic plugs into the ports. These plugs have a removable pin that can be removed, the diamond cup wheels are then pinned in place, sandwiched between the pin and the magnetic plug. This allows for easy change over of diamond cup wheels. The machine can then be tilted back up vertically, and the handle reverted to the OPERATING position. It is now time to level the machine.

Levelling the machine

Located behind the motor, there is a level bubble provided. By pulling the axle lever, the frame of the machine can be adjusted which subsequently changes the user experience. For optimal comfort, adjust the axle lever to set the bubble slight forward. This will also assure longevity of the diamond tooling life.
Connecting the dust extractor and powering up

Connect your dust extractor into the machine via the supplied extraction hose. Using an extension lead, connect the grinder into single phase 240v power using a standard 10-amp plug. In simple terms, your standard house power is sufficient. It is important to always use the heavy-duty extension lead that is supplied with your rental, this can handle high amperage and will ensure the machine is operating at its full potential. Turn the power on and you’re good to go. It’s time to start grinding!
Operating the machine

Before you power up, turn on the vacuum and clear the area. The on/off switch located on the handlebars is used to power the machine on. Ensure you have a firm hold of the handlebars before powering on. While operating, its important keep the grinder moving and not holding it one spot, this will ensure you don’t leave any harsh swirl marks in the concrete. Depending on the type of grinding you’re doing whether its surface preparation, glue removal or polishing, you will need to move the machine at different speeds. A good starting point is to move 1 meter every 10-15 seconds. From here you can slow down or speed up and this will give you a good idea of the speed you need to move at to achieve your desired finish.
