Operating Manual
18
The start of the grinder and the filter unit is affected in the following sequence:
1. Switch on the filter unit.
Initial operation of the grinding machine:
1. Assure the fuel supply is on and is connected correctly to the fuel tank.
2. Assure the dust hose is connected correctly to filter and machine.
3. Check that throttle is in idle position.
4. Ensure the Rocker Switch is on the “off” position.
5. Turn the ignition key.
6. Place downward pressure on handle. Once the digital display reads 2,000 RPM, push the
Rocker Switch.
7. Release pressure from handle and immediately begin moving the machine from side to side
to prevent the tools from digging into the concrete surface and creating an uneven profile. For
the operation of the running machine, it is necessary to move the machine from side-to-side
to create an even profile that is consistent in flatness and profile.
8. Throttle up to the desired speed — minimum recommended operating speed of 2,800 RPM
and no more than 3,500 RPM.
9. When grinding in work area is complete, throttle down to 2,000 RPM and push the Rocker
Switch.
10. Turn off fuel supply at tank.
11. After motor stops from fuel supply being cut off, turn off ignition key to save battery power.
Do not overfill the bin to avoid dust exposure when opening the bin. Comply with the
local waste treatment regulations considering the removed material.

6.1
Daily Operation
Normal start-up and operation of the grinder is not different as has been described in Chapter 5—
Initial operation.
Carry out grinding operation in parallel tracks in a way that the dust hose and electric cable do not
become twisted. Make sure that no vehicles, such as forklift trucks and other equipment, run over
the electric cable and the dust hose.
The speed of moving the grinding machine over the work surface will influence the final finish and
production.
