Floor grinding machine, handle for floor grinding machine and method of setting a handle for a floor grinding machine

A method for setting a position of a handle of a floor grinding machine for grinding floor surfaces, the floor grinding machine comprising:

• a machine frame,
• a grinding head supported by the machine frame,
• a motor supported by the machine frame and operatively connected to the grinding head,
• a handle frame extending from the machine frame and pivotable relative to the machine frame,
• a guide member which is pivotable relative to the machine frame and pivotable relative to the handle frame,
• a first locking device that selectively locks the guide member into physical engagement with the handle frame to prevent pivoting movement of the handle frame relative to the guide member, and
• a second locking device that selectively locks the guide member into physical engagement with the machine frame;
• wherein the guide member is pivotable relative to the machine frame about a first axis, the handle frame is pivotable relative guide member about a second axis, and the first and second axes are coaxial;
• wherein the handle frame is prevented from pivoting relative to the machine frame, in either rotational direction, when the first locking device locks the guide member into physical engagement with the handle frame and the second locking device locks the guide member into physical engagement with the machine frame;
• wherein the method comprises:
• setting a position of the handle frame relative to the guide member, and
• setting a position of the guide member relative to the machine frame.
