4.5. Controls and adjustments
The machine has the following controls and adjustments as shown in Figure 4.2-1:

Handle for adjustment of the upper blade

Push button for cutting
4.6. Operation
The natural stone blocks can be placed on the roller bed with the same orientation as on the
pallet.
By turning the handle on the top of the machine, the distance between the upper and lower
blades can be adjusted. The blades always remain parallel because the spindles on both sides of
the blades are connected by a chain drive.
The upper blade must be adjusted so there is 0 to 5 mm of free space above the stone.
As soon as the machine is connected to the mains supply, the hydraulic unit is in "stand-by".
During the cutting movement, the lower blade moves upward. The stroke is 25 mm.
The lower blade moves upward when the appropriate push button is pushed, see Figure 4.2-1.
When the push button is released again, the lower blade returns to its original position.
The upper and lower blades are made of hardened steel and each have 3 cutting edges. When a
cutting edge has become dull, the blade can be rotated. To see how the blades are attached,
see the exploded view drawing.
