Cutting operation
• Align the machine with the cutting line.
• Open the water shut-off valve and set the amount of
water required.
• Move the diamond saw blade to the 0 position.
• Slowly lower the saw blade to the desired cutting depth
by actuating the cutting depth adjustment spindle.
Hold the joint cutter firmly during this process.
• Make deep cuts in several passes!
Cutting depth per cut:
– Asphalt up to a depth of 10 cm
– Concrete up to a depth of 6 cm
• After lowering the diamond saw blade to the desired
depth, the cutting depth adjustment is locked.
• The motor should remain approximately at its rated
speed.
• Feed is generated by pushing the machine. Slowly start
the machine and continue pushing it at a steady speed.
Select the cutting feed so that the speed of the motor is
slightly reduced.
4.10 Finishing cutting operations
• Move the joint cutter backwards slightly in order to allow
the diamond saw blade to turn freely in the cut.
• Release the hand crank and raise the diamond saw blade
out of the cut while the machine is running. Keep the
machine in position. Now secure the spindle against
unintentional displacement.
• Apply the parking brake as described in section 4.3.
• Shut off the water supply!
• Switch off the blade drive motor using the star-delta
reversing switch.
ATTENTION
The joint cutter is additionally equipped with an
emergency stop button which enables its quick
separating of the motor from the power supply in case
of danger. The emergency stop button is located on the
control box of the star-delta reversing switch.
