4.8 Performing the cutting work
• Align the joint cutter to the cutting line.
• Open the water shut-o valve and regulate the required
water quantity.
• Lower the diamond saw blade slowly to the desired cut-
ting depth. Hold the joint cutter rmly!
• Proceed in several steps when deep cutting operatings
are to be performed.
Cutting depth per cut:
– Asphalte up to 10 cm
– Concrete up to 6 cm
• After lowering the saw blade to the desired cutting
depth tighten the cutting depth adjustment.
• The motor should continue to run at approximately
nominal speed.
• The cutting feed is generated by pushing the joint cutter
forward. Start moving the joint cutter slowly and keep
pushing forwards evenly! Choose the feed rate in such a
way so that the motor rpm is slightly reduced!
4.9 Finishing cutting operations
• Move the joint cutter a little backwards 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. Keep the machine in its position. Now se-
cure the hand crank against unintentional displacement.
• Activate the xing brake as described in section 4.3.
• Stop the water supply.
• Switch o the blade drive motor by putting the star delta
switch in to position “0”!
The joint cutter is additionally equipped with an emer-
gency 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 control box of
the star-delta reversing switch.
4.10 Replacing the diamond saw blade
The diamond saw blade is replaced:
– after complete wear of the diamond segments
– when the material to be cut changes.
Replacing the diamond saw blade is absolutely
necessary:
– if it is worn down unevenly
– if the diamond segments are damaged or broken o.
For mounting a new diamond saw blade please proceed as
described in section 4.2.
