ROUBLESHOOTING
7.4.1 Insufficient cooling water flow
If the cooling pump does not deliver water to the diamond disc, carry out the following
operations:
•
Pull the plug from the power socket.
•
Check that the adjustment tap on the cutting head is open.
•
Check that the water in the tank completely covers the pump.
•
Check that the tube leading from the pump to the disc guard is not obstructed.
•
Check that there are no fragments obstructing the pump filter.
•
Check that the fan is not jammed and clean off any dirt residues.
•
If the fan is jammed, start it by hand when turning on the machine.
7.4.2 Difficult carriage sliding
The head carriage has two eccentric screws positioned
on the right-hand side of its upper face as shown in
the figure. If after lubricating the pulleys and the
guide, there should be excessive carriage sliding
friction or oscillation during its movement, adjust the
eccentric screws to reach the right friction coefficient.
Turning these screws, you can slightly decrease or
increase the distance between the two movable
pulleys (on the right-hand side) and the two fixed
ones (on the left-hand side) with the result that you
can vary the force with which the pulley races tighten
on the sides of the fixed guide and ultimately the
carriage sliding friction.
N.B. The eccentric stroke is obtained with only one
turn of the screws. Therefore, making more turns is
pointless. Turn the cams by making several “to and
fro” movements along the transverse line of the carriage to find the right adjustment. If
you cannot find the right adjustment even if turning the cam to the maximum, replace
the pulleys.
