Do not remove the riving
knife for saw operations.
For slotting or grooving, the riving knife has to
be adjusted in such a way that the upper part of
the riving knife is never set lower than the
highest sawtooth in use.
Starting the Machine
NOTE: The machine will not start if the blade
cover or the rear door is open.
When starting in Star-Delta mode, proceed as
follows (Figure 19):
1 – Turn Main Switch to position "I".
2 – Turn Star-Delta switch into star position "Y".
3 – Push Main Motor start button.
2 – After five seconds, put Star-Delta switch into
delta position "∆".
This five second delay is
necessary for the motor to gain full speed
before switching to delta. If you forget to
switch to delta, the motor will operate at full
speed but without power, and the motor may
become damaged.
4 – Push Scoring Motor start button (main motor
must be running).
5 – Emergency stop button halts both main and
scoring motors.
The main motor is equipped with an automatic
brake which stops the motor within 10 seconds
after the machine is shut off.
Fuses are located inside the electrical control
panel. The machine must be disconnected from
power supply when opening this panel.
This machine has overload protection on both
main and scoring motors. Should the motor be
shut off by one of these protectors, wait a few
minutes until the overload has cooled down
before restarting.
Dust Collection
It is strongly recommended that a dust collection
system be connected to the HPS67. The dust
collector should have sufficient capacity for this
size machine. Both the outlet on the blade guard
and on the machine base should be connected
to the dust collection system.
