rise to the start position. Adjustments can be
made.
- Use the cycle start switch to continue the cutting
cycle.
- For unsafe and emergency conditions use the
emergency stop button 6.1 M. Using emergency
stop button 6.1 M will stop the machine in last
position. The motor and hydraulic will stop and
control setting will be reset.

restarted.
6.3 Automatic shutoff during machine
operation
If there are any improper operation or situation,
the machine is designed to automatically shut off
during the operation cycle to prevent any further
damage from occurring.
- If the hydraulic pump is on and the machine has
not been active for 5 minutes, the power will be
shut off.
- If the time take to clamp the vise is over 40 sec,
the power will shut off. The vise pressure warning
light will flash in warning.
- After cutting the saw bow has taken more than
40 sec to rise to the start position, the power will
shut off. The upper stroke-limit indicator light will
flash in warning.
- After pressing the start button, the vise clamps
the work piece, and saw bow begins cutting. If the
cutting time is unable to finish within 90 minutes,
the lower stroke limit indicator will flash in warning
and the power will be shut off.
If any of the above situations occurs, reset the
machine by pressing 6.1D. This will change the
operation mode – manual or automatic.
