(1) Remove the blade, using the procedure on Page 8.
(2) Loosen the "SELI" head fastening bolt and turn the head to
match the slanted cut.
兟
There is a reference line on the side of the "SELI" head.
Using this line as a reference, adjust the position of the
"SELI" head.
兟
When the "SELI" head is moved in the direction of the
white arrow (Fig. 35), the pipe will be cut in the direction
of the white arrow.
兟
When the "SELI" head is moved in the direction of the
black arrow (Fig. 35), the pipe will be cut in the direction
of the black arrow.
Note: In the case of a 100 A pipe, moving the "SELI" head
0.5 mm from the reference line will adjust the slanted cut
approximately 1 mm. However, this is ultimately only a general
guide and will change depending on various conditions, so be
sure to conduct a test cut after adjustment.
(4) Fasten the "SELI" head fastening bolt securely.
(5) Replace the blade, using the procedure described on Page 9.
Note: When the blade has been replaced, move the adjusted
"SELI" head back to the reference position before cutting.
兟
Before inspecting the unit or carrying out maintenance work, be sure to set the ON/OFF switch to the "OFF"
position, and remove the plug from the outlet. If the unit is left plugged in during inspections or maintenance, it
may start up unexpectedly, leading to injury.
兟
If a problem is discovered during inspection or maintenance, check the Troubleshooting table and take the
appropriate action. Continued use of the unit without correcting the problem may result in heat, smoke or fire,
leading to accident or injury.
WARNING
1. Adjusting the "SELI" head angle
(Fig. 35)
Maintenance
In the event of vertical slanted cuts, the problem can be corrected by adjusting the angle of the
"SELI" heads. Be sure to adjust both "SELI" in the same manner.
Before adjusting the "SELI" heads:
Diagonal cutting may be due to one of the causes listed below. Before adjusting the "SELI" heads, check them and
correct if necessary. (It may not be necessary to adjust the "SELI" heads.)
