OPERATION

CAUTION:
Make sure that the correct size of
the cutting dies are installed to the tool. Check
the cutting capacity written on the cutting dies
before cutting.
CAUTION:
Before pulling the switch trigger,
be sure to set the threaded rod so that its thread
fits with those of cutting dies. Incorrect alignment
of the threads may break the cutting die and cause
personal injury by flown off fractions.
CAUTION:
Replace the cutting dies if the
cutting edge is chipped or deformed.
When cutting, place the threaded rod perpendicular to
the cutting line as shown in the figure.
► Fig.18: 1. Cutting line
NOTE: When cutting a threaded rod made of ductile
metal such as stainless steel, burrs may be generated
on the cut end. Remove burrs with a file in this case.

Cutting secured threaded rods
When cutting a threaded rod which is secured to the
building structure such as the ceiling, wall, floor, etc.,
follow the procedure below :
► Fig.20: 1. Threaded rod 2. Cutting die on the sta-
tionary mount
1. Bring the tool so that the threaded rod is posi-
tioned between the cutting dies.
2. While the threaded rod contacting with the rod
guide, fit the thread of the rod with that of the cutting die
on the stationary mount.
3.
Pull and hold the switch trigger until the cutting
is finished and the jaw of the cutting die comes to fully
opened position.
NOTICE:
Clean the front face of the tool and the
tip of the guide scale before operation. They may
dirty the contacting surface.
Cutting loose threaded rods
When cutting a loose threaded rod on the floor or a
work table, follow the procedure below :
► Fig.21: 1. Threaded rod 2. Cutting die on the sta-
tionary mount
1. Position a threaded rod between the cutting dies.
2. While the threaded rod contacting with the rod
guide, fit the thread of the rod with that of the cutting die
on the stationary mount.
3. Pull and hold the switch trigger until the cutting
is finished and the jaw of the cutting die comes to fully
opened position.
When cutting a long threaded rod which is hard to hold
by hand, place the tool as illustrated. The tool can be
placed flat. The cover also can be used for supporting
the end of the threaded rod.
► Fig.22: 1. Cover (Position 1) 2. Rod guide (Position 1)
3. Cover (Position 2) 4. Rod guide (Position 2)
The cover has markings to indicate its position.
Depending on the size of the threaded rod, put the
cover in the position as shown in the table as well as the
rod guide.

Quitting the cutting in the middle
CAUTION:
Never try to pull out the tool forci-
bly from the threaded rod. It may cause unexpected
start up which cause personal injury or damage to the
cutting die and tool.
When quitting the cutting in the middle, set the revers-
ing switch lever to the reversing position and pull the
switch trigger until the threaded rod is completely
released from the cutting dies.
