SETTING THE PIPE
1 . Open both chucks wider than the size of the
pipe to be cut and insert the pipe from the rear
chuck side where possible.
2. Close the rear chuck and, holding the pipe
in your right hand, close the hammer chuck
to grip the pipe. Jerk the hand-wheel sharply
towards you to lock.
3. A sharp jerk in the opposite direction will
release the pipe after cutting has been com-
pleted.

HINTS FOR SHORT-PIPES
Setting a short pipe (which does not reach the
rear chuck). With the hammer chuck slightly
loose, move the pipe into contact with the dies
as shown in the diagram.
This will help hold the
pipe on center while
the hammer chuck is
tightened. In this way
a smooth taper cut is
ensured every time.
LONG-PIPE
In case of long size pipes. In case of threading
long size pipes, use the pipe support to pre-
vent vibration during rotating due to warping
or instability of the machine due to material
weight.
If the pipe support is not provided, threading
can not be made correctly, or the machine is
troubled, causing accidents and injuries.

POWER SUPPLY
Before using, check the voltage on the name-
plate. Use only an AC power supply and always
ground the machine before use. In an exten-
sion cord is used, it must be as short as pos-
sible and of sufficient capacity of the power
supplied.
CAUTION: Before connecting the plug
socket, check that the machine switch is turned
OFF, to prevent abrupt moving, causing injuries
and accidents.
PIPE CUTTING
1. Raise the die head and reamer out of the
way and set the pipe at the length to be cut.
2. Open the pipe cut-
ter wider than the
diameter of the pipe
and lower it into posi-
tion.
3. Tighten by turning the handle to the right
until the cutter wheel firmly engages the pipe,
start the machine, and tum the handle 1/4 of a
revolution for each revolution of the pipe be-
ing cut until the pipe is completely cut.
WARNING: If the cutter handle is tumed too
violently, when the cutter wheel cuts into pipe,
it can distort the shape of the pipe.
SPECIAL CUT GRINDER PRECAUTIONS
We strongly recommend
that only the pipe cutter
attached to the machine
be used to cut pipes that
are to be threaded.
If a grinder is used, malee
sure that the cut face is
square and without steps as in the next illustra-
tion.
REAMING
1. When cutting is complete, raise the cutter
out of the way. Lower reamer arm and push
the reamer handle toward the pipe (1).
2. Long-chucked pipe can sometimes be
reamed with the reamer handle in the recessed
position.
3. Lock the reamer in position by turning the
reamer handle anti-clockwise (2).
