4 . Start the machine and tum the caniage han-
dle to the right to advance the reamer (3).
5 . When reaming is complete tum off the ma-
chine, retract the reamer handle and raise the
reamer arm into the rest position.
THREADING INSTRUCTIONS
Setting the thread size
Loosen the lever nut and set the index line to
the desired thread size and tighten firmly.
1. Fit the appropriate die head as shown in the
next illustration.
2. Push the cam-plate handle forward to set
the auto-open lever, then set the thread size
by fitting the lever nut to the appropriate posi-
tion.
3. Switch on the machine and the thread cut-
ting oil will automatically flow out from the
die head.
4. Turn the carriage handle clockwise until the
dies have engaged the pipe for 3 or 4 threads.
From this point the carriage handle may be
released. A standard taper thread will then be
cut automatically.
5. Once threading has been completed, switch
OFF, and turn the carriage handle to the left.
Retract the die head from the pipe.
PRECAUTIONS FOR THREADING
1 . As the dies come into contact with the pipe,
the lever should be turned gradually increas-
ing strength until the dies are biting firmly.
After the dies fully engage the pipe will travel
smoothly by itself, but optimum cutting will be
assured if the Iever is turned with slight pres-
sure to keep pace with die movement.
CAUTION: If the machine suddenly stops
during threading, tum off immediately (a de-
lay will result in the motor buming up).
2. To stop threading, turn the auto-open lever
to the left.
ADJUSTMENT OF THE THREADING LENGTH
A device for adjustment of the threading
Iength is attached. Use this for making threads
of the desired length as follows.
Adjustable capacity:
1-2" (3 threads)
1/2-3/4" (4 threads)
ADJUSTMENT
1. Loosen the socket
head cap screw on the
auto-open lever (C).
2. Move the auto-
open lever to the right
for longer threads or
to the Ieft for shorter
threads as indicated
by the arrows in the
diagram.
3. Retighten the socket head cap screw.
MAINTENANCE
Our products are made with the finest materi-
als throughout, but even the best needs atten-
tion sometimes. To ensure a long and trouble-
free working life for your machine, we recom-
mend the following maintenance procedures.
1. Main shaft lubrication.
The main shaft bearings
are made with specially
designed oiled metal, but
should be lubricated once
every six months with
spindle oil or machine oil to ensure smooth
running.
