INTRODUCTION
MERAX Pipe Threaders can cut, thread and ream ½” – 6” pipes, according
to the model). Compact, easy to handle and highly efficient, they feature a safe
automatic mechanism and an innovative lubrication system.
Purchasing this Pipe Threader, you will notice it extends the life of dies,
protects pipes from deforming and have a high quality output. It is the ideal
machine for achieving higher efficiency, guaranteeing quality for your projects and
sharply reducing work in pipe installations, being widely used in industrial
installations.

STRUCTURE
Made of highly resistant cast alluminum alloy and polished steel alloy, it is a
lightweight, but heavyduty machine. FIG 1 shows the machine structure, die head,
reamer and pipe cutter, which move along the support brackets. The motor,
reducer and oil pump are assembled within the machine.
FIG 1
PREPARATION
1 –Care during transportation:
Lock the die head in the threading position with dies completely open. Lock a
small piece of pipe in the front chuck and fasten the pipe cutter to it. Lock the
reamer in the operation position.
Empty the Oil Threader reservoir, releasing the cap at the bottom of the
reservoir.
The machine can be safely transported now.
2 –Preparing for operation:
To operate the machine, the legs should be adjusted so that the back chuck is
at a higher position than the front chuck.

OPERATION GUIDE
A –Adjusting the pipe:
(1) Open both chucks and place pipe beginning from back chuck.
(2) Close the back chuck, pressing the clamps against the pipe. Close front chuck:
with the hands on the wheel, pull it towards your body to lock pipe.
(3) A sudden movement in the opposite direction will release the pipe after cutting.
(4) Using short pipes that do not reach the back chuck, with the front chuck lightely
loose, place the short pipe and tighten it, using the front edge of the dies. This
procedure should help to keep pipe centered while front chuck is fastened (
FIG 2 ) .

B –Preparing for threading:
(1) Select the adequate dies for the job.
(2) Place the set of dies in the die head as numbered.
(3) Release the lever and pull it until dies are locked.
(4) Place thread length selector in the required position (except ZIT-R2A).
(5) Select the desired thread diameter on the reference line. (FIG 3).
(6) Select the speed lever for the recommended size (available in some models).

C –Threading:
(1) Move the pipe cutter and the reamer out of the way, lower the head until it
touches the edge. Use hands to press until it is locked. When the thread head
is securely locked, press the switch to begin.
(2) With the pipe turning, turn the cart wheel couterclockwise to move threading
head against the pipe. Make sure oil is flowing through the threading head
before beginning to thread (check the oil flow adjustment button, available in
some models) FIG 4.
(3) Pressure the carriage wheel counterclockwise until dies lock the pipe at a
distance of 3 or 4 thread lines. Repeat the procedure of pipes of 2 ½” or more.
(4) At this point, the carriage wheel can be released. A standard thread will
automatically be made. At the end of the thread, the dies will open up and the
threading operation will be complete (except Z1T-R2A).
(5) Stop the machine, remove the carriage until die head releases the pipe. Pull
the thread head lock button (except Z1T-R2A) and lift it to the rest position.

D - Setting the thread diameter:
The size scale position is factory preset. If recalibration is necessary, proceed
as follows:
(1) Make 2 or 3 threades to determine the desired size. Lock the lever nut in this
position.
(2) Release the bolts to change the scale as desired. Re-tighten screws. (FIG 3)
