Power Supply
Before using the machine check the voltage on the
nameplate.
Use only an AC power supply and always earth the
machine before use. If an extension cable is used, it
must be as short as possible and of sufficient capacity
for the power supplied.

ENGLISH
Caution! Before connecting the plug to the power
supply, ensure that the machine is turned to OFF to
prevent abrupt movements that could result in injury
or accidents.
Positioning the Pipe
1. With the machine stopped open the two chucks
enough to allow the pipe to be threaded to go
through and, if possible,always insert it through
the rear chuck.
2. Close the rear chuck and close the hammer chuck to
hold the pipe. Jerk the hand wheel sharply towards
you to lock it.
3. A sharp push in the opposite direction will loosen
Hammer chuck
the pipe after the operation has been carried out.
When threading long pipes, use a pipe support both to
ensure that the pipe does not vibrate due to warping
as it rotates, and to ensure that the machine does not
become unstable due to the weight of the pipe.
If you do not use a pipe support, it may prove difficult
to produce proper threads, or the machine may be
damaged and result in accidents or injury.
Pipe Cutting
With the machine stopped:
1. Raise the die head and reamer out of the way and
set the pipe to the length to be cut according to
the instructions in "Positioning the pipe".
2. Open the pipe cutter wider than the diameter of the
pipe and lower it into its cutting position. It can be
adjusted by moving the carriage.
