Precautions
You are required to read this manual in detail to familiar yourself with functions
of machine. Earthing and fuse are required in the circuit. Never run the
machine overload.
IV.Driving System
In this machine, the tapping saw is directly
driven by a reduction motor, resulting in a
reduced loss of mechanic power. The
feeding movement is realized by manual
rack and pinion system.
V.Electric SystemThe Electric System of this Machine consists of an electric motor, a switch and
cables. The stop/start of the machine is controlled by the switch. An electric
motor is the only load. The power supply shall agree with the requirements of
motor: three phase, 380 V, 50 Hz. Sound earthing of ground wire (black) is
required prior to starting the machine.
VI.Operation and Adjustment
Put the machine on the steel tubing to be tapped and let the V-shaped surface
at the bottom touch the tubing (Refer to Fig. 1). Let the machine run idle to
check whether it’s normal (Observe the rotating direction).Turn the feed lever
slowly. First tap a location hole with center bit. Then tap the hole to its size.
Add coolant to the saw during operation to extend its service life significantly.
VII.Maintenance
Be gentle in operation. After operation, apply anti-rusty oil to the surface of
slide after cleaning it. Add lubrication grease to all the joints of moving units.
Never operate the machine overload.
