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 System

The 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.
