Do not allow the tool bit to burnish the surface. If chatter problems occur, decrease
the feed rate and the speed. Then, make sure that the tool bits are sharp and that
you use the tool bits of correct type for the material. Stainless steel can harden
during work. Thus, cut stainless steel with a high enough feed, 0.08
–0.15 mm
(0.003
–0.006″) per rotation, to cut under the hardened surface.
If an overload occurs and the rotation stops, promptly turn off the
motor. The motor turned off too late can cause damage to the machine.
To start the work again, rotate the feed knob to the left to retract the tool bits from
the pipe. Then, start the motor and cut the material with a lower feed rate. Do not let
the motor overload. If possible, cut hard materials with a low feed rate and speed.
After the pipe end is machined fully, stop rotating the feed knob and allow several
more turns of the spindle to improve the finish of the surface. Then, use the ON/OFF
lever/switch to turn off the motor, and wait until the rotation stops. Next, rotate the
feed knob to the left to move the tool bits away from the pipe end to at least 3 mm
(0.12
″). Then, rotate the clamping knob to the left to release the clamping, and
remove the machine from the pipe.
Use petroleum ether to clean the pipe from excess coolant. Clean the machine
with a cotton cloth and no chemical agents.
