8. After setting your vise angle, jaw height and tightening everything down you are ready
to make a notch.
9. The main feed direction for notches is In & Out. The Left to Right is used to position
the tube in the best location on the cutter. All cutting is done on the length (side) of the
cutter and not the end. Keep the tubing as close to the spindle as possible.
WEAR SAFETY GLASSES STAY CLEAR OF ROTATING CUTTER
10. SINGLE SPEED; Be sure the tube is not touching the cutter and then turn the
machine on. Use the switch on the left end of the base plate. Use the IN /OUT crank
wheel to feed the tube into the cutter and create the notch. Using a smooth steady
feed will create the best cut. A little practice and you will “feel” the best feed rate.
VARIABLE SPEED; Be sure the tube is not touching the cutter and then turn the
machine on. You will need to turn the
MASTER switch to ON position and then turn
the
RUN switch to the RUN position. Use the IN /OUT crank wheel to feed the tube
into the cutter and create the notch. Using a smooth steady feed will create the best
cut. Start out with the
SPEED CONTROL in the middle. Begin feeding your tube into
the cutter and change the speed up and down. As you feed the tube and adjust the
speed you will “feel” where the best combination of cutter speed and feed speed are.
Generally the thinner the tubing wall the faster you will cut and the thicker the tube
wall the slower the cutter speed. Use the RUN / STOP switch for normal on / off
between notches. Repeated use of the MASTER switch can cause damage to the
control unit.
When Turning the MASTER SWITCH ON there may be a 3 to 5 second
delay before the machine will power up.
11. Be sure the machine is TURNED OFF AND THE CUTTER HAS STOPPED ROTATING
before removing the tube from the vise.
