PART 4 INSTALLATION AND OPERATION
SECTION 1
TOOL FEED / BACK INSTRUCTION
A. BT1/BT3/BT6 tool feed / back hand wheel
See figure:
Tool F ee d : rotate c l o c k w i s e
Tool B ac k : rotate counterclockwise
B. BT8/VBT14 adopt tool feed/back ratchet spanner
See below figure:
Tool F ee d : P r e s s paw l clo ck w i s e , pull s p a n n er c lockwise
Tool B ac k : P re ss paw l counterclockwise, pull spanner counterclockwise
OPERATION PROCEDURE
1. Measure the ID of the pipe, and then choose the proper expanding block according to the diagram
of expanding blocks, (see the figure on the expanding blocks), choose proper block, fix them on
the wedge block, and tighten.
2. Install the proper tool bit on the cutter. Make sure the tool bit is clockwise.
Caution: The tool bit can not touch the spindles; otherwise may damage the machine
3. Back the travel of tool bit by tool feed using hand wheel (tool feed/back ratchet spanner). Insert
the expandable mandrel into the pipe, fasten the expansion nut lightly, shake the machine (in
order to center, and make the expanding block properly contact the ID pipe), the machine will be
centered, Then fasten the expansion nut tightly, make sure the equipment and the pipe are fixed
solid.
Caution: The expandable mandrel should not be inserted too deep, it’s better to keep a 2-3mm

8
distance between tool bit and pipe end high point.
4. Turn on the motor then turn off, let the cutter rotate 1 circle, in order to confirm the machine and
tool bit are installed correctly before cutting, Turn on the motor, rotate the tool feed hand wheel
(tool feed/back ratchet spanner) manually until the tooling makes contact with the pipe.
Caution:
4.1 Manually feed the tool bit with an even motion.
4.2 Continue to spray coolant (saponification oil) while working This will make the beveling
smooth and prolong the tool bit life
4.3 If the tool bit becomes dull, sharpen it or replace with a new one
4.4 While working, avoid scrap-iron from going into the motor.
5. After beveling is completed, back the travel of tool bit by tool feed hand wheel (tool feed/back
ratchet spanner) first, then turn off the motor, loosen the expansion nut, and take off the machine.
Caution: If you do not back the travel of tool first, the feed wheel may be damaged, resulting in
the expansion nut and feed wheel getting stuck.. Please repeat the above, if the machine is for
continuous working, in order to make sure the machine operates normally.
6. After the tool bit is installed , the machine can be moved and continue processing from one pipe
to another same size pipe, no need to adjust the tool bit again, only back the travel of tool bit.
Loosen the expansion nut, and fix it on another pipe.
Caution: When loosening the expansion nut, and taking the machine out or adjusting the location
of machine, do not let it slip into the pipe.This may damage the tool blade
NOTES FOR PNEUMATIC SERIES
1. Compressed air required: Dehydrated and filtered air
Required air treatment: air filter, regulator and atomized lubricator (FRL system)
An air filter makes the compressed air dry and clean, avoiding rust and damaging the air motor.
Atomized lubricator lubricates the air motor internals
If you do not have a FRL system, add lubricating oil (engine oil and kerosene 1:1) at air in-inlet
every time before and after use, and clean the motor parts regularly
Caution: This is a remedy and not recommended use, Recommend the air filter and atomized
lubricator to maintain air motor
2. While working, if the tool feed speed is too fast or low air pressure makes the cutter stop rotating,
turn off the air valve and back the tool immediately. Fix air supply issues before continuing work.

PART 5 IMPORTANT NOTES
1. The carbon brush was adjusted before dispatch, they can feed automatically. Please do not adjust;
Note: After 100 working hours, check the wear condition. Replace the carbon brush if needed. If
the carbon brush wears out, please turn off the machine immediately, otherwise the motor will be
damaged. We suggest: when carbon brush wears 2/3, replace the carbon brushto aviod motor
damage.
2. If the tool bit is dull, bevel resistance will increase and spline shaft and/or motor and reducer
parts will be damaged. Please sharpen tool bit or replace with a new one.
If you sharpen the tool bit, one tool bit can be used multiple times
If the tool bit is dull and tool feed is too much it may cause the motor to stop. Turn off the power
immediately, otherwise the motor and machine may be damaged.
How to check if the tool bit is dull or sharp:
Figure 1: tool bit is sharp, scrap-iron is a strip
Figure 2: tool bit is dull, scrap-iron is fragment
3. Continue to spray coolant (saponification oil) while working to make the beveling smooth and
prolong the tool bit life
4. Before beveling, please remove the rough edge and other incidentals after flame cutting with
hammer. If the pipe end surface is full of bumps and holes, start at the high point, and feed the
tool bit carefully.
5. When working with small size tube, please use a bench clamp or other tool to fix the tube
6. BT6 and BT14 adopt a tool feed/back ratchet spanner, it is convenient for operator, but must
control the feed speed. If you feed too much it may damage machine.
7. Motor may stop which is caused by a dull tool bitor tool feed is too fast Cut-off the power supply
immediately, otherwise will damage the motor.
8. Operator must read this manual completely before operation, the damage caused by improper
operation will not be covered under warranty.
