Warning!
The wheel and the machine are hot. Cool them down before removing.
Prohibition!
Do not touch the rotating parts.
Warning!
◎
Use safety goggles when cutting a pipe to protect your eyes from chips.
◎
Grooving work can have larger kickback than cutting work, which can cause not only damaging
the wheel but also serious injury. Therefore, make sure to start grooving gently.
Caution!
Never shut down the engine when the wheel is in contact with the groove. This can damage the
wheel and cause the trouble.
Caution!
Leaving rusty matter can cause trouble such as wobbling cut and slipping.
Step 4: Start Grooving
Start grooving gently by lowering the Grooving Wheel slowly in the same manner as the Cutting
Wheel to avoid kickback.
Step 5: Grooving depth adjustment
A) When the wheel starts grooving, keep lowering the wheel until the Grooving Depth Adjusting
Wheel hits the pipe surface. This means that the Grooving Wheel reaches the prescribed depth.
Take notice that when the Grooving Depth Adjusting Wheel on the pipe surface, it stops rotating.
B) Tighten the wing nut to hold and keep it from moving. Turn the clutch handle down to start
grooving all around the pipe.
Step 6: Finish Grooving
A)
Keep the machine run until grooving noise and chips are not recognized.
B) When the groove is completed, turn the Crank Handle slowly clock wise (upward) to raise the
grooving wheel. Shut down the engine after the wheel is completely raised.
C) Shut down the engine. Make sure the wheel is completely stopped. Remove the machine from the
pipe.
D) Clean and oil the machine after usage. (Refer to
Section 4 Maintenance)
