3) Precautions in bending
➀
If it is necessary to bend or stretch the tubing,
use the spring which is attached to the tubing in
stead of pipe bender.
• Please make a careful notice to make a smooth
line.
• Hold the tubing with your two hands closely and
then bend or stretch it slowly not to make any
crack.
• Remember that the radius (R) should not exceed
70mm (Refer to Fig. 1)
➁
Do not repeat the bending process to prevent the
tubing from cracking or crushing.
➂
Keep in mind that the bending part should not be
cracked and make the radius (R) as long as possible
(Refer to Fig. 2)`
