• The repair ofreinforcements (suchasside
members) byheating isnot recommended
since itinvolves theriskoflowering strength.
When heating isunavoidable, donot heat
such parts attemperatures above550°C (1,

022°F)

Heating temperature shouldbeverified with
a thermometer. (Acrayon-type andother
thermometer areavailable.)
• When straightening bodypanels, usecaution
in pulling anyHSS panel. Because itis very
strong, thismay cause deformation inadja-
cent portions ofthe body. Inthis case,
increase thenumber ofmeasuring points,
and carefully pulltheHSS panel.
Special
consideration forHSS must begiven tothe following points:
1 .Additional pointstoconsider
• Incutting HSSpanel, avoidgascutting if
possible. Instead,useanairsaw orahand
cutter toavoid decreasing thestrength of
surrounding portionsduetothe influence of

minimum allowance of50 mm (1.97 in)
must begiven.
