 When straightening body panels, use caution in pulling any HSS panel. Because HSS is very strong, pulling may cause
deformation in adjacent portions of the body. In this case,
increase the number of measuring points, and carefully pull
the HSS panel.
 When cutting HSS panels, avoid gas (torch) cutting if possible. Instead, use a saw to avoid weakening surrounding areas due
to heat. If gas (torch) cutting is unavoidable, allow a minimum
margin of 50 mm (1.97in).
 When welding HSS panels, use spot welding whenever possi- ble in order to minimize weakening surrounding areas due to
heat.
If spot welding is impossible, use M.I.G. welding. Do not use
gas (torch) welding because it is inferior in welding strength.
 The spot weld on HSS panels is harder than that of an ordi- nary steel panel.
Therefore, when cutting spot welds on a HSS panel, use a low
speed high torque drill (1,000 to 1,200 rpm) to increase drill bit
durability and facilitate the operation.

2. Precautions in spot welding HSSThis work should be performed under standard working condi-
tions. Always note the following when spot welding HSS:
 The electrode tip diameter must be sized properly according tothe metal thickness.
 The panel surfaces must fit flush to each other, leaving no gaps.
 Follow the specifications for the proper welding pitch.

DESCRIPTION
This section is prepared for technicians who have attained a high level of skill and experience in repairing col-
lision-damaged vehicles and also use modern servic e tools and equipment. Persons unfamiliar with body
repair techniques should not attempt to repair collision-damaged vehicles by using this section.
Technicians are also encouraged to read Body Repair M anual (Fundamentals) in order to ensure that the orig-
inal functions and quality of the vehicle can be mainta ined. The Body Repair Manual (Fundamentals) contains
additional information, including cautions and warning, that are not including in this manual. Technicians
should refer to both manuals to ensure proper repairs.
Please note that these information are prepared for wo rldwide usage, and as such, certain procedures might
not apply in some regions or countries.

 Front pillar butt joint can be determined anywhere within shadedarea as shown in the figure. The best location for the butt joint is at
position A due to the construction of the vehicle. Refer to the front
pillar section.
 Determine cutting position and record distance from the locating indent. Use this distance when cutt ing the service part. Cut outer
front pillar over 60 mm above inner front pillar cut position.
 Prepare a cutting jig to make outer pillar easier to cut. Also, this will permit service part to be accurately cut at joint position.
 An example of cutting operation using a cutting jig is as follows.
1. Mark cutting lines. A: Cut position of outer pillar
B: Cut position of inner pillar
2. Align cutting line with notch on jig. Clamp jig to pillar.
3. Cut outer pillar along groove of jig. (At position A)
4. Remove jig and cut remaining portions.
5. Cut inner pillar at position B in same manner.
