PRECAUTIONS

Never weld aluminum die-casting parts, made of heat-treated materials, for crack repairs, etc. Otherwise, the strength of these parts reduced by the welding heat.
Never hammer aluminum die-casting parts, if these parts are deformed. Replace them as an assembly.

If the vehicle is damaged, visually inspect aluminum die-casting parts for deformation and carry out the crack inspection.
This inspection is carried out using dye penetrant testing agents (cleaning solution, penetrant liquid, and developer).
 

Joining these parts and steel plated parts directly may cause electric corrosion. Coat the joint surface with epoxy primer to prevent electric corrosion.

■ CAUTION ■

Clean the joint surface thoroughly to eliminate iron powder first. Then apply the specified adhesive to bond the parts.
Never use bolts other than those that are specified, otherwise electric corrosion occurs. Always use the specified bolt with its surface appropriately finished.
Never reuse the removed specified bolt. Because the surface treatment may peel off, once the bolt is loosened.

Because aluminum parts are soft, it is necessary to tighten the parts to specified torques.
Always use a torque wrench when tightening a part to the specified torque.

■ WARNING ■

Never use an impact wrench to remove or install the bolts.

• For steel plate tools, distinguish the special tool for aluminum alloy and the tool for steel plate.
• The cutting blade or sandpaper is specified for aluminum alloy. Distinguish them from the part for steel plate.
• When the wire brush is used for the aluminum alloy parts, use the stainless-steel wire and never use the steel wire.
