C: CAUTION
• Wear working clothing, including a cap, protec-
tive goggles, and protective shoes during opera-
tion.
• Remove contamination including dirt and corro-
sion before removal, installation, and disassembly.
• Keep the disassembled parts in order and pro-
tect them from dust or dirt.
• Until the oil pan is removed, do not place with the
oil pan side facing up to prevent foreign matter from
entering the valve body.
• Before removal, installation or disassembly, be
sure to clarify the failure. Avoid unnecessary re-
moval, installation, disassembly and replacement.
• When disassembling the case and other light al-
loy parts, use a plastic hammer to force it apart. Do
not pry it apart with a screwdriver or other tool.
• Be careful not to burn your hands, because each
part on the vehicle is hot after running.
