tor, remove them.

• When installing the insulator avoid large gaps or interference between the insulator and each

exhaust pipe.

• Remove deposits from the sealing surface of each connection. Connect them securely to avoid gas

leakage.

• If it is difficult to install mounting rubber, use mild detergent for smooth installation.
• When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/left

directions.

• Temporarily tighten mounting nuts. Check each part for unusual interference, and then tighten them

to the specified torque.
