parts in their respective groups (i.e., intake, exhaust, No.1
or No.2) so that they can be installed in their original
locations.

PAIR VALVE

PAIR REED VALVE
• Remove the PAIR valve cover.
• Inspect the reed valve for the carbon deposit.
• If the carbon deposit is found in the reed valve, replace the
PAIR control valve with a new one.
PAIR CONTROL VALVE
• Inspect that air flows through the PAIR control valve air inlet
port to the air outlet ports.
• If air does not flow out, replace the PAIR valve with a new one.
• Connect the vacuum pump gauge to the vacuum port of the
control valve as shown in the photograph.
• Apply negative pressure of the specification slowly to the con-
trol valve and inspect the air flow.
• If air does not flow out, the control valve is in normal condition.
• If the control valve does not function within the specification,
replace the control valve with a new one.
