u Does the motor turn over when the battery is directly connected?
CH
• Disconnect the blue lead and green lead of the PT&T and touch the plugs against the red and black
lead terminals, respectively. Operation is normal if the blue-to-red and green-to-black contacts
move the motor up and the blue-to-black and green-to-red contacts move the motor down.
• Disconnect the PT&T cable from the engine cover and touch the end against the battery terminal. If
this does not activate the motor is defective.
i Check the electrical wiring system for leaking connectors, electrical shorts and severed lines.
CH
• With the focus on the various cables, check for electrical shorts.
• Also check the various switches for damaged cables.
o Are there any signs of oil leakage?
CH
• Conduct an external visual check for oil leakage.
To check for minor leaks, operate the PT&T unit and look for signs of oil leakage on the
surrounding water's surface.
• In cases where oil leaks are discovered in the PT&T unit or the cylinder, it will be necessary to
conduct a disassembly test to check for damage. Repair as necessary.
!0 Is the manual valve closed properly?
CH
• Firmly close the manual valve.
Direction: clockwise, torque: 2 to 3 N-m (0.2 to 0.3 kg-m, 17 to 26 lb-in)
!1 Is oil level normal?
CH
• Check the oil level.
The oil level should be even with the bottom of the oil plug hole when the engine is tilted up (piston
rods are fully extended).
Note: Always make sure to bleed air from the lines and check oil level once more after replenishing oil.
• Refer to CH !3 for description of air bleeding procedure.
• Be sure to use the specified oil (Japan Oil ATF Dexron).
