1. Fully tilt up the outboard motor and lock it with the tilt
stopper 1.
2. Remove the cap 2 and check the amount of fluid in the
reserve tank.

the tilt stopper after tilting up the motor.
Leaving the outboard motor up without
locking may lead to accidental descent
due to the reduction of PT unit hydraulic
pressure, which is dangerous.

Check the fluid level with the outboard
motor fully tilted up. When the reserve tank
cap is removed at the halfway position, it is
not possible to check the specified amount
of fluid, and the PT fluid may start to spray
out, which is dangerous.
6. Let stand for 5 minutes to allow the PT fluid to stabilize.
7. Operate the PT switch to check that the outboard motor
tilts up fully.
9. Remove the cap 2 and check the amount of fluid in the
reserve tank.
8. Lock the outboard motor with the tilt stopper 1.
The specified amount of fluid is about the amount
that overflows from the level hole when the cap is
removed.
When not tilted up to full tilt, loosen the manual
valve and tilt up manually and lock with the tilt
stopper.
