4) Remove the oil tank cap. Check that Automatic
Transmission Fluid (ATF) is at the upper limit of the filler
port (P. 15-47).
5) Push the "DN" side of the power tilt switch to compress
each rod fully. Read the pressure gauge to measure the
upper chamber blow pressure.

blow pressure
6) If the blow pressure is lower than the specified pressure,
check each part of the power trim/tilt assembly for oil
leakage.
7) If there is no oil leakage but the pressure dropped sharp
below the specification, check the power tilt motor
assembly for the damaged oil seal. Disassemble the power
tilt motor assembly (P. 15-53) and inspect (P. 15-55), and
measure the upper chamber blow pressure again (P. 15-50).
8) After checking, push the "UP" side of the power tilt switch
and move each rod to the fully extended position.
9) Remove the special tool (oil pressure gauge joint A) and the
pressure gauge.
10) Tighten the manual valve to the specified torque.
TORQUE: 3.5 N . m (0.35 kgf . m, 2.5 lbf . ft)
11) With each rod in the fully extended position, remove the oil
tank cap and check that the Automatic Transmission Fluid
(ATF) is at the upper limit of the oil filler port (P. 15-47).
If the Automatic Transmission Fluid (ATF) does not flow out
of the oil filler port, add the Automatic Transmission Fluid
(ATF) up to the upper limit of the oil tank using a syringe or
equivalent tool (P. 15-47).
