Disassembly
Thoroughly clean the unit before disassembling.
Scrub all outside surfaces with a stiff brush and
hot, soapy water to prevent surface dirt from con-
taminating internal parts.
Always use a lint free shop cloth when handling
power trim/tilt components.
If painting the unit is required, paint it after it is
completely assembled. Painting of individual com-
ponents may cause flakes of paint to enter the
hydraulic passages during assembly. Tape the
trim/tilt piston rods before painting.

WARNING
Before removing the manual release valve,
operate the unit to the full UP position,
then run the unit down momentarily and
loosen the reservoir cap one full turn.
To avoid personal injury, always wear eye
protection when servicing the hydraulic
unit. Since there might be significant
residual pressure behind some compo-
nents, cover each component with a shop
cloth as you remove it.
CAUTION
Do not apply heat to the cylinder body or
cylinders. Excessive heat can cause high
pressure leaks or failure of parts.
