1.4.12 BODY HOISTING SYSTEM
MAINTENANCE
The OPTIMIZER
TM
is equipped with a hoisting
system used to raised the body. This system
is fed by its own hydraulic pump (see Figure
#1.21.
Since this pump is energized by electrical
cables, it is protected by a cover.
The pump of the body hoisting system must
be adjusted to 2000 PSI.
To do so, proceed with the following steps:
• Install a 3000PSI pressure gauge on
the quick coupling found on the
pump (see Figure #1.21).
• By using the pump manual lever
(see Figure #1.22), raise the body
until the mechanism reaches the
end of its stroke.
• Check the pressure while the body
is held fully raised.
