1.2.2
Clean Working Conditions
Caution
Hydraulic oil damages paint. Immediately remove any hydraul‐
ic oil that has come in contact with painted surfaces.
♦ Clean connecting points and surrounding areas before loos‐
ening.
♦ Place removed parts on a clean surface and cover. Use foil
and paper. Do not use cloths with lint!
♦ Carefully cover or seal opened components if the repair will
not be done immediately.
♦ Only install clean parts: remove replacement parts from the
packaging immediately prior to installation.
♦ Place collecting container or foil and cloths under connections
to be opened so that hydraulic oil does not come into contact
with painted surfaces.
♦ Seal open hydraulic lines with cover caps to prevent hydraulic
oil from leaking out.
1.2.3
Hydraulic System, Filling and Bleeding
Note
The electro-hydraulic convertible top operation involves a
♦
closed hydraulic system. Generally, filling is necessary after a
loss of oil (accident, leaks, etc.).
Due to the lift and displacement effect of the pistons in the
♦
hydraulic cylinders, the hydraulic system must be filled when
the convertible top is stored in the compartment.
After filling, convertible top must then be moved several times
♦
using the electro-hydraulic operation.
Then check the oil level again and correct if necessary.
♦
Caution
Do not fill system above "MAX" marking as the pressure in the
system can become so great that damage can result.
1.2.4
Hydraulic System Assembly Overview
Caution
♦ Before working on the hydraulic system, the valve on the
hydraulic pump must first be opened.
♦ With all work where the hydraulic circuit must be opened,
the corresponding seals must always be replaced.
