1.1 Introduction
1.1.1 CUSTOMER'S
RESPONSIBILITY
The Customer/Operator is responsi-
ble to perform the necessary safety
checks to ensure that lubrication, cool-
ing, maintenance and recommended
practices are strictly followed for safe,
enjoyable operation.
All Transmission units are covered by
a guarantee. Therefore: In respect to
the handling of the transmission units
the instructions stated in this manual
are to be strictly followed.
CAUTION
The manufacturer is not liable for
any damages or losses caused by
faulty installation, wrong handling
of the equipment and/or deficient
maintenance.
The Customer has to make sure,
that any external forces, as well
as vibration caused by torsion and
bending, are avoided.
The interaction between engine,
shaft and propeller may lead to
torsional vibration, producing a
hammering noise of gears and
might damage the engine and/or
transmission.
The Supplier is not liable for such
torsional vibration inherent to the
installation.
This manual includes, among others,
the following three main chapters:

3.1 Description
The ZF / ZFE A/H/IV marine trans-
mission is a hydraulically activated
helical gear unit, developed for use in
commercial and pleasurecraft and de-
signed as a three shaft type gearbox.
(Four shafts design for IV type).
The transmission is provided with a
disc-type reversing clutch mounted
on the input shaft and supplied with
hydraulic pressure from a fluid pump.
Operation of the fluid pump is depend-
ent on the engine speed; the pump is
integrated in the control block.
The transmission is lubricated by
splash and force-feed lubrication.
3.1.1 ZFE OPTION
A head, astern, clutch disengagement
are operated electrically by ON/OFF
electric valves.
Electronic control block includes «get
home» features as well.
A simple mechanical device permits
manual engagement of the clutch.
