1. GENERAL

1.1. GENERAL INSTRUCTIONS
Carefully read this manual before installing the gear unit.
Compliance with the instructions will assure long and troublefree operation of
the gear unit.
The equipment should be checked against shipping papers and inspected for
apparent damage sustained during transport. Any shortage, discrepancy or
damage must immediately be reported to HANSEN.
1.1.1. Warranty
The warranty clause of the "General Conditions of Sale" applies to gear units
installed and maintained as per instructions contained in this manual and in
any additional instruction leaflets supplied with the gear unit insofar as the
gear unit operates within the service and rating conditions put forward in the
"Order Acknowledgement" and on the certified drawings.
Non compliance with these instructions, injudicious choice of lubricant or a
lack of maintenance will render warranty agreement invalid.
This warranty clause applies to all parts of the gear unit with the exception of
these parts which are subject to wear.
1.1.2. Safety
!
It is not allowed to use the gear unit for other
applications or in other operating conditions than
the one for which it is ordered.
The user shall be responsible for the proper in-
stallation of the complete equipment and the
supply of protection guards and other safety
equipment in accordance with local safety regu-
lations.
Heaters, coolers, electrical alarms and other safety or monitoring devices
supplied by HANSEN with the equipment must be installed and connected by
the user as indicated on the relative document.
1.2. GENERAL SPECIFICATIONS
For general specifications such as dimensions, weight, connecting diagrams,
refer to certified drawing of the gear unit and/or to the Hansen P4 standard-
ized gear unit catalogues.
1.3. IDENTIFICATION
Inquiries concerning a gear unit should always specify the unit's complete
type code and manufacturing number, which can be found on the name-
plate.
The nameplate, which is fitted on each gear unit, also contains ratings
and/or torque, speed and lubrication instructions.
This information is essential to identify positively the unit supplied by
HANSEN.

2. SHIPPING

Prior to shipment each unit has been inspected and accepted by the QUALITY
CONTROL DEPARTMENT according to order specifications, and after no
load test of several hours in its normal operating position and at speed
indicated on the nameplate.
®
2.1. SHIPPING CONDITIONS
Unless otherwise specified, gear units are shipped in unpacked condition
and depending on necessity, fixed on wooden pallets with open crating
protection. Sometimes parts, such as spare filter elements, are separately
packed. In such events, the end-user must take care of the assembly (see
chapter 5. INSTALLATION p. 5).
The HANSEN P4 gear unit is shipped without oil.
!
All grease lubrication points are factory filled.
2.2. PAINTING
The standard external paint for HANSEN gear units is an epoxy primer with
high solids content, corresponding to the German Standard RAL 5021, water
blue.
This paint system offers a 5 year protection for indoor installation provided
the gear unit is not subjected to humid or chemical aggressive atmospheric
conditions.
Overcoating is possible with most paints based on alkyd-, epoxy or
polyurethane resins.
2.3. PRESERVATION
The inner parts of the gear units are sprayed with rust preventing mineral oil.
The breather plug (standard, dust-proof, anti-humidity) is neither removed nor
sealed.
The shaft extensions are protected with a rust preventing grease and waxed
paraffin paper. The hollow shafts and all unpainted machined surfaces are
coated with an anti-oxidizing waxy varnish.
This standard system offers corrosion protection during transport and/or
storage for up to one year indoors.

3. STORAGE

Always store gear units in their originally sup-
plied shipping conditions.
Gear units should not be stored near vibrating
machines in order to avoid damage to bearings.
3.1. SHORT TERM STORAGE
Up to one year indoors. Always store units in their originally
shipping conditions.
3.2. LONG TERM STORAGE
Max. 5 years indoors or 6 months outdoors.
• The protection should be kept intact if long term storage was specified at
order placement.
• In all other cases the gear unit must be filled with a small amount of
mineral oil containing a volatile corrosion protection additive. All gear
unit openings (dipstick, breather etc.) should be hermetically sealed.
Some additives may be added to the normal oil. Consult your oil
supplier.

4. HANDLING

The Hansen P4 gear units are easy to handle and to install. Make use of in-
tegral oval lifting eyes (horizontal mount) and lifting eye nuts or integral rods
(vertical mount).
For equal load sharing make use of all lifting eyes and use adequate tools.
Lifting eye nuts must not be removed and must
be fully engaged before lifting.
Never lift units with slings wrapped around the
shafts.
Particular circumstances might dictate the temporary removal of thermostat(s),
pressure gauge(s) and/or part of the oil feed piping. After removal of the lat-
ter elements, one should take special care to avoid ingress of moisture,etc...
into the lubrication system of subject gear unit(s).
