3.1 Transport
3. Instructions for Transport and Inspection at Delivery
Never stand under the unit when it is suspended from a crane or similar lifting device; there is a risk of
serious or fatal injuries.
Unpack the unit so that it is taken out the right way up; otherwise there is a risk of injury.
Take care to prevent PARAMAX SFC gear unit from falling over.
When lifting, always use the eye-bolts or holes provided. Use only the appropriate and suciently
dimensioned slings, which should be attached to the eye-bolts provided, or placed around the ange
joints. Screw-in eye-bolts are designed to support only the weight of the drive unit. No additional loads
should be attached.
In general: Do not use the centering holes in the shaft ends for lifting the PARAMAX SFC gear unit using
eye-bolts etc. This can cause damage during storage.
Once the PARAMAX SFC gear unit has been installed in the system, never lift the whole machine using
the suspension hooks or holes; this can cause injuries, damage to the equipment, or damage to the lift-
ing device.
Before lifting, check the weight of the PARAMAX SFC gear unit by referring to the data on/in the packag-
ing, the accompanying drawing, the catalogue, etc. Never lift a unit if its weight exceeds the maximum
permitted load of the crane or lifting device; this can cause injuries, damage to the equipment, or dam-
age to the lifting device.
After Delivery, check whether:
1. The delivery goods correspond to those ordered (see also the descriptions on the model plate).
If there is any doubt that the delivery does not match your order, contact our nearest agency, dealer or
service centre.
2. Any parts have been damaged during transport. Any damage during transport must be reported to
the shipping company immediately. If it has to be assumed that transport damage is going to prevent
correct operation, then startup must be suspended.

4. Storage before StartUp
The PARAMAX SFC gearbox must be stored in a clean dry area, protected by a roof.
The PARAMAX SFC gearbox should not be stored in the open, or in damp areas.
The quality of the oil seal deteriorates when exposed to high temperatures and UV radiation.
After long periods of storage, inspect the oil seal and replace it if there are any signs of damage or
cracking.
After starting the PARAMAX SFC gear unit, check for unusual noises, vibrations or heating. If any
anomalies are found, please contact our nearest agent, dealer or service centre immediately.
Following delivery, put the PARAMAX SFC gear unit into operation for 5 to minutes every 2 to 3
months, using the recommended lubricant. If this is not possible, or if the PARAMAX SFC gear unit is to
be stored for more than 6 months, ll the gearbox with the appropriate quantity of vapor phase inhibi-
tor (JIS NP20 or equivalent product), following the recommendations of the product manufacturer.
5. Installation of the Paramax SFC Transmission
5.1 Required Aids
- Wrench set
- Torque wrench for mounting bolts on foot/ange housing, motor lanterns, clamp couplings etc.
- Retractor
- Compensating elements
- Corrosion protection (e.g. MoS2 paste, Molykote, copper paste)
The corrosion protection applied to shaft ends, hollow shafts and centering seats during storage and
transport must be removed before startup. The corrosion protection can be removed using an alkaline
solvent. Never use mechanical methods for removal (e.g. abrasive materials etc.). The alkaline solvent
should not be allowed to come into contact with the seals.
When handling lubricants, solvents and anti-corrosion agents, follow the human and environmental
safety instructions given on the corresponding DIN 52 900 safety data sheets.
4.1 Long-Term Storage
If the PARAMAX SFC gear unit is tted with a reverse lock and is being left out of operation for a long
period, the unit should be started for at least 5 minutes every 200 hours.

The drive unit is to be set up so that inspection, maintenance, and other operations such as lubricant
top-ups, can be carried out easily.
In order to prevent overheating and risk of re, ventilation of the PARAMAX SFC gearbox should not be
obstructed.
Tighten the mounting bolts to the specied torque only after carefully establishing perfect evenness
over the entire surface of the mounting base, which should provide torsional stiness and vibration
damping, and after aligning the drive. After about 4 weeks, all mounting bolts should be checked again
to ensure the correct tightening torque.
We recommend using mounting bolts of DIN quality 10.9.
If the drive is to be loaded up to maximum output torque or maximum transverse force, positive-t con-
nections (e.g. DIN 6325 cylinder pins) should be provided in addition to the foot mounting bolts.
5.2 Installation
Table 1 Mounting screw torques
* Screw class ISO 898-1/8.8
Mos2 paste is recommended for preventing electrochemical corrosion between the PARAMAX SFC gear
and the work machine when dierent metals are connected together, for example cast iron and stainless
steel.
The housing should also be grounded, using the grounding screws on the motor.
If the drive is to be painted over or partially re-nished, rst ensure that the vent valve and shaft seals
are carefully masked o. Remove the masking tape after the painting work is completed.
PARAMAX SFC gear units should not be used for any purposes other than those indicated on the model
plate or in the manufacturer’s documentation; otherwise there is a risk of electric shocks, injuries, or
damage to the equipment.
Do not place any inammable objects near the unit, otherwise there is a risk of re.
Do not place near the PARAMAX SFC gear unit any objects that obstruct the ventilation. Insucient ven-
tilation can lead to overheating, and therefore a risk of burning or re.
Do not step on or hold onto the PARAMAX SFC gear unit, as this may cause injuries.

Do not touch the shaft end of the PARAMAX SFC gearbox, or the inner gearing, or the edges of the mo-
tor fan with bare hands, otherwise there is a risk of injury.
If the unit is used in food processing applications where there is a risk of oil contamination, install an oil
pan or similar device to collect any oil leaks if there is a stoppage or equipment failure. Food products
may be contaminated by oil leakage.
Damaged systems should be switched o immediately and not put back into operation until they have
been repaired.
If any modications are made to the system, or non-original spare parts are used, then the warranty is
void and no liability can be accepted.
The installation angle should be within the limits indicated below.
Fig.2
Limit values for installation angle
Standard units in the PARAMAX SFC gears and gear motors should not be used in areas where there is a
risk of explosion (ATEX).
In conditions like this, the special explosion-proof PARAMAX SFC gear unit should be used. Otherwise
there is a risk of electric shocks, injuries, explosions or damage to equipment (see Section 14.).
Since the converter itself is not explosion-proof, converter-driven motors (even though they themselves
may be explosion-proof) should be set up only in an environment that is free of explosive gas mixtures
or dust concentrations: otherwise there is a risk of electric shocks, injuries, explosions or damage to
equipment, and even physical injuries.

6. Connection to other Machines
Ambient Air Humidity: max. 100 %
Height: max. 1000 m above sea level
Ambient Air: should be free of corrosive or explosive gases, and vapor. (Applications in ATEX are pos-
sible if agreement is obtained from the factory. (See Section 14.)
Assembly: Interior or exterior location
Ambient Temperature: 0°C to +40°C
Approval should be obtained from the factory if operating in ambient temperatures below 0 C or
above +40 C.
If an oil heater is used (ambient temperature -15 C), it must have a voltage present continuously.
An integrated thermostat starts the oil heater when necessary.
Cover rotating parts with suitable protective devices; otherwise there is a risk of injury.
Check the direction of rotation before connecting the PARAMAX SFC gear unit to a drive motor. An unex-
pected direction of rotation can cause injuries or damage to the system, especially if a reverse lock is
installed.
Check the direction of rotation of the connected motor. If the directions of rotation are dierent, there is
a risk of injuries, or damage to the machine.
If the PARAMAX SFC gear unit is coupled to a load, check to ensure that any deviations in alignment
are within the limits indicated on the drawings and in the catalogue. Otherwise the misalignment may
cause damage to the system.
Tighten the bolts correctly to the specied torque, otherwise cooling tower systems may be damaged or
personnel injured by ying parts.
If the output shaft of the PARAMAX SFC gear unit is to be left to turn freely (i.e. without load), rst re-
move the feather key; otherwise there is a risk of injury.
6.1 Attaching a Coupling Element
When attaching a coupling element, check that there are no impact forces or excessive pressure forces
acting on the shaft; otherwise the bearing may be damaged.
The coupling is produced by means of a shrink-t, or a thread connection tted to the shaft end (Fig. 8).
