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.

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.

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.

During operation, keep at a safe distance from rotating parts (output shaft, etc.) and/or avoid touching
them. Loose clothing can get caught up, causing serious or even fatal injuries.
If the power supply is interrupted, set the main switch to OFF. If power is restored unexpectedly, this can
cause electric shocks, injuries, or damage to the equipment.
Do not place ngers or any other foreign objects at the opening to the gear motor of the PARAMAX SFC
gear unit. This can cause electric shocks, injuries, risk of re or damage to the equipment.
Never loosen the oil ller screw during operation, as hot oil spray may cause burn injuries.
If any anomalies occur during operation, switch o the unit immediately. Otherwise there is a risk of re,
burn injuries, or damage to the PARAMAX SFC gear unit.
PARAMAX SFC Gear Unit are Supplied without Oil. All Units must be Filled with the Required
Quantity of oil Before the Initial StartUp.
If any abnormalities are found, stop the unit immediately and contact our nearest agent, dealer or sales
centre.
8. Starting up the Drive and Operation
Oil Filling/Checking the Oil Level
Add oil through the ller neck at the top of the main unit, checking the oil
level with an oil gauge (see Fig. 5).
Filter the oil before lling.
During oil-lling, take care to ensure that no loose nuts, bolts, washers,
dust, water or other foreign objects are allowed to enter the unit.
If the oil level is below the specied range, then there is insucient lubri-
cation. If the oil level is above the range, then loss of oil quality is acceler-
ated due to the rise in oil temperature.
Oil Change and Used Oil
Remove the oil drain plug at the bottom of the main unit to drain o the
oil while it is still warm (i.e. shortly after the unit is put out of operation,
but not immediately after.) Please dispose used oil according to rules of
environmental protection.
Please pay also attention to chapters 10.1 and 14.
The oil level
must be
within this
range

9.1 Lubricant - Initial Filling, Top-Ups and Changes
Table 7 Initial oil lling, replacement with mineral oil
* according to which occurs rst.
Deterioration of the oil quality accelerates if there is rapid variation of the ambient temperature, or the
ambient atmosphere contains corrosive gases. In these cases, please contact the lubricant manufacturer
for more information.
Oil changes as indicated in Table 7, depending on which time occurs rst.
If the system is equipped with a motor pump, the motor for the pump must be started before starting
the gear motor or PARAMAX SFC drive unit. After lubricating oil is circulated through the bearings, start
the gear motor or PARAMAX SFC drive unit; otherwise there may
be damage to the system.
Use a ow switch or inspection glass to check the oil ow. If any irregularities are occurring, stop the
gear motor or PARAMAX SFC gear unit motor immediately.
10. Inspection Intervals
10.1. Inspection and Maintenance Instructions
Do not touch the unit when live. Always switch o the power supply rst; otherwise there is a danger of
electric shock and injuries due to rotating parts.
During maintenance or inspection, keep away from rotating parts (output shaft, etc.), and do not touch
them. Loose clothing can get caught up, causing serious or even fatal injuries.
Never place ngers or any other foreign objects at the opening to the SFC transmission. This can cause
electric shocks, injuries, risk of re or damage to the equipment.
The gear motor and/or SFC transmission become extremely hot during operation. Touching the unit
with bare hands may result in serious burn injuries.
Never operate the unit with the protective cover removed; loose clothing can get caught up, causing
serious or even fatal injuries.
Any anomalies observed during operation must be immediately identied and corrected according to
the instructions in this operating manual. Do not restart operation until the anomaly has been cor-
rected.
Oil change intervals Operating conditions
Initial lling Before startup -------
1. Oil change Up to 500 hours or 6 months* -------
2. Oil change Every 4000 hours or 6 months* -------
Every 8000 hours or once per year* If operated at oil temperature of < 80°C

The lubricants are to be replaced as indicated in the operating instructions. Always use the lubricant
recommended by the manufacturer.
Lubricants must never be replaced during operation or shortly afterwards; otherwise there is a risk of
burn injuries. Before being changed, the lubricant must be allowed to settle.
Never use the PARAMAX SFC gear unit if damaged; otherwise there is a risk of injuries, re, or damage to
the equipment.
We cannot accept any liability for damage or injuries that result from unauthorized modication of the
equipment by the customer.
Used lubricants from the PARAMAX SFC gear unit are to be disposed of as industrial waste. Please follow
the applicable local regulations.
To ensure correct and optimal operation at all times, carry out daily inspections as indicated in Table 8.
10.2 Daily Inspections
If any anomalies are found during daily inspection, these must be corrected as described at Point 13
“Fault repair”. If it is not possible to correct the anomaly, please contact our nearest agent, dealer, or
sales oce.
10.3 Yearly Inspections
To Inspect the Gears:
- Drain the oil
- Loosen the mounting bolts on the inspection cover
- Check the gear teeth visually for pitting and wear
- When placing the inspection cover, check that the sealing surfaces are clean
- Replace damaged seals
- Tighten the bolts (8.8) to the correct torque
- Oil lling
- Check for leaks after startup
Table 8
Noise Are there any unusual noises during operation, or does the sound
suddenly change?
Vibration Are there unusually strong vibrations, or do the vibrations suddenly
change?
Surface temperature
Is the surface temperature abnormally high, or is there a sudden rise in
temperature?
The increase in temperature varies according to the transmission type.
Surface temperature should be around 80°C (176°F) maximum.
Oil level
Is the oil level falling?
Check the oil level when the transmission is switched o, using the
dipstick or oil level gauge.
Oil loss Is any oil leaking from the oil seal or other sections?
Anchor bolts Check that the bolts are rmly seated.
Yearly inspection
Gears Examine the gears to check for damage
Inner case of gearbox Check if contaminated with sludge or abrasives
and clean if indicated by oil ush

Explosive gas mixtures or dust concentrations, when combined with the hot, live and moving parts
in the PARAMAX SFC gear unit, may lead to serious damage to equipment and physical or even fatal
injuries.
Standard units in the PARAMAX SFC gears and gear motors should not be used in areas where there is a
risk of explosion.
In conditions like this, the special explosion-proof PARAMAX SFC gear units should be used.
PARAMAX SFC gear units that are ATEX-certied always carry the ATEX mark. The ATEX mark is located
on the model plate (see Section 11.2).
The assembly, connection, startup, maintenance and repair work on the PARAMAX SFCgear unit, and
additional electrical ttings should be carried out only by qualied technical personnel, taking account
of:
- These instructions.
- The warning and information signs on the PARAMAX SFC transmission.
- All other design documents and circuit diagrams related to the drive.
- The system-specic regulations and requirements.
- National/regional standards and regulations (regarding explosion protection, safety, accident preven-
tion).
- Dust deposits should be no thicker than 1 mm and should be removed where necessary.
- The customer’s installed conguration should not obstruct the heat ow from the PARAMAX SFC gear
unit due to convection and heat conduction.
- Operation with excessive loads is not permitted.
- External heat inputs into the PARAMAX SFC gear unit are not permitted.
- Oil temperature should not exceed.
- The drive rotational speed should not go above 1800 rpm.
- All electrical and mechanical components attached to the PARAMAX SFC gear unit must be accompa-
nied by an ATEX certificate.
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.
11 Special Instructions for ATEX approved PARAMAX SFC Transmissions and Gear Motors
11.1. Safety Instructions applying to ATEX Areas
If damage to the gears is found, and operation can therefore not be ensured until the next maintenance
interval, please obtain the corresponding original spare parts. Gears to be replaced in sets. We recom-
mend also replacing the corresponding roller bearings and seals at the same time.

Where possible, the gearbox is to be started when not under load. If it is running smoothly with no
abnormal noises, the PARAMAX SFC unit can be loaded with the work machine.
After about 3 hours, measure the surface temperature. Check the maximum permissible dierence
relative to ambient temperature. If the dierence is greater than the value indicated for the model con-
cerned, stop the drive immediately and contact Sumitomo Drive Technologies.
Damaged systems must be switched o immediately and should not be put back in operation until
they have been repaired.
If any modications are made to the system or non-original parts are used, the
warranty is invalid and no liability can be accepted.
Do not remove the model plate.
- Does the data on the model plate on the gearbox or gear motor correspond to the required ATEX
operating conditions at the site?
- Does the model plate show the correct data?
- Is the drive undamaged (check for any shipping damage/damage during storage)?
- Is there an unobstructed ow of cooling air? Is any hot exhaust air being drawn in from any other as-
semblies? The cooling air temperature should not exceed 40°C.
- Are all input/output drive elements ATEX-approved, and identied with the correct designation?
