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 fire, ventilation of the PARAMAX SFC gearbox should not be
obstructed.
Tighten the mounting bolts to the specified torque only after carefully establishing perfect evenness
over the entire surface of the mounting base, which should provide torsional stiffness 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-fit con-
nections (e.g. DIN 6325 cylinder pins) should be provided in addition to the foot mounting bolts.

Mos2 paste is recommended for preventing electrochemical corrosion between the PARAMAX SFC gear
and the work machine when different 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-finished, first ensure that the vent valve and shaft seals
are carefully masked off. 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 inflammable objects near the unit, otherwise there is a risk of fire.
Do not place near the PARAMAX SFC gear unit any objects that obstruct the ventilation. Insufficient ven-
tilation can lead to overheating, and therefore a risk of burning or fire.
Do not step on or hold onto the PARAMAX SFC gear unit, as this may cause injuries.
