WARNING!
Risk of injury due to moving parts!
Before switching on the drive, check the following:
Are no persons in danger due to start-up?
Is all protection and safety equipment properly installed,
in test operation too?
Is the drive not blocked?
Are the brakes released?
Is the direction of rotation of the drive correct?
Are components attached to the output such as feather
keys or coupling elements adequately secured against
centrifugal forces?
6.2 During commissioning
As the operating conditions for gear units are very different, it
must be ensured for safe operation under maximum operat-
ing conditions that the surface temperature of the gear unit
does not exceed the maximum permitted value. For this pur-
pose, take the following measurement with a standard com-
mercial temperature measurement device.
Determine the surface temperature at the gear unit/motor
transition where the terminal box position prevents ventilation
by the motor fan.
For gear units with a motor adapter or free drive shaft, deter-
mine the surface temperature at the joining seam between
the gear unit flange on the input side and the attachments.
The maximum surface temperature is reached after approx. 3
hours under full load and may not exceed the maximum value
of 90° C for the highest surrounding temperature. Stop the
drive immediately if the maximum value is exceeded and con-
tact STOBER Service.

7.1 Inspection and maintenance
To ensure safe operation with regard to explosion protection,
carry out the following inspections and maintenance work at
the specified intervals:
Daily or according to dust accumulation
•
Remove dust deposits from the gear unit surface (STOB-
ER recommends removing dust deposits with a thickness
of 1 mm or more)
•
If present, check rubber buffer of the torque arm and re-
place if wear or damage is detected
Every 500 operating hours, every 3 months at the latest
•
Visually check the shaft seal rings for leaks
•
Check operating noise for possible bearing damage
Every 5000 operating hours, every 5 years at the latest
•
Replace lubricant
•
Replace shaft seal rings
Every 10000 operating hours
•
Replace rolling bearing
Comply with the lubricant specification and amount that is
stated on the nameplate of the gear unit when changing the
lubricant. Do not mix lubricants with different specifications.
7.2 In the event of disruptions
Changes compared to normal operation indicate that the
function of the drive has been impaired. This includes:
•
Higher power consumption, temperatures or vibrations
•
Unusual noises or odors
•
Leaks on the gear unit
•
Monitoring devices responding
In this case, stop the drive as quickly as possible and contact
STOBER Service.
