Shaft load diagram

Hot Spots

The following hot spots on the motor can reach high temper-
atures during operation. The image shows hot spots for spe-
cific models:
• Seal ring at the output shaft (A, B, C)
• Joint between front part and gear ring (A, B)
• Key grip (A, B)
The highest temperatures occur when the motor is running at
full pressure without load. With increasing torque, the air
motor reduces the rotational speed and the temperature.
Warning
Make sure you are familiar with the operating instructions
before you use this motor.
This motor, its attachments and accessories must only be

ment operation.
• Mind your hands, hair and clothing – always keep
well away from rotating parts.
