Safety instructions

!
– Please read through these instructions thoroughly before starting the motor and then follow them
precisely during operation.
– Motor and accessories may not be used for other purposes.
– For reasons to do with product liability and operating safety, all changes made to the motor and / or
accessories must be approved by the manu facturer's corresponding technician.
– No liability is assumed for damage caused by failure to comply with the instructions or improper repairs,
together with the use of not original spare parts.
– Subject to modifications in the interest of technical progress.
1.1 Using the motor
– Standard motors may not be used in potentially explosive areas. Please read "Explosion-proof
compressed air motors (in accordance with ATEX guidelines for certified motors)" for these areas.
1.2 To avoid injuries and damage, please note:
– Always disconnect the motor from the compressed air pipe before changing the motor adjustments /
settings!
– Protect your hands, hair and clothing from getting trapped by rotating parts.
– Use suitable filters or silencers to reduce noise development. Here we recommend various silencers
which can be purchased from us.
1.3 Temperatures
– During operation some hotspots on the motor (motor housing, seal ring at the output shaft) can reach
high temperatures. The highest temperatures occur when the motor is running at full pressure without
load. With increasing torque, the motor reduces the rotational speed and the temperature.
2 Instructions and installation
2.1 Air quality and connection conditions
– The motor may only be operated up to a max. flow pressure of 7 bar. Pipe length max. 3 m. Always note
the resulting pressure loss from overlong pipes.
– Always ensure that clean, dry compressed air is used. Provide prescribed air quality as per DIN ISO 8573-1,
quality class 4.
– Use a maintenance unit mounted as close as possible to the motor. Adjust the oil supply quantity to
1 – 2 drops per 1 m³ air volume (1 drop = 15 mm³) per minute. We recommend using an oil spray device
or maintenance unit from MANNESMANN DEMAG.
– Pay attention to the correct inner diameter of the compressed air pipe! Also consult the technical data
for the motor.
– Before connecting the motor, the compressed air pipe (hose) should be blown through thoroughly to
remove any possible dirt particles.
– Before connecting the motor, check the water level in your compressed air. Water, corrosion etc. in the
pipes can cause rust in the motor and thus high motor wear or failure.
– Attach the motor to the flange or to the provided clamping range.
2.1.1 Lubricants
– As lubricating oil: Resin- and acid-free oil in viscosity class HL 32.
– As lubricating grease: Multi-purpose grease for roller bearings, plain bearings and gears, resin- and
acid-free. NLGI class: 2 | Saponification: Lithium | Drop point: 185° C | Worked penetration: 265 – 295
Applications in the food industry:
– Food oil: Oil that complies to USDA-H1 or FDA 178.3570 viscosity class 32
– Lubricating grease: USDA-H1 or FDA 178.3570, NLGI class: 2 – DIN 51818
