LZB14-L-A007-11 ATEX
IP Rating
The IP Rating of the air motors is set under pressurized con-
dition and excludes the outlet or attached silencer. If the mo-
tor will operate submerged or in heavy water jets, it's recom-
mended to lead the outlet away from water with a hose.
When submerged, always keep the motor pressurized with a
higher pressure than the corresponding depth.
Connecting the air supply
When the compressed air supply is connected to the inlet, the
direction of rotation will be as shown in the figure below. If
the exhaust air is to be piped away, a hose should be con-
nected to the exhaust outlet.

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
used for the purpose for which they were designed.
For product liability and safety reasons any modification to
the motor or its accessories, which may have an influence on
the product liability, must be agreed upon by the technical
authority of the manufacturer.
To prevent personal injury and long term risks:
• If the motor is ATEX-certified, filter/silencers must be
installed at the motor outlet ports.
Silencers are recommended also for other applications to
reduce noise exposure.
• Disconnect the motor from the air line before any adjust-
ment operation.
• Mind your hands, hair and clothing – always keep
well away from rotating parts.
Maintenance
• Maintenance and repairs of this ATEX product must be
carried out exclusively by authorised personnel, after
which a no-load test and temperature measurements of
hotspots (as seen in the figure) must be carried out and
recorded in a report.
After a 5 min no-load test the surface temperature must
not exceed the sum of 45°C + surrounding temperature,
where the surrounding temperature can vary between 0 –
40°C.
