»To check that the air motor is designed for use
in hazardous applications read the air motor
label:
»Hazardous zone
»Hazardous category
»Equipment group
»Temperature class
»Maximum surface temperatures
»Check the air motor before installation and
operation to see if it’s not damaged.
»Any products that are driven by the air motor
must meet appropriate ATEX approval as well
to be used in a hazardous area.
»The air motor should be connected to the
earth with a maximum earth resistance of
1Mohm. The motor can be earthed by con-
necting the motor to a base plate/gearbox
etc.
»The ambient temperature range of the motor
(-20°C to +60°C) should be observed at all
times.
»When mounting the engine on a construction
or when something is mounted on the shaft of
the air motor. Make sure that the alignment is
straight to prevent too much force on the shaft.
»An air filter should be placed in the airline
with at least 64 micron near the air motor.
»Clean surface of air motor unit thoroughly of
all dustproofing products, contaminants and
other impurities. Do this outside the hazardous
area or clean only with a damp cloth.
»A lubricator must be placed inside the main
airline near the motor. The lubricator unit
should have a bowl with enough oil for
operation and should allow the user to control
the amount of oil drop per minute going to
the motor.
»Check airline oil every time before starting.
Air motor should be supplied with oil of a
viscosity of 32. This type of oil is flammable at
a temperature of 218°C.
»Air supply to the motor should always be
taken from non-hazardous area.
»In case the motor is exposed to high vibrati-
ons during operation and when not in ope-
ration, please contact the manufacturer. High
vibrations might lead to increased inspection
interval of the bearings.
»It’s important that no dust or debris can accu-
mulate at the output shaft. This may damage
the shaft seal. If the motor is built in a closed
system or construction so that no dust or
debris can get in contact with the output shaft
the air motor can be used in any orientation.
If the motor is used is such way that the output
shaft is in contact with explosive environment
the mounting position is limited from horizon-
tal to vertical downwards. It is not allowed for
the shaft to point in any angle upwards.
Checklist to comply to ATEX:
WARNING: POTENTIAL ELECTROSTATIC CHARGING HAZARD
Before use clean only with damp cloth. Avoid electrostatic charging mechanisms
stronger than manual rubbing. Do not subject the equipment to external conditions
that could cause build-up of electrostatic charges.

»Air supply to the motor should always be
taken from non-hazardous area.
»Remove the plastic shipping plugs from the
ports. Save the plugs for the future, during
shutdown.
»Please make sure that the temperature of the
air used for air supply to the air motor don’t
exceed the following temperatures, -20°C to
+40°C.
»Install a filter (64 micron) to make sure the air
is clean and dry and install an air pressure
regulator to control motor speed and torque.
»A lubricator must be placed inside the main
airline near the motor. The lubricator unit
should have a bowl with enough oil for ope-
ration and should allow the user to control
the amount of oil drop per minute going to
the motor. Check airline oil every time before
starting. Air motor should be supplied with
oil of a viscosity of 32. This type of oil is
flammable at a temperature of 218°C.
»Air quality should meet ISO 8573-1:2010
class 4 for solid particles and ISO 8473-
1:2010 class 3 for water.
»For the most efficient power and control of
speed, all valves and the airlines should be
the same size as the air connections of the
motor. If the valves, airlines and other con-
nections have a longer distance than 2m (6
feet) of the motor we advise one size bigger.
»Before final connection to the motor, clean
the compressed air connection with low
pressure air to remove any dirt inside the
line before connecting to the ports of the air
motor.
»A silencer is supplied with the motor. When
installed ensure that condensation cannot run
back into the motor port. Mount the air motor
with silencer pointed down or make extra
piping on the silencer.
»If the motor unit is not used for a longer
period it is advisable to store the unit indoors
remove the silencer and plug the exhaust
port. See also shut down and long storage at
maintenance.
