MHD56208 - Edition 3 7
Air Line Filter
Refer to Dwg. MHP0191 on page 7.
Place strainer/filter as close as practical to motor air inlet port, but
upstream from lubricator, to prevent dirt from entering motor. The
filter/strainer should provide 50 micron filtration and include a
moisture trap. Clean the filter/strainer periodically, as experience
dictates, to maintain its operating efficiency. Refer to
manufacturer’s literature for cleaning/replacing recommendations.
Air Pressure Regulator
Refer to Dwg. MHP0191 on page 7.
If an air pressure regulator is used, install between lubricator and
filter as shown.
Moisture in Air Lines
Moisture that reaches air motor through air supply lines provides
piston rings lubrication. Over prolonged periods of operation,
depending upon moisture content in the air, water will build up in
bottom of motor housing. This accumulation must be drained to
maximize bearing life. Refer to ‘Draining Motor Housing’ on
page 8 in the “OPERATION” section.
(Dwg. MHP0191)
Mufflers
Ensure muffler is installed in at least one exhaust port on rotary
housing. The motor rotary housing has two exhaust ports.
Installation of two mufflers in rotary housing is optional. Check
mufflers periodically to ensure they are functioning correctly.
Natural Gas Operation (optional feature)
• Ensure all fittings and connections are tight. Inspect all
connections with suitable leak detection equipment.
• At first notice of any unusual odors or noticeable leaks, cease
motor operation until source is identified and corrected.
• Natural gas exhaust must be piped away from motor.
• All motor control options are required to be natural gas
compliant.
The MMP150 motor may be run using natural gas. However,
motor modifications are required for this usage. Refer to parts
section for additional information.
Use of natural gas will reduce motor life.
Natural gas exhausting from the motor must be piped away.

Initial Motor Operating Checks
Motors are tested for proper operation prior to leaving factory.
Before motor is placed into service the following initial operating
checks should be performed.
1.
When first running motor, inject light oil into inlet
connection to provide initial lubrication.
2. When first operating, it is recommended that motor be driven
slowly in both directions for a few minutes.
For motors that have been in storage the following start-up
procedures are required.
1. Give motor an inspection conforming to the requirements of
‘Motors Not in Regular Use’ in “INSPECTION” section.
2. Pour a small amount of ISO VG 32 (10W SAE) oil in motor
inlet port.
3. Operate motor (unloaded) for 10 seconds in both directions to
flush out any impurities.
4. The motor is now ready for normal use.
