6 First operation
6.1 Putting into use
The MA3 series motors are a ve cylinder radial piston type. This radial design, with it’s overlap of
power impulses, provides even torque at all speeds and full power in either direction of rotation. At least
two pistons are always on a power stroke.
These motors are designed for continuous service on 60-100 PSI air pressure. If overloaded beyond
their power capacity, the motor will simply stall without causing any damage.
ÚMake sure the air line is clean and free of scale and dirt before connecting to the motor.
ÚMake sure all pipe fittings are securely tightened to prevent air leaks.
ÚMake sure the air supply is securely attached and the compressor is turned on.
ÚMake sure the output spindle is properly engaged with the application.
ÚMake sure all necessary guards are in place to protect operator from rotating mechanisms.
Continuous Operation: Do not operate the MA3 motors faster than 65% of free speed. Install a filter/lubricator unit in the air line as close as possible to the MA2 motor.
Cleco
®
First Operation
Intermittent Operation: The splash lubrication from the motor case will be adequate.
If an excessive amount of water is found in the air line, a water trap should be installed to trap as
much as possible before it reaches the MA3 motor.

Danger of injury from accidental start up.
Turn off the compressed air before performing any maintenance.
---------------------------------------------------------------------------------------------------------------------------------------
8.1 Service schedule
Only qualied and trained personnel are permitted to perform maintenance on these motors.
Regular maintenance reduces operating faults, repair costs and downtime. In addition to the following
service schedule, implement a safetu related maintenance program that takes the local regulations for
repair and maintenance for all operating phases of the motor into account.

Maintenance
Page 16
8.2 Lubricants
For proper function and long service life, use of the correct lubricant is essential.
Oil identification
Fill the motor to the proper level before operating.
Use engine oil API Service Classified “SC” in the following weights:
Above 32° F: SAE 30W•
Below 32° F: SAE 10W•
If the air line carries an excessive amount of water and a water trap cannot be installed, use a good
grade of motor oil that will emulsify with water to prevent damage to vital parts of the motor.
Oil quantity
Approximately 1 quart of oil is required to fill the motor case to the proper oil level. Approximately
1 quart of oil is required to fill the gear case to the proper oil level. The oil must flow at all times to
properly lubricate the motor components, gears and bearings.
To check the MA3 for proper oil level, open the oil level pet cock. If oil does not flow from the pet
cock, add the proper oil until oil begins to flow. Securely tighten the oil level pet cock.
Remove the oil drain plug in the motor case occasionally and drain off accumulated water before
adding new oil.
Excessive use of oil is usually due to:

9.1 Motor case assembly
Install the pin (DP114) into the motor case until approximately 1/8” is exposed in the distributing valve
bushing hole.
Install the valve bushing (MA311) into the motor case counterbore until it is ush with the inside edge of
the counterbore. The valve bushing has a slot to enable proper alignment during assembly.
The valve bushing must be placed in a freezer, for a period of time, before assembling into the
motor case. This will cause the bushing to contract allowing easier assembly into the motor
case.
