3. Rotate the shaft by hand in both directions for a few min-
utes.
4. You must wear eye protection for this step. Cover
exhaust with a cloth and reconnect the air line.
5. Restart the motor at a low pressure of approximately 10
PSI/0.7 bar until there is no trace of solvent in the exhaust
air.
6. Listen for changes in the sound of the motor. If motor
sounds smooth, you are finished. If motor does not sound
like it is running smoothly, installing a service kit will be
required. See Service Kit information on page 6 and call
Customer Service to order.
Cleaning Muffler
1. Remove the muffler.
2. Clean the felt filter with soap and water.
3. You must wear eye protection for this step. Lubri-
cate motor with 3 - 4 drops of oil.
4. Check the air compressor.
5. Listen for changes in the sound of the motor. If motor sounds
smooth, you are finished. If motor does not sound like it
running smoothly, installing a service kit will be required.

5. Remove the muffler.
6. Wear eye protection. Keep away from air stream. Use
clean, dry air to remove condensation from the inlet port of
the motor.
7. Lubricate motor with a small amount of oil into the intake
port. Rotate shaft by hand several times to distribute oil.
8. Plug or cap each port.
9. Coat output shaft with oil or grease.

Based on running pressure of 60 PSI and coupling connection
to motor load. The direction, magnitiude and location of
applied loads to the motor shaft will change expected bearing
life. Driving the motor with wet dirty compressed air can
reduce expected bearing life. The above are life estimates not
warranted minimum values.
