. CONNECTION OF AIR LINE KIT
①
Connect the Filter Joint at the end of the Air Intake Hose of the air motor to the easy connection joint.
②
Fill oil reservoir through the Oil Filler Cap with recommended NAKANISHI oil (liquid parafn ISO VG
15)
to upper limit on the Reservoir. Disconnect from air supply prior to opening Oil Filler Cap. Do not over or
under ll.
③
Put the hose for air piping to the connector for air hose.
④
Attach the reversed side of the hose for air piping to the air compressor.
⑤
Supply air from the air compressor and turn regulator knob clockwise (clockwise = high) to set air pressure
between
0.3 - 0.5MPa.
⑥
Run the motor at the proper pressure. Close the Oil Drip Rate Adjusting Screw by turning
counterclockwise and then turn Oil Drip Rate Adjusting Screw clockwise to adjust drip rate to
30 - 40
drops/min. (If you're not using an NAKANISHI lubricator, adjust between
1 - 3 drops / min.)
CAUTION
NAKANISHI's lubricators deliver approximately 3% of the visible drip rate into the air line, but air ow
and oil viscosity could affect this rate. Please adjust the oil drip rate so that a full oil bowl depletes
from the upper gauge to the downer gauge (Approximately 40cc ) in 40 - 50 hours.
CAUTION
①
These motors require a clean, dry air supply to the air line kit for proper operation. Please connect
an air lter and / or dryer between the compressor and NAKANISHI's air line kit to ensure a clean,
dry air supply. Mount the air line kit as close as possible to the spindle to ensure a constant oil
supply. In high humidity areas please use a large capacity lter and / or dryer to ensure years of
trouble free operation.
②
Check that all hose connections are secure and strong to avoid accidental disconnection during
operation. Do not exceed 1.0MPa for incoming air pressure to the air line kit. In coming air pressure
from the compressor in excess of 1.0MPa may cause the air hose to burst.
③
About connection, operation and cautions of air line kit, refer to " air line kit Operation Manual ".
