Nakanishi AL-0203 User manual

Thank you for purchasing Air Line Kit（AL-0203）.
This device is designed for E800Z standard set. It provides Control Unit with clean air flow as
well as SPINDLE（NR-3080）with oil mist. Read the operation manual carefully before initial use.
WARNING
⁄Read these cautions carefully to correctly follow the intended use.
¤Safety instructions are intended to avoid potential hazards that could result in personal
injuries or damages to the device.
Safety instructions are classified as follows in accordance with the seriousness of the risk.
Class DegreeofRisk
WARNING Existence of a hazard that could result in bodily injury or damage of the device,
if the safety instructions are not followed.
CAUTION Possibility of a hazard that could result in light or middle degree of bodily injury
or damage of device, if the safety instructions are not followed.
⁄Use of dry air
Use of air with excessive moisture could result in malfunction or failure of air tools. In
case large moisture condensation is often found at the air filter of this air line kit, it is
recommended to install a larger air filter or air dryer before the primary side of the air
line kit.
¤Draining
Be sure to drain moisture condensation from Filter regularly to avoid moisture
carried by air to the air tool.
‹Installation Location
Place this device on a flat surface. When placing it on the wall, check if the wall is
flat. Hang it horizontally.
›Handling
Care should be exercised and avoid breaking Plastic Bowl of Filter when it is
removed for cleaning.
CAUTION
An experienced and well-informed person shall assemble, operate and service the
air compressor.
WARNING
⁄Air Pressure
Use the air pressure below 1.0MPa on primary side and 0.6MPa on secondary side.
¤Use of Clean Air
Air shall be clean and free from chemicals, compound oil containing organic solvent,
salinity, or corrosive gas to avoid damage to the device.
‹Connection of Hose
Connect hose securely to avoid accidental disconnection during use. Do not exceed
1.0MPa for air hose pressure. Make sure that the pressure from the air compressor
does not exceed 1.0MPa. If the pressure exceeds 1.0MPa, hose might burst.
CAUTIONSINHANDLING
1

FEATURES
Air Line Kit
AL-0203
OM-K0288E Rev.A

In NAKANISHI lubricator, oil content in air exiting lubricator is approximately 3% of
dripping oil. Adjust the oil drip rate so that oil, full in the bowl, depletes in 40-50 hours.
CAUTION
When the lubricant is filled above the maximum oil level, remove the excess amount.
Excess oil might result in poor or failure of oil supply. When supplying or removing
oil, stop the air supply to Air Line Kit.
・Removing oil and moisture
Remove oil in Reservoir once a month. Open Valve at the bottom of Reservoir by turning
counterclockwise. Moisture might be collected and mixed with oil in Reservoir and could
cause damage.（
See Fig. 5 ）
・Adjustment of oil drip rate
While running the air tool at the proper pressure, adjust the oil drip rate to the
recommended rate by turning Oil Drip Rate Adjusting Screw. The oil drip rate could be
checked through Sight Dome. Turn Oil Drip Rate Adjusting Screw clockwise to increase the
rate and counterclockwise to decrease. Adjust to 25-35 drips/min. for NAKANISHI Air Line
Kit Lubricator.（
See Fig. 6 ）
WARNING
5COMPONENT PARTS
⁄Air Filter
Moisture, dirt and debris are separated from the compressed air and
collected in Plastic Bowl. Drain by pushing Drain Valve sideways.
（See Fig. 2）
¤Air Pressure Regulator
Air Line Kit（AL-0203）incorporates two pressure regulators on its
secondary: one for air supply and the other to lubricator. Each
should be adjusted to the proper pressure reading. To increase the
air pressure, pull Regulator Knob outward and turn it in either
direction. Set at the recommended air pressure.（See Fig. 3）
‹Pressure Gauge
Check the air pressure with this gauge.（See Fig. 4）
›Lubricator
・Supply of Oil
Check the amount of oil in the bowl. Fill oil to the upper limit of oil level.
（ See Fig. 5 ）

Problem Action Taken
Air tool could not rotate regularly when inclining or
giving shakes to the lubricator.
Air tool could not rotate normally. Drain oil to proper
level by loosening Drain Valve.
Excess oil could slow bearings rotation. Decrease oil
drip rate.
Check the joint and re-tighten screws.
Replace hose.
Drain moisture.
Air leakage.
Broken hose.
No or poor oil supply.
Excess lubrication.
Drain moisture from Lubricator and replace oil.
Moisture in Lubricator.
Moisture in Air Filter.
Check Regulator and set at the correct air pressure.
Check every hose connection.
Check the power supply and the air outlet of the
air compressor.
Check if hose is broken, bent or disconnected.
No air flow.
Check oil volume in Lubricator and increase the oil drip
rate. When using NAKANISHI lubricator, adjust to 25-35
drips/min. and supply lubricant into Supply Air Hose
directly.
