1. CAUTIONS FOR HANDLING AND OPERATION
■Read these warnings and cautions carefully and only use in the manner intended.
■These warnings and cautions are intended to avoid potential hazards that could result in personal injury to the
operator or damage to the device. These are classified as follows in accordance with the seriousness of the risk.
Class Degree of Risk
WARNING A safety hazard could result in bodily injury or damage to the device if
the safety instructions are not properly followed.
CAUTION A hazard that could result in light or moderate bodily injury or damage to
the device if the safety instructions are not followed.
WARNING
①Handling
Connection to the Air Line Kit should be performed by a person with experience with
compressed air and air compressors.
②Air Pressure
Compressed air is required. Do not exceed an air pressure of 1.0MPa at primary side and
0.85MPa at secondary side of the Air Line Kit.
③Use of Clean Air
Do not use compressed air contaminated with chemicals, oil compounds, organic solvents,
salinity, or corrosive gasses to avoid damage to the device.
④Connection of Hose
Connect the input hose securely to avoid accidental disconnection during use. Input pressure
should never exceed 1.0MPa.
Pressure exceeding 1.0MPa may cause the hose to rupture.
⑤Inlet and Outlet Parts
Do not hit, impact or cause shock to the Inlet or Outlet Connector Parts. Never put undo stress
or load on the Inlet or Outlet Connector Parts. Any damage to these components can cause air
leakage and the inability of the outlet quick disconnect to adequately secure the tubing.
⑥Dropping the Air Line Kit
When installing the Air Line Kit, securely install it on a flat, level surface. If the Air Line Kit is
dropped, damage to the Air Line Kit and injury to the operator is possible.
⑦Air Regulator Bowl
・The bowl is made of a polycarbonate.
Do not use the Air Line Kit in conditions where chemicals or organic solvents are present in
the atmosphere.
・Do not remove the bowl guard. Using the Air Line Kit without the bowl guard may cause
injury to the operator should the bowl burst.
・When removing the bowl from the regulator, remove all pressure from the Input and Outlet
sides of the Air Line Kit.
Thank you for purchasing the "AL - C1204" Air Line Kit for brushless motors and motor / spindles. This Air Line Kit
will supply clean and dry cooling air to the motor and spindle. THIS AIR LINE KIT IS NOT A SUBSTITUTE FOR
AN AIR DRYER. A Compressor is required to serve this Air Line Kit. Read this, the CONTROLLER and the Motor /
Spindle Operation Manuals carefully before using. Always keep this Operation Manual in a place where a user can
referred to for reference at any time.

10
CAUTION
①Use of dry air
Using compressed air containing excessive moisture could result in malfunction or failure
of the motor and spindle. If excessive moisture or condensation is found in Air Filter Bowl, it
will be necisary to install a larger Air Filter or dryer on the primary side of the Air Line Kit to
prevent and remove excessive moisture.
②Draining
Be sure to drain moisture and condensation from Air Filter Bowl regularly to avoid moisture
being carried to Motor and Spindle.
③Installation Location
Place this Air Line Kit on a flat and level surface.
If mounting on a wall, check if the wall is flat, and securely mount the Air Line Kit in a
horizontal direction.
④Handling
When removing the bowl for cleaning, carefully remove the bowl and do not damage to the
bowl.
CAUTIONS FOR STORAGE, INSTALLATION and OPERATION
①Do not use the Air Line Kit where corrosive gasses, chemicals, seawater, water, oils or steam
exist.
②Do not place in direct sunlight.
③Do not use where the Air Line Kit is subject to vibration or repetitive shock.
④Do not use where a heat source or radiated heat exist.
⑤To conform to "STORAGE, INSTALLATION and OPERATION" (Refer to " 3. SPECIFICATIONS ".)
①This Air Line Kit is designed to supply clean and dry cooling and purging air to CONTROLLER and Motor /
Spindle.
②The Air Filter traps small amounts of water and impure substances from the input air supply. This Air Line Kit is
not intended to be used or replace an Air Dryer.
③Air Pressure Regulator supplies steady airflow at a regulated air pressure.
④The Air Line Kit can be wall mounted.
