WARNING
（1） The spindle is not a hand tool. It is designed to be installed and used in machine tools
or special purpose machines.
（2） Do not touch the cutting tool while it is running. It is very dangerous.
（3） Wear safety glasses and a dust mask, and use a protective cover around the spindle
whenever the spindle is rotating.
（4） Never connect, disconnect or touch the Power Cord Plug or Motor Cord Plug with wet
hands. This may cause an electric shock.
（5） Never operate or handle the spindle until you have thoroughly read the Operation
Manual and safe operation has been confirmed.
1） To prevent injury and damage, check the spindle and cutting tool for proper installation
before operating the spindle.
2） Before disconnecting the spindle, check the safety of the spindle and cutting tool,
turn OFF the control power, stop the supply of coolant and compressed air, and
release the residual coolant and compressed air from the system.
（6） When installing the spindle, make sure that the fixed base is grounded to the machine
tool in order to avoid the risk of an electric shock.
（7） When installing a drill, tighten the collet properly and check the collet and collet nut
again before use. Do not overtighten the collet. Doing so may cause damage to the
spindle.
（8） Do not use poor-quality drills (poor balance, large runout, scratches on the shank,
and so on). Such drills could break when used, resulting in injury to operators. When
using a new drill, start at a low speed and check to make sure it operates safety,
gradually increasing the rotation speed.
（9） Do not exceed the maximum recommended allowable drill speed. For your safety, use
speeds below the maximum allowable speed.
（10） Do not apply excessive force. This may cause drill slippage, drill damage, injury to the
operator or loss of concentricity and precision.
（11） When using coolant, check the operating pressure before connecting the coolant
hose and fittings. If the maximum operating pressure of the coolant hose or fittings is
exceeded, they could burst and cause injury.
（12） Connect the coolant hose and fittings securely. A coolant leak could cause injury or
damage the device.
（13） When using an oil-based coolant, the coolant may be dispersed as a fine mist that
could ignite. Implement fire prevention measures such as the use of dust collectors
and automatic fire extinguishers.
（14） If there is residual pressure in the high-pressure pump, the drill may pop out, resulting
in injury. Make sure that there is no residual pressure before replacing the drill.
