ご注意 

・スパナをパイプなどで延長して締め付けたりは絶対にしないでください。 
 
・締め付けナットだけにスパナを掛けて締め付けますと、ギヤなどに負担が掛
 かりますので、絶対にしないでください。必ず2本のスパナで作業してくだ
 さい。また、刃具溝部はチャッキングしないでください。 
 

Insert a tap into a collet and lightly tighten the nut by hand.

Tighten two set screws on the square portion of a tap shank equally and lightly.

Hook and tighten enclosed spanners on both of flats for spanner hooking and the nut. 

 Do not tighten a spanner extended with a pipe, etc..

 
 Do not tighten the nut individually because gears, etc. receive overload.  Always work 
 with two spanners.  Avoid chucking on the flute of a cutting tool.

クーラントは、位置決めブロックからアングルヘッド内部を通り、給

  油吐出口から吐出することが可能です。  

Coolant passes the inside of ANGLE HEAD from the stop block and comes out 
from  the exit hole of coolant supply. 

Synchronize both of cutting feed and reverse feed with a pitch of a tap (feed =  spindle speed × pitch)

The distance between the tip of a tap and a workpiece must be more than 13mm.

・クーラントはアングルヘッド内部の細い管内を通りますので、機械
 のクーラントタンクのメッシュはできるだけ細かいタイプをご使用
 ください。切粉が詰まってクーラントが出なくなる恐れがあります。 

Since the coolant passes through thin pipes inside ANGLE HEAD, use as fine 
filter in a  coolant tank as possible.  If chips are stuck in the pipes, coolant may 
not come out.
