(c) Operations:
1. Spindle brake: brake lever (E)
When arrow marks in (D) position,
spindle motor power is on. When arrow
marks in (C) position, spindle motor
power off through the engagement of
micro switch. When arrow marks in (B)
position, make spindle brake.
The lever is cam operated and will never
return back until you push it. The spindle
will be powered again as you push it to
position (D). All are controlled electric-
magnetically. This provides you a great
convenience for immediate stop of
spindle and shifting back gears.
ADJUSTMENT (Fig.3) (A)
After long period usage, the brake shoe
might be loosed and some adjustment is
required. Use a flat head driver to adjust
the bolt inside the hole at left-front
position of pulley cage. Clockwise will
tight the brake. Counter-clockwise will
loosen it.
2. Chucking of tooling shank and dismantling:
First the spindle must be raised up to its
maximum height. The screw of draw bar
is right turn. When the screw is turned
clockwise, it is for locking of tooling
shank; the draw bar must be turned
from three to five rounds. Then, use a
soft mallet to hit lightly on the draw bar
to allow the tooling shank to separate
from the spindle. Turn the draw bar until
the tooling shank comes off totally.
Note: According to Spindle Braking,
brake the spindle to a stop and the
tooling shank may easily come off or
chuck on.
