(Note 1)
When the machine is incorporated to some apparatus, do not open or close the primary side of
the controller but use external control input terminal in turning on and off.
(Note 2)
Power connecting work must be performed by personnel in charge of electric engineering.
When modifying or changing connection, see the operation manual of controller.
(Note 3)
When a chute that matches with the shape of specified parts is installed, and indication mark is
found around the controller speed adjusting knob, set the adjusting knob at corresponding
position in use.
(Note 4)
When you extend the load wire of the machine, use a wire of size above 2.5 mm
2
below 10 m.
Also conduct the protective continuity test and make sure that the wire is grounded
appropriately.
(Note 5)
See the operation manual of controller in use.
8. Inspection
and
Adjustment
(1)
Adjustment of counterweight
If irregular parts transportation speeds should occur between the front and rear areas on the feed and
alignment side chute, move the counterweight in the forward or backward direction to adjust the speeds.
(Note)
Tighten the counterweight fixing screw
securely. Also make sure that the fixing position
of the counterweight is within the moving range
shown in item 5 (Dimension of *2).
(2)
Inspection and adjustment of leaf spring of the body
[1] Acceptable maximum amplitude of leaf spring
Operate the machine with the amplitude below that shown in the following table in order to prevent
breakage of leaf spring.
If the machine is used with greater amplitude, the leaf spring may be broken earlier. For measuring
amplitude, stick the attached amplitude mark as a figure shown below and totalize readings of upper
and lower amplitude marks of leaf springs of body/feed side and return side without fail.

(Note)
When NTN specifies a recommended speed, set the speed
adjusting knob of controller at a corresponding
recommended graduation.
CAUTION
If the counterweight should move beyond the specified movable range, the
setscrew may loosen, resulting in dislocation of the counterweight from the
mounting area, followed by falling.
