7. Control and Repair of Product

7-1. Control of Column Clamp

If the strength of the column clamp is weak
(if the arm rotates even after the column is
clamped), please tighten the hexagonal nuts in
four clamp bolts gradually.
If the nuts are tightened too much, it is
impossible to carry out efficient work as the
rotation of the sleeve is heavy even after the
column clamp is loosened. Therefore, please
adjust properly.

7-2. Control of Arm Clamp

If the clamp strength of the arm is weak,
please adjust it by tightening the hexagonal
nuts in two outside clamp bolts among 4 clamp
bolts.
If the clamp strength of the arm is strong,
please be careful as it will be impossible to
clamp the arm because the overload safety
clutch directly connected to the motor shaft
inside the arm elevation feed box will be
operated.
During ascension of the arm, please adjust the
commercial current to 5~5.5A.

7-3. Control of Spindle Box Clamp

As the spindle box is clamped on the slideway
face of the arm by the clamp shaft, if the
clamp strength is weak, please adjust the
clamping amount by gear.
Please remove the bracket and cover if the
spindle box clamp is loose.
Please separate the clamp shaft from the gear,
assemble the gear to the clamp shaft again
after turning one or two teeth toward the
clamp direction, and assemble the cover and
bracket.
