ASSEMBLY PROCEDURE
ASSEMBLY PROCEDURE
ASSEMBLING THE INSTRUMENT BODY
1Take the instrument body (1) out of the container and put it on the table.
2Slightly raise the omni-directional joystick, and pull out the cushion from
the lower part of the base in the arrow direction.
3Wipe the sliding board with a cloth to remove any dirt.
WARNING To avoid electric shock, be sure to unplug the power cable
before assembling. Also, do not plug the power cable in
before assembling.
CAUTION To prevent the instrument from falling and to avoid injury,
do not install the instrument on an uneven or unsteady
surface, including a slope.
CAUTION
To avoid injury during carrying, be sure to hold the instru-
ment body at the bottom with two people. Carrying by
one person may cause backache or injury by falling.
Holding at areas other than the bottom may also cause
pinched fingers and injury, as well as falling, thereby caus-
ing damage to the instrument.
NOTE Since the upper part and lower part of the instrument
body are merely connected with the power cable, take
them out together so they do not separate from each
other.

ASSEMBLY PROCEDURE
CONFIRMATION AFTER ASSEMBLY
1Slide the base to the left, as viewed from the operator side, and make sure
that the voltage selector is set at 100V.
2Make sure that the input voltage is within the range ±10% of 100V.
If the input voltage exceeds the range, use a constant-voltage power supply
(marketed: 400VA or higher).
3Loosen the base brake knob, and move the omni-directional joystick to
confirm that it moves smoothly in the following directions:
1) Right-left movement
2) Back-forth movement
3) Up-down movement
Just after being unpacked, the right-left movement may be uneven. If so, move
the joystick with force to its limits in the right-left and up-down directions.
