cord clamps as shown in the illustration.
Note:
• Make sure that the harnesses do not come into
contact with P.C. board components or with the
main P.C. board heat sink or the sub-P.C. board
heat sink.
• Use the cord clamps at the top of the control box
to adjust the harnesses so that they are not
loose inside the control box, particularly when
using the work table with the machine head
positioned vertically.

* Check that the harnesses do not touch the belt.

CAUTION
Be sure to connect the ground. If the ground connection is not secure, you run a high risk of receiving a
serious electric shock, and problems with correct operation may also occur.
1. Attach an appropriate plug to the power cord (1).
(The green and yellow wire is the ground wire.)
2. Insert the plug into properly-grounded AC power
supply.
Note:
• Do not use extension cord, otherwise machine
operation problems may result.
• Do not connect a power supply which is not of the
rated voltage, otherwise machine operation
problems may result.
