CAUTION:
To prevent personal injury, or extensive machine damage, all electrical services
must be performed by an authorized Harig

distributor.
Violation will void the warranty.
9.1
Ground the machine by connecting the green wire to a satisfactory ground.
Neither the
building structure nor a hot water pipe is a satisfactory ground.
If a satisfactory ground is not available, drive an 8-foot copper ground rod into the ground and
securely clamp the ground wire to it.
9.2
Compare the rating label on the back of the spindle motor with your house current to make
certain they correspond.
9.3
Turn the main power disconnect handle to the “OFF” position and loosen the ¼ turn screws.
Open the control compartment.
CAUTION:
Make sure the machine disconnect is turned OFF before plugging or unplugging
any connectors to electronic logic units. Failure to observe this precaution may result in
permanent damage to the unit.
9.4
Bring the main line through the knockout on the back of the cabinet. Connect to the top of
the fused disconnect block.
9.5
Remove the wheel from the spindle.
9.6
Stand in front of the machine and turn the spindle motor ON. It should ROTATE
CLOCKWISE. If not, switch any two line wires to fused disconnect block.
(DO NOT switch
motor leads, as this will damage hydraulic system by making it run backward.)
