Model H8178 (Mfg. Since 07/07)
NOTICE
Make sure to position the left and right
stops so that the table can travel an additional 10mm before the leadscrew runs out
of thread. The reason for this additional
table travel is that after using the rapid feed
feature, the momentum of the motor armature keeps rotating leadscrew so the table
moves a few millimeters past your normal
stop location. If the lead screw runs out of
travel before the table naturally slows to a
stop, a damaging hard stop will occur.
Periodically, make sure that you always
have the appropriate table free travel past
the stop setting to prevent damaging hard
stops.
24. Install the appropriate left and right feed stops
for your milling machine into the table slot, as
shown in Figure 17.
26. Install the limit switch mounting plate on the
side of the milling table base so the limit
switch stop pins are horizontally aligned with
the stop pins as shown in Figure 18.
Also make sure that when mounted, the limit
switch housing has enough of a gap (also
shown in Figure 18) between the gib screw
lock nut so it can be adjusted.
27. When the mounting plate is properly positioned, center punch one mounting hole.

Note: You may want to additionally drill and
insert a roll pin to prevent any chance of a
stop block inadvertently moving past the stop
setting. If the stop moves past your maximum
stop setting, the lead screw will run out of
thread and slam the table and power feed to
a hard stop causing possible damage.

28. Using your electric drill, drill one #25 mount-
ing hole 1/2" deep into the table base.
29. Using a #10-24 bottoming tap, cut threads
into the hole.
30. Secure the limit switch mounting plate to the
table base with one #10-24 x 1/2" flat head
screw.
31. Center punch the other hole and drill, tap,
and install the remaining screw.
32. Install the limit switch to the mounting plate
with the three previously removed screws.
33. Secure the power and limit switch power
cables away from the path of the moving
table and handwheels.

Wiring Safety Instructions
SHOCK HAZARD. Working on wiring that is con-
nected to a power source is extremely dangerous.
Touching electrified parts will result in personal
injury including but not limited to severe burns,
electrocution, or death. Disconnect the power
from the machine before servicing electrical components!
MODIFICATIONS. Modifying the wiring beyond
what is shown in the diagram may lead to unpredictable results, including serious injury or fire.
This includes the installation of unapproved aftermarket parts.
WIRE CONNECTIONS. All connections must
be tight to prevent wires from loosening during
machine operation. Double-check all wires disconnected or connected during any wiring task to
ensure tight connections.
CIRCUIT REQUIREMENTS. You MUST follow
the requirements at the beginning of this manual
when connecting your machine to a power source.
WIRE/COMPONENT DAMAGE. Damaged wires
or components increase the risk of serious personal injury, fire, or machine damage. If you notice
that any wires or components are damaged while
performing a wiring task, replace those wires or
components.
MOTOR WIRING. The motor wiring shown in
these diagrams is current at the time of printing
but may not match your machine. If you find this
to be the case, use the wiring diagram inside the
motor junction box.
CAPACITORS/INVERTERS. Some capacitors
and power inverters store an electrical charge for
up to 10 minutes after being disconnected from
the power source. To reduce the risk of being
shocked, wait at least this long before working on
capacitors.
EXPERIENCING DIFFICULTIES. If you are experiencing difficulties understanding the information
included in this section, contact our Technical
Support at (570) 546-9663.
