5.6 Lubrication
The Mill-Drill must be checked for proper lubrication
before operating. See sect.9.3.
6.0 Electrical connections
Electrical connections must be
made by a qualified electrician in compliance
with all relevant codes. This machine must be
properly grounded to help prevent electrical
shock and possible fatal injury.
The Mill-Drill will operate on single phase, 115 or
230-volt incoming power. It is prewired for 115-volt.
This machine uses an inverter to provide infinitely
variable spindle speeds within the specified ranges.
The inverter controls the speed of the motor by
varying the frequency of the voltage supplied to the
motor.
The Mill-Drill is not provided with a power plug; it is
recommended that the machine be “hardwired”
directly to a service panel (make sure a disconnect
is available to the operator). The user also has the
option of attaching an appropriate electrical plug.
Before connecting to power source, be sure switch
is in off position.
It is recommended that the Mill-Drill be connected to
a dedicated 15 amp circuit with circuit breaker or
fuse. NOTE: Local codes take precedence over
recommendations.
6.1 GROUNDING INSTRUCTIONS
This machine must be grounded. In the event of a
malfunction or breakdown, grounding provides a
path of least resistance for electric current to reduce
the risk of electric shock. This tool is equipped with
an electric cord having an equipment-grounding
conductor. If a plug is installed, it must be plugged
into a matching outlet that is properly installed and
grounded in accordance with all local codes and
ordinances.
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. The
conductor with insulation having an outer surface
that is green with or without yellow stripes is the
equipment-grounding conductor. If repair or
replacement of the electric cord or plug is
necessary, do not connect the equipment-grounding
conductor to a live terminal.
Check with a qualified
electrician or service personnel if the grounding
instructions are not completely understood, or if
in doubt as to whether the tool is properly
grounded. Failure to comply may cause serious
or fatal injury.
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept
the tool's plug.
Repair or replace damaged or worn cord
immediately.
If hardwired:
Permanently connected tools: This tool should be
connected to a grounded metal permanent wiring
system; or to a system having an equipment-
grounding conductor.
If used with a plug:
Grounded, cord-connected tools intended for use on
a supply circuit having a nominal rating less than
150 volts:
This tool may be used on a circuit that has an outlet
that looks like the one illustrated in A, Figure 6-1.
The tool is to be used with a grounding plug that
looks like the plug illustrated in A. Make sure the tool
is connected to an outlet having the same
configuration as the plug. An adapter, shown in B
and C, may be used to connect the plug to a 2-pole
receptacle as shown in B if a properly grounded
outlet is not available. The temporary adapter
should be used only until a properly grounded outlet
can be installed by a qualified electrician. The
green-colored rigid ear, lug, and the like, extending
from the adapter must be connected to a permanent
ground such as a properly grounded outlet box.
Note: In Canada, the use of a temporary adaptor is
not permitted by the Canadian Electrical Code,
C22.1.

Grounded, cord-connected tools intended for use on
a supply circuit having a nominal rating between 150
- 250 volts, inclusive:
This tool may be used on a circuit that has an outlet
that looks like the one illustrated in D, Figure 6-1.
The tool is to be used with a grounding plug that
looks like the plug illustrated in D. Make sure the tool
is connected to an outlet having the same
configuration as the plug. No adapter is available or
should be used with this tool.
