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 pe
r
sonnel 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.
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
,
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.

Extension cords
The use of extension cords is discouraged; try to
position equipment within reach of the power
source. If an extension cord becomes necessary,
be sure it is heavy enough to carry the current your
product will draw. An undersized cord will cause a
drop in line voltage resulting in loss of power and
overheating.
Table 2 shows recommended size to use
depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.

Table adjustment
To raise or lower table, loosen lock handle (A,
Figure 7-1) and rotate crank (B). Always tighten
lock handle before operations. Note: Lock handle
can be repositioned – pull out on handle, rotate,
and allow it to resettle on pin.
If drill press base will be used for securing
workpiece, loosen lock handle (A) and swing table
around column and out of the way, making sure
rack follows it without binding. If rack tries to bind,
bump rack gently with rubber mallet to free its
movement.
