The green wire must be the only wire connected
to the machine’s grounding system and must
never be attached to an electrically “live”
terminal.
A temporary adapter, shown in Figure 6, can be
used to connect a grounded plug to a two-prong
outlet. The green rigid ear or lug extending from
the adapter must be connected to a permanent
ground such as a properly grounded outlet box
or receptacle. Simply remove the center screw
from the outlet, insert the adapter and re-attach
the screw through the grounding ear to the
outlet. If in doubt of proper grounding, call a
qualified electrician. A temporary adapter should
only be used until a properly grounded outlet
can be installed by a qualified electrician. The
Canadian Electrical Code prohibits use of
temporary adapters.
Extension Cords
Grounded tools require a three-wire extension
cord. As the distance from the supply outlet
increases, a heavier gauge extension cord must
be used. Using extension cords with
inadequately sized wire causes a serious drop in
voltage, resulting in loss of power and possible
tool damage.
Figure 7 shows recommended gauges. The
smaller the gauge number of the wire, the
greater capacity of the cord (for example, a 12-
gauge cord can carry a higher current than a 14-
gauge cord). If one extension cord is used for
more than one tool, add their nameplate
amperes and use the sum to determine the
required minimum wire size.
If you are using an extension cord outdoors, be
sure it is marked with the suffix “W-A” (“W” in
Canada) to indicate that it is acceptable for
outdoor use.
Be sure your extension cord is properly wired
and in good condition. Always replace a
damaged cord or have it repaired by a qualified
person before using it. Protect extension cords
from sharp objects, excessive heat, and damp
or wet areas.
Operation
Crosscut rulers: The panel saw comes with one
rip (vertical) ruler and two crosscut (horizontal)
rulers. The rip ruler is preset at the factory. The
crosscut rulers should be checked and, if
necessary, adjusted before operating the saw.
Also, they should be adjusted after every blade
change. See “Adjusting Crosscut Rulers” on
page 15.
