Porter-Cable 28-306 Saw User Manual


 
5
A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should be pro-
tected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3-prong ground-
ing type plugs and matching receptacle which will accept the machine’s plug. Before connecting the motor to the power line,
make sure the switch is in the “OFF” position and be sure that the electric current is of the same characteristics as indicated on
the machine. All line connections should make good contact. Running on low voltage will damage the motor.
DO NOT EXPOSE THE MACHINE TO RAIN OR OPERATE THE MACHINE IN DAMP LOCATIONS.

2. Grounded, cord-connected machines intended for
use on a supply circuit having a nominal rating less
than 150 volts:
If the machine is intended for use on a circuit that has an out-
let that looks like the one illustrated in Fig. A, the machine will
have a grounding plug that looks like the plug illustrated in Fig.
A. A temporary adapter, which looks like the adapter illustrat-
ed in Fig. B, may be used to connect this plug to a matching
2-conductor receptacle as shown in Fig. 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.
Whenever the adapter is used, it must be held in place with a
metal screw.
NOTE: In Canada, the use of a temporary adapter is not
permitted by the Canadian Electric Code.
IN ALL CASES, MAKE CERTAIN THAT THE
RECEPTACLE IN QUESTION IS PROPERLY
GROUNDED. IF YOU ARE NOT SURE, HAVE A
QUALIFIED ELECTRICIAN CHECK THE
RECEPTACLE.
1. All grounded, cord-connected machines:
In the event of a malfunction or breakdown, grounding pro-
vides a path of least resistance for electric current to reduce
the risk of electric shock. This machine is equipped with an
electric cord having an equipment-grounding conductor and a
grounding plug. The plug must be plugged into a matching
outlet that is properly installed and grounded in accordance
with all local codes and ordinances.
Do not modify the plug provided - if it will not fit the outlet, have
the proper outlet installed by a qualified electrician.
Improper connection of the equipment-grounding conductor
can result in risk of electric shock. The conductor with insu-
lation 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 neces-
sary, 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 machine is properly grounded.
Use only 3-wire extension cords that have 3-prong grounding
type plugs and matching 3-conductor receptacles that accept
the machine’s plug, as shown in Fig. A.
Repair or replace damaged or worn cord immediately.
POWER CONNECTIONS
MOTOR SPECIFICATIONS
Depending on the optional stand purchased, the tool is either wired for 120 volt, or 240 volt with 60 Hz. alternating current.
Before connecting the tool to the power source, make sure the switch is in the “OFF” position.
GROUNDING INSTRUCTIONS
THIS MACHINE MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM
ELECTRIC SHOCK.
