Electrical Safety
Electrical Safety- A Electrical Cord and Plug is not provided with Ordered Machine. Make sure to follow
Electrical Installation stated in the instructions below.
Power Supply
A separate electrical circuit should be used for each machine. This circuit should not be less than the wiring listed
below and should be protected with an appropriate circuit breaker based on the total running and start-up
amperage's (listed below). If an extension cord is used, use only 3-wire extension cords which have 3-prong
grounding type plugs and matching receptacle which will accept the machine’s plug.
If this information is different than what is stated on the Motor Specification Plate - omit this information. It is
possible that the documentation is outdated to a machine change - such as a different motor. Always check the
motor plate prior to any wiring. If any doubts, please consult a certified electrician. Know when to use a time delay
fuse! AKA Slow blow fuse. Generally, if the motor uses a start capacitor, a time delay fuse is required. This type of
fuse (circuit breaker) will not trip with the initial amperage needed to start the machine, which is typically double
that of the running amperage. Most woodworking machines use this type of fuse.
Electrical Safety- Electrical Cord and Plug is not provided with Ordered Machine. Make sure to have a
Qualified Electrician install required a qualified/standardized electrical cord and plug for purchased
machine. *Electrical Code that must be met in your local state (USA) or province (CSA). An electrician
will verify that all the demands are met to properly wire the machine. If you have absolutely any doubt
when wiring this machine - please consult with a Qualified Electrician.

Grounding Methods
Grounding Methods- Electrical Cord and Plug is not provided with Ordered Machine.
When a proper qualified electrical cord and plug is installed please follow the following ground methods
and procedures.
Grounding Methods Provided by CSA Group.
Fig. (A) Receptacle with nominal rating less than 150 volts.
Fig. (B) 150 Volt receptacle without grounding pin fitted with adapter.
Fig. (C) 150-250 Volt receptacle.
1.) All Grounded, Cord-Connected Machines:
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 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 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. 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.
2.) Grounded, cord-connected machines intended for use on a supply circuit having a nominal rating less
than 150 volts:
This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in
Fig. A.) The tool has a grounding plug that looks like the plug illustrated in Fig A.) A temporary adapter, which
looks like the adapter illustrated in Fig B may be used to connect this plug to a 2 Pole receptacle as shown in Fig.
B.) if a properly grounded outlet is not available. The temporary adapter should be used only until a properly

PX-20 SHEARTEC II PLANER18
grounded outlet can be installed by a qualified electrician. This adapter is not permitted in Canada. 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.
3.) Grounded, Cord-Connected tools intended for use on a supply circuit having a nominal rating
between 150 – 250 volts, inclusive:
This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in
Fig. C. The tool has a grounding plug that looks like the plug illustrated in Fig. C. 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. If the tool must be reconnected for use on a different type of electric circuit, the reconnection should
be made by qualified service personnel; and after reconnection, the tool should comply with all local codes and
ordinances.
EXTENSION CORDS ARE NOT RECOMMENDED. If the customer needs to use an extension
cord, the Extension Cord must be qualified to fall within Local Electrical Code (USA, CSA, etc.). If the
customer utilizes an Extension Cord that does not fall within Code and causes damage to machine, the
Warranty will be Voided.
