Electric Models: 

The applicable national and local electrical 
codes and enforcement bodies will be the 
determining authority on the proper 
connections and use of this machine.  In all 
cases it the operator/owner’s responsibility to 
ensure that this equipment is in full 
compliance with these codes. 

All machine adjustments & maintenance shall 
only be done after the machine’s power switch 
has been put in the “OFF” position & the 
power supply cord completely disconnected. 

Make sure that the extension cord length is 
properly sized for the motor used on this saw. See 
the chart in Section 2 of this document. 

Single phase 1-1/2 hp motors are factory wired for 
115 volt service and furnished with the correct 
NEMA configuration Plug (LL) [See FIG. 1] on the 
motor pigtail.  See Table 1 below for the proper 
matching connectors:

For operator convenience, the 1-1/2 hp motor has 
a Voltage Change Switch (J) [See FIG. 5] that 
allows operation on a 115 VAC or a 230 VAC 
power source.  The voltage change switch (J) is 
mounted on the terminal box of the motor and must 
be set to either 115, or 230 Volt, to match the 
voltage supply. Make sure that the Voltage Change 
Lock Bolt (TT) is in position.  It will prevent the 
Voltage Change Switch [See FIG. 5] from being 
accidentally moved into the wrong position. 

WARNING: The Voltage Change Switch (J) 
position is never to be changed while the motor 
is running.  Make sure that the Voltage Change 
Lock Bolt (TT) is in position.  It will prevent the 
Voltage Change Switch from being accidentally 
moved into the wrong position. 

Local electrical codes may require changing the 
plug on the motor to the proper NEMA connector to 
match the voltage supply. 

The operator must use plug and receptacle 
connectors on all power cords (machine and 
extension), designed and approved for the selected 
motor voltage and equal to or greater than the 
rated motor full load current. 

The service receptacle, branch circuit conductors, 
and overcurrent protection shall have an ampere 
rating equal to or greater than the motor full load 
current.  According to the National Electrical Code 
if the branch circuit has two or more receptacles, 

each receptacle has a maximum load ampere 
rating equal to 80% of the receptacle’s rating.  
When this machine is set up to operate on 115 
VAC, the motor has a full load rating of 19 
amperes.  This means that when operating this 
machine on 115VAC, it can only be used on a 
branch circuit with ONE 20-ampere rated 
receptacle.  If the circuit has two or more 20-
ampere receptacles, they each have load rating of 
16 amperes and cannot be used by this machine.  

WARNING: Always make sure the unit in 
connected to a properly grounded electrical 
outlet.  Failure to comply with this warning 
could result in serious bodily injury or death! 

WARNING: DO NOT operate on low voltage!  
Low voltage causes loss of power, motor 
overheating, and possibly motor winding 
burnout.  Voltage should be checked at the 
motor while it is operating. 

The extension cord(s) used must have a voltage 
rating greater than the selected voltage (115 or 
230) and be sized for the rated motor full load 
amps (as marked on motor specification plate). 

Good motor performance depends on proper 
voltage.  Extension cords that are too long and / or 
too small reduce the voltage to a motor under load. 
Operating below this minimum voltage will cause 
an increase in motor current resulting in slow 
startup, and overheating in the motor and controls.  
Sustained operation under these conditions will 
result in permanent damage to the motor and 
controls. 

Long extension cords will probably have to be 
oversized to minimize the voltage drop to the 
machine.  The size of the extension cord is 
dependent on the total conductor length (all 
extension cords) & the quality of the power source.  
The power cord size shall be capable of supplying  
a minimum of 90% of the motor nameplate 
voltage at the motor, when the motor is running 
rated full load. 

Make sure that the extension cord length is 
properly sized for the motor used on this machine.  
Use extension cords NO SMALLER than the sizes 
indicated in Table 2 below:

The branch circuit must have overcurrent 
protection in the form of a circuit breaker or fuses.  
The purpose of the overcurrent protection is to limit 
the current in the branch circuit conductors and 
connections to an amount equal to or less than 
their ratings.  This is to prevent overheating that 
can lead to damage or a fire.  The overcurrent
