Be sure your extension cord is 
properly wired and in good condition. 
Always replace a damaged extension 
cord or have it repaired by a qualified 
person before using it. Protect your 
extension cords from sharp objects, 
excessive heat and damp or wet areas.
Use a separate electrical circuit for 
your tools. This circuit must not be less 
than a #12 wire with a 20 A time-lag 
fuse or a #14 wire with a 15 A time-lag 
fuse. 
NOTE: When using an extension 
cord on a circuit with a # 14 wire, the 
extension cord must not exceed 25 feet 
in length. Before connecting the tool to 
the power line, make sure the switch 
is in the OFF position and the electric 
current is rated the same as the current 
stamped on the motor nameplate, 
running at a lower voltage will damage 
the motor.
In all cases make certain the 
receptacle in question is properly 
grounded. If you are not sure, have 
a certified electrician check the 
receptacle.
3.  If the tool suddenly stalls while 
cutting wood, release the trigger 
switch, unplug the tool, and free the 
blade from the wood. The saw may 
now be started and the cut finished.
4. 
FUSES may “blow” or circuit 
breakers may trip frequently if:
     a.  
MOTOR is overloaded –  
          overloading can occur if you feed 
          too rapidly or make too many 
          start/stops in a short time.
     b.  
LINE VOLTAGE is more than 
          10% above or below the 
          nameplate voltage rating. For 
          heavy loads, the voltage at 
          motor terminals must equal the 
          voltage specified on the nameplate.
     c.  
IMPROPER or dull saw blades 
          are used.
5.  Most motor troubles may be traced 
to loose or incorrect connections, 
overload, low voltage or inadequate 
power supply wiring. Always check 
the connections, the load and 
supply circuit if the motor doesn’t 
run well. Check minimum gauge for 
the length of cord you are using on 
the chart below.
GUIDELINES FOR EXTENSION 
CORDS
Use a proper extension cord. Make 
sure your extension cord is in good 
condition. When using an extension 
cord, be sure to use one 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 cause overheating. The 
table below shows the correct 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.
