9. USE 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 overheating. Table A shows  
the correct size to use depending on  
cord length and nameplate ampere

improper accessories may cause risk of  
injury to persons.  
18. NEVER STAND ON TOOL. Serious  
injury could occur if the tool is tipped  
or if the cutting tool is unintentionally  
contacted.  
19. CHECK DAMAGED PARTS. Before  
further use of the tool, a guard or other  
part that is damaged should be carefully  
checked to determine that it will operate  
properly and perform its intended  
10. WEAR PROPER APPAREL. Do not wear

parts, binding of moving parts, breakage  
of parts, mounting, and any other  
conditions that may affect its operation.  
A guard or other part that is damaged  
should be properly repaired or replaced.  
11. ALWAYS USE SAFETY GLASSES. Also  
use face or dust mask if cutting operation  
is dusty. Everyday eyeglasses only have  
impact resistant lenses, they are NOT  
safety glasses.  
20. DIRECTION OF FEED. Feed work into  
a blade or cutter against the direction of  
rotation of the blade or cutter only.  
21. NEVER LEAVE TOOL RUNNING  
UNATTENDED. TURN POWER OFF.  
Don’t leave tool until it comes to a  
complete stop.  
12. SECURE WORK. Use clamps or a vise  
to hold work when practical. It’s safer  
than using your hand and it frees both  
hands to operate tool.

1. 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.

Plug and Outlet. The tool has a  
grounding plug that looks like the plug  
illustrated above in 125 V~ 3-Prong

8. The outlet must be properly installed and  
grounded in accordance with all codes  
and ordinances.  
2. Do not modify the plug provided – if it will  
not fit the outlet, have the proper outlet  
installed by a qualified electrician.  
9. Do not use an adapter to connect this  
tool to a different outlet.  
3. 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.

slightly loosen the (inner) Hex Nut, and  
retighten the (outer) Hex Nut.  
3. Insert a screwdriver in the lower-front  
notch of the Spring Cap (29).

remove the (outer) Hex Nut (30) only.
