2.  
Do not operate power tools in explosive atmospheres, such as in the pres-  
ence of flammable liquids, gases, or dust. Power tools create sparks which  
may ignite the dust or fumes.  
3.  
4.  
Keep bystanders, children, and visitors away while operating a power tool.  
Distractions can cause you to lose control. Protect others in the work area from  
debris such as chips and sparks. Provide barriers or shields as needed.  
ELECTRICAL SAFETY  
1.  
grounded tools must be plugged into an outlet properly installed and  
grounded in accordance with all codes and ordinances. Never remove the  
grounding prong or modify the plug in any way. Do not use any adapter  
plugs. Check with a qualified electrician if you are in doubt as to whether  
the outlet is properly grounded. If the tools should electrically malfunction or  
break down, grounding provides a low resistance path to carry electricity away  
from the user.  
2.  
3.  
Double insulated tools are equipped with a polarized plug (one blade is  
wider than the other). This plug will fit in a polarized outlet only one way.  
If the plug does not fit fully in the outlet, reverse the plug. If it still does  
not fit, contact a qualified electrician to install a polarized outlet. Do not  
change the plug in any way. Double insulation eliminates the need for the  
three wire grounded power cord and grounded power supply system.  
Avoid body contact with grounded surfaces such as pipes, radiators, rang-  
es, and refrigerators. There is an increased risk of electric shock if your body is  
grounded.  
4.  
5.  
Do not expose power tools to rain or wet conditions. Water entering a power  
tool will increase the risk of electric shock.  
Do not abuse the Power Cord. Never use the Power Cord to carry the tools  
or pull the Plug from an outlet. Keep the Power Cord away from heat, oil,  
sharp edges, or moving parts. Replace damaged Power Cords immediate-  
ly. Damaged Power Cords increase the risk of electric shock.  
6.  
1.  
When operating a power tool outside, use an outdoor extension cord  
marked “W-A” or “W”. These extension cords are rated for outdoor use, and  
reduce the risk of electric shock.  
PERSONAL SAFETY  
Stay alert. Watch what you are doing, and use common sense when oper-  
ating a power tool. Do not use a power tool while tired or under the influ-  
ence of drugs, alcohol, or medication. A moment of inattention while operating  
power tools may result in serious personal injury.

5.  
6.  
Dress properly. Do not wear loose clothing or jewelry. Contain long  
hair. Keep your hair, clothing, and gloves away from moving parts. Loose  
clothes, jewelry, or long hair can be caught in moving parts.  
Avoid accidental starting. Be sure the Power Switch is off before plugging  
in. Carrying power tools with your finger on the Power Switch, or plugging in  
power tools with the Power Switch on, invites accidents.  
Remove adjusting keys or wrenches before turning the power tool on. A  
wrench or a key that is left attached to a rotating part of the power tool may result  
in personal injury.  
Do not overreach. Keep proper footing and balance at all times. Proper  
footing and balance enables better control of the power tool in unexpected situa-  
tions.  
Use safety equipment. Always wear eye protection. Dust mask, non-skid  
safety shoes, hard hat, or hearing protection must be used for appropriate condi-  
tions.  
TOOL USE AND CARE  
1.  
Use clamps (not included) or other practical ways to secure and support  
the workpiece to a stable platform. Holding the work by hand or against your  
body is unstable and may lead to loss of control.  
2.  
3.  
Do not force the tool. Use the correct tool for your application. The correct  
tool will do the job better and safer at the rate for which it is designed.  
Do not use the power tool if the Power Switch does not turn it on or off.  
Any tool that cannot be controlled with the Power Switch is dangerous and must  
be replaced.  
4.  
Disconnect the Power Cord Plug from the power source before making any  
adjustments, changing accessories, or storing the tool. Such preventive  
safety measures reduce the risk of starting the tool accidentally.  
5.  
6.  
Store idle tools out of reach of children and other untrained persons. Tools  
are dangerous in the hands of untrained users.  
Maintain tools with care. Keep cutting tools sharp and clean. Properly  
maintained tools with a sharp cutting edge are less likely to bind and are easier  
to control. Do not use a damaged tool. Tag damaged tools “Do not use” until  
repaired.  
ꢀ.  
Check for misalignment or binding of moving parts, breakage of parts, and  
any other condition that may affect the tool’s operation. If damaged, have  
the tool serviced before using. Many accidents are caused by poorly main-  
tained tools.

grounded Tools: Tools with Three Prong Plugs  
1.  
Tools marked with “Grounding Required” have a three wire cord and three prong  
grounding plug. The plug must be connected to a properly grounded outlet. If  
the tool should electrically malfunction or break down, grounding provides a low  
resistance path to carry electricity away from the user, reducing the risk of electric  
shock. (See 3-Prong Plug and Outlet.)  
2.  
3.  
The grounding prong in the plug is connected through the green wire inside the  
cord to the grounding system in the tool. The green wire in the cord must be the  
only wire connected to the tool’s grounding system and must never be attached  
to an electrically “live” terminal. (See 3-Prong Plug and Outlet.)  
The tool must be plugged into an appropriate outlet, properly installed and  
grounded in accordance with all codes and ordinances. The plug and outlet  
should look like those in the following illustration.  
(See 3-Prong Plug and Outlet.)  
3-Prong Plug and Outlet  
Outlets for 2-Prong Plug  
Double Insulated Tools: Tools with Two Prong Plugs  
1.  
2.  
Tools marked “Double Insulated” do not require grounding. They have a special  
double insulation system which satisfies OSHA requirements and complies with  
the applicable standards of Underwriters Laboratories, Inc., the Canadian Stan-  
dard Association, and the National Electrical Code.  
(See Outlets for 2-Prong Plug.)  
Double insulated tools may be used in either of the 120 volt outlets shown in the  
preceding illustration. (See Outlets for 2-Prong Plug.)  
Extension Cords  
1.  
2.  
Grounded tools require a three wire extension cord. Double Insulated tools can  
use either a two or three wire extension cord.  
As the distance from the supply outlet increases, you must use a heavier gauge  
extension cord. Using extension cords with inadequately sized wire causes a  
serious drop in voltage, resulting in loss of power and possible tool damage.  
(See Table A.)

3.  
The smaller the gauge number of the wire, the greater the capacity of the cord.  
For example, a 14 gauge cord can carry a higher current than a 16 gauge cord.  
(See Table A.)  
4.  
5.  
When using more than one extension cord to make up the total length, make  
sure each cord contains at least the minimum wire size required. (See Table A.)  
If you are using one extension cord for more than one tool, add the nameplate  
amperes and use the sum to determine the required minimum cord size.  
(See Table A.)  
6.  
ꢀ.  
If you are using an extension cord outdoors, make sure it is marked with the suf-  
fix “W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.  
Make sure the extension cord is properly wired and in good electrical condition.  
Always replace a damaged extension cord or have it repaired by a qualified elec-  
trician before using it.  
8.  
Protect the extension cords from sharp objects, excessive heat, and damp or wet  
areas.

OPERATION  
1.  
Make sure the Power Cord of the Miter Saw is unplugged from its electri-  
cal outlet. Then, if necessary, make adjustments to the workpiece Holder (149),  
Baffle Plate (151), cutting depth, and miter angle and/or bevel angle.  
2.  
3.  
Raise the Motor Housing (26) to its full “UP” position.  
Check to make sure the Safety Button (16) and the Switch Lever (25) are operat-  
ing properly.  
4.  
5.  
6.  
ꢀ.  
Place the workpiece on the Turn Base (125) and against the Guide Fence (105).  
Use the Clamp Assembly (95 to 102) to hold the workpiece in place.  
Plug the Power Cord into the nearest 120 volt, grounded, electrical outlet.  
Depress the Safety Button (16) with your thumb, and squeeze the Switch Lever  
(25) on the Handle Cover (40). Then, release the Safety Button.  
8.  
When the Saw Blade (51) is turning at full speed, slowly bring down the Motor  
Housing (26) to complete the cut. NOTE: Feed the Saw Blade into the work-  
piece gradually. Do not force the machine to remove material faster than it was  
designed to cut.  
9.  
When cutting a large workpiece, make sure its entire length is properly support-  
ed. If necessary, use a roller stand (not included) with a larger workpiece.  
10.

INSPECTION, MAINTENANCE, AND CLEANINg  
WARNING! Always make sure the Switch Lever (25) is in its “OFF” position, and  
unplug the Power Cord from its 120 volt electrical outlet before performing  
any inspection, adjustments, maintenance, or cleaning.  
1.  
Before each use, inspect the general condition of the Miter Saw. Check for loose  
screws, misalignment or binding of moving parts, cracked or broken parts,  
damaged electrical wiring, loose, cracked, or bent Saw Blade (51), and any other  
condition that may affect its safe operation. If abnormal noise or vibration occurs,  
have the problem corrected before further use.  
Do not use damaged equipment.  
2.  
Daily: With a soft brush, cloth, or vacuum, remove all sawdust and debris from  
the Miter Saw. Then, use a premium quality, lightweight machine oil to lubricate  
all moving parts.  
3.  
4.  
When necessary: When the Dust Collection Bag (154) is half full, remove it  
from the Miter Saw, empty, and re-attach it to the Miter Saw.  
To replace the Motor Carbon Brushes: It may become necessary at sometime  
to replace the two Carbon Brushes (22) when the Motor performance decreases,  
or stops working completely. The Carbon Brushes are located on each side of  
the Motor Housing (26). To do so, use a standard screwdriver (not included) to  
remove the two Carbon Brush Caps (21). Then, remove the two Carbon Brushes  
from the Brush Holders (23). If the Carbon Brushes are worn down more than  
1/2, replace both Carbon Brushes. If, however, the Carbon Brushes are just dirty  
they may be cleaned by rubbing them with a pencil eraser. When installing the  
Carbon Brushes, make sure the carbon portion of the Carbon Brushes contact  
the Motor Armature, and that the springs face away from the Motor. Also, make  
sure the springs operate freely. After cleaning or replacement, replace the Car-  
bon Brush Caps with a screwdriver and tighten firmly.
