WORK AREA SAFETY
•Keep work area clean and well lit. Cluttered areas and benches invite accidents
• Avoid dangerous environments. Do not use your power tool in rain, damp or wet locations or in the presence of
explosive atmospheres (gaseous fumes, dust or fl ammable materials). Remove materials or debris that may be ignited
by sparks.
• Keep bystanders away.. Children and bystanders should be kept at a safe distance from the work area to avoid
distracting the operator and contacting the tool or extension cord.
• Protect others in the work area from debris such as chips and sparks. Provide barriers or shields as needed.
• Make workshop child proof with padlocks, master switches, or by removing starter keys
ELECTICAL SAFETY
• 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 adaptor plugs. Check
with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. If the tool should electrically
malfunction or break down, grounding provides a low resistance path to carry electricity away from the user.
• 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.
• Guard against electric shock. Prevent body contact with grounded surfaces such as pipes, radiators, ranges and
refrigerators. When making blind or plunge cuts, always check the work area for hidden wires or pipes. Hold your tool by
insulated nonmetal grasping surfaces. Use a Ground Fault Circuit Interrupter (GFCI) to reduce shock hazards.
• Do not expose to rain or use in damp locations.
• Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep cord away
form heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the
risk of electric shock
PERSONAL SAFETY
• Know your power tool. Read this manual carefully to learn your power tool’s applications and limitations as well as
potential hazards associated with this type of tool.
• Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use tool
while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power
tools may result in serious personal injury.
• Dress properly. Do not wear loose clothing or jewellery. Wear a protective hair covering to contain long hair. These
may be caught in moving parts. When working outdoors, wear rubber gloves and insulated non-skid footwear. Keep hands
and gloves away from moving parts.
• Reduce the risk of unintentional starting. Be sure your tool is turned off before plugging it in. Do not use a tool if the
power switch does not turn the tool on and off. Do not carry a plugged-in tool with your finger on the switch.
• Remove all adjusting keys and wrenches. Make a habit of checking that adjusting keys, wrenches, etc. are removed
from the tool before turning it on.
• Do not overreach. Maintain control. Keep proper footing and balance at all times. Maintain a firm grip. Use extra care
when using tool on ladders, roofs, scaffolds, etc.
• Use safety equipment. Everyone in the work area should wear safety goggles or glasses with side shields
complying with current safety standards. Everyday eyeglasses only have impact resistant lenses. They are not safety
glasses. Wear hearing protection during extended use and a dust mask for dusty operations. Hard hats, face shields,
safety shoes, etc. should be used when specif ed or necessary. Keep a fire extinguisher nearby.
• Keep guards in place and in working order.
• Never stand on tool. Serious injury could occur if the tool is tipped or if the cutting tool is unintentionally contacted.
• Keep hands away from all cutting edges and moving parts.

POWER TOOL USE AND CARE
• Secure work. Use a clamp, vise or other practical means to hold your work securely, freeing both hands to control
the tool.
• Do not force tool. Your tool will perform best at the rate for which it was designed. Excessive force only causes operator
fatigue, increased wear and reduced control.
• Use the right tool. Do not use a tool or attachment to do a job for which it is not recommended. For example, do not
use a circular saw to cut tree limbs or logs. Do not alter a tool.
• Unplug tool when it is not in use, before changing accessories or performing recommended maintenance.
• Store idle tools. When not in use, store your tool in a dry, secured place. Keep out of reach of children.

After making several cuts, the cutting speed of the wheel may be reduced due to glazing on the outer edge of the chop saw cut-off
wheel. This glazing is caused by a build-up of molten metal on the cutting surface of the wheel which prevents the abrasive surface
from contacting the metal being cut.
If the cutting action slows down, deglaze as follows:
1. Make sure the switch is in the OFF position and let the cut-off wheel cool down for at least 1-2 minutes.
2. Remove the workpiece from the vice and replace it with a scrap workpiece.
3. When the scrap workpiece is firmly fastened in the vice, turn the switch ON.
4. When the chop saw motor reaches full speed, SLOWLY lower the wheel onto the workpiece, only allowing it to make LIGHT
CONTACT with the workpiece. Repeat this action 4-5 times.
NOTE: The light contact with the workpiece will remove the cold glazing and the cut-off wheel will once again begin to cut more
aggressively.

WARNING! When servicing, use only original equipment replacement parts. The use of any other parts may create a safety hazard
or cause damage to the tool. Any attempt to repair or replace electrical parts on this saw may create a safety hazard unless repairs
are performed by a qualified technician. For more information, call the Toll-free Helpline, at 1-866-349-8665.
