GENERAL SAFETY RULES
1. Keep work area clean and well lit. Cluttered, dark work areas
invite accidents.
2. Avoid dangerous environments. Do not use your power tool in
rain, damp or wet locations or in the presence of explosive atmo-
spheres (gaseous fumes, dust or flamma le materials). Remove
materials or de ris that may e ignited y sparks.
3. Keep bystanders away. Children and ystanders should e kept
at a safe distance from the work area to avoid distracting the opera-
tor and contacting the tool or extension cord.
4. Protect others in the work area from de ris such as chips and
sparks. Provide arriers or shields as needed.
5. Make workshop child proof with padlocks, master switches, or
y removing starter keys.
6. 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 dou t as to whether the outlet is properly
grounded. If the tool should electrically malfunction or reak down,
grounding provides a low resistance path to carry electricity away
from the user.
7. Double insulated tools are equipped with a polari ed plug
(one blade is wider than the other). This plug will fit in a
polari ed 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 polari ed outlet. Do not change
the plug in any way. Dou le insulation eliminates the need for
the three wire grounded power cord and grounded power supply
system.
8. Guard against electric shock. Prevent ody contact with
grounded surfaces such as pipes, radiators, ranges and refrigera-
tors. When making lind or plunge cuts, always check the work area
for hidden wires or pipes. Hold your tool y insulated nonmetal
grasping surfaces. Use a Ground Fault Circuit Interrupter (GFCI) to
reduce shock hazards.
9. Do not expose to rain or use in damp locations.
10. 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.
11. Know your power tool. Read this manual carefully to learn your
power tools applications and limitations as well as potential haz-
ards associated with this type of tool.
12. 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 mo-
ment of inattention while operating power tools may result in serious
personal injury.
13. Dress properly. Do not wear loose clothing or jewelry. Wear a
protective hair covering to contain long hair. These may e caught in
moving parts. When working outdoors, wear ru er gloves and
insulated non-skid footwear. Keep hands and gloves away from
moving parts.
14. Reduce the risk of unintentional starting. Be sure your tool is
turned off efore 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.
15. Remove all adjusting keys and wrenches. Make a ha it of
checking that adjusting keys, wrenches, etc. are removed from the
tool efore turning it on.
16. Do not overreach. Maintain control. Keep proper footing and
alance at all times. Maintain a firm grip. Use extra care when using
tool on ladders, roofs, scaffolds, etc.
17. 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 protec-
tion during extended use and a dust mask for dusty operations. Hard
hats, face shields, safety shoes, etc. should e used when speci-
fied or necessary. Keep a fire extinguisher near y.
18. Keep guards in place and in working order.
19. Never stand on tool. Serious injury could occur if the tool is tipped
or if the cutting tool is unintentionally contacted.
20. Keep hands away from all cutting edges and moving parts.
21. Secure work. Use a clamp, vise or other practical means to hold
your work securely, freeing oth hands to control the tool.
22. Do not force tool. Your tool will perform est at the rate for which
it was designed. Excessive force only causes operator fatigue,
increased wear and reduced control.
23. Use the right tool. Do not use a tool or attachment to do a jo for
which it is not recommended. For example, do not use a circular
saw to cut tree lim s or logs. Do not alter a tool.
24. Unplug tool when it is not in use, efore changing accessories or
performing recommended maintenance.
25. Store idle tools. When not in use, store your tool in a dry, secured
place. Keep out of reach of children.
26. Never leave the tool running unattended. Turn power off. Do
not leave the tool until it comes to a complete stop.
27. Check for damaged parts. Inspect guards and other parts e-
fore use. Check for misalignment, inding of moving parts, improper
mounting, roken parts and any other conditions that may affect
operation. If a normal noise or vi ration occurs, turn the tool off
immediately and have the pro lem corrected efore further use. Do
not use a damaged tool. Tag damaged tools DO NOT USE until
repaired. A guard or other damaged part should e properly repaired
or replaced y a MILWAUKEE service facility. For all repairs, insist
on only identical replacement parts.

1. WARNING! Some dust created y power sanding, sawing, grinding,
drilling, and other construction activities contains chemicals known
to cause cancer, irth defects or other reproductive harm. Some
examples of these chemicals are:
 lead from lead- ased paint
 crystalline silica from ricks and cement and other masonry
products, and
 arsenic and chromium from chemically-treated lum er.
Your risk from these exposures varies, depending on how often
you do this type of work. To reduce your exposure to these chemi-
cals: work in a well ventilated area, and work with approved safety
equipment, such as those dust masks that are specifically designed
to filter out microscopic particles.
2. Always keep hands away from the path of the saw blade.
3. Do not defeat the guards of operate the tool without the
guards in place.
4. Always support work properly. Use the fence, support locks,
auxiliary work support or clamps to keep workpiece secure. Al-
ways support the free end of the workpiece and support all small
workpieces. Workpieces that ow and pinch the lade may result in
kick ack. Do not perform any operations freehand (unsupported).
5. Never reach around, under or across blade.
6. Check guards for smooth operation efore each use.
7. Avoid kick back. Kick ack is a violent reaction to a pinched or
inding lade, which throws the saw head upward and towards
the operator. Proper workpiece selection and support, proper lade
selection and maintenance, and even feed rate are essential to
reduce the risk of kick ack.
8. Always wait for the blade to stop completely before chang-
ing positions, retrieving a cut-off piece, or preparing the next cut.
Unplug the tool efore tightening lade screw, servicing, making
adjustments, transporting or moving the saw to another location.
9. Be sure the clamp handle is tightened securely before
making cuts.
10. Do not use abrasive wheels with the miter saw.
11. Use the right blade. Use only recommended lade types and
sizes with proper mounting holes, rated at least 5500 RPM. Follow
the rotation arrow on the lade to e sure you install it properly.
Keep saw lades sharp to help prevent cracking and gra ing.
Never use defective or incorrect washers or olts.
12. Do not lock the trigger in the on position.
SPECIFIC SAFETY RULES
13. Wait for the blade to reach full speed before lowering the
saw head to make a cut.
14. Keep the cord away from the cutting area and position it so that
it will not e tripped over or caught on the workpiece while you are
cutting.
15. Do not place hands under the saw motor or in the path of
the blade. Do not retrieve a piece of material that is cut off while the
lade is rotating. Never place hands or fingers ehind or in front of
the saw lade.
16. Keep blades clean and sharp. An unsharpened or improperly
sharpened lade produces a narrow kerf and is likely to e pinched
y the workpiece. A dull lade produces excessive friction which
can cause the lade to warp or ind. Be sure the lade screw is
tight to prevent slipping or loosening during operation.
17. Restarting in mid-cut. If you stop the saw in mid-cut, allow the
lade to stop, then raise the saw out of the cut. Then restart the
saw.
18. If the blade stalls, do not turn the switch on and off. A dull
lade or excess pressure may cause stalling. Release the switch
immediately if the lade inds or the saw stalls and remove the saw
from the cut.
19. Avoid cutting nails. Inspect for and remove all nails efore cutting.
20. Thin material tends to warp or sag and must e well-supported
over its entire length to avoid pinching the lade.
21. Position fence properly. Always make sure the fence is
adjusted for the intended cut. Never operate the saw without the
fence in place.
22. Lock the saw head down before transporting.
23. Push the saw through the workpiece. Do not pull the saw
through the workpiece. To make a cut, raise the saw head OVER
the workpiece WITHOUT cutting, start the motor, wait a few sec-
onds for the lade to reach full speed, press down on saw head,
and push saw head through the cut.
SERVICE
31. Tool service must be performed only by qualified repair
personnel. Service or maintenance performed y unqualified per-
sonnel may result in a risk of injury.
32. When servicing a tool, use only identical replacement parts.
follow instructions in the maintenance section of this
manual. Use of unauthorized parts or failure to follow maintenance
instructions may create a risk of shock or injury.
28. Use proper accessories. Consult this manual for recommended
accessories. Using improper accessories may e hazardous. Be
sure accessories are properly installed and maintained. Do not de-
feat a guard or other safety device when installing an accessory or
attachment.
29. Maintain tools carefully. Keep handles dry, clean and free from
oil and grease. Keep cutting edges sharp and clean. Follow instruc-
tions for lu ricating and changing accessories. Periodically inspect
tool cords and extension cords for damage. Have damaged parts
repaired or replaced y a MILWAUKEE service facility.
30. Maintain labels & nameplates. These carry important informa-
tion. If unreada le or missing, contact a MILWAUKEE service facil-
ity for a free replacement.
