Important Safety Instructions
WARNING: When using electric tools, basic safety precautions should always be followed to reduce risk of fire, electric shock, and personal injury, including the following:
READ ALL INSTRUCTIONS
Double Insulation
Double insulated tools are constructed throughout with two separate layers of electrical insula- tion or one double thickness of insulation between you and the tool’s electrical system. Tools built with this insulation system are not intended to be grounded. As a result, your tool is equipped with a two prong plug which permits you to use extension cords without concern for maintaining a ground connection.
NOTE: Double insulation does not take the place of normal safety precautions when operating this tool. The insulation system is for added protection against injury resulting from a possible electrical insulation failure within the tool.
CAUTION: WHEN SERVICING USE ONLY IDENTICAL REPLACEMENT PARTS. Repair or replace damaged cords.
Polarized Plugs
Polarized plugs (one blade is wider than the other) are used on equipment to reduce the risk of electric shock. When provided, this plug will fit in the 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 the proper outlet. Do not change the plug in any way.
Safety Instructions For All Tools
•KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.
•CONSIDER WORK AREA ENVIRONMENT. Don’t expose power tools to rain. Don’t use power tools in damp or wet locations. Keep work area well lit. Do not use tool in presence of flammable liquids or gases.
•GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded surfaces. For example; pipes, radiators, ranges, and refrigerator enclosures.
•KEEP CHILDREN AWAY. Do not let visitors contact tool or extension cord. All visitors should be kept away from work area.
•STORE IDLE TOOLS. When not in use, tools should be stored in dry, and high or
•DON’T FORCE TOOL. It will do the job better and safer at the rate for which it was intend- ed.
•USE RIGHT TOOL. Don’t force small tool or attachment to do the job of a
•DRESS PROPERLY. Do not wear loose clothing or jewelry. They can be caught in moving parts. Rubber gloves and
•USE SAFETY GLASSES. Also use face or dust mask if cutting operation is dusty.
•DON’T ABUSE CORD. Never carry tool by cord or yank it to disconnect from receptacle. Keep cord from heat, oil, and sharp edges.
•SECURE WORK. Use clamps or a vise to hold work. It’s safer than using your hand and it frees both hands to operate tool.
•DON’T OVERREACH. Keep proper footing and balance at all times.
•MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and safer perform- ance. Follow instructions for lubricating and changing accessories. Inspect tool cords period- ically and if damaged, have repaired by authorized service facility. Inspect extension cords periodically and replace if damaged. Keep handles dry, clean, and free from oil and grease.
•DISCONNECT OR LOCK OFF TOOLS when not in use, before servicing, and when changing accessories, such as blades, bits, cutters.
•REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that keys and adjusting wrenches are removed from tool before turning it on.
•AVOID UNINTENTIONAL STARTING. Don’t carry tool with finger on switch. Be sure switch is off when plugging in.
•EXTENSION CORDS. 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 overheat- ing. The following table shows the correct size to use depending on cord length and name- plate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number,
the heavier the cord.

•OUTDOOR USE EXTENSION CORDS. When tool is used outdoors, use only extension cords intended for use outdoors and so marked.
•STAY ALERT. Watch what you are doing. Use common sense. Do not operate tool when you are tired.
•CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is dam- aged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving 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 by an authorized service center unless otherwise indicated elsewhere in this instruction manual. Have defective switches replaced by authorized service center. Do not use tool if switch does not turn it on and off.
Additional Safety Instructions for Circular Saws
CAUTION: When cutting into walls, floors or wherever live electrical wires may be encoun- tered, DO NOT TOUCH ANY METAL PARTS OF THE TOOL! Hold the tool only by insulated grasping surfaces to prevent electric shock if you cut in the live wire.
•KEEP GUARDS IN PLACE AND IN WORKING ORDER. Never wedge or tie lower guard open. Check operation of lower guard before each use. Do not use if lower guard does not close briskly over saw blade.
CAUTION: If saw is dropped, lower guard may be bent, restricting full return.
• KEEP BLADES CLEAN AND SHARP. Sharp blades minimize stalling and kickback.
DANGER: Keep hands away from cutting area. Keep hands away from blades. Do not reach underneath work while blade is rotating. Do not attempt to remove cut material when blade is moving.
CAUTION: Blades coast after turn off.
•SUPPORT LARGE PANELS. Large panels must be supported as shown in Figure 14 to min- imize the risk of blade pinching and kickback. When cutting operation requires the resting of the saw on the work piece, the saw shall be rested on the larger portion and the smaller piece cut off.
•USE RIP FENCE. Always use a rip fence or straight edge guide when ripping.
•GUARD AGAINST KICKBACK. Kickback occurs when the saw stalls rapidly and is driven back towards the operator. Release switch immediately if blade binds or saw stalls. Keep blades sharp. Support large panels as shown in Figure 14. Use fence or straight edge guide when ripping. Don’f force tool. Stay
•LOWER GUARD. Raise lower guard with the retracting handle.
•ADJUSTMENTS. Before cutting be sure depth and bevel adjustments are tight.
•USE ONLY CORRECT BLADES IN MOUNTING. Do not use blades with incorrect size holes. Never use defective or incorrect blade washers or bolts.
•AVOID CUTTING NAILS. Inspect for and remove all nails from lumber before cutting.
CAUTION: Wear appropriate hearing protection during use. Under some conditions and duration of use, noise from this product may contribute to hearing loss.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other con- struction activities contains chemicals known to cause cancer, birth defects or other reproduc- tive harm. Some examples of these chemicals are:
•lead from
•crystalline silica from bricks and cement and other masonry products, and
•arsenic and chromium from
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.
•Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction activities. Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may pro- mote absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disburse dust, which may cause serious and permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection appropriate for the dust exposure. Direct particles away from face and body.
SAVE THESE INSTRUCTIONS
Motor
Your DEWALT tool is powered by a
Electric Brake
Your saw has an automatic electric brake which is designed to stop the blade from coasting in about two seconds after you release the trigger switch. It is useful when making certain cuts in wood where a coasting blade would result in a wide, imprecise cut.
Occasionally, under certain conditions, the brake will not function properly and won’t stop the saw in the 2 seconds discussed above. If this condition persists, turn the saw on and off four or five times. If the brake still does not stop the blade in about 2 seconds, the problem may be worn brushes. Replace the brushes as described below and try the saw again. If the problem still per- sists, have the tool serviced at a DEWALT certified service center.
Brushes
DISCONNECT PLUG FROM POWER SUPPLY
Inspect carbon brushes regularly by unplugging tool, removing the Brush Inspection Cap (A) (Figure 1) and withdrawing the brush assembly. Keep brushes clean and sliding freely in their guides. Always replace a used brush in the same orientation in the holder as it was prior to removal. Carbon brushes have varying symbols stamped into their sides, and if the brushes are worn down to the line closest to the spring, they must be replaced. Use only identical DEWALT brushes. Always replace both brushes. Use of the correct grade of brush is essential for proper operation of electric brakes. New brush assemblies are available at your local DEWALT certified service center. The tool should be allowed to “run in” (run at no load without blade) for 10 minutes before use to seat new brushes. This is especially important for saws equipped with electric brakes, which may be erratic in operation until the brushes are properly seated (worn in).
While “running in” DO NOT TIE, TAPE, OR OTHERWISE LOCK THE TRIGGER SWITCH ON.
HOLD BY HAND ONLY.
Adjustments and Setup
ATTACHING AND REMOVING BLADES (FIG. 2)
DISCONNECT PLUG FROM POWER SUPPLY.
To attach the blade, retract lower blade guard (C) and place inner clamp washer (D) and blade
(E)on saw spindle with teeth at bottom of blade pointing forward. Install outer clamp washer (F). The larger surfaces of both washers must face the blade. Thread on blade clamping screw (G) firmly by hand to hold washers in position.
Lightly depress the blade lock (B) while turning the spindle until the blade stops rotating. Tighten blade clamping screw (clockwise) firmly with the blade wrench (Figure 3).
NEVER ENGAGE BLADE LOCK WHILE SAW IS RUNNING, OR ENGAGE IN AN EFFORT TO STOP THE TOOL. NEVER TURN SWITCH ON WHEN BLADE LOCK IS ENGAGED.
When removing the blade, first unplug the saw. Engage the blade lock and unscrew the blade clamping screw by turning it
CUTTING DEPTH ADJUSTMENT (FIG. 4)
DISCONNECT PLUG FROM POWER SUPPLY.
Loosen (counterclockwise) the Cutting Depth Adjustment Knob (H). Lift the saw handle, as shown, to adjust it to the desired height. Tighten the knob to secure it in place. If depth of cut cannot be adjusted, inspect parts for damage and service as required before use. A scale and pointer (I) is provided to enable you to select a specific depth of cut. Simply align the pointer to the desired depth of cut.
NOTE: To adjust the depth of cut pointer for various blade diameters, loosen the Cutting Depth Adjustment Knob and raise the saw until the blade just touches the workpiece and tighten the knob. This is the zero depth of cut position. If required, loosen the screw that holds the pointer and adjust to the zero indicator mark. The saw is now adjusted to accurately indicate the depth of cut for the blade used.
For the most efficient cutting action using a carbide tipped saw blade, set the Depth Adjustment so that about one half of a tooth projects below the surface of the wood to be cut. The height of a whole tooth is the distance from the tip of the tooth to the bottom of the gullet in front of it. Study Figures 5A and 5B to determine what one half tooth means. (5A shows one half tooth pro- jecting below the surface and figure 5B shows a whole tooth projecting below the surface.)
Setting the saw at the proper cutting depth keeps blade friction to a minimum, removes sawdust from between the blade teeth, results in cooler, faster sawing and reduces the chance of kick- back.
A method of checking for the correct cutting depth is shown in Figure 6. Lay a piece of the mate- rial you plan to cut along the side of the blade, as shown in the figure, and observe how much tooth projects beyond the material.
NOTE: When using a non carbide tipped blade, make an exception to the above procedure and allow a full tooth to project below the material, as shown in Figure 5B.
BEVEL ANGLE ADJUSTMENT (FIG. 7)
DISCONNECT THE SAW FROM THE POWER SUPPLY.
The full range of the Bevel Adjustment is from 0 to 50 DEGREES. The quadrant (J) is graduat- ed in increments of 1 degree.
On the front of the saw is a bevel angle adjustment mechanism consisting of a calibrated quad- rant (J) and a knob, (K). To set the saw for a bevel cut, loosen (counterclockwise) the quadrant
