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

Grounding Instructions

This tool should be grounded while in use to protect the operator from electric shock. The tool is equipped with a 3-conductor cord and 3-prong grounding type plug to ﬁt the proper grounding type receptacle. The green (or green and yellow) conductor in the cord is the grounding wire. Never connect the green (or green and yellow) wire to a live terminal. If your unit is intended for use on less than 150 V, it has a plug that looks like that shown in sketch A. If it is for use on 150 to 250 V, it has a plug that looks like that shown in sketch D. An adapter, sketches B and C, is available for connecting sketch A type plugs to 2-prong receptacles. The green-colored rigid ear, lug, or the like, extending from the adapter must be connected to a permanent ground, such as a properly grounded out-

let box. No adapter is available for a plug as shown in sketch D. ADAPTER SHOWN IN FIGURES B and C IS NOT FOR USE IN CANADA.

Safety Instructions For All Tools

• KEEP WORK AREA CLEAN. Cluttered areas and bench- es 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 locked-up place — out of reach of children.

• DON’T FORCE TOOL. It will do the job better and safer at the rate for which it was intended.

• USE RIGHT TOOL. Don’t force small tool or attachment to do the job of a heavy-duty tool. Don’t use tool for purpose not intended- for example- don’t use circular saw for cutting tree limbs or logs.

• DRESS PROPERLY. Do not wear loose clothing or jewel- ry. They can be caught in moving parts. Rubber gloves and

non-skid footwear are recommended when working outdoors. Wear protective hair covering to contain long hair.

• 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 performance. Follow instructions for lubricating and changing accessories. Inspect tool cords periodically 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. Use only 3-wire extension cords that have 3-prong grounding-type plugs and 3-pole receptacles that accept the tool’s plug. Replace or repair dam-

aged 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 overheating. The following table shows the correct size to use depending on cord length and nameplate 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 damaged 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.

• 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: Some wood contains preservatives such as copper chromium arsenate (CCA) which can be toxic. When cutting these materials extra care should be taken to avoid inhalation and minimize skin contact.

SAVE THESE INSTRUCTIONS

Motor

Your DEWALT tool is powered by a DEWALT motor. Be sure your power supply agrees with nameplate marking. 120 Volts AC/DC means your saw will operate on alternating or direct current. Lower voltage can cause loss of power and can result in overheating. All D

EWALT tools are factory-tested; if this tool does not operate,

check the power supply.

Brushes

DISCONNECT PLUG FROM POWER SUPPLY BEFORE SERVICING

Inspect carbon brushes regularly by unplugging tool, removing the Brush Inspection Cap (Fig. 2) 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 either brush is worn down to the line closest to the spring, they must be replaced. Use only identical D

EWALT

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 elec- trical wires may be encountered, DO NOT TOUCH ANY METAL PARTS OF THE TOOL! Hold the tool only by insulated grasping surfaces to prevent electric shock if you cut into a 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 10 to minimize 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 10. Use fence or straight edge guide when ripping. Don’f force tool. Stay alertexercise control. Don’t remove saw from work during a cut while the blade is moving.

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

DISCONNECT PLUG FROM POWER SUPPLY. To attach the blade, retract lower blade guard and place inner

clamp washer and blade on saw spindle with printed side of blade out (teeth at bottom of blade pointing forward) (FIG. 1.) Place outer clamp washer on saw spindle. The larger surfaces of both washers must face the blade. Thread on blade clamping screw firmly by hand to hold both blade washers in position. Depress lock pin and tighten blade screw (counterclockwise) with blade wrench.

Changing Blades

CAUTION: Always disconnect saw from power supply before changing blades.

1. Depress LOCK PIN, which runs through the center of the oil ﬁller plug, and turn blade until the LOCK PIN locks ﬁrmly into the saw shaft.

2. With blade wrench, loosen and remove the blade bolt by turning it in a clockwise direction when facing blade (left hand thread). Retract lower blade guard and remove blade.

3. When mounting new blade, the teeth must point in the direction of blade rotation. Replace and tighten the blade bolt as much as possible with the ﬁngers, then tighten ﬁrmly with the blade wrench. Your NEW D

EWALT saw is equipped to

accept blades with either round or diamond arbor holes.

To adapt the saw for use with blades having round arbor holes, simply remove the diamond inner clamp washer and replace with round arbor clamp washer #63243 available at extra cost from your service center.

CUTTING DEPTH ADJUSTMENT

DISCONNECT PLUG FROM POWER SUPPLY. Hold the saw ﬁrmly as shown in Figure 4. Raise to loosen the

depth adjustment lever and move shoe to obtain the desired depth of cut, as shown in Figure 5. Make sure the depth adjustment lever has been retightened (lowered) before operating saw.

Your saw is equipped with a carbide tipped saw blade for long life and efﬁcient cutting.

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 projecting 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 kickback.

A method of checking for the correct cutting depth is shown in Figure 6. Lay a piece of the material 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

DISCONNECT THE SAW FROM THE POWER SUPPLY. The full range of the bevel adjustment is from 0 TO 45 DEGREES.

BLADE GUIDE ADJUSTMENTS

TURN OFF TOOL AND DISCONNECT FROM POWER SUPPLY.

1. With the saw bevel adjustment set on 90°, retract the blade guard and place a straight edge guard against the inside of the blade.

2. Hold the saw handles in normal operating position and align the 90° blade guide notch with the straight edge (Figure 8), then tighten the screw.

3. Take a scrap piece of wood and make a cut to see if the saw cuts where you want before doing any work.

Operation

SWITCH

Pull the trigger switch to turn the motor ON. Releasing the trigger turns the motor OFF. This tool has no provision to lock the switch in the ON position, and should never be locked ON in any way.

WORKPIECE SUPPORT

Figure 9 shows proper sawing position. Note that hands are kept away from cutting area, and power cord is positioned clear of the cutting area so that it will not get caught or hung up on the work.

To avoid kickback, DO support board or panel NEAR the cut, (Figure 10). DON’T support board or panel away from the cut (Figure 11).

When operating the saw, keep the cord away from the cutting area and prevent it from becoming hung up on the work piece.

WARNING: It is important to support the work properly and to hold the saw ﬁrmly to prevent loss of control which could cause personal injury; Figure 12 illustrates typical hand support of the saw.

ALWAYS DISCONNECT SAW BEFORE MAKING ANY ADJUSTMENTS! Place the work with its “good” side - the one on which appearance is most important - down. The saw cuts upward, so any splintering will be on the work face that is up when you saw it.

158629-03/dw377 5/17/02 3:08 PM Page 8

Page 12

CUTTING

Support the work so that the cut will be on your left. Place the wider portion of the saw shoe on that part of the work piece which is solidly supported, not on the section that will fall off when the cut is made. As examples, Figure 12 illustrates the RIGHT way to cut off the end of a board, and Figure 13 the WRONG way. Always clamp work. Don’t try to hold short pieces by hand! Remember to support cantilevered and overhanging material. Use caution when sawing material from below.

Be sure saw is up to full speed before blade contacts material to be cut. Starting saw with blade against material to be cut or pushed forward into kerf can result in kickback.

Push the saw forward at a speed which allows the blade to cut without laboring. Hardness and toughness can vary even in the same piece of material, and knotty or damp sections can put a heavy load on the saw. When this happens, push the saw more slowly, but hard enough to keep it working without much decrease in speed.

Lubrication

1. Always check oil level before using the saw. To check the oil level, lay the saw down on the blade side, as shown in Figure 14 and remove the oil ﬁller plug. Lay the oil ﬁller plug on its side under the top edge of the blade guard as shown in the ﬁgure. This procedure ensures that the saw is level so that the oil can be checked accurately. If the saw is adequately lubricated, oil will be visible at lower edge of the oil ﬁller hole within 25 seconds. If oil does not appear in this time, the saw requires lubrication.

2. To lubricate the saw, stand it on its handle end. Add lubricant to the oil ﬁller hole, checking frequently as described above to determine when the proper level is reached. If you accidentally overﬁll the saw, lay it on its side and permit the excess to

leak out until the proper level is obtained. DO NOT OVERFILL SAW! Pressure generated by the gears in an overﬁlled saw will force lubricant through the seals causing eventual gear failure and, possibly, motor damage (See special lubricant on page 9).

NOTE: With a new saw, change the oil after the ﬁrst 10 hours of use and once per year after that.

Kickback

When the saw blade becomes pinched or twisted in the cut, kickback can occur. The saw is thrust rapidly back toward the operator. When the blade is pinched or bound tightly by the kerf closing down, the blade stalls and the motor reaction drives the unit backward. When the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into the top surface of the wood causing the blade to climb out of the kerf and jump back toward the operator. Kickback is more likely to occur when any of the following conditions exist.

1. IMPROPER WORKPIECE SUPPORT A. Sagging or improper lifting of the cut off piece causing pinch-

ing of the blade.

B. Cutting through material supported at the outer ends only

(see Figure 11). As the material weakens it sags, closing down the kerf and pinching the blade.

C. Cutting off a cantilevered or overhanging piece of material

from the bottom up in a vertical direction. The falling cut off piece can pinch the blade.

D. Cutting off long narrow strips (as in ripping). The cut off strip

can sag or twist closing the kerf and pinching the blade.

E. Snagging the lower guard on a surface below the material

being cut momentarily reducing operator control. The saw can lift partially out of the cut increasing the chance of blade twist.

158629-03/dw377 5/17/02 3:08 PM Page 9

Page 13

2. IMPROPER DEPTH OF CUT SETTING ON SAW Using the saw with an excessive depth of cut setting increases loading on the unit and susceptibility to twisting of the blade in the kerf. It also increases the surface area of the blade available for pinching under conditions of kerf close down.

3. BLADE TWISTING (MISALIGNMENT IN CUT) A. Pushing harder to cut through a knot, a nail, or a hard grain

area can cause the blade to twist.

B. Trying to turn the saw in the cut (trying to get back on the

marked line) can cause blade twist

C. Extended reach or operating saw with poor body control (out

of balance), can result in twisting the blade.

D. Changing hand grip or body position while cutting can result

in blade twist.

E. Backing unit up to clear blade can lead to twist if not done

carefully.

4. MATERIALS THAT REQUIRE EXTRA ATTENTION

A. Wet lumber B. Green lumber (material freshly cut or not kiln dried)

C. Pressure treated lumber (material treated with preservatives

or anti-rot chemicals)

5. USE OF DULL OR DIRTY BLADES Dull blades cause increased loading of the saw. To compensate, an operator will usually push harder which further loads the unit and promotes twisting of the blade in the kerf. Worn blades may also have insufﬁcient body clearance which increases the chance of binding and increased loading.

6. LIFTING THE SAW WHEN MAKING BEVEL CUTS Bevel cuts require special operator attention to proper cutting techniques - especially guidance of the saw. Both blade angle to the shoe and greater blade surface in the material increase the chance for binding and misalignment (twist) to occur.

7. RESTARTING A CUT WITH THE BLADE TEETH JAMMED AGAINST THE MATERIAL

The saw should be brought up to full operating speed before starting a cut or restarting a cut after the unit has been stopped with the blade in the kerf. Failure to do so can cause stalling and kickback.

Any other conditions which could result in pinching, binding, twisting, or misalignment of the blade could cause kickback. Refer to the sections on “Adjustments And Set-Up” and “Operation” for procedures and techniques that will minimize the occurrence of kickback.

Blades

A dull blade will cause slow, inefﬁcient cutting, overload on the saw motor, excessive splintering and increase the possibility of kickback. It is a good practice to keep extra blades on hand so that sharp blades are available while the dull ones are being sharpened (See SAWS-SHARPENING in the yellow pages). In fact, many lower priced blades can be replaced with new ones at very little cost over the sharpening price.

Hardened gum on the blade will slow down the cutting. This gum can best be removed with trichlorethylene, kerosene, turpentine or oven cleaner.

DeWalt manufactures a complete line of 7-1/4" diameter saw blades and the following types of blades are available from your service center.
