WARNING! Read all safety warnings and all instructions Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

1

SAVE ALL WARNINGS AND INSTRUCTIONS FOR

FUTURE REFERENCE

The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

1) WORK AREA SAFETY a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.

b) Do not operate power tools in explosive atmospheres, such as in the

presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

c) Keep children and bystanders away while operating a power tool.

Distractions can cause you to lose control.

2) ELECTRICAL SAFETY a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools.

Unmodified plugs and matching outlets will reduce risk of electric shock.

b) Avoid body contact with earthed or grounded surfaces such as pipes,

radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges

or moving parts. Damaged or entangled cords increase the risk of electric shock. e) When operating a power tool outdoors, use an extension cord suitable

for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. f) If operating a power tool in a damp location is unavoidable, use a residual

current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

3) PERSONAL SAFETY a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or

under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.

b) Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

c) Prevent unintentional starting. Ensure the switch is in the off position before connecting to power source and/or battery pack, picking up or

carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.

d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair,

clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts. g) If devices are provided for the connection of dust extraction and collection

facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.

4) POWER TOOL USE AND CARE a) Do not force the power tool. Use the correct power tool for your

application. The correct power tool will do the job better and safer at the rate for which it was designed.

b) Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

c) Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories,

or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the

power tool. Power tools are dangerous in the hands of untrained users.

2

e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s

operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

g) Use the power tool, accessories and tool bits, etc., in accordance with these instructions, taking into account the working conditions and the work

to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

5) BATTERY TOOL USE AND CARE a) Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.

b) Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.

c) When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects that

can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.

d) Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts

eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

6) SERVICE a) Have your power tool serviced by a qualified repair person using only

identical replacement parts. This will ensure that the safety of the power tool is maintained.

Electrical Safety

The electric motor has been designed for one voltage range only. Always check that the power supply corresponds to the voltage on the rating plate. 220–240 V AC means your tool will operate on alternating current. Operation at a voltage outside this range can cause loss of power and can result in overheating. All D

E

WALT tools are factory tested; if this tool does not operate, check the power supply. Your D

E

WALT tool is double insulated, therefore no earth wire is required.

• Young children and the infirm. This appliance is not intended for use by young children or infirm persons without supervision.

– This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

– Children should be supervised to ensure that they do not play with the appliance.

• Replacement of the supply cord. If the supply cord or plug is damaged, it must be replaced by the manufacturer or an authorised D E WALT Service Centre in order to avoid a hazard.

Extension Cords

CAUTION: Use only extension cords that are approved by the country’s Electrical

Authority. Before using extension cords, inspect them for loose or exposed wires, damaged insulation and defective fittings. Replace the cord if necessary.

Safety Instructions for All Saws

a) DANGER: Keep hands away from cutting area and the blade. Keep

your second hand on auxiliary handle, or motor housing. If both hands are holding the saw, they cannot be cut by the blade.

b) Do not reach underneath the workpiece. The guard cannot protect you from the blade below the workpiece.

c) Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of the blade teeth should be visible below the workpiece.

d) Never hold piece being cut in your hands or across your leg. Secure the

workpiece to a stable platform. It is important to support the work properly to minimize body exposure, blade binding, or loss of control.

e) Hold power tool by insulated gripping surfaces when performing an

operation where the cutting tool may contact hidden wiring. Contact with a “live” wire will also make exposed metal parts of the power tool “live” and shock the operator.

f) When ripping always use a rip fence or straight edge guide. This improves the accuracy of cut and reduces the chance of blade binding.

3

g) Always use blades with correct size and shape (diamond versus round) of

arbor holes. Blades that do not match the mounting hardware of the saw will run eccentrically, causing loss of control.

h) Never use damaged or incorrect blade washers or bolt. The blade washers and bolt were specially designed for your saw, for optimum performance and safety of operation.

Further Safety Instructions for All Saws

CAUSES AND OPERATOR PREVENTION OF KICKBACK:

• Kickback is a sudden reaction to a pinched, bound or misaligned saw blade, causing an uncontrolled saw to lift up and out of the workpiece 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 rapidly back toward the operator;

• If 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 the result of saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below: a) Maintain a firm grip with both hands on the saw and position your arms to resist kickback forces. Position your body to either side of the blade, but

not in line with the blade. Kickback could cause the saw to jump backwards, but kickback forces can be controlled by the operator, if proper precautions are taken.

b) When blade is binding, or when interrupting a cut for any reason, release the trigger and hold the saw motionless in the material until the blade comes to a complete stop. Never attempt to remove the saw from the work or pull the saw backward while the blade is in motion or kickback may

occur. Investigate and take corrective actions to eliminate the cause of blade binding.

c) When restarting a saw in the workpiece, center the saw blade in the kerf

and check that saw teeth are not engaged into the material. If saw blade is binding, it may walk up or kickback from the workpiece as the saw is restarted.

d) Support large panels to minimize the risk of blade pinching and kickback.

Large panels tend to sag under their own weight. Supports must be placed under the panel on both sides, near the line of cut and near the edge of the panel.

e) Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding and kickback.

Blade depth and bevel adjusting locking levers must be tight and secure

before making cut. If blade adjustment shifts while cutting, it may cause binding and kickback.

g) Use extra caution when sawing into existing walls or other blind areas. The protruding blade may cut objects that can cause kickback.

LOWER GUARD SAFETY INSTRUCTIONS a) Check lower guard for proper closing before each use. Do not operate the saw if lower guard does not move freely and close instantly. Never clamp

or tie the lower guard into the open position. If saw is accidentally dropped, lower guard may be bent. Raise the lower guard with the retracting handle and make sure it moves freely and does not touch the blade or any other part, in all angles and depths of cut.

b) Check the operation of the lower guard spring. If the guard and the spring

are not operating properly, they must be serviced before use. Lower guard may operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris.

c) Lower guard should be retracted manually only for special cuts such as

“plunge cuts” and “compound cuts.” Raise lower guard by retracting handle and as soon as blade enters the material, the lower guard must be

released. For all other sawing, the lower guard should operate automatically.

d) Always observe that the lower guard is covering the blade before placing

saw down on bench or floor. An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in its path. Be aware of the time it takes for the blade to stop after switch is released.

NOTE: Although the above information references wood, this saw is only to be used to cut metal. Kickback can occur when cutting metal.

Additional Specific Safety Instructions for Circular Saws

WARNING: Do not use abrasive wheels or blades.

WARNING: Do not use water feed attachments.

CAUTION: Do not attempt to cut stainless steel, rebar, hardened or heat-treated steel, cast iron, masonry or unknown materials

• Use clamps or another practical way to secure and support the workpiece

to a stable platform. Holding the work by hand or against your body leaves it unstable and may lead to loss of control.

• Keep your body positioned to either side of the blade, but not in line with the

saw blade. KICKBACK could cause the saw to jump backwards (see Causes and

Operator Prevention of Kickback and KICKBACK).

• Air vents often cover moving parts and should be avoided. Loose clothes, jewelry or long hair can be caught in moving parts.

WARNING: We recommend the use of a residual current device with a residual current rating of 30mA or less.

WARNING: ALWAYS wear approved protective safety equipment complying with the following standards:

• Eye protection: AS/NZS1337 Eye Protectors for Industrial Applications;

• Hearing protection: AS/NZS1270 Acoustics – Hearing Protection;

• Respiratory protection: AS/NZS1716 Respiratory Protective Devices.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other masonry products, and

• arsenic and chromium from chemically-treated lumber.

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 promote 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 AS/NZS1716 approved respiratory protection appropriate for the dust exposure. Direct particles away from face and body.

WARNING: Always wear proper personal hearing protection that conforms to

Charge Indicators

This charger is designed to detect certain problems that can arise. Problems are indicated by the red light flashing at a fast rate. If this occurs, re-insert the battery pack into the charger. If the problem persists, try a different battery pack to determine if the charger is working properly. If the new pack charges correctly, then the original pack is defective and should be returned to a service center or other collection site for recycling. If the new battery pack elicits the same trouble indication as the original, have the charger and the battery pack tested at an authorized service center.

7

HOT/COLD DELAY

This charger has a hot/cold delay feature: when the charger detects a battery that is hot, it automatically starts a delay, suspending charging until the battery has cooled.

After the battery has cooled, the charger automatically switches to the pack charging mode. This feature ensures maximum battery life. The red light flashes long, then short while in the hot/cold delay mode.

LEAVING THE BATTERY PACK IN THE CHARGER

The charger and battery pack can be left connected with the charge indicator showing

Pack Charged.

WEAK BATTERY PACKS: Weak batteries will continue to function but should not be expected to perform as much work.

FAULTY BATTERY PACKS: This charger will not charge a faulty battery pack. The charger will indicate faulty battery pack by refusing to light or by displaying problem pack or charger.

NOTE: This could also mean a problem with a charger.

PROBLEM POWER LINE

Some chargers have a Problem Powerline indicator. When the charger is used with some portable power sources such as generators or sources that convert DC to AC, the charger may temporarily suspend operation, flashing the red light with two fast blinks followed by a pause. This indicates the power source is out of limits.

Important Charging Notes

1. Longest life and best performance can be obtained if the battery pack is charged when the air temperature is between 18 ° – 24 °C (65 °F and 75 °F). DO NOT charge the battery pack in an air temperature below +4 °C (+40 °F), or above

+40 °C (+105 °F). This is important and will prevent serious damage to the battery pack.

2. The charger and battery pack may become warm to the touch while charging.

This is a normal condition, and does not indicate a problem. To facilitate the cooling of the battery pack after use, avoid placing the charger or battery pack in a warm environment such as in a metal shed or an uninsulated trailer.

3. A cold battery pack will charge at about half the rate of a warm battery pack. The battery pack will charge at that slower rate throughout the entire charging cycle and will not return to maximum charge rate even if the battery pack warms.

4. If the battery pack does not charge properly:

a. Check operation of receptacle by plugging in a lamp or other appliance;

b. Check to see if receptacle is connected to a light switch which turns power off when you turn out the lights;

c. Move the charger and battery pack to a location where the surrounding air temperature is approximately 18 ˚– 24 ˚C (65 ˚F and 75 ˚F);

d. If charging problems persist, take the tool, battery pack and charger to your local service center.

5. The battery pack should be recharged when it fails to produce sufficient power on jobs which were easily done previously. DO NOT CONTINUE to use under these conditions. Follow the charging procedure. You may also charge a partially used pack whenever you desire with no adverse effect on the battery pack.

6. Foreign materials of a conductive nature such as, but not limited to, grinding dust, metal chips, steel wool, aluminum foil, or any buildup of metallic particles should be kept away from charger cavities. Always unplug the charger from the power supply when there is no battery pack in the cavity. Unplug the charger before attempting to clean.

7. Do not freeze or immerse the charger in water or any other liquid.

WARNING: Shock hazard. Don’t allow any liquid to get inside the charger. Electric shock may result.

WARNING: Burn hazard. Do not submerge the battery pack in any liquid or allow any liquid to enter the battery pack. Never attempt to open the battery pack for any reason. If the plastic housing of the battery pack breaks or cracks, return to a service center for recycling.

Storage Recommendations

1. The best storage place is one that is cool and dry, away from direct sunlight and excess heat or cold.

2. For long storage, it is recommended to store a fully charged battery pack in a cool dry place out of the charger for optimal results.

NOTE: Battery packs should not be stored completely depleted of charge. The battery pack will need to be recharged before use.

TO REPLACE THE BLADE

1. To loosen the blade clamping screw (F), depress the blade lock button (D) and turn the saw spindle with the blade wrench until the blade lock engages and the blade stops rotating. With the blade lock engaged, turn the blade clamping screw clockwise with the blade wrench (screw has left-hand threads and must be turned clockwise to loosen).

2. Remove the blade clamping screw (F) and outer clamp washer (R) only. Remove old blade.

3. Clean any metal chips/shavings that may have accumulated in the guard or clamp washer area and check the condition and operation of the lower blade guard as previously outlined. Do not lubricate this area.

4. Select the proper blade for the application (see Blades). Always use blades that are the correct size (diameter) with the proper size and shape center hole for mounting on the saw spindle. Always assure that the maximum recommended speed (rpm) on the saw blade meets or exceeds the speed (rpm) of the saw.

5. Follow steps 2 through 6 under To Install the Blade, making sure that the blade will rotate in the proper direction.

LOWER BLADE GUARD

WARNING: Under certain conditions of use, metal chips may become imbedded in the surfaces of the lower guard, causing the lower guard to rub against the upper guard. Check the operation of the lower guard before each use and remove any imbedded chips.

WARNING: The lower blade guard is a safety feature which reduces the risk of serious personal injury. Never use the saw if the lower guard is missing, damaged, misassembled or not working properly. Do not rely on the lower blade guard to protect you under all circumstances. Your safety depends on following all warnings and precautions as well as proper operation of the saw. Check lower

guard for proper closing before each use as outlined in Additional Safety Rules for

Circular Saws. If the lower blade guard is missing or not working properly, have the saw serviced before using. To assure product safety and reliability, repair, maintenance and adjustment should be performed by an authorized service center or other qualified service organization, always using identical replacement parts.

Blades

WARNING: To minimize the risk of eye injury, always use eye protection. Carbide is a hard but brittle material. Foreign objects in the workpiece such as wire or nails can cause tips to crack or break. Only operate saw when proper saw blade guard is in place. Mount blade securely in proper rotation before using, and always use a clean, sharp blade.

KICKBACK

Kickback is a sudden reaction to a pinched, bound or misaligned saw blade, causing an uncontrolled saw to lift up and out of the workpiece 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 rapidly back toward the operator. If 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 material causing the blade to climb out of the kerf and jump back toward the operator.

12

Kickback is more likely to occur when any of the following conditions exists.

1. IMPROPER WORKPIECE SUPPORT

A. Sagging or improper lifting of the cut off piece can cause pinching of the blade and lead to kickback (Fig. 9).

B. Cutting through material supported at the outer ends only can cause kickback.

As the material weakens it sags, closing down the kerf and pinching the blade

(Fig. 9).

C. Cutting off a cantilevered or overhanging piece of material from the bottom up in a vertical direction can cause kickback. The falling cut off piece can pinch the blade.

D. Cutting off long narrow strips can cause kickback. 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 reduces operator control. The saw can lift partially out of the cut increasing the chance of blade twist.

2. IMPROPER DEPTH OF CUT SETTING ON SAW

To make the most efficient cut, the blade should protrude only far enough to expose a tooth as shown in Figure 8. This allows the shoe to support the blade and minimizes twisting and pinching in the material. See the section titled Cutting

Depth Adjustment.

3. BLADE TWISTING (MISALIGNMENT IN CUT)

A. Pushing harder to cut 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. Overreaching or operating the 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 up the saw to clear blade can lead to twist.

4. 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.

5. 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 Further Safety Instructions

for All Saws and Blades for procedures and techniques that will minimize the occurrence of kickback.

Depth Adjustment (Fig. 7, 8)

WARNING: To reduce the risk of injury, turn unit off and disconnect it from power source before installing and removing accessories, before adjusting or

when making repairs. An accidental start-up can cause injury.

The metal-cutting saw is equipped with a pivoting shoe that allows the operator to set the depth of cut. For the most efficient cutting action, set the depth adjustment so that one tooth of the blade projects below the material to be cut. This distance is from the tip of the tooth to the bottom of the gullet in front of the tooth. This keeps blade friction at a minimum, removes metal chips from the cut, results in cooler, faster sawing and reduces the chance of kickback.

FIG. 7 FIG. 8

TO SET THE DEPTH OF CUT

1. Lay the piece of material you plan to cut along the blade as shown.

2. Note how much tooth projects beyond the material.

3. Loosen the depth adjustment lever (C) and move the shoe to change the depth of cut.

4. Retighten the depth adjustment lever securely.

Workpiece Support (Fig. 9)

CUTTING SHEETS OF METAL

Figure 9 shows the correct and incorrect way to support a large sheet. To avoid kickback, support material near the cut. Do not support it away from the cut. If material is supported away from the cut, it will bind the blade and cause kickback.

When cutting thin strips, keep the blade at least 1/2" (approximately 13 mm) from the edge of the material. Thin strips may bind, causing kickback and increasing the risk of personal injury.

FIG. 9

CUTTING RECTANGULAR METAL STOCK

Clamp the material you plan to cut to a workbench or other work surface as shown above.

Cutting (Fig. 10, 11)

1. Hold the saw securely using both hands. Figure 10 shows appropriate hand position. Keep your body to one side of the line along which you are cutting. This will protect you from injury related to kickback.

2. When cutting ends off of rectangular FIG. 10 metal stock, place the widest part of the shoe on the part of the material that is clamped to the workbench or other support, not on the part of the material that will fall when the cut is made.

3. Depress the trigger switch and allow the saw to reach full speed before the blade contacts the material to be cut (Fig. 11).

4. Push the saw forward at a speed that allows the blade to cut without laboring.

5. As you finish a cut, release the trigger and allow the blade to stop before lifting the saw from the work. As you lift the saw, the guard will automatically close under the blade.

CORRECTING A CUT

Should your cut begin to leave the cutting line, don’t try to force it back on. Forcing a correction can stall the saw and cause kickback. Instead, release the switch and allow the blade to come to a complete stop. Then, back the saw out of the cut. Restart the saw and re-enter the cut, following the desired cutting line.

CAUTION: Do not cut through bolts with the metal-cutting saw. Damage to the saw or personal injury could result.

Maximizing Blade Life

To extend blade life, follow these practices:

• Do not force the blade through the metal. The saw must cut at its own pace and at a constant rate.

• Change blades when it is no longer easy to push the saw through the cut, when the motor is straining, or when excessive heat is built up in the blade.

• Keep base of the saw firmly against metal you are cutting.

• If the metal you are cutting is vibrating or shaking, clamp the material as close to the cut as possible and slow down the cutting rate.

MAINTENANCE

WARNING: To reduce the risk of injury, turn unit off and disconnect it from power source before installing and removing accessories, before adjusting or

when making repairs. An accidental start-up can cause injury.

Replacing Sight Window (Fig. 1)

WARNING: Do not operate the saw with a damaged or missing sight window.

If window is damaged or missing, have the saw serviced at an authorized service center. If the saw is operated without the window, metal chips could fly through the guard and cause personal injury.

The sight window (J) must be replaced by an authorized D E WALT service center.
