General Power Tool Safety Warnings

WARNING: * Read all safety warnings and all instructions. Failure to follow the

warnings and instructions may result in electric shock, fi re and/or serious injury. * 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.WORK AREA SAFETY1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.

2. Do not operate power tools in explosive atmospheres, such as in the presence of fl ammable

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

3. Keep children and bystanders away while operating a power tool. Distractions can cause you

to lose control.ELECTRICAL SAFETY

1. 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. Unmodifi ed plugs and matching outlets will reduce risk of electric shock.

2. 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.

3. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase

the risk of electric shock.

4. 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.

5. 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.

6. 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. NOTE: The term “residual current device (RCD)” may be replaced by the term “ground fault circuit interrupter (GFCl)” or “earth leakage circuit breaker (ELCB)”. 000BookC7WDMNAlowes.indb4000BookC7WDMNAlowes.indb4 2018/03/0916:58:072018/03/0916:58:075 English PERSONAL SAFETY

1. 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 infl uence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.

2. 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.

3. 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 fi nger on the switch or energizing power tools that have the switch on invites accidents.

4. 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.

5. Do not overreach. Keep proper footing and balance at all times. This enables better control

of the power tool in unexpected situations.

6. 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.

7. 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.

POWER TOOL USE AND CARE

1. 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.

2. 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.

3. 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.

4. 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.

5. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts

and any other condition that may aff ect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

6. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting

edges are less likely to bind and are easier to control.

7. 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 diff erent from those intended could result in a hazardous situation. SERVICE

1. Have your power tool serviced by a qualifi ed repair person using only identical replacement

parts. This will ensure that the safety of the power tool is maintained.specially designed for your saw, for optimum performance and safety of operation. 000BookC7WDMNAlowes.indb5000BookC7WDMNAlowes.indb5 2018/03/0916:58:072018/03/0916:58:076 English Safety instructions for all saws CUTTING PROCEDURES

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. NOTE: For curcular saws with 140 mm or smaller diameter blades, the “Keep your second hand on auxiliary handle, or motor housing“ may be omitted.

2. Do not reach underneath the workpiece. The guard cannot protect you from the blade

below the workpiece.

3. 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.

4. Never hold the workpiece 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 minimise body exposure, blade binding, or loss of control.

5. Hold the power tool by insulated gripping surfaces only, when performing an

operation where the cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will also make exposed metal parts of the power tool “live” and could give the operator an electric shock.

6. When ripping, always use a rip fence or straight edge guide. This improves the

accuracy of cut and reduces the chance of blade binding.

7. 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.

8. 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.

SPECIAL SAFETY RULES FOR KICKBACK

1. Kickback causes and related warnings:

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.

2. 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:

Maintain a fi rm 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. 000BookC7WDMNAlowes.indb6000BookC7WDMNAlowes.indb6 2018/03/0916:58:072018/03/0916:58:077 English

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.

When restarting a saw in the workpiece, center the saw blade in the kerf and check that the 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.

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.

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

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

LOWER GUARD FUNCTION

1. Check lower guard for proper closing before each use. Do not operate the saw if the

lower guard does not move freely and close instantly. Never clamp or tie the lower guard into the open position. If the saw is accidentally dropped, the lower guard may be bent. Raise the lower guard with the lower guard lifting lever and make sure it moves freely and does not touch the blade or any other part, in all angles and depths of cut.

2. 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 build-up of debris.

3. The lower guard shall be retracted manually only for special cuts such as “plunge

cuts” and “compound cuts”. Raise the lower guard by the lower guard lifting lever and as soon as the blade enters the material, the lower guard must be released. For all other sawing, the lower guard should operate automatically.

4. Always observe that the lower guard is covering the blade before placing the saw

down on bench or fl oor. 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. OTHERS

1. ALWAYS wear proper apparel. Do not wear loose clothing, gloves, neckties, rings,

bracelets or other jewelry which may get caught in moving parts to lead personal injury. Wear protective hair covering to contain long hair.

2. ALWAYS wear eye protection. Any power tool can throw foreign objects into eyes and could

cause permanent eye damage. ALWAYS wear Safety Goggles (not glasses) that comply with ANSI Safety standard Z87.1. Everyday eyeglasses have only impact–resistant lenses. They ARE NOT safety glasses. 000BookC7WDMNAlowes.indb7000BookC7WDMNAlowes.indb7 2018/03/0916:58:072018/03/0916:58:078 English

3. Wear suitable personal protective equipment when necessary, this could include:

● hearing protection to reduce the risk of induced hearing loss;● eye protection; ● respiratory protection which are approved by NIOSH/OSHA to reduce the risk of inhalation of harmful dust; ● gloves for handling saw blades (saw blades shall be carried in a holder wherever practicable) and rough material.

4. Keep alert. Never operate the saw when you feel tired or when you are under the the

infl uence of any drugs, alcohol or medicationn that could aff ect your ability to use the tool properly.

5. Keep the working environment well ventilated. Some dust created by power sanding,

sawing, grinding, drilling and other construction activities contains chemicals to cause cancer, birth defects or other reproductive harm. Therefore, work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to fi lter out microscopic particles.

6. 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.

7. To prevent from fi re or toxic reactio, never use gasoline, naphtha acetone, lacquer thinner

or similar highly volatile solvents to clean the saw.

SPECIFIC SAFETY RULES AND SYMBOLS

1. Adjustments. Before cutting be sure depth and bevel adjustments are tight.

2. Avoid cutting nails. Inspect for and remove all nails from work piece before cutting.

3. When operating the saw, keep the cord away from the cutting area and position it

so that it will not be caught on the workpiece during the cutting operation. Operate with proper hand support, proper workpiece support, and supply cord routing away from the work area.

It is important to support the work piece properly and to hold the saw fi rmly to prevent loss of control which could cause personal injury. Fig. 1 illustrates typical hand support of the saw. Fig. 1

4. Place the wider portion of the saw base 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, Fig. 2 illustrates the RIGHT way to cut off the end of board, and Fig. 3 the WRONG way. If the work piece is short or small, clamp it down. DON’T TRY TO HOLD SHORT PLACES BY HAND! Fig. 2 Fig. 3

5. Never attempt to saw with the saw held upside down in a vise.

This is extremely dangerous and can lead to serious accidents. (Fig. 4) Fig. 4

6. Before setting the tool down after completing a cut, be sure that the lower blade

guard has closed and the blade has come to a complete stop.

7. Never touch moving parts.

Never place your hands, fi ngers or other body parts near the tool’s moving parts.

8. Never operate without all guards in place.

Never operate this tool without all guards or safety features in place and in proper working order. If maintenance or servicing requires the removal of a guard or safety feature, be sure to replace the guard or safety feature before resuming operation of the tool.

11. Confi rming condition of the environment:

Confi rm that the work site is placed under appropriate conditions conforming to prescribed precautions. Fig. 14 Lower blade guard 000BookC7WDMNAlowes.indb21000BookC7WDMNAlowes.indb21 2018/03/0916:58:292018/03/0916:58:2922 English AFTER CONNECTING THE POWER PLUG TO AN APPROPRIATE AC POWER SOURCE, CHECK THE OPERATION OF THE TOOL AS FOLLOWS:

After confi rming that no one is standing behind, the power tool start and confi rm that no operating abnormalities exist before attempting a cutting operation.

13. Inspect the rotating stability of the saw blade.

For precise cutting, rotate the saw blade and check for defl ection to confi rm that the blade is not noticeably unstable; otherwise vibrations might occur and cause an accident.

14. Prepare a wooden workbench (Fig. 15)

Since the saw blade will extend beyond the lower surface of the workpiece, place the workpiece on a workbench when cutting. If a square block is utilized as a workbench, select level ground to ensure it is properly stabilized. An unstable workbench will result in hazardous operation. CAUTION: To avoid possible accident, always ensure that the portion of workpiece remaining after cutting is securely anchored or held in position.

WARNING: To avoid serious accident, ensure the switch is in the OFF position

and disconnect the plug from the receptacle during maintenance and inspection.

1. Cutting depth adjustment

WARNING: If the depth adjusting locking lever is loose, injury can result. Tighten

it securely after adjustment. (1) Lift the depth adjusting locking lever up to loose. (2) Move the base plate to obtain the desired cutting depth. (3) Setting the saw to an appropriate cutting depth minimizes blade friction, eliminates sawdust from between the teeth of the blade, allows faster cutting, and reduces kickback opportunities. For the most effi cient cutting action, place the material to be cut along the side of the blade and adjust the cutting depth so that the saw blade protrudes one tooth length from the material. NOTE: The scale on the side of the base plate is accurate only with the maximum cutting depth. (4) Press down the depth adjusting locking lever to tighten. NOTE: Always make sure the depth adjustment locking lever is locked in the down position before operating the saw.

5. Installing the rip fence (optional accessories)

(1) Insert the rip fence through the holes of the base plate. (2) Adjust the rip fence to the desired position. (3) Insert and tighten the rip fence locking bolt. Fig. 24 Rip fence Base plate Rip fence locking bolt 000BookC7WDMNAlowes.indb27000BookC7WDMNAlowes.indb27 2018/03/0916:58:402018/03/0916:58:4028 English

WARNING: * To avoid serious accident, ensure the switch is OFF position, and

disconnect the plug from the receptacle before any adjustment.

• To avoid serious accident, make sure that the rip fence does not touch the saw blade before use. Ripping means to cut wider boards into narrower strips – cutting grain lengthwise. Therefore, it is recommended to use the Hitachi rip fence (optional accessory, refer to page 15) to provide the support and cut boards into the same width.

• Never secure the lower blade guard in a raised position. Never move the saw backwards when plunge cutting. This may cause the saw to raise up off the work surface which could cause injury.

• To avoid serious accident, ensure the trigger switch is on the OFF position, and disconnect the plug from the receptacle before any adjustment.

• Never tie or wedge the lower blade guard in a raised position. (1) Mark the desired cutting area clearly with lines all side. (See Fig. 26) (2) Set depth adjustment according to material to be cut. (3) Push the lower blade guard lifting lever all the way back, so the blade is exposed as shown in Fig. 26. (4) Tilt the saw forward and align the guide notch with the pre-marked guide line. (5) Release the lever. When the lower blade guard contacts the workpiece surface, it will be in the proper position to open freely when cutting is commenced. (6) Holding the saw in position, with the blade not contacting the work piece surface, pull the trigger switch. (7) After the saw has reached full speed, gradually lower rear end of the saw until its base plate rests on the work surface. Fig. 25 Rip fence Fig. 26 Trigger switch Lower blade guard lifting lever Auxiliary handle 000BookC7WDMNAlowes.indb28000BookC7WDMNAlowes.indb28 2018/03/0916:58:442018/03/0916:58:4429 English (8) Advance saw along the cutting line up to the corner. (9) Release trigger switch and allow the blade to stop completely before withdrawing the blade from the workpiece. Never under any circumstances pull the saw backwards while the blade is in motion, as kickback may result. (10) Use a jig saw or hand saw to cut the corners out clean. (11) When starting each new cut, repeat as above.

WARNING: Never hold the workpiece in your hands or across your leg while

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

8. Appropriate support for cutting large workpiece

Fig. 27-a DON’T support the large workpiece away from the cut. Fig. 27-b ALWAYS support the large workpiece near the cut. Support Support When the support is away from the cutting path, it may cause the large workpiece to be curved. In such case, the blade is likely to be bound, causing a kickback and increasing the load to the motor. (Fig. 27-a) Therefore, to avoid the possible personal injury or kickback occurred, ALWAYS cut the large workpiece with the appropriate support which shall be near the cutting path. (Fig. 27-b) 000BookC7WDMNAlowes.indb29000BookC7WDMNAlowes.indb29 2018/03/0916:58:472018/03/0916:58:4730 English

MAINTENANCE AND INSPECTION

WARNING: To avoid an accident or personal injury, always confi rm that

the trigger switch is turned OFF and the power plug has been disconnected from the receptacle before performing any maintenance or inspection of this tool.

1. Inspecting the saw blade

Always replace the saw blade immediately upon the fi rst sign of deterioration or damage. A damaged saw blade can cause personal injury and a worn saw blade can cause ineff ective operation and possible overload to the motor. CAUTION: Never use a dull saw blade. When a saw blade is dull, its resistance to the hand pressure applied by the tool handle tends to increase, making it unsafe to operate the power tool.

2. Inspecting the carbon brushes (Fig. 28 and Fig. 29)

The carbon brushes in the motor are expendable parts. If the carbon brushes become excessively worn, motor trouble might occur. Therefore, inspect the carbon brushes periodically and replace them when they have become worn to the wear limit line as shown in Fig. 28. Also, keep the carbon brushes clean so that they will slide smoothly within the brush holders. Use a slotted screwdriver to turn the spring-loaded cap counterclockwise carefully to remove the cap on the side of the motor. Pull out the carbon brush and replace. The ears on the metal end of the assembly go in the same hole the carbon part fi ts into. Last, tighten the cap snugly, but do not overtighten. Repeat above procedure for the carbon brush located on the other side of the motor. NOTE: When replacing the carbon brushes, use only Hitachi carbon brushes. CAUTION: Using this saw with a carbon brush which is worn in excess of the wear limit will damage the motor. Fig. 29 Carbon brushSpring-loeded cap Fig. 28 Wear limit line11/16" (17 mm)1/4" (5.7 mm)
