Symbols WARNING The following show symbols used for the machine. Be sure that you understand their meaning before use. 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. Always wear eye protection. Always wear hearing protection. SAFETY

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.

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 fl ammable 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.

English 00BookC7SB3US.indb300BookC7SB3US.indb3 2017/09/1417:57:392017/09/1417:57:392) 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. Unmodifi ed 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.

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 infl uence 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 fi nger 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. e) 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. 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 diff erent from those intended could result in a hazardous situation.

English 00BookC7SB3US.indb400BookC7SB3US.indb4 2017/09/1417:57:392017/09/1417:57:395) Service a) 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.

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 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. 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. g) Always use blades with correct size and shape (diamond versus round) of arbour 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. 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. 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 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. 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, centre 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 minimise 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. f) 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 function 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.

English 00BookC7SB3US.indb500BookC7SB3US.indb5 2017/09/1417:57:392017/09/1417:57:394. 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 circular 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 (telescoping) guard has closed and the blade has come to a complete stop. 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 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.

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.

NEVER operate, or attempt any maintenance on the tool unless you have fi rst read and understood all safety instructions contained in this manual. Some illustrations in this Instruction Manual may show details or attachments that diff er from those on your own power tool.

The tool is designed for wood cutting applications.

Use extra caution when cutting freshly cut green lumber, hardwood, wet wood, composite wood, pressure treated wood, wood containing knots or having other characteristics which may put a heavy load on the saw or blade. If this occurs, do not force the tool. Push the tool more slowly, but with enough force to keep working without much decrease in speed.

Ensure that the power source to be utilized conforms to the power source requirements specifi ed on the product nameplate.

Ensure that the switch is in the OFF position. If the plug is connected to a receptacle while the switch is in the ON position, the power tool will start operating immediately and can cause serious injury.

When the work area is far away from the power source, use an extension cord of suffi cient thickness and rated capacity. The extension cord should be kept as short as practicable.

Damaged cord must be replaced or repaired.

4. Check the receptacle

If the receptacle only loosely accepts the plug, the receptacle must be repaired. Contact a licensed electrician to make appropriate repairs. If such a faulty receptacle is used, it may cause overheating, resulting in a serious hazard.

5. Confi rming condition of the environment:

Confi rm that the work site is placed under appropriate conditions conforming to prescribed precautions.

6. Prepare a wooden workbench (Fig. 6)

Since the saw blade will extend beyond the lower surface of the work piece, place the work piece 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 work piece remaining after cutting is securely anchored or held in position. Work piece Base Saw Blade Fig. 6 Workbench

If the lever (A) to adjust cutting depth (Fig. 7) and lever (A) to adjust angle of inclination (Fig. 8) are loose, injury can result. Make sure that they are tightened securely.

8. Check performance of lower guard.

Make absolutely sure that the safety cover is not fi xed. Also, check and see if it can move smoothly. If the saw blade is kept exposed injury can result. The lower guard (refer to Fig. 5) serves to protect your body from coming into contact with the saw blade. Make absolutely certain that the cover smoothly performs to cover the saw blade. If the lower guard should not move smoothly, never use it without repairing it. In such a case, get in touch with the store where you bought the circular saw or the HITACHI Authorized Service Center for necessary repair.

Always wear eye protection with side shields that meets the requirements of ANSI Standard Z87.1. Ordinary eyeglasses do not provide adequate protection.

Operating the tool without wearing proper eye protection may result in serious injury.

10. Check if saw blade is tightened

Refer to [mounting and dismounting the saw blade] in Page 14, and make sure that the fl ange bolt is tightened securely.

To avoid serious accidents, ensure the switch is in OFF position, and disconnect the plug from the receptacle.

If the lever (A) is loose, injury can result. Tighten it securely after adjustment. To adjust cutting depth, loosen the lever (A) and, while holding the base with one hand, move the main body up and down to obtain the prescribed cutting depth. After adjusting to the prescribed cutting depth, tighten the lever (A) securely. Lever (A) Link Base Fig. 7 Tighten Loosen

If the lever (A) is loose, injury can result. Tighten it securely after adjustment. You can incline saw blade from 0˚ to a maximum angle of 55˚ in relation to the base. As shown in Fig. 8 by loosing the lever (A) on the bevel scale, the saw blade may be inclined to an angle of 45˚ in relation to the base. If you use inclination angle of over 45˚, as shown in Fig. 9 move the lever (A) to outside, the saw blade may be inclined to a maximum angle of 55˚ in relation to the base. Always ensure that the lever (A) is thoroughly tightened after making the desired adjustment.

3. Regulating the guide (Rip fence) (Fig. 10, 11)

Never touch the moving parts.

Should the saw blade be stopped or make an abnormal noise during operation, turn off the switch immediately.

Don't remove circular saw from work piece during a cut while the saw blade is moving.

Always wear eye protection with side shields that meets the requirements of ANSI Standard Z87.1. Ordinary eyeglasses do not provide adequate protection.

Avoid cutting any material like metal, etc., that give off sparks.

Do not use any abrasive wheels.

Always take care in preventing the power cord from coming near the revolving saw blade.

Before starting to saw, ensure that the saw blade has reached full speed revolution.

1. Place the saw body (base) on the work piece, and as in Fig. 12

align the intended line of cut with the saw blade, using the notch. This relationship of base to work pieces should remain unchanged regardless of the inclination of the base.

2. The switch should be turned to the ON position before the saw blade

comes into contact with the work piece. The switch is turned ON when the trigger is pulled by one’s fi nger, and is turned OFF when the trigger is released.

3. Moving the saw straight at a constant speed will produce optimum

cutting. [POCKET CUTTING]

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

Never tie or wedge the lower guard in a raised position.

1. Mark the desired cutting area clearly with lines all side. (See

2. Set depth adjustment according to material to be cut.

3. Push the lever all the way back so the blade is exposed as shown

4. Tilt saw forward and align the notch (Fig. 12) with the pre-marked

5. Release the lever. When the lower guard contacts the work piece

surface, it will be in 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.

7. After the saw has reached full speed, gradually lower rear end of the saw until its base rests on the work surface.

9. Release trigger and allow blade to stop completely before withdrawing the blade from the work piece.

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.

USING THE CORD HOLDER

By threading the cord through the cord holder, the cord can be set to be drawn in a side direction. (See Fig. 14)

MOUNTING AND DISMOUNTING THE SAW BLADE

To avoid serious accident ensure the switch is in the OFF position, and disconnect the plug from the receptacle.

1. Dismounting the saw blade

(1) Set the cutting volume at maximum, and place the Circular Saw as shown in Fig. 15. (2) Depress the lock lever, lock the spindle, and remove the hexagonal-fl ange bolt and washer (B) with the Hex. Bar wrench. (3) While holding the lever to keep the lower guard fully retracted into the blade cover, remove the saw blade. (Fig. 16)

2. Mounting the saw blade

(1) Thoroughly remove any sawdust which has accumulated on the spindle, bolt and washers. (2) For mounting saw blade, the concave sides of both washers (A) and (B) must be fi tted to the saw blade sides. Mount the saw blade on the spindle, and fi nally affi x washer (B) (See Fig. 17) (3) To assure proper rotation direction of the saw blade, the arrow direction on the saw blade must coincide with the arrow direction on the blade cover. (4) Using the fi ngers, tighten the hexagonal bolt retaining the saw blade as much as possible. Then depress the lock lever, lock the spindle, and thoroughly tighten the bolt. (5) Confi rm that the lock lever is in the original position. Fig. 14 Cord holder Fig. 15 Lock Lever Wrench Loosen Tighten

To avoid serious accident, ensure the switch is in the OFF position and disconnect the plug from the receptacle during maintenance and inspection.

1. Inspecting the saw blade:

Since use of a dull saw blade will degrade effi ciency and cause possible motor malfunction, sharpen or replace the saw blade as soon as abrasion is noted. CAUTION: If a dull saw blade is used, reactive force is increased during cutting operation. Avoid the use of the dull saw blade without repair.

Loose screws are dangerous. Regularly inspect them and make sure they are tight. CAUTION: Using this power tool with loosened screws is extremely dangerous.

3. Inspecting the carbon brushes (Fig. 18)

The motor employs carbon brushes which are consumable parts. Replace the carbon brush with a new one when it becomes worn to its wear limit. Always keep carbon brushes clean and ensure that they slide freely within the brush holders. CAUTION: Using this circular saw with a carbon brush which is worn in excess of the wear limit will damage the motor. NOTE: Use HITACHI carbon brush No. 43 indicated in Fig. 18. Fig. 18 Wear limit No. of carbon brush

English 00BookC7SB3US.indb1500BookC7SB3US.indb15 2017/09/1417:57:402017/09/1417:57:404. Replacing carbon brushes: Remove the brush caps with a slotted-head screwdriver. The carbon brushes can then be easily removed. (Fig. 19)

5. Performance checkup and maintenance of lower guard

Keep the lower guard in good shape for smooth performance at all times. Be sure to make prompt repair in case of any malfunction.

6. Adjusting the base and saw blade to maintain

perpendicularity The angle between the base and the saw blade has been adjusted to 90°, however should this perpendicularity be lost for some reason, adjust in the following manner. (1) Turn the base face up (Fig. 20) and loosen the lever (A). (2) Apply a square to the base and the saw blade and, turning the Hex. socket screw with a Hex. bar wrench, shift the position of the base to produce the desired right angle.

7. Inspecting and maintaining the lower guard

Always make sure that the lower guard moves smoothly. In the event of any malfunction, immediately repair the lower guard. For cleaning and maintenance, use an air gun or other tool to blow clean the space between the lower guard and gear cover as well as the rotation part of the lower guard with dry air (Fig. 21). Doing so is eff ective for the emission of chips or other particles. Accumulation of chips or other particles around the lower guard may result in malfunction or damage.

To prevent dust inhalation or eye irritation, wear protective safety goggles and a dust mask when using an air gun or other tool to clean the lower guard, ventilation holes or other parts of the product.
