Most accidents that result from power tool operation and maintenance are caused by the failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing a potentially hazardous situation before it occurs, and by observing appropriate safety procedures. Basic safety precautions are outlined in the “SAFETY” section of this Instruction Manual and in the sections which contain the operation and maintenance instructions. Hazards that must be avoided to prevent bodily injury or machine damage are identified by WARNINGS on the power tool and in this Instruction Manual. NEVER use this power tool in a manner that has not been specifically recommended by HITACHI.

MEANINGS OF SIGNAL WORDS

WARNING indicates a potentially hazardous situations which, if ignored, could result in death or serious injury. CAUTION indicates a potentially hazardous situations which, if not avoided, may result in minor or moderate injury, or may cause machine damage. NOTE emphasizes essential information.English

WARNING: Read and understand all instructions.

Failure to follow all instructions listed below, may result in electric shock, fire and/or serious personal injury.

SAVE THESE INSTRUCTIONS

(1) Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents. (2) 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 of fumes. (3) Keep bystanders children, and visitors away while operating a power tool. Distractions can cause you to lose control.

2. Electrical Safety

(1) Double Insulated tools are equipped with a polarized plug (one blade is wider than the other.) This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way. Double Insulation eliminates the need for the three wire grounded power cord and grounded power supply system. (2) Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is 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 to carry the tools or pull the plug from a receptacle. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock. (5) When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”. These cords are rated for outdoor use and reduce the risk of electric shock.

(1) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tires or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury. (2) Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts. (3) Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with your finger on the switch or plugging in tools that have the switch on invites accidents. (4) Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury. (5) Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations. (6) Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.English

(1) Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control. (2) Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed. (3) Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with the switch is dangerous and must be repaired. (4) Disconnect the plug form the power source before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally. (5) Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users. (6) Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools, with sharp cutting edges are less likely to bind and are easier to control. (7) Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool's operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools. (8) Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool, may become hazardous when used with another tool.

(1) Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury. (2) When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instruction may create a risk of electric shock or injury.

such as an underground wiring. Touching live wiring or electric cable with this tool may result in electric shock. Confirm before use whether hidden objects are present, such as electric cables within the wall, floor or ceiling.

To ensure safer operation of this power tool, HITACHI has adopted a double insulation design. “Double insulation” means that two physically separated insulation systems have been used to insulate the electrically conductive materials connected to the power supply from the outer frame handled by the operator. Therefore, either the symbol

” or the words “Double insulation” appear on the power tool or on the nameplate. Although this system has no external grounding, you must still follow the normal electrical safety precautions given in this Instruction Manual, including not using the power tool in wet environments. To keep the double insulation system effective, follow these precautions: 䡬 Only Hitachi Authorized Service Center should disassemble or assemble this power tool, and only genuine HITACHI replacement parts should be installed. 䡬 Clean the exterior of the power tool only with a soft cloth moistened with soapy water, and dry thoroughly. Never use solvents, gasoline or thinners on plastic components; otherwise the plastic may dissolve.English

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 fautly receptacle is used, it may cause overheating, resulting in a serious hazard.

5. Confirming condition of the

environment: Confirm that the work site is placed under appropriate conditions conforming to prescribed precautions.

6. Mounting the blade

This unit employs a detachable mechanism that enables mounting and removal of saw blades without the use of a wrench or other tools. (1) Turn on and off the switching trigger several times so that the lever can jump out of the front cover completely. Thereafter, turn off the switch and unplug the power cord. (Fig. 2)English

CAUTION: Be absolutely sure to keep the switch turned off and the power cord unplugged to prevent any accident. (2) Push the lever in the direction of the arrow mark shown in Fig. 3 marked on the lever. (3) Insert the saw blade all the way into the small slit of the plunger tip with the lever pushing. You can mount this blade either in the upward or downward direction. (Fig. 4, Fig. 5) (4) When you release the lever, the spring force will return the lever to the correct position automatically. (Fig. 6) (5) Pull the back of the saw blade two or three times by hand and check that the blade is securely mounted. When pulling the blade, you will know it is properly mounted if it clicks and the lever moves slightly. (Fig. 7) Lever Front cover Fig. 2 Lever Fig. 3 Blade Fig. 5 Slit of plunger Lever Fig. 6 Fig. 7 Blade Lever Fig. 4 Slit of plunger BladeEnglish

CAUTION: When pulling the saw blade, be absolutely sure to pull it from the back. Pulling other parts of the blade will result in an injury.

7. Dismounting the blade

(1) Turn on and off the switching trigger several times so that the lever can jump out of the front cover completely. Thereafter, turn off the switch and unplug the power cord. (Fig. 2) CAUTION: Be absolutely sure to keep the switch turned off and the power cord unplugged to prevent any accident. (2) After you have pushed the lever in the direction of the arrow mark shown in Fig. 3, turn the blade so it faces downward. The blade should fall out by itself. If the blade doesn’t fall out, pull it out by hand. CAUTION: Never touch the saw blade immediately after use. The metal is hot and can easily burn your skin.

WHEN THE BLADE IS BROKEN

Even when the saw blade is broken and remains inside the small slit of the plunger, it should fall out if you push the lever in the direction of the arrow mark, and face the blade downward. If it doesn’t fall out itself, take it out using the procedures explained below. (1) If a part of the broken saw blade is sticking out of the small slit of the plunger, pull out the protruding part and take the blade out. (2) If the broken saw blade is hidden inside the small slit, hook the broken blade using a tip of another saw blade and take it out. (Fig. 8)

(1) After use, blow away sawdust, earth, sand, moisture, etc., with air or brush them away with a brush, etc., to ensure that the blade mount can function smoothly. (2) As shown in Fig. 9, carry out lubrication around the blade holder on a periodic basis by use of cutting fluid, etc. NOTE: Continued use of the tool without cleaning and lubricating the area where the saw blade is installed can result in some slack movement of the lever due to accumulated sawdust and chips. Under the circumstances, pull a rubber cap provided on the lever in the direction of an arrow mark as shown in Fig. 10 and remove the rubber cap from the lever. Then, clean up the inside of the blade holder with air and the like and carry out sufficient lubrication. The rubber cap can be fitted on if it Another blade Fig. 8 Lever Slit of plunger Blade holder Machine oil Fig. 9 LeverEnglish

is pressed firmly onto the lever. At this time, make certain that there exists no clearance between the blade holder and the rubber cap, and furthermore ensure that the saw- blade-installed area can function smoothly. CAUTION: Do not use any saw blade with a worn-out blade hole. Otherwise, the saw blade can come off, resulting in personal injury. (Fig. 11)

8. Adjusting the base

This unit employs a mechanism that can adjust the base mounting position in three stages without the use of a wrench or other tools. (1) Press a pushbutton. When you do this, a base lever will jump out to prepare the base for adjustment (Fig. 12) (2) Push up the base tip and jog the base back and forth. (Fig. 13) (3) You can adjust the base position in three stages. Move the base at an interval of about 15 mm, find the position where the base hooks, and press in the base lever with your fingers. The base is secured when you hear the clicking sound. (Fig. 14)

9. Adjusting the blade reciprocating

speed This unit has a built-in electronic control circuit that makes it possible to adjust the variable speed of the saw blade either both by pulling a switching trigger or turning a dial. (Fig. 15) Blade hole Blade Fig. 11 Push button Base lever Fig. 12 Base Fig. 13 Graduation Switch trigger Dial Fig. 15 Lever Rubber cap Fig. 10 Base lever Fig. 14English

(1) If you pull the trigger further in, the speed of the blade accelerates. Begin cutting at a low speed to ensure the accuracy of your target cut position. Once you’ve obtained a sufficient cutting depth, increase the cutting speed. (2) On the dial scale, “5” is the maximum speed and “1” the minimum. The high speed is generally suitable for soft materials such as wood, and the low speed is suitable for hard materials such as metal. We recommend that you use the following as a rough guide in selecting the suitable speed for the materials you are cutting. CAUTION: 䡬 When cutting at low speed (scale of 1 – 2), never cut a wooden board more than 25/64" (10 mm) thick or a mild steel plate more than 5/64" (2 mm) thick. The load on the motor can result in overheating and damage. 䡬 Although this unit employs a powerful motor, prolonged use at a low speed will increase the load unduly and may lead to overheating. Properly adjust the saw blade to allow steady, smooth cutting operation, avoiding any unreasonable use such as sudden stops during cutting operation.

Adjusting the swing cutting operation Two cutting systems can be selected with this unit. The first is straight cutting, in which the saw blade is moved linearly, and the second is the swing cutting, in which the saw blade is swung like a pendulum. (Fig. 16, Fig. 17) (1) Straight cutting You can perform straight cutting by setting the change lever widthwise. Straight cutting should normally be performed when cutting hard materials such as metal, etc. (Fig. 16) (2) Swing cutting You can perform swing cutting by setting the change lever lengthways. Swing cutting should normally be performed when cutting soft materials such as wood, etc. Swing cutting is efficient since the saw blade forcibly bites into the material. (Fig. 17) CAUTION: 䡬 Even for soft materials, you should perform straight cutting if you wish to make curved or clean cuts. 䡬 Dust and dirt accumulated on the change lever section can degrade the function of the change lever. Periodically clean the change lever section. Example of materials Recommended to be cut dial scale Mild steel pipes / cast-iron tubes / 2 – 4 L-shaped angle steel Wood / wood with nails driven in

Stainless steel 1 – 3 Aluminum / brass / copper 2 – 4 Plaster board 4 – 5 Plastic / fiber board 1 – 3 Change lever Straight cutting Fig. 16 Change lever Swing cutting Fig. 17English

RECIPROCATING SAW CAUTION: 䡬 Avoid carrying it plugged to the outlet with your finger on the switch. A sudden startup can result in an unexpected injury. 䡬 Be careful not to let sawdust, earth, moisture, etc., enter the inside of the machine through the plunger section during operation. If sawdust and the like accumulate in the plunger section, always clean it before use. 䡬 Do not remove the front cover (refer to Fig. 2). Hold firmly the front cover by hand to operate. But, do not extend your hand or finger beyond the flange (see Fig.18) of front cover to avoid an injury. 䡬 During use, press the base against the material while cutting. Vibration can damage the saw blade if the base is not pressed firmly against the workpiece. Furthermore, a tip of the saw blade can sometimes contact the inner wall of the pipe, damaging the saw blade. 䡬 Select a saw blade of the most appropriate length. Ideally, the length protruding from the base of the saw blade after subtracting the stroke should be larger than the material (see Fig. 18 and Fig. 19). If you cut a large pipe, large block of wood, etc., that exceeds the cutting capacity of a blade; there is a risk that the blade may contact with the inner wall of the pipe, wood, etc., resulting in damage. (Fig. 20, Fig. 21) 䡬 To maximize cutting efficiency for the materials you are using and working conditions, adjust the speed of the saw blade and the switching to swing cutting.

1. Cutting metallic materials

CAUTION: 䡬 Press the base firmly against the workpiece. 䡬 Never apply any unreasonable force to the saw blade when cutting. Doing so can easily break the blade. Stroke Flange of front cover Front cover Fig. 18 Stroke Fig. 19 Fig. 21 Fig. 20English

(1) Fasten a workpiece firmly before operation. (Fig.22) (2) When cutting metallic materials, use proper machine oil (turbine oil, etc.). When not using liquid machine oil, apply grease over the workpiece. CAUTION: The service life of the saw blade will be drastically shortened if you don’t use machine oil. (3) Use the dial to adjust the speed of the saw blade to suit your working conditions and materials. (4) You can cut smoothly if you set the change lever position to straight cutting (Fig. 16).

(1) When cutting lumber, make sure that the workpiece is fastened firmly before beginning. (Fig. 23) (2) You can cut efficiently if the speed of the saw blade is set to dial scale “5”. (3) You can cut efficiently if the change lever position is set to swing cutting (Fig. 17). Alternatively, you can cut cleanly if the change lever position is set to straight cutting (Fig. 16). CAUTION: Never apply any unreasonable force to the saw blade when cutting. Also remember to press the base against the lumber firmly.

3. Sawing curved lines

We recommend that you use the BIMETAL blade mentioned in Page 18 for the saw blade since it is tough and hardly breaks. CAUTION: Delay the feed speed when cutting the material into small circular arcs. An unreasonably fast feed may break the blade.

With this tool, you can perform pocket cutting on plywood panels and thin board materials. You can carry out pocket cutting quite easily with the saw blade installed in reverse as illustrated in Fig. 25, Fig. 27, and Fig. 29. Use the saw blade that is as short and thick as possible. We recommend for this purpose that you use BI-METAL Blade No. 132 mentioned in Page 18. Be sure to use caution during the cutting operation and observe the following procedures. (1) Press the lower part (or the upper part) of the base against the material. Pull the switch trigger while keeping the tip of the saw blade apart from the material. (Fig. 24, Fig. 25) Fig. 22 Fig. 23English

(2) Raise the handle slowly and cut in with the saw blade little by little. (Fig. 26, Fig. 27) (3) Hold the body firmly until the saw blade completely cuts into the material. (Fig. 28, Fig. 29) CAUTION: 䡬 Avoid plunge cutting for metallic materials. This can easily damage the blade. 䡬 Never pull the switch trigger while the tip of the saw blade tip is pressed against the material. If you do so, the blade can easily be damaged when it collides with the material. 䡬 Make absolutely sure that you cut slowly while holding the body firmly. If you apply any unreasonable force to the saw blade during the cutting operation, the blade can easily be damaged. Fig. 26 Fig. 27 Fig. 24 Fig. 25 Fig. 28 Fig. 29English

1. Inspecting the blade

Continued use of a dull or damaged blade will result in reduced cutting efficiency and may cause overloading of the motor. Replace the blade with a new one as soon as excessive abrasion is noted.

2. Inspecting the mounting screws

Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loosened, retighten them immediately.

WARNING: Using this reciprocating

saw with loosen screws is extremely dangerous.

3. Maintenance of the motor

The motor unit winding is the very “heart“ of the power tool. Exercise due care to ensure the winding does noto become damaged and/or wet with oil or water.

4. Inspecting the carbon brushes (Fig. 30)

The Motor employs carbon brushes which are consumable parts. When they become worn to or near the “wear limit”, it could result in motor trouble. When an auto-stop carbon brush is equipped, the motor will stop automatically. At that time, replace both carbon brushes with new ones which have the same carbon brush Numbers shown in the figure. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.

5. Replacing carbon brushes

Disassemble the brush caps with a slotted-head screwdriver. The carbon brushes can then be easily removed.

6. Service and repairs

All quality power tools will eventually require servicing or replacement of parts because of wear from normal use. To assure that only authorized replacement parts will be used, all service and repairs must be performed by a HITACHI AUTHORIZED SERVICE CENTER, ONLY.
