SAFETY
GENERAL SAFETY RULES – FOR ALL BATTERY OPERATED TOOLS
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.Work Area
(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)A battery operated tool with integral batteries or a separate battery pack must be recharged only with the specified charger for the battery.
A charger that may be suitable for one type of battery may create a risk of fire when used with another battery.
(2)Use battery operated tool only with specifically designed battery pack.
Use of any other batteries may create a risk of fire.
3.Personal Safety
(1)Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired 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 position before inserting battery.
Carrying tools with your finger on the switch or inserting the battery pack into a tool 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 enable 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.
4
English
4.Tool Use and Care
(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 battery pack from tool or place the switch in the locked or off position before making any adjustments, changing accessories, or storing the tools. 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)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 sparks, burns, or a fire.
(7)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.
(8)Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tools operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.
(9)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 on another tool.
5.Service
(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.
WARNING:
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known [to the State of California] 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.

How to make the batteries perform longer.
Recharge the batteries before they become completely exhausted.
When you feel that the power of the tool becomes weaker, stop using the tool and recharge its battery. If you continue to use the tool and exhaust the electric current, the battery may be damaged and its life will become shorter.
Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and the battery life will be shortened. Leave the battery and recharge it after it has cooled for a while.
CAUTION:
●When the battery charger has been continuosly used, the battery charger will heated, thus constituting the cause of the failures. Once the charging has been completed, give 15 minutes rest until the next charging.
●If the battery is rechraged when it is warm due to battery use or exposure to sunlight, the pilot lamp may light in green.
The battery will not be recharged. In such a case, let the battery cool before charging.
●When the pilot lamp flickers in red (at 0.2 second intervals), check for and take out any foreign objects in the charger’s battery installation hole. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your authorized Service Center.
BEFORE USE
Check the work area to make sure that it is clear of debris and clutter.
Clear the area of unnecessary personnel. Ensure that lighting and ventilation is adequate.

HOW TO USE THE CORDLESS RECIPROCATING SAW
CAUTION:
Avoid carrying it with your finger on the switch. A sudden startup can result in an unexpected injury.
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.
Do not remove the front cover (refer to Fig. 5).
Be sure to hold the body from the top of the front cover.
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.
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. 17 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. 18, Fig. 20)
To extend the lifetime, the lithium-ion battery equips with the protection function to stop the output. Therefore, if the tool is overloaded, the motor may stop. However, this is not the trouble but the result of protection function. In this case, release the switch of tool and eliminate the causes of overloading.
1. Switch operation
(1)Lock-off button
The tool is equipped with a lock-off button. To acivate the trigger lock, move the button to the right positon. Move the button to the left to operate the tool. (Fig. 21, Fig. 22)

(2)Trigger switch
This tool is equipped with a variable speed controlled trigger switch. The tool can be turned "ON" or "OFF" by squeezing or releasing the trigger. The blade plunger stroke rate can be adjusted from the minimum to maximum nameplate stroke rate by the pressure you apply to the trigger. Apply more pressure to increase the speed and release pressure to decrease speed.
2.Cutting metallic materials
CAUTION:
Press the base firmly against the workpiece.
Never apply any unreasonable force to the saw blade when cutting. Doing so can easily break the blade.
The motor can be locked sometimes, depending on the combination of the material to be cut and the blade. Whenever the motor gets locked, switch it off immediately.
(1)Fasten a workpiece firmly before operation. (Fig. 23)
(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.Cutting lumber
When cutting lumber, make sure that the workpiece is fastened firmly before beginning. (Fig. 24)
CAUTION: Never apply any unreasonable force to the saw blade when cutting. Also remember to press the base against the lumber firmly.
4.Sawing curved lines
We recommend that you use the BIMETAL blade mentioned in Page 26 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.
5.Plunge cutting
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. 26, Fig. 28, and Fig. 30. 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 26. 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. 25, Fig. 26)
(2) Raise the handle slowly and cut in with the saw blade little by little. (Fig. 27, Fig. 28)
(3) Hold the body firmly until the saw blade completely cuts into the material. (Fig. 29, Fig. 30)
CAUTION:
Avoid plunge cutting for metallic materials. This can easily damage the blade.
Never pull the switch trigger while the tip of the saw blade is pressed against the material. If you do so, the blade can easily be damaged when it collides with the material.
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.

MAINTENANCE AND INSPECTION
WARNING: Be sure to turned off the switch and remove the battery before maintenance and inspection.
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 screws
Regularly inspect all screws and ensure that they are properly tightened. Should any of the screws be loosened, retighten them immediately.
WARNING: Using this Cordless Reciprocating Saw with loosened 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 not become damaged and/or wet with oil or water.
4.Inspecting the carbon brushes (Fig. 31)
The motor employs carbon brushes which are consumable parts. Since and excessively worn carbon brush can result in motor trouble, replace the carbon brush with new ones when it becomes worn to or near the “wear limit”. In addition, always keep carbon brushes clean and ensure that they slide
freely within the brush holders.
NOTE:
When replacing the carbon brush with a new one, be sure to use the Hitachi Carbon Brush Code No. 999058.
5.Replacing carbon brushes
Take out the carbon brush by first removing the brush cap and then hooking the protrusion of the carbon brush with a slotted-head screw driver, etc., as shown in Fig. 32, Fig. 33.
When installing the carbon brush, choose the direction so that the nail of the carbon brush (Fig. 32) agrees with the contact portion outside the brush tube (Fig. 34). Then push it in with a finger.
Lastly, install the brush cap.
