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.

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.

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. 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. 000BookCB18DBLUS.indb3000BookCB18DBLUS.indb3 2016/11/1716:50:002016/11/1716:50:004 English 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.

5) Battery tool use and care

a) Recharge only with the charger specifi ed by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fi re when used with another battery pack. b) Use power tools only with specifi cally designated battery packs. Use of any other battery packs may create a risk of injury and fi re. 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 fi re. d) Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, fl ush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

a) Have your power tool serviced by a quali fi ed repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained. –WARNING– To reduce the risk of injury, user must read instruction manual. 000BookCB18DBLUS.indb4000BookCB18DBLUS.indb4 2016/11/1716:50:002016/11/1716:50:005 English WARNING Some dust created by power cutting, 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:

If the battery is charged while it is heated because it has been left for a long time in a location subject to direct sunlight or because the battery has just been used, the pilot lamp of the charger lights for 1 second, does not light for

0.5 seconds (off for 0.5 seconds). In such a case,

fi rst let the battery cool, then start charging.

When the pilot lamp fl ikers rapidly in red (at 0.2–second intervals), check for and take out any foreign objects in the charger's battery connector. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your authorized Service Center.

Since the built-in micro computer takes about 3 seconds to confi rm that the battery being charged with charger is taken out, wait for a minimum of 3 seconds before reinserting it to continue charging. If the battery is reinserted within 3 seconds, the battery may not be properly charged.

If the pilot lamp does not blink in red (every second) even though the charger cord is connected to the power, it indicates that the protection circuit of the charger may be activated. (2) Regarding the temperature of the rechargeable battery. The temperatures for rechargeable batteries are as shown in the Table 3, and batteries that have become hot should be cooled for a while before being recharged. Table 3 Recharging ranges of batteries Rechargeable battery Temperatures at which the battery can be recharged BSL1850 32°F – 104°F (0°C – 40°C) (3) Regarding recharging time (At 68°F (20°C)) Table 4 Charging time (At 20°C) Charger Battery UC18YFSL BSL1850 Approx. 75 min. NOTE The charging time may vary according to temperature and power source voltage.

4. Disconnect battery charger from the receptacle.

CAUTION Do not pull the plug out of the receptacle by pulling on the cord. Make sure to grasp the plug when removing from receptacle to avoid damaging cord.

5. Remove the battery from the battery charger.

Supporting the battery charger with hand, pull out the battery from the battery charger. NOTE After operation, pull out batteries from the charger fi rst, and then keep the batteries properly. 000BookCB18DBLUS.indb14000BookCB18DBLUS.indb14 2016/11/1716:50:022016/11/1716:50:0215 English Remove the cord or plug from the power and then connect it again after 30 seconds or so. If this does not cause the pilot lamp to blink in red (every second), please take the charger to the Hitachi Authorized Service Center.

1. Preparing and checking the work environment

Make sure that the work site meets all the conditions laid forth in the precautions.

2. Installing the side handle

Be sure to install the side handle and use both hands while operating. Failure to do so may result in injury. (See Fig. 6) Side Handle

3. Checking the battery

Make sure that the battery is installed fi rmly. If it is at all loose it could come off and cause an accident.

To save the battery power consumption, the remaining battery indicator lamp lights while pressing the remaining battery indicator switch.

Unless the power is switched on after installing the battery to the unit, remaining battery indicator lamp will not light up when the remaining battery indicator switch is pressed.

8. Adjusting operating speed (Fig. 11)

CAUTION Use the band saw blade circumferential speed setting dial to select the circumferential speed best suited for the workpiece. Using a band saw blade circumferential speed unsuited to cut a workpiece will not only negatively aff ect cutting precision, but can also cause damage to the band saw blade. This unit is equipped with an electronic control circuit that allows the circumferential speed of the band saw blade to be freely adjusted. Prior to operation, use the band saw blade circumferential speed setting dial to set a mode that suits the properties, thickness and task conditions of the workpiece being cut.

In Standard Mode, the circumferential speed or the band saw blade can be freely set from 1 to 5 on the dial. On the dial, 1 is the lowest speed and 5 is the highest speed. In Standard Mode, the circumferential speed that is set with the dial is maintained even when the load changes.

In AUTO Mode (“A” on the dial), noise can be reduced and the duration of operation can be extended by lowing the circumferential speed when there is no load. In AUTO Mode, if a load is applied during operation, the circumferential speed is automatically increased. (Equivalent of 5 on the dial) Additionally, if the load becomes lighter after cutting is completed, the circumferential speed is automatically decreased, reducing power consumption when there is no load. NOTE

Using a soft cloth, wipe off any foreign matter that has adhered to the lens of the LED light, being careful not to scratch the lens. Scratches on the LED light may reduce the brightness of the light.

When cleaning the lens of the LED light, do not wipe with gasoline, paint thinner, etc. Doing so will damage the lens.

Verify that there are no nicks, cracks, or other abnormalities on the band saw blade before installing it.

Wipe off any oil or grime adhering to the band saw blade before installing it on the blade pulleys. Additionally, wipe off any shavings or grime adhering to the blade pulley rubbers. If a band saw blade that has oil or grime adhering to it is installed on the blade pulleys, the band saw blade may slip or come loose.

When installing the band saw blade, do not twist or bend its joint. Doing so may damage the band saw blade. CAUTION: on lithium-ion battery 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. CAUTION

When switching on the tool, make sure the band saw blade is not in contact with the workpiece. Failure to do so may result in injury.

For cutting effi ciency, switch the band saw blade speed according to operating conditions and workpiece to be cut.

Do not apply any unnecessary pressure when operating the tool. Doing so may damage the band saw blade.

After use, be sure not to place the tool near chips before it comes to a full stop as the tool may suck in those particles. CUTTING OPERATION WARNING

Be absolutely sure to keep the switch turned off and the battery removed to prevent any accident.

During operation, do not place your face or hands near the application tool of the unit.

Select a band saw blade (the band saw blade’s teeth/ inch) and a band saw blade operating speed that is suitable for properties and thickness of the workpiece to be cut. 000BookCB18DBLUS.indb19000BookCB18DBLUS.indb19 2016/11/1716:50:032016/11/1716:50:0320 English

When using a new band saw blade, be sure to set the band saw blade operating speed setting dial to “1” and perform 1–2 warm-up cuts with a light cutting load (while pulling slightly upward on the product) on an object with an outer diameter of 3/4" or less such as cylindrical rod (carbon steel). Failure to perform warm-up cuts may result in nicks on the blade edge and decreased cutting precision.

Do not cut thermoplastic material. It can melt from cutting friction heat which can result in the band saw blade becoming wedged in the material, causing the motor to lock up.

Do not cut hard materials such as hardened steel.

If there is a gap between the guide plate and the workpiece, the piece may erratically shift position and cause breakage to the band saw blade.

Do not apply excessive loads to the band saw blade.

When the workpiece is thin (0.08" thick or less), cut with the piece slightly raised up.

About continuous operation This tool is equipped with a temperature protection circuit for safeguarding the motor as well as the electronic motor drive control components. If the tool is operated continuously, the temperature of the unit may rise and activate the temperature protection circuit, automatically stopping operation. If this happens, allow the machine to suffi ciently cool. Once the temperature has decreased, the tool is ready to be used again. In the event the storage battery is changed during continuous operation, allow the cordless tool to rest for about 15 minutes before resuming use. If operation is resumed soon after the battery is changed, the temperatures of the motor, switch, etc. will become high and may result in malfunction or damage.

About holding the unit and applying force Hold the tool securely with both hands. When holding the unit, make sure the band saw blade is perpendicular to the workpiece. Additionally, there is no need to push the unit with any excessive force. Be aware that applying any excessive prying or pressing force to the tool may result in the unit’s malfunction or damage. For stable cut, always keep at least two teeth in the cut. Select the proper cutting position for your workpiece by referring to the fi gure.

1. Press the workpiece against the guide plate (Fig. 14)

Press the workpiece against the guide plate in a position where there is no contact with the band saw blade.

2. Press the switch and cut (Fig. 14)

When the revolutions are stable, avoid any sudden impact to the band saw and gently bring the band saw to the workpiece to cut. When completing a cut, hold the tool fi rmly, so it will not fall against the workpiece. Guide plate Workpiece Band saw blade

Be sure to tunred off the switch and pull out the battery. Be sure to wear gloves when handling the band saw blade.

1. Replacing the band saw blade (Fig. 12, 13)

If the band saw blade becomes dull, it can result in overburdening the motor and the various parts of the tool as well as decrease effi ciency. Do not delay in replacing the band saw blade.

2. Blade pulley rubbers inspection (Fig. 15)

The blade pulley rubbers are installed on the outer circumferences of the blade pulleys (2 places). (Fitted type) When replacing the band saw blade, inspect the blade pulley rubbers for sagging or damage. If there is sagging or damage, request a replacement from Hitachi Authorized Service Center, as it may result in the band saw blade running unstable or coming loose. NOTE Periodically remove any shavings, etc. that has adhered to the blade pulley rubbers. Failure to do so may result in slippage of the band saw blade and/or injury.
