USER MANUAL CR18DMR HiKOKI

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. 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 tools 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. 0000BookCR18DMRDLWE.indb70000BookCR18DMRDLWE.indb7 2017/12/0813:38:012017/12/0813:38:018 English

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 qualifi ed repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained. PRECAUTION Keep children and infi rm persons away. When not in use, tools should be stored out of reach of children and infi rm persons.

1. Always charge the battery at a temperature of 10 –

40°C. A temperature of less than 10°C will result in over charging which is dangerous. The battery cannot be charged at a temperature higher than 40°C. The most suitable temperature for charging is that of 20 – 25°C.

NOTE: When standby for cooling battery, UC18YRL cools the overheated battery by cooling fan. (2) Regarding the temperatures of the rechargeable battery The temperatures for rechargeable batteries are as shown in the table below, and batteries that have become hot should be cooled for a while before being recharged. Table 2 Recharging ranges of batteries Charger

4. Disconnect the charger’s power cord from the

5. Hold the charger fi rmly and pull out the battery

NOTE Be sure to pull out the battery from the charger after use, and then keep it. CAUTION ○ 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 up green. In such a case, fi rst let the battery cool, then start charging. ○ When the pilot lamp fl ikers in red quickly (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. ○ Since the built-in micro computer takes about 3 seconds to confi rm that the battery being charged with UC24YFA and UC18YRL are 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. 〈UC18YG〉 Before using the power tool, charge the battery as follows.

1. Connect the charger power cord to the receptacle

Connecting the power cord will turn on the charger.

2. Insert the battery into the charger

Insert the battery fi rmly while observing its direction, until it contacts the bottom of the charger (the pilot lamp lights up). CAUTION If the pilot lamp does not light up, pull out the power cord from the receptacle and check the battery mounting condition. About 50 minutes is required to fully charge the battery at a temperature of about 20°C. The pilot lamp goes off to indicate that the battery is fully charged. The battery charging time becomes longer when a temperature is low or the voltage of the power source is too low. When the pilot lamp does not go off even if more than 120 minutes have elapsed after starting of the charging, stop the charging and contact your HiKOKI AUTHORIZED SERVICE CENTER. CAUTION If the battery is heated due to direct sunlight, etc., just after operation, the charger pilot lamp may not light up. At that time, cool the battery fi rst, then start charging.

3. Disconnect the charger power cord from the

4. Hold the charger tight and pull out the battery

Regarding electric discharge in case of new batteries, etc. As the internal chemical substance of new batteries and batteries that have not been used for an extended period is not activated, the electric discharge might be low when using them the fi rst and second time. This is a temporary phenomenon, and normal time required for recharging will be restored by recharging the batteries 2 – 3 times. 0000BookCR18DMRDLWE.indb110000BookCR18DMRDLWE.indb11 2017/12/0813:38:022017/12/0813:38:0212 English How to make the batteries perform longer (1) 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. (2) 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.

1. 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 remove the battery (Fig. 6). CAUTION Be absolutely sure to keep the switch turned off and the battery removed to prevent any accident. (2) Push the lever in the direction of the arrow mark shown in Fig. 7 marked on the lever (Fig. 7). (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. 8, Fig. 9). (4) When you release the lever, the spring force will return the lever to the correct position automatically (Fig. 10). (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. 11). 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.

2. 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 remove the battery (Fig. 6). CAUTION Be absolutely sure to keep the switch turned off and the battery removed to prevent any accident. (2) After you have pushed the lever in the direction of the arrow mark shown in Fig. 7 and secured it, 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. 12).

MAINTENANCE AND INSPECTION OF SAW BLADE

MOUNT (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. 13, carry out lubrication around the blade holder on a periodic basis by use of cutting fl uid, 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. 14 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 suffi cient lubrication. The rubber cap can be fi tted on if it is pressed fi rmly 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. 15).

Loosen the set screw and move the base forward, as shown in Fig. 16, Fig. 17. Tighten the set screw slightly, ensure the base does not move back and forth, and fi rmly tighten the set screw. Ensure that the base does not contact the blade.

4. Confi rm that the battery is mounted correctly

CAUTION ○ Do not carry tools with your fi nger 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 (refer to Fig. 6). ○ Do not remove the front cover. Be sure to hold the body from the top of the front cover (refer to Fig. 6). ○ During use, press the base against the material while cutting. Vibration can damage the saw blade if the base is not pressed fi rmly against the workpiece. Furthermore, a tip of the saw blade can sometimes contact the inner wall of the pipe, damaging the saw blade. 0000BookCR18DMRDLWE.indb120000BookCR18DMRDLWE.indb12 2017/12/0813:38:022017/12/0813:38:0213 English ○ Select a saw blade of the most appropriate length. Ideally, the length protruding from the base of the saw blade after subtracting the stroke quantity should be larger than the material (see Fig. 19 and Fig. 21). 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. 22).

(1) Lock-off button The tool is equipped with a lock-off button. To activate the trigger lock, move the button to the right position. Move the button to the left to operate the tool (Fig. 18). Always lock the switch when carrying or storing the tool eliminate unintentional starting. (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 fi rmly 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 fi rmly 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.

When cutting lumber, make sure that the workpiece is fastened fi rmly 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 fi rmly.

4. Sawing curved lines

We recommend that you use the BI-METAL blade mentioned in Table 4 (Page 14) 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 plunge 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 14, Table 4. 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 fi rmly 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 fi rmly. If you apply any unreasonable force to the saw blade during the cutting operation, the blade can easily be damaged. NOTE The use of the battery EB1826HL and EB1830HL in a cold condition (below 0 degree Centigrade) can sometimes result in the weakened cutting torque and reduced amount of work. This, however, is a temporary phenomenon, and returns to normal when the battery warms up.

To ensure maximum operating effi ciency and results, it is very important to select the appropriate blade best suited to the type and thickness of the material to be cut. NOTE ○ Dimensions of the workpiece mentioned in the table represent the dimensions when the mounting position of the base is set nearest to the body of the Cordless Reciprocating Saw. Caution must be exercised since dimensions of the workpiece will become smaller if the base is mounted far away from the body of the Cordless Reciprocating Saw.

CAUTION 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 effi ciency 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 loose, retighten them immediately. Failure to do so could result in serious hazard.

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 HiKOKI Carbon Brush Code No.

5. Replacing carbon brushes

Take out the carbon brush by fi rst removing the brush cap and then hooking the protrusion of the carbon brush with a fl at head screw driver, etc., as shown in Fig. 33. When installing the carbon brush, choose the direction so that the nail of the carbon brush agrees with the contact portion outside the brush tube. Then push it in with a fi nger as illustrated in Fig. 34. Lastly, install the brush cap. CAUTION Be absolutely sure to insert the nail of the carbon brush into the contact portion outside the brush tube (You can insert whichever one of the two nails provided). Caution must be exercised since any error in this operation can result in the deformed nail of the carbon brush and may cause motor trouble at an early stage.

6. Cleaning of the outside

When the Cordless Reciprocating Saw is stained, wipe with a soft dry cloth or a cloth moistened with soapy water. Do not use chloric solvents, gasoline or paint thinner, as they melt plastics.

Store the Cordless Reciprocating Saw in a place in which the temperature is less than 40°C, and out of reach of children.
