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. 000BookCS3630DA.indb6000BookCS3630DA.indb6 2019/07/2917:49:362019/07/2917:49:367 English 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 toolsʼ 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 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.

CHAIN SAW SAFETY WARNINGS

1. Keep all parts of the body away from the saw chain when

the chain saw is operating. Before you start the chain saw, make sure the saw chain is not contacting anything. A moment of inattention while operating chain saws may cause entanglement of your clothing or body with the saw chain.

2. Always hold the chain saw with your right hand on the rear

handle and your left hand on the front handle. Holding the chain saw with a reversed hand confi guration increases the risk of personal injury and should never be done. 000BookCS3630DA.indb7000BookCS3630DA.indb7 2019/07/2917:49:372019/07/2917:49:378 English

3. Hold the power tool by insulated gripping surfaces only,

because the saw chain may contact hidden wiring. Saw chains contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.

4. Wear safety glasses and hearing protection. Further

protective equipment for head, hands, legs and feet is recommended. Adequate protective clothing will reduce personal injury by fl ying debris or accidental contact with the saw chain.

5. Do not operate a chain saw in a tree. Operation of a

chain saw while up in a tree may result in personal injury.

6. Always keep proper footing and operate the chain saw

only when standing on fi xed, secure and level surface. Slippery or unstable surfaces such as ladders may cause a loss of balance or control of the chain saw.

7. When cutting a limb that is under tension be alert for

spring back. When the tension in the wood fi bres is released the spring loaded limb may strike the operator and/or throw the chain saw out of control.

8. Use extreme caution when cutting brush and saplings.

The slender material may catch the saw chain and be whipped toward you or pull you off balance.

9. Carry the chain saw by the front handle with the chain saw

switched off and away from your body. When transporting or storing the chain saw always fi t the guide bar cover. Proper handling of the chain saw will reduce the likelihood of accidental contact with the moving saw chain.

10. Follow instructions for lubricating, chain tensioning

and changing accessories. Improperly tensioned or lubricated chain may either break or increase the chance for kickback.

11. Keep handles dry, clean, and free from oil and grease.

Greasy, oily handles are slippery causing loss of control.

12. Cut wood only. Do not use chain saw for purposes not

intended. For example: do not use chain saw for cutting plastic, masonry or non-wood building materials. Use of the chain saw for operations diff erent than intended could result in a hazardous situation. Causes and operator prevention of kickback: (Fig. 2) Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a sudden reverse reaction, kicking the guide bar up and back towards the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator. Either of these reactions may cause you to lose control of the saw which could result in serious personal injury. Do not rely exclusively upon the safety devices built into your saw. As a chain saw user, you should take several steps to keep your cutting jobs free from accident or injury. Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below: ○ Maintain a fi rm grip, with thumbs and fi ngers encircling the chain saw handles, with both hands on the saw and position your body and arm to allow you to resist kickback forces. Kickback forces can be controlled by the operator, if proper precautions are taken. Do not let go of the chain saw. ○ Do not overreach and do not cut above shoulder height. This helps prevent unintended tip contact and enables better control of the chain saw in unexpected situations. ○ Only use replacement bars and chains specifi ed by the manufacturer. Incorrect replacement bars and chains may cause chain breakage and/or kickback. ○ Follow the manufacturer’s sharpening and maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kickback.

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. 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. 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. 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 charge indicator lamp of the charger lights for 0.3 seconds, does not light for 0.3 seconds (off for

0.3 seconds). In such a case, fi rst let the battery cool,

then start charging. ○ When the charge indicator lamp fl ickers (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 UC18YSL3 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.

INSTALLING (REPLACING) SAW

CHAIN WARNING ○ To prevent accidents, always switch the unit off , and remove the storage battery. ○ Don't use the saw chain or the guide bar other than those specifi ed in “SPECIFICATIONS”. CAUTION Wear gloves and be careful to avoid injury with the saw chain. NOTE ○ When removing the saw chain, remove sawdust from the oil spout, oil hole, and guide bar groove. If sawdust accumulates, this may cause the unit to fail. ○ Use the correct type of saw chain in accordance with the specifi cations. If you install the wrong type of guide bar, the saw chain may come off and injury may occur.

4. Installing the side cover

1 Align the bolt with the bolt hole (Fig. 10) 2 Adjust the tension dial of the side cover so that the chain tensioner boss is inserted into the guide bar chain tensioner hole, and attach the side cover. (Fig. 11) 3 Rotate the knob once to temporarily fi x it. (Fig. 12)

5. Adjusting the saw chain tension (Fig. 13)

○ While lifting the guide bar tip, turn the tension dial to adjust the saw chain tension. ○ Turn the tension dial to the right to increase the saw chain tension, and to the left to decrease it.

6. Checking the saw chain tension (Fig. 14)

Adjust the saw chain tension so that the gap between the saw chain drive link and the guide bar is 0.5 to 1 mm when you lift the saw chain slightly near the center of the guide bar.

7. Securing the knob (Fig. 15)

1 When adjustment is complete, lift up the guide bar, and fully tighten the knob. 2 Make sure the bolt is fi rmly tightened. WARNING After adjusting the saw chain tension, ensure the knob is fully tightened. If it is loose, injury may occur.

Prior to use, make the following inspection and preparation. WARNING ○ To prevent accidents, always perform steps 1 to 4 ensuring the storage battery is removed from the body. ○ Do not secure the lock-off button while it is pressed. If the switch is accidentally engaged, the unit may unexpectedly start and injury may occur.

1. Ensuring the switch is off

○ If you insert the storage battery without knowing whether the switch is engaged, the unit may unexpectedly start, which may result in an accident. ○ When the switch is engaged while pressing the lock- off button, the unit switches on, and when the switch is released, the unit switches off .

2. Checking the saw chain tension

○ If the saw chain tension is incorrect, there is a risk of damage to the saw chain or guide bar and malfunction. Referring to steps 5 to 7 “Installing (replacing) saw chain,” ensure an appropriate tension is set. ○ While the saw chain is still new, it is particularly stretchy, so periodically check the tension and adjust as required. ○ Also check the knob is securely tightened.

3. Checking operation of chain brake (Fig. 16)

WARNING ○ Although the chain brake is an emergency stop device, this is not completely reliable. Operate carefully to avoid the risk of kickback. ○ The chain brake is intended for use in emergencies and when starting up. Do not use it indiscriminately. ○ To avoid impaired movement of the chain brake due to buildup of sawdust etc., clean regularly. ○ The chain brake is an important component to ensure safe use. If you have any concern regarding the brake operation, request repair from your HiKOKI Authorized Service Center. The chain brake is an emergency stop device that stops the saw chain when the unit is subject to kickback etc., to reduce risk. (Refer to “Causes and operator prevention of kickback.”) When activating the chain brake by pushing the brake lever forward, the saw chain stops moving. If you pull the brake lever toward you, the brake is released. When confi rming the operation of the chain brake, always switch the unit off , remove the battery, activate the brake lever and pull the saw chain by hand. If the saw chain does not move, this means the chain brake is activated. NOTE Always wear thick gloves for this task. Since the saw chain blade is very sharp, pulling it hard risks injuring your fi ngers.

4. Checking the chain oil

○ This unit is delivered without chain oil inside. Ensure the oil tank is fi lled with the chain oil provided before use. (Fig. 17) ○ Periodically check the oil sight glass during work and replenish oil as required. ○ When you press the light switch on the switch panel, an LED light turns on and the internal light improves visibility. (Fig. 18) (Check this in step 6.) ○ If the chain oil supplied runs out, use HiKOKI chain oil sold separately or equivalent chain oil on the market. ○ The chain oil lubricates automatically. The discharge rate for auto lubrication is factory preset to the maximum. To reduce the discharge rate, turn the oil pump adjuster on the rear of the body clockwise. (Fig. 19) NOTE ○ The oil tank capacity is about 80 ml. Even if overfi lled, excess oil will escape from the overfl ow spout. ○ We recommend that you stock up with chain oil. If you continue working without chain oil, the saw chain may burn through, or the motor may fail. ○ Be careful to avoid dust or other foreign matter from entering the oil tank. If dust and other foreign matter enter the oil tank, the unit may fail. ○ Chain oil left in the tank may leak due to the structure of this unit. Although this does not indicate a malfunction, it may soil the storage location, so be careful. When storing, empty the oil from the oil tank, and place an item under the main body which can absorb any leaks.

5. Installing the storage battery (Fig. 4)

As shown in Fig. 4, push fi rmly until it clicks into place. CAUTION Securely attach the storage battery. If the storage battery is not securely attached, it may come off and injury may occur.

6. Checking if the LED light works (Fig. 18)

○ When you press the light switch, the LED light turns on and when released, the light goes out. ○ The LED light illuminates the cutting edge section. ○ It lights up the inside of the oil sight glass to facilitate checks of the remaining oil level. NOTE If the light is dirty, carefully wipe with a soft cloth etc., to avoid damaging it. If the light is damaged, this will reduce the brightness.

7. Checking brake is engaged

○ When the switch is engaged while pressing the lock- off button, the unit switches on, and when the switch is released, the unit switches off . ○ In addition, 1 to 3 seconds after releasing the switch, the unit applies a brake to stop the rotation of the saw chain. ○ Before using, check to ensure brake is engaged. CAUTION Be careful of the repulsive force when the brake is engaged. If you drop the unit, injury may occur. 000BookCS3630DA.indb14000BookCS3630DA.indb14 2019/07/2917:49:372019/07/2917:49:3715 English

8. Checking chain oil discharge (Figs. 19, 20)

○ When switching the unit on, chain oil automatically lubricates the saw chain and guide bar. ○ If oil does not seem to emerge 2 to 3 minutes after the unit starts, check if any sawdust has accumulated around the oil spout. (Refer to “Cleaning the chain oil spout.”) (Refer to “Checking the chain oil.”) Switch operation When the switch is engaged while pressing the lock-off button, the saw chain rotates. (Fig. 21) Unless the lock-off button is pressed, the switch cannot be engaged. After the switch is engaged, the saw chain continues rotating as long as it is pressed down. In addition, the LED light remains lit up. When the switch is released, a brake is applied to stop the saw chain rotation. WARNING Do not secure the lock-off button while it is pressed. If the switch is accidentally engaged, the unit may unexpectedly start and injury may occur. Using the hook Pull out the hook from the unit, to which a rope etc. can be tied to suspend the unit. (Fig. 23) WARNING When using the hook, ensure the unit is securely suspended to avoid the risk of falling. If the unit falls, an accident may occur.

REMAINING BATTERY INDICATOR

You can check the battery’s remaining capacity by pressing the remaining battery indicator switch to light the indicator lamp. (Fig. 22, Table 3) The indicator will shut off approximately 3 seconds after the remaining battery indicator switch is pressed. It is best to use the remaining battery indicator as a guide since there are slight diff erences such as ambient temperature and the condition of the battery. Also, the remaining battery indicator may vary from those equipped to a tool or charger. Table 3 State of lamp Battery Remaining Power Lights ; The battery remaining power is over 75%. Lights ; The battery remaining power is 50% – 75%. Lights ; The battery remaining power is 25% – 50%. Lights ; The battery remaining power is less than 25%. Blinks ; The battery remaining power is nearly empty. Recharge the battery soonest possible. Blinks ; Output suspended due to high temperature. Remove the battery from the tool and allow it to fully cool down. Blinks ; Output suspended due to failure or malfunction. The problem may be the battery so please contact your dealer. As the remaining battery indicator shows somewhat diff erently depending on ambient temperature and battery characteristics, read it as a reference. NOTE ○ Do not give a strong shock to the switch panel or break it. It may lead to a trouble. ○ To save the battery power consumption, the remaining battery indicator lamp lights while pressing the remaining battery indicator switch. CUTTING PROCEDURES WARNING ○ Prior to operation, ensure that chain brake works. ○ During use, grip the handle securely with both hands. ○ When cutting timber from the bottom, ensure the saw chain does not impact with the timber. If the unit is pushed back, injury may occur. ○ During work breaks or after work, always switch the unit off , and remove the storage battery from the main body. Always monitor the workplace and surrounding area, ensure there are no objects which could cause injuries, accidents or failure, and if any are present, remove them in advance. In particular, when establishing a foothold for working, ensure there is no instability or any object which could be tripped over. When felling standing trees, always pay careful attention to the direction in which the tree will fall or roll, and determine a safe evacuation area and escape route for yourself in advance. 1 Ensuring the unit is switched off If the storage battery is inserted while the switch is unknowingly engaged, the unit may unexpectedly start, which may result in an accident. 2 Installing the storage battery (Fig. 4) As shown in Fig. 4, push fi rmly until it clicks into place. 3 Engaging the switch Ensuring the saw chain is not in contact with the timber, engage the switch, and start cutting when the saw chain speed has increased. CAUTION ○ When switching the unit on, ensure the saw chain does not contact with material or anything else. ○ During use, be careful to ensure the saw chain does not contact with other material or object. In particular, when you have fi nished cutting, be careful to ensure it does not touch the ground. NOTE Refi ll the oil tank early to prevent the unit running out of oil.

1. General cutting procedures

(1) Switch ON the power while keeping the saw slightly away from the wood to be cut. Start sawing only after the unit has reached full speed. (2) When sawing a slender piece of wood, press the base section of the guide bar against the wood and saw downward as shown in Fig. 24. (3) When sawing a thick piece of wood, press the spike on the front section of the unit against the wood and cut it with a lever action while using the spike as a fulcrum as shown in Fig. 25. (4) When cutting wood horizontally, turn the unit body to the right so that the guide bar is below and hold the upper side of the front handle with your left hand. Hold the guide bar horizontally and place the spike that is on the front of the unit body on the lumbar. Using the spike as a fulcrum, cut into the wood by turning the rear handle to the right. (Fig. 26) (5) When cutting into wood from the bottom, touch the upper part of the guide bar to the wood lightly. (Fig. 27) 000BookCS3630DA.indb15000BookCS3630DA.indb15 2019/07/2917:49:372019/07/2917:49:3716 English (6) As well as carefully studying the handling instructions, ensure practical instruction in the operation of the chain saw prior to use, or at least practice working with the chain saw by cutting lengths of round timber on a sawing trestle. (7) When cutting logs or timbers which are not supported, support them properly by immobilizing them during cutting using a sawing trestle or other proper method. CAUTION ○ When cutting wood from the bottom, there is a danger that the unit body may be pushed back toward the user if the chain strongly impacts with the wood. ○ Do not cut all the way thorough the wood by starting from the bottom since there is the danger of the guide bar fl ying up out of control when the cut is fi nished. ○ Always prevent the operating chain saw from touching the ground or wire fences.

(1) Cutting branches from a standing tree: A thick branch should initially be cut off at a point away from the trunk of the tree. First cut in about one third of the way from below, and then cut off the branch from above. Finally, cut off the remaining portion of the branch even with the trunk of the tree. (Fig. 28) CAUTION ○ Always be careful to avoid falling branches. ○ Always be alert for chain saw recoil. (2) Cutting branches from fallen trees: First cut off branches that do not touch the ground, then cut off those which touch the ground. When cutting thick branches that touch the ground, fi rst cut in about half of the way from above, then cut the branch off from below. (Fig. 29) CAUTION ○ When cutting off branches which touch the ground, be careful that the guide bar does not become bound by pressure. ○ During the fi nal cutting stage, beware of the log suddenly rolling.

When cutting a log positioned as shown in Fig. 30, fi rst cut in about one third of the way from below, then cut down all the way from above. When cutting a log that straddles a hollow as shown in Fig. 31, fi rst cut in about two thirds of the way from above, then cut upward from below. CAUTION ○ Ensure the guide bar does not become bound in the log by pressure. ○ When working on inclined ground, be sure to stand on the uphill side of the log. If you stand on the downhill side, the cut-off log may roll toward you.

(1) Undercut ( as shown in Fig. 32): Make undercut facing the direction in which you want the tree to fall. The depth of the undercut should be 1/3 of the tree’s diameter. Never fell trees without proper undercut. (2) Back cut ( as shown in Fig. 32): Make a backcut about 5 cm above and parallel to the horizontal undercut. If the chain becomes entangled during cutting, stop the saw and use wedges to free it. Do not cut thorough the tree. CAUTION ○ Trees should not be felled in a manner that would endanger any person, strike any utility line or cause any property damage. ○ Be sure to stand on the uphill side of the terrain as the tree is likely to roll or slide downhill after it is felled. Precaution for cutting work For large-scale operation or non-stop work To protect the motor and electronics contained in this unit, if it is exposed to high temperature, this is signaled by a fl ashing LED light. If you cut or push forcibly with a high load or non-stop, the motor and electronics will heat up and the LED light will fl ash. NOTE ○ If the LED light fl ashes, stop using and please allow the unit to cool suffi ciently. If you continue to use it, the unit may sustain damage. ○ In addition, if you work non-stop, when replacing the battery, please allow the unit to cool down for at least 15 minutes. ○ In addition, when work is interrupted, if the LED light fl ashes when you turn the switch back on, this means the unit has not cooled suffi ciently, so please allow longer downtime before switching back on. Gripping/pushing force of chain saw Always grip the chain saw securely. In addition, do not force the chain saw more than necessary. When cutting, additional force exerted on the chain saw will not accelerate the cutting speed. This will strain the motor, impair the performance, and damage or cause malfunction of the motor or guide bar. Use the unit in the range where the saw chain is at a reasonable speed. In particular, when the saw chain stops (becomes jammed) due to the excessive force, it may cause an injury or failure of the unit. Chain catcher ○ The chain catcher is located on the power head just below the chain to further prevent the possibility of a broken chain striking the chain saw user. ○ When the saw chain is cut, replace it with a new one referring to “Installing (replacing) saw chain”.

SHARPENING OF THE CHAIN BLADE

WARNING To prevent accidents, always turn off the switch and remove the storage battery from the main body. In addition, when using saw chains, always wear thick gloves. NOTE Sharpen the saw chain and adjust the depth gage at the central position on the guide bar, with the saw chain attached to the main body. When the sharpness of saw chains deteriorates, the motor and each part of the body are burdened and the effi ciency declines. For optimal performance of the unit, frequent maintenance is necessary to keep the saw chain sharp.

The round fi le should be held against the chain blade so that one-fi fth of its diameter extends above the top of the blade, as shown in Fig. 33. Sharpen the blades by keeping the round fi le at a 30° angle in relation to the guide bar, as shown in Fig. 34, ensuring that the round fi le is held straight, as shown in Fig. 35. Ensure that all saw blades are fi led at the same angle, or the cutting effi ciency of the tool will be impaired. Appropriate angles for sharpening the blades correctly are shown in Fig. 36. (Round fi le is sold separately.)

2. Adjustment of depth gage

WARNING ○ Do not sand the top part of the bumper tie strap and guard drive link, nor cause the shape of said parts to deform. 000BookCS3630DA.indb16000BookCS3630DA.indb16 2019/07/2917:49:382019/07/2917:49:3817 English

4. Cleaning the guide bar (Figs. 9, 43)

When sawdust and similar become clogged in the groove of the guide bar or oil spout, the oil may not fl ow, which may result in the unit failing. Remove the guide bar and clean any sawdust clogged in the groove after use and when replacing the saw chain. (Refer to “Installing (replacing) saw chain.”)

5. Inspecting the carbon brushes (Fig. 44)

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.

6. 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 slotted head screw driver, etc., as shown in Fig. 45. When installing the carbon brush, choose the direction so that the nail of the carbon brush (see Fig. 46) agrees with the contact portion of brush tube. Then push it in with a fi nger as illustrated in Fig. 47. Lastly, install the brush cap. CAUTION ○ Be absolutely sure to insert the nail of the carbon brush into the contact portion of 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.

7. 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.

8. 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.

9. Inspection of terminals (tool and battery)

Check to make sure that swarf and dust have not collected on the terminals. On occasion check prior, during and after operation. CAUTION Remove any swarf or dust which may have collected on the terminals. Failure to do so may result in malfunction.

10. Cleaning of the outside

When the chain 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, for they melt plastics.

When storing the unit, perform cleaning and maintenance of each part and mount the chain case to the guide bar. Store the chain saw in a place where the temperature is less than 40°C and out of reach of children. NOTE Storing Lithium-ion Batteries Make sure the lithium-ion batteries have been fully charged before storing them. Prolonged storage (3 months or more) of batteries with a low charge may result in performance deterioration, signifi cantly reducing battery usage time or rendering the batteries incapable of holding a charge. ○ Adjustment of depth gages must be in line with the predetermined dimensions and shapes, otherwise the risk of kickback may increase, causing an injury. Bumper tie strap Guard drive link Depth gages shall be all lined up in the same manner because they are used to adjust depth at the position where the cutter inlays into the wood. When sharpening the saw chain, be sure to check the depth gage every two or three times. Place a depth gage jointer on the saw chain, leave the gage visible at the groove, and use a fl at fi le to bevel the portion out of the depth gage jointer. (Fig. 38) (Depth gage jointer and fl at fi le are sold separately.) After fi ling away the depth gage, round off the front side of the depth gage as it was. (Fig. 39) After sharpening the saw chain, place it into chain oil to wash off the fi lings. If fi lings are not cleaned off , the saw chain and guide bar will quickly wear while in use.
