GENERAL POWER TOOL SAFETY WARNINGS

WARNING Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire 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 flammable 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. Unmodified 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. 2023/02/01 17:17:45Stylesheet: NA Version: 2023.1.25 WR18DH_C99749061_301_NAEnglish

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 influence 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 a 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 finger 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 and clothing 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. h) Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

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 remove the battery pack, if detachable, 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 and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power toolʼs 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 different from those intended could result in a hazardous situation. h) Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

5) Battery tool use and care

A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack. b) Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire. 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 fire. d) Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns. e) Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury. f) Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 265°F may cause explosion. g) Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

a) Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained. b) Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers. WARNING To reduce the risk of injury, user must read instruction manual.

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 first and second time. This is a temporary phenomenon, and normal time required for recharging will be restored by recharging the batteries 2–3 times. 2023/02/01 17:17:45Stylesheet: NA Version: 2023.1.25 WR18DH_C99749061_301_NAEnglish

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. 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. OPERATION

1. Selecting the socket matched to the bolt

Be sure to use a socket which is matched to the bolt to be tightened. Using an improper socket will not only result in insufficient tightening but also in damage to the socket or nut. A worn or deformed hex. or square-holed socket will not give an adequate tightness for fitting to the nut or anvil, consequently resulting in loss of tightening torque. Pay attention to wear of socket hole, and replace before further wear has developed.

2. Installing a socket

Select the socket to be used. (1) Slide the O-ring out of the groove, then align the hole of the socket with the hole of the anvil and insert the anvil into the socket. Friction ring Hole of anvil Hole of socket O-ring Fig. 8 (2) Insert the pin into the socket. Pin Fig. 9 (3) While making sure that the pin doesn’t fall, attach the O-ring to the groove on the socket. O-ring Fig. 10 Groove Friction ring Hole of anvil Hexagonal socket Anvil Hole Fig. 11 CAUTION

Please use the designated attachments which are listed in the operations manual and metaboHPT’s catalog. Accidents or injuries could result from not doing so.

Make sure to firmly install the socket in the anvil. If the socket is not firmly installed it might come out and cause injuries.

When sliding the O-ring out of the groove of the socket, be careful not to drop and lose the pin.

3. Confirm that the battery is mounted correctly.

The bit rotates clockwise (viewed from the rear side) by pushing the R-side of the pushing button. The L-side of the pushing button is pushed to turn the bit counterclockwise. (See Fig. 12). (The and marks are engraved on the body.) Push Trigger switch Pushing button Push marks marks Fig. 12 CAUTION The pushing button can not be switched while the impact wrench is turning. To switch the pushing button, stop the impact wrench, then set the pushing button.

When the trigger switch is depressed, the tool rotates. When the trigger is released, the tool stops.

The rotational speed can be controlled by varying the amount that the trigger switch is pulled. Speed is low when the trigger switch is pulled slightly and increases as the trigger switch is pulled more.

When releasing the trigger switch, the brake will be applied for immediate stopping. NOTE A buzzing noise is produced when the motor is about to rotate; this is only a noise, not a machine failure.

6. Tightening and loosening bolts

A hex. socket matching the bolt or nut must first be selected. Then mount the socket on the anvil, and grip the nut to be tightened with the hex. socket. Holding the wrench in line with the bolt, press the power switch to impact the nut for several seconds. If the nut is only loosely fitted to the bolt, the bolt may turn with the nut, therefore mistaking proper tightening. In this case, stop impact on the nut and hold the bolt head with a wrench before restarting impact, or manually tighten the bolt and nut to prevent them slipping.

The hook is used to hang up the power tool to your waist belt while working. You can switch between attaching it on the left or right. WARNING When using the hook, hang up the power tool firmly not to drop accidentally. If the power tool is dropped, it may lead to an accident. CAUTION

When electing to carry the tool hooked to your hip belt, make sure to detach the tool bit. Failure to do so may result in unexpected injury.

Tightening torque can be adjusted according to the type of work by combined use of the High / Low mode selector switch and the auto stop mode selector switch. (Fig. 17) Auto stop mode selector switch High / Low mode selector switch Fig. 17 (1) High / Low mode selector switch (Fig.18) The tightening mode switches between 4 different rotation speeds each time the High / Low mode selector switch is pressed.

Fig. 18 Table 6: High / Low mode selector function setting Indicator lamps Maximum unloaded speed (/min) Uses 1 1,200 For work that requires fine adjustments. 2 1,800 For work that requires the power to be suppressed. 3 2,400 4 2,800 For work that requires a priority on power and speed. (2) Auto stop mode selector switch Pressing the Auto stop mode selector switch toggles the mode. Forward: Auto stop mode Reverse: Auto slow mode Auto stop mode selector switch Fig. 19

Auto stop mode Stops automatically after a preset time has elapsed. Push the pushing button to the forward (“R”) position, then press the Auto stop mode selector switch to select the setting. (see Table 7)

Auto slow mode (See Table 8) Stops for a preset time and/or changes the speed automatically to a preset speed. Push the pushing button to the reverse (“L”) position, then press the Auto stop mode selector switch to select the setting.

Pauses after bolt loosening is detected. Restarts after stopping for 0.5seconds, then rotates at 350 /min.

Rotation does not stop after restarting. *2 Trigger displacement: Halfway

Rotation speed is reduced depending on how far the trigger is pulled after starting.

Rotation does not stop. NOTE

This function helps prevent nuts from dropping when loosening them.

Depending on factors such as the bolt or nut size, socket used, and extent of tightening, there is a risk of nuts accidentally dropping if the nut becomes detached from the screw thread while the power tool is operating.

The appropriate mode differs depending on the bolt and the material being screwed. Tighten in a few test bolts and adjust the mode setting accordingly.

The tightening mode selector switch can only be set after the battery has been installed in the wrench and the trigger switch has been pulled once. OPERATIONAL CAUTIONS

1. Resting the unit after continuous work

After use for continuous bolt-tightening work, rest the unit for 15 minutes or so when replacing the battery. The temperature of the motor, switch, etc., will rise if the work is started again immediately after battery replacement, eventually resulting in burnout. 2023/02/01 17:17:45Stylesheet: NA Version: 2023.1.25 WR18DH_C99749061_301_NAEnglish

CAUTION Do not touch the hammer case as it gets very hot during continuous work.

2. Cautions on use of the speed control switch

This switch has a built-in, electronic circuit which steplessly varies the rotation speed. Consequently, when the trigger switch is pulled only slightly (low speed rotation) and the motor is stopped while continuously driving in screws, the components of the electronic circuit parts may overheat and be damaged.

3. Work at a tightening torque suitable for the bolt under

impact The optimum tightening torque for nuts or bolts differs with material and size of the nuts or bolts. An excessively large tightening torque for a small bolt may stretch or break the bolt. The tightening torque increases in proportion to the operation time. Use the correct operating time for the bolt.

Hold the tool firmly with both hands. In this case hold the tool in line with the bolt. It is not necessary to push the tool very hard. Hold the tool with a force just sufficient to counteract the impact force.

5. Confirm the tightening torque

The following factors contribute to a reduction of the tightening torque. So confirm the actual tightening torque needed by screwing up some bolts before the job with a hand torque wrench. Factors affecting the tightening torque are as follows. (1) Voltage When the discharge margin is reached, voltage decreases and tightening torque is lowered. (2) Operating time The tightening torque increases when the operating time increases. But the tightening torque does not increase above a certain value even if the tool is driven for a long time. (3) Diameter of bolt The tightening torque differs with the diameter of the bolt. Generally a larger diameter bolt requires larger tightening torque. (4) Tightening conditions The tightening torque differs according to the torque ratio; class, and length of bolts even when bolts with the same size threads are used. The tightening torque also differs according to the condition of the surface of workpiece through which the bolts are to be tightened. When the bolt and nut turn together, torque is greatly reduced. (5) Using optional parts The tightening torque is reduced a little when an extension bar, universal joint or a long socket is used. (6) Clearance of the socket A worn or deformed hex. or a square-holed socket will not give an adequate tightness to the fitting between the nut or anvil, consequently resulting in loss of tightening torque. Using an improper socket which does not match to the bolt will result in an insufficient tightening torque. (7) Tightening torque varies, depending on the battery’s charge level.

MAINTENANCE AND INSPECTION

WARNING Be sure to turn off the switch and pull out the battery before doing any inspection or maintenance.

1. Checking the condition of the socket

A worn or deformed hex. or a square-holed socket will not give an adequate tightness to the fitting between the nut or anvil, consequently resulting in loss of tightening torque. Pay attention to wear of a socket holes periodically, and replace with a new one if needed.

Loose screws are dangerous. Regularly inspect them and make sure they are tight. CAUTION Using this power tool 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. 2023/02/01 17:17:45Stylesheet: NA Version: 2023.1.25 WR18DH_C99749061_301_NAEnglish

Dust may be removed with a soft cloth or a cloth dampened with soapy water. Do not use bleach, chlorine, gasoline or thinner, for they may damage the plastics.

5. 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.

6. Disposal of the exhausted battery

WARNING Do not dispose of the exhausted battery. The battery must explode if it is incinerated. The product that you have purchased contains a rechargeable battery. The battery is recyclable. At the end of it’s useful life, under various state and local laws, it may be illegal to dispose of this battery into the municipal waste stream. Check with your local solid waste officials for details in your area for recycling options or proper disposal.

Store the power tool and the battery in a place in which the temperature is less than 104°F (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 (3months or more) of batteries with a low charge may result in performance deterioration, significantly reducing battery usage time or rendering the batteries incapable of holding a charge. However, significantly reduced battery usage time may be recovered by repeatedly charging and using the batteries two to five times. If the battery usage time is extremely short despite repeated charging and use, consider the batteries dead and purchase new batteries.
