An accident can often be avoided by recognizing a potentially hazardous situation before it occurs, and by observing appropriate safety procedures. Basic safety precautions are outlined in the “SAFETY” section of this Instruction Manual and in the sections which contain the operation and maintenance instructions. Hazards that must be avoided to prevent bodily injury or machine damage are identifi ed by WARNINGS on the power tool and in this Instruction Manual. NEVER use this power tool in a manner that has not been specifi cally recommended by metabo HPT.

MEANINGS OF SIGNAL WORDS

WARNING indicates a potentially hazardous situations which, if ignored, could result in death or serious injury. CAUTION indicates a potentially hazardous situations which, if not avoided, may result in minor or moderate injury, or may cause machine damage. NOTE emphasizes essential information. SAFETY

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. Unmodified plugs and matching outlets will reduce risk of electric shock.

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.

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.

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. 00BookWR22SENA.indb300BookWR22SENA.indb3 2018/03/2215:13:322018/03/2215:13:324 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 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, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.

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.

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.

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.

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.

OPERATION To ensure safer operation of this power tool, metabo HPT has adopted a double insulation design. “Double insulation” means that two physically separated insulation systems have been used to insulate the electrically conductive materials connected to the power supply from the outer frame handled by the operator. Therefore, either the symbol “ ” or the words “Double insulation” appear on the power tool or on the nameplate. Although this system has no external grounding, you must still follow the normal electrical safety precautions given in this Instruction Manual, including not using the power tool in wet environments. To keep the double insulation system effective, follow these precautions:

Only metabo HPT AUTHORIZED SERVICE CENTER should disassemble or assemble this power tool, and only genuine metabo HPT replacement parts should be installed.

Clean the exterior of the power tool only with a soft cloth moistened with soapy water, and dry thoroughly. Never use solvents, gasoline or thinners on plastic components; otherwise the plastic may dissolve. 00BookWR22SENA.indb500BookWR22SENA.indb5 2018/03/2215:13:322018/03/2215:13:326 English

Tightening and loosening various kinds of bolts and nuts.

Ensure that the power source to be utilized conforms to the power source requirements specifi ed on the product nameplate.

Ensure that the switch is in the OFF position. If the plug is connected to a receptacle while the switch is in the ON position, the power tool will start operating immediately and can cause serious injury.

When the work area is far away from the power source, use an extension cord of suffi cient thickness and rated capacity. The extension cord should be kept as short as practicable.

Damaged cord must be replaced or repaired.

4. Check the receptacle

If the receptacle only loosely accepts the plug, the receptacle must be repaired. Contact a licensed electrician to make appropriate repairs. If such a faulty receptacle is used, it may cause overheating, resulting in a serious hazard.

5. Confi rming condition of the environment

Confi rm that the work site is placed under appropriate conditions conforming to prescribed precautions. protrusion slot

6. Mounting the side handle

After loosening the handle, slide it over the main unit and tighten the handle to secure it. When sliding over the main unit, make sure to align the unit’s protrusion with the side handle’s slot. (Fig. 2) Fig. 2 Handle 00BookWR22SENA.indb800BookWR22SENA.indb8 2018/03/2215:13:332018/03/2215:13:339 English CAUTION: Be sure to turn the switch OFF and wait until the motor completely stops before changing the direction of wrench revolution. Switching while the motor is rotating will result in burning the motor.

2. Tightening and loosening bolts

A hex. socket matching the bolt or nut must fi rst 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 fi tted to the bolt, the bolt may turn with the nut, therefore preventing 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. Fig. 5

7. Mounting the socket

(1) WR22SE: Plunger type (Fig. 3) Align the plunger located in the square part of the anvil with the hole in the hex. socket. Then push the plunger, and mount the hex. socket on the anvil. Check that the plunger is fully engaged in the hole. When removing the socket, reverse the sequence. (2) WR25SE: Pin, O-ring type (Fig. 4) Select a socket matched to the bolt to be tightened or loosened. Insert the socket on the anvil of the wrench, and secure it with the pin and ring. When dismantling the socket, reverse the sequence.

The switch in this machine functions as a motor switch and rotational direction selector switch. When the switch is set to R indicated on the handle cover, the motor rotates clockwise to tighten the bolt. When the switch is set to L, the motor rotates counterclockwise to loosen the bolt. When the switch is released, the motor stops.

1. Do not touch the bumper or hammer case during continuous operation

The bumper and hammer case become hot during continuous screw tightening so be careful not to touch them at that time.

2. Work at a tightening torque suitable for the bolt under impact

The optimum tightening torque for nuts and bolts diff ers with material and size of the nuts and bolts. An excessively large tightening torque for a small bolt may stretch or break the bolt. The tightening torque increases proportionally to the operating time. Use the correct operating time for the bolt.

3. Selecting the socket to be matched to the bolt

Be sure to use a socket which is matched to the bolt to be tightened. Using an improper socket will result not only in insuffi cient 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 fi tting to the nut or anvil, consequently resulting in loss of tightening torque. Pay attention to wear of socket holes, and replace before further wear has develops. Matching socket and bolt sizes are shown in Table 2. The numerical value of a socket designation denotes the side-to-side distance (S) of its hex. hole.

Hold the Impact Wrench fi rmly with both hands by the body handle and the side handle. In this case hold the wrench in line with the bolt. It is not necessary to push the wrench very hard. Hold the wrench with a force just suffi cient to counteract the impact force.

5. Confi rm the tightening torque

The following factors contribute to a reduction of the tightening torque. So confi rm the actual tightening torque needed by screwing up some bolts before the job with a hand torque wrench. Factors aff ecting the tightening torque are as follows. (1) Line voltage: The tightening torque decreases when the line voltage becomes low. (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. (See Fig. 6) 00BookWR22SENA.indb1000BookWR22SENA.indb10 2018/03/2215:13:332018/03/2215:13:3311 English (3) Diameter of bolt: The tightening torque diff ers with the diameter of the bolt. Generally a larger diameter bolt has a larger tightening torque. (4) Tightening conditions: The tightening torque diff ers according to the torque ratio; class, and length of bolts even when bolts with the same size threads are used. The tightening torque also diff ers according to the condition of the surface of metal through which the bolts are to be tightened. (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 fi tting 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. Matching socket and bolt sizes are shown in Table 2.

6. The protection function

To protect the tool, the protection function will be activated, automatically shutting down the unit in the event of any problems. Table 1 describes each situation for which the aforementioned may occur.

Discontinue the heavy load task and unplug the power cord from the outlet. When the cord is plugged back in, the tool will recover. *2 Increased temperature protection function Automatic shutdown is activated to prevent damage from high temperatures. The tool’s internal temperature will increase for tasks involving the use of large currents of electricity, or when used in high temperature environments. In such cases, let the tool cool down for 10 to 15-minutes before continuing use.

7. Using the hook hanger (WR25SE) (Fig. 7)

When using the hook hanger, make sure the rope or wire is securely fastened to the hanger. CAUTION: Always make sure to use a rope or wire with suffi cient strength to support the weight of the main unit and withstand impact from dropping.

Be sure to switch power OFF and disconnect the plug from the receptacle during maintenance and inspection.

1. Inspecting the socket

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

2. Inspecting the screws

Regularly inspect all screws and ensure that they are properly tightened. Should any of the screws be loosened, retighten them immediately.

Using this impact wrench with loosen 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. Hook Hanger Fig. 7 00BookWR22SENA.indb1200BookWR22SENA.indb12 2018/03/2215:13:332018/03/2215:13:3313 English ACCESSORIES
