Bosch Power Tools 4 | English usGeneral Power Tool Safety Warnings Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in elec- tric 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 bat- tery-operated (cordless) power tool. 1) Work area safety a) Keep work area clean and well lit. Clut- tered 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 the risk of electric shock. b) Avoid body contact with earthed or grounded surfaces, such as pipes, radia- tors, 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. Dam- aged or entangled cords increase the risk of electric shock. e) When operating a power tool outdoors, use an extension cord suitable for out- door use. Use of a cord suitable for out- door use reduces the risk of electric shock. f) If operating a power tool in a damp loca- tion is unavoidable, use a ground fault cir- cuit interrupter (GFCI) or an earth leak- age circuit breaker (ELCB). Use of a GFCI or an ELCB reduces the risk of electric shock. 3) Personal safety 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. Al- ways wear eye protection. Protective equipment such as dusk mask, non-skid safety shoes, hard hat or hearing protec- tion 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 bat- tery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents. d) Remove any adjusting key or wrench be- fore turning the power tool on. A wrench or a key that is left attached to a rotating part of the power tool may result in per- sonal injury. e) Do not overreach. Keep proper footing and balance at all times. This enables bet- ter control of the power tool in unexpected situations. f) Dress properly. Do not wear loose cloth- ing or jewelry. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts. WARNING OBJ_BUCH-546-001.book Page 4 Friday, November 9, 2007 8:43 AM

Bosch Power Tools 1 609 929 M72 | (9.11.07) g) If devices are provided for the connection of dust extraction and collection facili- ties, 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 cor- rect power tool for your application. The correct power tool will do the job better and safer at the rate for which it is de- signed. b) Do not use the power tool if the switch does not turn it on or 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 adjust- ments, changing accessories, or storing power tools. Such preventive safety mea- sures 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 unfa- miliar with the power tool or these in- structions to operate the power tool. Power tools are dangerous in the hands of untrained users. e) Maintain power tools. Check for misalign- ment or binding of moving parts, break- age of parts and any other condition that may affect 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. Prop- erly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. g) Use the power tool, accessories, tool bits etc. in accordance with these instruc- tions, taking into account the working conditions and the work to be performed. Use of the power tool for operations differ- ent from those intended could result in a hazardous situation. 5) Service a) Have your power tool serviced by a quali- fied repair person using only identical re- placement parts. This will ensure that the safety of the power tool is maintained. Power Tool-specific Safety Warnings f Do not use the power tool with a damaged cord. Do not touch the damaged cord and pull the plug from the outlet when the cord is damaged while working. Damaged cords increase the risk of an electric shock. f Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand. f Always wait until the power tool has come to a complete stop before placing it down. The tool insert can jam and lead to loss of control over the power tool. OBJ_BUCH-546-001.book Page 5 Friday, November 9, 2007 8:43 AM

Bosch Power Tools 1 609 929 M72 | (9.11.07) Operation Method of Operation The tool holder 5 with the tool is driven by an electric motor via a gear and impact mechanism. The working procedure is divided into two phas- es: Screwing in and tightening (impact mechanism in action). The impact mechanism is activated as soon as the screwed connection runs tight and thus load is put on the motor. In this instance, the impact mechanism converts the power of the motor to steady rotary impacts. When loosening screws or nuts, the process is reversed. Overloading the motor is not possible, as the hammer mechanism disengages when reaching the rated load. Starting Operation f Observe correct mains voltage! The voltage of the power source must agree with the voltage specified on the type plate of the power tool. Reversing the Rotational Direction (see figure A) The rotational direction switch 4 is used to re- verse the rotational direction of the machine. However, this is not possible with the On/Off switch 3 actuated. n Right rotation: Press the rotational direction switch 4 rightward to the stop. o Left rotation: Press the rotational direction switch 4 leftward to the stop. Switching On and Off For starting operation, press the On/Off switch 3 and keep it pressed. To switch off the machine, release the On/Off switch 3. Adjusting the Speed The speed of the switched on power tool can be variably adjusted, depending on how far the On/Off switch 3 is pressed. Light pressure on the On/Off switch 3 results in a low rotational speed. Further pressure on the switch results in an increase in speed. Preselecting the Speed The required speed can be preselected with the dial control 2 (also while running). Working Instructions f Apply the power tool to the screw/nut only when it is switched off. Rotating tool inserts can slip off. The torque depends on the impact duration. The maximum achieved torque results from the sum of all individual torques achieved through impact. The maximum torque is achieved after an impact duration of 3-5 seconds. After this duration, the tightening torque is increased only minimally. However, the transmission housing heats up no- ticeably. Note: The consequences of excessive heating-up are high wear of all hammer mechanism compo- nents and a high requirement of lubricant. The impact duration is to be determined for each required tightening torque. The actually achieved tightening torque is always to be checked with a torque wrench. OBJ_BUCH-546-001.book Page 7 Friday, November 9, 2007 8:43 AM

Bosch Power Tools 8 | English Screw Applications with Hard, Spring-loaded or Soft Seat When in a test, the achieved torques in an impact series are measured and transferred into a dia- gram, the result is the curve of a torque charac- teristic. The height of the curve corresponds with the maximum reachable torque, and the steep- ness indicates the duration in which this is achieved. A torque gradient depends on the following fac- tors: – Strength properties of the screws/nuts – Type of backing (washer, disc spring, seal) – Strength properties of the material being screwed/bolted together – Lubrication conditions at the screw/bolt con- nection The following application cases result accordingly: – A hard seat is given for metal-to-metal screw applications with the use of washers. After a relatively short impact duration, the maximum torque is reached (steep characteristic curve). Unnecessary long impact duration only causes damage to the machine. – A spring-loaded seat is given for metal-to- metal screw applications, however with the use of spring washers, disc springs, studs or screws/nuts with conical seat as well as when using extensions. – A soft seat is given for screw applications, e. g., metal on wood or when using lead wash- ers or fiber washers as backing. For a spring-loaded seat as well as for a soft seat, the maximum tightening torque is lower than for a hard seat. Also, a clearly longer impact duration is required. Reference Values for Maximum Screw/Bolt Tightening Torques Calculated from the tensional cross-section; utilization of the yield point 90 % (with friction coefficient μtotal = 0.12). As a control measure, always check the tightening torque with a torque wrench. Tips Torque rods have shanks with precisely calibrat- ed, reduced diameters. Thus, they act torque-lim- iting. A torque rod is placed between the impact wrench and the bit. Rule of thumb for the application: Core diameter of the screw/bolt = effective diameter of the torque rod. The impact duration is to be deter- mined through practical testing. The thumbwheel 2 must be set to max. here. For hanging up, a suspension hook 1 is mounted at the machine's centre of gravity. At temperatures below the freezing point, run the machine for approx. 3 minutes at no-load to improve its lubricating capacity.

Bosch Power Tools 1 609 929 M72 | (9.11.07) 安装 更换工具 f 维修电动工具或换装零、配件之前，务必 从插座上 拔出插头。 f 在机器上安装好工具之后，必须检查插入工具是否已 经牢牢地固定 在机器的接头上。 如果插入工具的柄 未牢牢地套在接头中， 工具柄容易从接头上脱开， 并 产生操作者无法控制机器的情况。 把插入工具 6 套在工具接头 5 上。 操作 运作原理 工具接头5 和安装在接头上的工具，是靠著电子马达带 动传动装置和敲击体来驱动的。 整个运作过程可以划分为两个阶段： 旋转 和 拧紧 （冲击体投入运作）。 一当螺丝咬入工件中而且发动机开始受荷，冲击体便投 入运作。冲击体把发动机的传动力转换为均匀的旋转式 敲击动作。放松螺丝或螺母时，整个运作过程会反向进 行。 马达不会过载。因为到达额定负载之后，敲击体便会自 动脱离联结。 操作机器 f 注意电源的电压！电源的电压必须和电动工具铭牌上 标示的电压一致。 改变转向 （参考插图A） 使用正逆转开关 4 可以改变机器的转向。如果按住了起 停开关 3，则无法改变转向。 n 正转： 把转向变换开关 4 向右推到尽头。 o 逆转： 把转向变换开关 4 向左推到尽头。 开动 / 关闭 开动 机器，按住起停开关 3。 放开 起停开关 3 便可以关闭机器。 调整转速 你可以无级式调整转速，把起停开关 3 按得越紧，转速 就越快。 轻按起停开关 3 机器以低转速运转。逐渐在开关上加 压， 转速也会跟著提高。 设定转速 使用转速调整轮 2，即使在机器运作当中也可以设定须要 的转速。 有关操作方式的指点 f 先关闭电动工具，然后再把工具放置在螺母/螺丝上。 安装在接头上的工具如果仍继续转动，容易从螺丝头 上滑开。 扭力大小和冲击时间长短有关。最大扭力是所有经由冲 击所产生的单一扭力的总和。在冲击约 3-5 秒之后扭力 可以达到最大。超过这段时间，拉紧扭力只轻微增加。 而传动装置壳却会明显变热。 指示： 机器过热不仅会提高所有敲击零件的磨损率，而 且也会增加润滑剂的消耗量。 必须测量每个拉紧扭力的持续冲击时间。随时以扭力测 量仪，检查测得的拉紧扭力。 硬垫拧转，弹簧垫拧转或软垫拧转。 如果把单一冲击过程中测得的各个扭力记载在线图上， 可以得到扭力变化的曲线。曲线的最高点是最大扭力。 上升的线段则代表到达最大扭力所须的时间。 扭力曲线的演变会受以下因素影响： – 螺丝/ 螺母的强度 – 垫片的种类（螺片，冠状弹簧，密封片） – 即将被拧入螺丝的物料的强度 – 螺丝是否涂抹了润滑油 OBJ_BUCH-546-001.book Page 13 Friday, November 9, 2007 8:43 AM

Bosch Power Tools 14 | 中文 综合以上因素，大概可以归类出下列的工作状况： – 硬垫拧转， 是指在使用垫片的前提下把金属螺丝拧入 金属物料中。经过短暂的冲击之后便可以达到最大扭 力（比较陡的上升曲线）。不必要的延长冲击时间只 会损坏机器。 – 弹簧垫拧转， 是指在使用了弹簧圈、冠状弹簧、螺 栓、带圆锥座的螺丝/ 螺母以及延长零件等的情况下 把金属螺丝拧入金属物料中。 – 软垫拧转， 以下几个例子都属于软垫拧转：把金属螺 丝拧入木材中，或者拧紧螺丝时使用了铅垫片、纤维 垫片。 弹簧垫拧转和软垫拧转的最大扭力小於硬垫拧转的最大 扭力。而且前者需要的冲击时间却明显超越后者。 最大螺丝拉紧扭力的参考值 所提供的数据的单位是牛顿米，数据是由切削截面积运算所得；屈服点的利用为百分之90 % （在摩擦系数 μ 时= 0,12 ）。随时以扭力测量仪检查拉紧扭力。 建议 扭力棒的柄不仅经过准确的校准，而且直径比较小。 因 此扭力棒具备了限制扭力的功能。 扭力棒一般都安装在 冲击扳手和批嘴之间。 根据经验，使用时的规则如下： 螺丝的核心直径= 扭力 棒的运作直径。 敲击时间必须由实际的拧转过程得知。 调整轮 2 必须设定在最大 上。 为了方便悬挂机器，在电动工具的重心上配备了一个挂 钩 1。 如果工作场所的温度位在零度以下，正式操作之前必须 先让机器空转3 分钟， 以改善机器内部的润滑情况。 强度等级根据DIN 267 标准螺丝 高强度螺丝 3.6 4.6 5.6 4.8 6.6 5.8 6.8 6.9 8.8 10.9 12.9 M 6 2.71 3.61 4.52 4.8 5.42 6.02 7.22 8.13 9.7 13.6 16.2 M 8 6.57 8.7 11 11.6 13.1 14.6 17.5 19.7 23 33 39 M 10 13 17.5 22 23 26 29 35 39 47 65 78 M 12 22.6 30 37.6 40 45 50 60 67 80 113 135 M 14 36 48 60 65 72 79 95 107 130 180 215 M 16 55 73 92 98 110 122 147 165 196 275 330 M 18 75 101 126 135 151 168 202 227 270 380 450 M 20 107 143 178 190 214 238 286 320 385 540 635 OBJ_BUCH-546-001.book Page 14 Friday, November 9, 2007 8:43 AM
