General Power Tool Safety Instructions 몇 WARNING ● Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future ref- erence. The term "power tool" in the safety instructions refers to your mains-operated (corded) power tool or battery-op- erated (cordless) power tool. 1 Work safety a Keep your work area clean and well-lit. Untidy or unlit work areas can lead to accidents. b Do not operate power tools in explosive at- mospheres, such as in the presence of flam- mable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes. c Keep children and bystanders away while op- erating a power tool. Distractions can cause you to lose control of the device. 2 Electrical safety a Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of elec- tric shock if your body is earthed or grounded. b Do not expose power tools to rain or wet con- ditions. Water entering a power tool will increase 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 med- ication. A moment of inattention while operating power tools may result in serious personal injury. b Use personal protective equipment and al- ways wear safety goggles. Protective equip- ment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropri- ate conditions will reduce the risk of personal in- juries. c Prevent unintentional starting. Ensure that the power tool is switched off before connect- ing the power supply and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or connecting the power supply to a device that is already switched on can lead to 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 a firm footing and maintain your balance at all times. This ena- bles better control of the power tool in unexpect- ed situations. f Wear suitable clothing. Do not wear loose-fit- ting clothing or dangling jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, gloves, jewellery or long hair can be caught in moving parts. 4 Power tool use and care a Do not overload the device. 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. p. 14

Disconnect the plug from the power source and/or the battery pack before making any ad- justments, changing accessories, or storing the device. Such preventive safety measures re- duce the risk of starting the power tool accidental- ly. d Store unused power tools out of the reach of children. Do not allow persons unfamiliar with the device or these instructions to operate the device. 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 affect the power tool’s operation. If damaged, have the power tool repaired before use. Many acci- dents are caused by poorly maintained power tools. f 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 pow- er tool for operations different from those intend- ed could result in a hazardous situation. 5 Use and care of battery packs a Only charge the battery pack with the charg- ers approved by the manufacturer. Chargers that are not suitable for the corresponding battery pack may cause a fire. b Only use the device with a suitable battery pack. Using a different battery pack may cause injury or fire. c When not in use, keep the battery pack away from metallic objects such as paper clips, coins, keys, nails, screws or other small me- tallic objects that may cause a short-circuit. A short circuit can cause a fire or explosion. d Under certain circumstances, fluid may es- cape from the battery pack. Avoid contact. If you come into contact with the fluid, rinse the corresponding skin thoroughly with water. If you get the fluid in your eye, seek medical at- tention immediately. Battery fluid can cause rashes and burns on the skin. 6 Service a Have your power tool serviced by a qualified repair person using only identical replace- ment parts. This will ensure that the safety of the power tool is maintained.12 English Description of the device Illustration A 1 Battery pack mounting 2 Power switch 3 Lockable spray trigger 4 Spray lance 5 Spray nozzle 6 Filling nozzle with measuring cup 7 Hose connection 8 Hose 9 Shoulder strap support 10 Tank 11 Lock latch 12 *Battery Pack Battery Power 18V 13 *Quick Charger Battery Power 18V 14 Shoulder strap
