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

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. 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. 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.

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. 00BookH60MEYNA.indb300BookH60MEYNA.indb3 2016/06/0716:29:592016/06/0716:29:594 English A moment of inattention while operating power tools may result in serious personal injury. b) Use personal protective equipment.

HOW TO USE THE DEMOLITION HAMMER

1. After placing the tip of the tool on concrete surface,

switch ON. The switch can be turned ON if the trigger is pulled and OFF when it is released. If the ON-Lock switch is pressed while the trigger for the switch is pulled, even if your fi nger is released from the trigger, the switch remains ON - convenient for continuous operation. To turn the switch OFF, pull the trigger again, and then the ON-Lock switch comes off .

2. By utilizing the empty weight of the machine and by

fi rmly holding the hammer by both hands, you can eff ectively control the subsequent recoil motion. Proceed at a moderate work-rate, the use of too much pushing force will impair effi ciency.

3. Even when the switch is on, the motor is running and

the tool head is pressed to the demolition surface, the hammer sometimes does not start operating. In these instances, turn the switch off , press the tool head against the demolition surface again, and turn the switch on and off . This should start the hammer operating. Repeat this procedure for several minutes, and the hammer will heat, after which it will operate when switched to ON-LOCK. Fig. 12 CAUTION: After long time of use, the housing becomes hot. Therefore, be careful not to burn your hands. 00BookH60MEYNA.indb1000BookH60MEYNA.indb10 2016/06/0716:30:012016/06/0716:30:0111 English
