A wrench or a key left attached to a rotating part of the power tool may result in personal injury. This enables better control of the power tool in unexpected situations. G) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. [. . . ] table 2 Recharging ranges of batteries Charger Rechargeable batteries BCL1430 , EBM1830 EB14B , EB1820L UC18YRL 0°C ­ 50°C x UC18YG x ­5°C ­ 60°C 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 2­3 times. 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. When using a bit which has big diameter, enlarge the center hole of the dust cup with this rotary hammer. Installing dust collector (B) When using dust collector (B), insert dust collector (B) from the tip of the bit by aligning it to the groove on the grip. 7) CAUTION: The dust cup and dust collector (B) are for exclusive use of concrete drilling work. insert dust collector (B) completely into the chuck part of the main unit. When turning the rotary hammer on while dust collector (B) is detached from a concrete surface, dust collector (B) will rotate together with the drill bit. Make sure to turn on the switch after pressing dust cup on the concrete surface. When using dust collector (B) attached to a drill bit that has more than 190 mm of overall length, dust collector (B) cannot touch the concrete surface and will rotate. Therefore, please use dust collector (B) by attaching to drill bits which have 166 mm, 160 mm, and 110 mm overall length. Selecting the driver bit Screw heads or bits will be damaged unless a bit appropriate for the screw diameter is employed to drive in the screws. 8) The bit rotates clockwise (viewed from the rear side) by pushing the R-side of the push button. The L-side of the push button is pushed to turn the bit counterclockwise. ) CAUTION: The push button cannot be switched while the power tool is turning. To switch the push button, stop the power tool, then set the push button. Continuous drilling The number of holes that can be drilled in concrete after one recharge is shown in Table 3. The number of holes that can be drilled varies according to the sharpness of the used bit or the conditions of the concrete being drilled. CAUTION: When using this unit continuously, the unit may overheat, leading to damage in the motor and switch. CAUTION: When using the light equipped hook, pay sufficient attention so that the main equipment does not fall. [. . . ] further use of the rotary hammer despite the grease shortage causes damage to reduce the service life. CAUTION: A specific grease (FG-6A) is used with this machine, therefore, the normal performance of the machine may be badly affected by use of different grease. Please be sure to let one of our service centers to undertake replacement of the grease. Inspecting the tool Since use of a dull tool will degrade efficiency and cause possible motor malfunction, sharpen or replace the tool as soon as abrasion is noted. [. . . ]
