User manual MAKITA BVR440

[. . . ] Intended use The tool is intended for removing bubbles from concrete when casting concrete. Safety hints For your own safety, please refer to the enclosed safety instructions. MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury. DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to concrete vibrator safety rules. [. . . ] Do not short the battery cartridge: (1) Do not touch the terminals with any conductive material. A battery short can cause a large current flow, overheating, possible burns and even a breakdown. Do not store the tool and battery cartridge in locations where the temperature may reach or exceed 50°C (122°F). Do not incinerate the battery cartridge even if it is severely damaged or is completely worn out. Always stop tool operation and charge the battery cartridge when you notice less tool power. Removal of the air bubbles is complete after you have worked the tool throughout each effective range, the concrete stops shrinking, and the mortar has risen evenly to the surface, giving off a light appearance. nOTE: · Vibrating too long in a single place causes concrete segregation. ⷠWhen the coarse aggregate segregates when placing concrete, shovel out the coarse aggregate and put it where there is plenty of mortar. When concreting a slope site, always pour from the bottom at the beginning. This way the weight of the freshly poured concrete and vibration will lead to effective removal of air bubbles. Conversely, if the pouring is done first from above, the mortar will separate and eventually slide to the bottom. Always be sure that the tool is switched off and the battery cartridge is removed before adjusting or checking function on the tool. Always switch off the tool before insertion or removal of the battery cartridge. To open the cover, press its recessed part and pivot it with the recessed part depressed. And then withdraw it from the tool while sliding the button on the front of the cartridge. ⷠTo insert the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into place. Always insert it all the way until it locks in place with a little click. If you can see the red part on the upper side of the button, it is not locked completely. If not, it may accidentally fall out of the tool, causing injury to you or someone around you. ⷠDo not use force when inserting the battery cartridge.
