User manual MAKITA BVR440

[. . . ] Switch off the tool immediately if you notice abnormal noise or something faulty during operation. Inspect the tool carefully for breakage, cracks or deformation if you accidentally drop it or strike it against something. Do not carry the tool with finger on switch. Do not set the tool down and switch it on. [. . . ] Be careful not to drop or strike battery. 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. Gently remove the operating tool not to leave holes. 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. Insert it fully until the red part cannot be seen. 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. If the cartridge does not slide in easily, it is not being inserted correctly. Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance. To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjustment should be performed by Makita Authorized Service Centers, always using Makita replacement parts.
