[. . . ] Contact with a "live" wire will also make exposed metal parts of the power tool "live" and shock the operator. This improves the accuracy cut and reduces the chance of blade binding. Always use blades with correct size and shape (diamond versus round) of arbour holes. Blades that do not match the mounting hardware of the saw will run eccentrically, causing loss of control. [. . . ] Always observe that the lower guard is covering the blade before placing saw down on bench or floor. An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in its path. Be aware of the time it takes for the blade to stop after Before setting the tool down after completing a cut, be sure that the lower guard has closed and the blade has come to a complete stop. Use extra caution when cutting damp wood, pressure treated lumber, or wood containing knots. Adjust speed of cut to maintain smooth advancement of tool without decrease in blade speed. Place the wider portion of the saw base on that part of the workpiece which is solidly supported, not on the section that will fall off when the cut is made. Never attempt to saw with the circular saw held upside down in a vise. 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. Charge the Lithium-ion battery cartridge when you do not use it for more than six months. Always be sure that the tool is switched off and the battery cartridge is removed before adjusting or checking function on the tool. WARNING: MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury. Always switch off the tool before insertion or removal of the battery cartridge. ⷠTo remove the battery cartridge, withdraw it from the tool while sliding the button on the side 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. If the cartridge does not slide in easily, it is not being inserted correctly. [. . . ] Set the base on the workpiece to be cut without the blade making any contact. 24) 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. These accessories or attachments are recommended for use with your Makita tool specified in this manual. The use of any other accessories or attachments might present a risk of injury to persons.
