User manual MAKITA LS1440

[. . . ] Learn the tool's applications and limitations, as well as the specific potential hazards peculiar to it. Form habit of checking to see that keys and adjusting wrenches are removed from tool before turning it on. Don't use power tools in damp or wet locations, or expose them to rain. MAKE WORKSHOP KID PROOF with padlocks, master switches, or by removing starter keys. [. . . ] CAUTION: After installing a new blade, always be sure that the blade does not contact any part of the lower base when the handle is lowered completely. When you have moved the grip to the position where the pointer points to the desired angle on the miter scale, securely tighten the grip clockwise. CAUTION: When turning the turn base, be sure to raise the handle fully. After changing the miter angle, always secure the turn base by tightening the grip firmly. The fence plate is designed to prevent smaller cutting scraps from jamming inside the blade case. The fence plate moves right or left automatically as the turn base is rotated. CAUTION: Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the "OFF" position when released. Do not pull the switch trigger hard without pressing in the lock-off button. To prevent the switch trigger from being accidentally pulled, a lock-off button is provided. Any tool with an inoperative switch is HIGHLY DANGEROUS and must be repaired before further usage. For your safety, this tool is equipped with a lock-off button which prevents the tool from unintended starting. NEVER use the tool if it runs when you simply pull the switch trigger without pressing the lock-off button. Return tool to a Makita service center for proper repairs BEFORE further usage. If the tool consistently fails to quickly stop blade after switch trigger release, have tool serviced at a Makita service center. CAUTION: Always be sure that the tool is switched off and unplugged before carrying out any work on the tool. CAUTION: Always be sure that the tool is switched off and unplugged before installing or removing the blade. To remove the blade, use the socket wrench to loosen the hex bolt holding the center cover by turning it counterclockwise. Press the shaft lock to lock the spindle and use the socket wrench to loosen the hex bolt clockwise. To install the blade, mount it carefully onto the spindle, making sure that the direction of the arrow on the surface of the blade matches the direction of the arrow on the blade case. Install the outer flange and hex bolt, and then use the socket wrench to tighten the hex bolt (left-handed) securely counterclockwise while pressing the shaft lock. Use the correct side for the hole diameter of the blade you intend to use. Mounting the blade on the wrong side can result in dangerous vibration. [. . . ] The hex lock nut which holds the gear housing and the arm has been factory adjusted to assure smooth handle action up and down and to guarantee precise cutting. Should looseness develop at the gear housing and arm connection, perform the following adjustment. Work the handle up and down while tightening the hex lock nut; the best position to tighten the hex lock nut is just before the motor body weight is obvious. After adjusting the hex lock nut, be sure that the handle returns automatically to the initial, raised position from any position. [. . . ]
