[. . . ] Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries. Carrying power tools with your finger on the switch or plugging in power tools that have the switch on invites accidents. [. . . ] Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tools operation. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. In accordance with these instructions and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation. WARNING: MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury. Have your power tool serviced by a qualified repair person using only identical replacement parts. CAUTION: Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool. CAUTION: Before plugging in the tool, always check to see that the slide switch actuates properly and returns to the "OFF" position when the rear of the slide switch is depressed. ⷠSwitch can be locked in "ON" position for ease of operator comfort during extended use. For continuous operation, press the front of the slide switch to lock it. CAUTION: Always be sure that the tool is switched off and unplugged before carrying out any work on the tool. For JS1660 Only Adjust the clearance between the side blade and the center blade according to the thickness of the workpiece. Before operation, lubricate the contact point of the center blade and the pin. To keep good cutting performance, also use a cutting lubricant from time to time during operation. Turn the tool on and set front ends of the side blades on the workpiece. Now simply move the tool forward, keeping the side blades flush with the workpiece surface. CAUTION: When cutting a small portion of the workpiece, you may have difficulty completing the end of the cut.
