change the plug in any way. Double insulation eliminates the need for the three wire grounded power cord and grounded power supply system. 5. Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is grounded. 6. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. 7. Do not abuse the cord.
22. Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool, may become hazardous when used on another tool. SERVICE 23. Tool service must be performed only by qualified repair personnel. Service or main- tenance performed by unqualified personnel could result in a risk of injury. 24. When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual.
. Do not cut oversize workpiece. 6. Check for the proper clearance beyond the workpiece before cutting so that the blade will not strike the floor, workbench, etc. 7. Hold the tool firmly. 8. Make sure the blade is not contacting the workpiece before the switch is turned on. 9. Keep hands away from moving parts. 11. Always switch off and wait for the blade to come to a complete stop before removing the blade from the workpiece. 12.
FUNCTIONAL DESCRIPTION • 001906 1 1. Cutting action changing lever Selecting the cutting action This tool can be operated with an orbital or a straight line (up and down) cutting action. The orbital cutting action thrusts the blade forward on the cutting stroke and greatly increases cutting speed. To change the cutting action, just turn the cutting action changing lever to the desired cutting action position. Refer to the table below to select the cutting action.
Refer to the table to select the proper speed for the workpiece to be cut. However, the appropriate speed may differ with the type or thickness of the workpiece. In general, higher speeds will allow you to cut workpieces faster but the service life of the blade will be reduced. Workpiece to be cut Wood Mild steel Stainless steel Aluminum Plastics • Number on adjusting dial 4-5 3-5 3-4 3-5 1-4 CAUTION: The speed adjusting dial can be turned only as far as 5 and back to 1.

(1) Tilt the tool up on the front edge of the base, with the blade point positioned just above the workpiece surface. (2) Apply pressure to the tool so that the front edge of the base will not move when you switch on the tool and gently lower the back end of the tool slowly. (3) As the blade pierces the workpiece, slowly lower the base of the tool down onto the workpiece surface.

WARNING Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: • lead from lead-based paints, • crystalline silica from bricks and cement and other masonry products, and • arsenic and chromium from chemically-treated lumber. Your risk from these exposures varies, depending on how often you do this type of work.
