Adjusting the blade operating speed The jig saw is equipped with the electric control circuit which enables stepless speed control. To adjust the speed, turn the dial shown in Fig. 6. When the dial is set to "1", the jig saw operates at the minimum speed (850 /min.). When the dial set to "5", the jig saw operates at the maximum speed (3000/min.). Adjust the speed according to the material to be cut and working efficiency. CAUTION: ⅷ At low speed (dial setting: 1 or 2) do not cut a wood with a thickness of more than 3/8" (10 mm) or metal with a thickness of more than 1/32" (1 mm). 8. Adjusting the orbital operation (1) This Jig Saw employs orbital operation which moves the blade back and forth, as well as up and down. Set the change knob shown in Fig. 7 to "0" to eliminate the orbital operation (the blade moves only up and down). The orbital operation can be selected in 4 steps from "0" to "III".
