7. 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:
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".
