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. 5.
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
(3,000/min.). Adjust the speed according to the
material to be cut and working effi ciency.
CAUTION
● At low speed (dial setting: 1 or 2) do not cut a
wood with a thickness of more than 5/16" (8
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. 6
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".
(2) For the hard material, such as a steel plate,
etc., decrease the orbital operation. For the soft
material, such as lumber, plastic, etc., increase
the orbital operation to increase work effi ciency.
To cut the material accurately, decrease the
orbital operation.
9. Cutting stainless steel plates
This Jig Saw can cut stainless steel plates by
using No. 97 blade. Carefully read "Concerning
cutting of stainless steel plates" for proper
operation.
