PRECAUTIONS ON USING JIG SAW
1. Hold power tool by insulated gripping surfaces, when
performing an operation where the cutting accessory
may contact hidden wiring or its own cord. Cutting
accessory contacting a "live" wire may make exposed
metal parts of the power tool "live" and could give
the operator an electric shock.

1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specified on the product
nameplate.

2. This Jig saw employs a high-power motor. If the
machine is used continuously at low speed, an extra
load is applied to the motor which can result in motor
seizure. Always operate the power tool so that the
blade is not caught by the material during operation.
Always adjust the blade speed to enable smooth
cutting.

When the work area is removed from the power
source, use an extension cord of sufficient thickness
and rated capacity. The extension cord should be kept
as short as practicable.
4. Dust produced in operation
The dust produced in normal operation may affect
the operator's health. Either of following way is
recommended.
a) Wear a dust mask

Confirm the blade located between the groove of
roller. (Fig. 3)
6. Adjusting the blade operating speed
This Jig Saw is equipped with the electric control
circuit which enables stepless speed control. To adjust
the speed, turn the dial shown in Fig. 4. When the dial
is set to "1", the jig saw operates at the minimum
