VI.VI. OPERATIONOPERATION
1. Push the switch lock lever down, pull 
the power switch.
• The speed increases with the amount 
of depression of the power switch.
2. Once cutting is finished, release the 
power switch.
3. Check that the temperature of the blade 
has dropped sufficiently, and then re-
move the blade.
CuttingCutting
 NOTE:
• Check that there are no obstacles 
to cut underneath workpiece.
• Check that there are no objects such 
as nails in the material to be cut.
If the blade comes into contact with 
any such objects during cutting, a 
strong reaction force will be gener-
ated and severe injury may occur.
• 
Do not place your hand on the object 
in the direction cutting is to take place.
If this is not observed, there is a risk 
of injury.
• Do not touch the jigsaw blade im-
mediately after cutting.
If this is not observed, burns may oc-
cur.

object to be cut before pulling the 
power switch.
2. Pull the power switch, wait until the 
speed has stabilized, and then place 
the base against the object to be cut 
and cut along the marked lines.
• When cutting complex shapes such 
as shapes with many small curves, 
reduce the cutting speed and the 
turning speed.
Plunge cutting
1. Make a drill hole in the section to be 
plunge cut in order to let the blade 
pass through.
2. Insert the blade into a hole without 
touching the workpiece, and then turn 
on the power switch.

Cautions for the Li-ion Battery 
Pack
• If the temperature of the battery 
pack falls approximately below 
−10°C (14°F), charging will auto-
matically stop to prevent degrada-
tion of the battery.
Common Cautions for the Li-
ion/Ni-MH/Ni-Cd Battery Pack
• The ambient temperature range is be-
tween 0°C (32°F) and 40°C (104°F).
If the battery pack is used when the 
battery temperature is below 0°C 
(32°F), the tool may fail to function 
properly. 
• When charging a cool battery pack 
(below 0°C (32°F)) in a warm place, 
leave the battery pack at the place 
and wait for more than one hour to 
warm up the battery to the level of 
the ambient temperature.
• Cool down the charger when charg-
ing more than two battery packs 
consecutively.
• Do not insert your fingers into con-
tact hole, when holding charger or 
any other occasions.
 CAUTION:
To prevent the risk of fire or damage 
to the battery charger.
• Do not use power source from an 
engine generator.
• Do not cover vent holes on the 
charger and the battery pack.
• Unplug the charger when not in use.
