ASSEMBLY
CAUTION:
Always be sure that the tool is
switched off and unplugged before carrying out
any work on the tool.
Installing or removing jig saw blade
CAUTION:
Always clean out all chips or for-
eign matter adhering to the jig saw blade and/or
blade holder. Failure to do so may cause insufficient
tightening of the blade, resulting in a serious personal
injury.
CAUTION:
Do not touch the jig saw blade or
the workpiece immediately after operation. They
may be extremely hot and could burn your skin.
CAUTION:
Always secure the jig saw blade
firmly. Insufficient tightening of the blade may cause
blade breakage or serious personal injury.
CAUTION:
Use only B type jig saw blades.
Using blades other than B type causes insufficient
tightening of the blade, resulting in a serious personal
injury.
To install the jig saw blade, loosen the bolt counter-
clockwise on the jig saw blade holder with the hex
wrench.
► Fig.3: 1. Jig saw blade holder 2. Bolt 3. Hex wrench
With the blade teeth facing forward, insert the jig saw
blade into the jig saw blade holder as far as it will go.
Make sure that the back edge of the blade fits into the
roller. Then tighten the bolt clockwise to secure the blade.

To remove the jig saw blade, follow the installation
procedure in reverse.
NOTE: Occasionally lubricate the roller.
Hex wrench storage
► Fig.5: 1. Hook 2. Hex wrench
When not in use, store the hex wrench as shown in the
figure to keep it from being lost.
OPERATION
CAUTION:
Always hold the base flush with
the workpiece. Failure to do so may cause jig saw
blade breakage, resulting in a serious injury.
CAUTION:
Advance the tool very slowly when
cutting curves or scrolling. Forcing the tool may
cause a slanted cutting surface and jig saw blade
breakage.
► Fig.6: 1. Cutting line 2. Base
Turn the tool on without the jig saw blade making any
contact and wait until the blade attains full speed. Then
rest the base flat on the workpiece and gently move the
tool forward along the previously marked cutting line.
Bevel cutting
CAUTION:
Always be sure that the tool is
switched off and unplugged before tilting the
base.
CAUTION:
Raise the dust cover all the way
before making bevel cuts.
With the base tilted, you can make bevel cuts at any
angle between 0° and 45° (left or right).
► Fig.7
Loosen the bolt on the back of the base with the hex
wrench. Move the base so that the bolt is positioned in
the center of the cross-shaped slot in the base.
► Fig.8: 1. Hex wrench 2. Bolt 3. Base
Tilt the base until the desired bevel angle is obtained.
The edge of the motor housing indicates the bevel
angle by graduations. Then tighten the bolt to secure
the base.
► Fig.9: 1. Edge 2. Graduation
Front flush cuts
► Fig.10: 1. Hex wrench 2. Bolt 3. Base
Loosen the bolt on the back of the base with the hex
wrench and slide the base all the way back. Then
tighten the bolt to secure the base.
Cutouts
Cutouts can be made with either of two methods
"Boring a starting hole" or "Plunge cutting".
Boring a starting hole
► Fig.11
For internal cutouts without a lead-in cut from an edge,
pre-drill a starting hole 12 mm or more in diameter.
Insert the jig saw blade into this hole to start your cut.
Plunge cutting
► Fig.12
You need not bore a starting hole or make a lead-in cut
if you carefully do as follows.
1. Tilt the tool up on the front edge of the base with
the jig saw blade point positioned just above the work-
piece surface.
2. Apply pressure to the tool so that the front edge of
the base will not move when you switch on the tool and
gently lower the back end of the tool slowly.
3. As the jig saw blade pierces the workpiece, slowly
lower the base of the tool down onto the workpiece
surface.
4. Complete the cut in the normal manner.
Finishing edges
► Fig.13
To trim edges or make dimensional adjustments, run the
jig saw blade lightly along the cut edges.
