ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
the battery cartridge is removed before carrying
out any work on the tool.
Installing or removing saw blade
► Fig.4: 1. Blade holder 2. Bolt 3. Hex wrench
CAUTION:
• Always clean out all chips or foreign matter
adhering to the blade and/or blade holder.
Failure to do so may cause insufficient tighten-
ing of the blade, resulting in a serious personal
injury.
• Do not touch the blade or the workpiece imme-
diately after operation; they may be extremely
hot and could burn your skin.
• Always secure the blade firmly. Insufficient tight-
ening of the blade may cause blade breakage or
serious personal injury.
• Use only B type blades. Using blades other than
B type blades causes insufficient tightening of
the blade, resulting in a serious personal injury.
► Fig.5: 1. Bolt 2. Blade 3. Roller
To install the blade, loosen the bolt counterclockwise on
the blade holder with the hex wrench.
With the blade teeth facing forward, insert the blade into
the 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 blade, follow the installation procedure
in reverse.
NOTE:
• Occasionally lubricate the roller.
Hex wrench storage
► Fig.6: 1. Hook 2. Hex wrench
When not in use, store the hex wrench as shown in the
figure to keep it from being lost.
First, insert the hex wrench into the hole. Then push it
into the hook until it locked.
Dust cover
► Fig.7: 1. Dust cover
CAUTION:
• Always wear safety goggles even when operat-
ing the tool with the dust cover lowered.
Lower the dust cover to prevent chips from flying.
However, when making bevel cuts, raise it all the way.
OPERATION
CAUTION:
• Always hold the base flush with the workpiece.
Failure to do so may cause blade breakage,
resulting in a serious injury.
• Advance the tool very slowly when cutting
curves or scrolling. Forcing the tool may cause a
slanted cutting surface and blade breakage.
► Fig.8: 1. Cutting line 2. Base
Turn the tool on without the 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
► Fig.9
CAUTION:
• Always be sure that the tool is switched off and
the battery cartridge is removed before tilting
the base.
• Raise the dust cover all the way before making
bevel cuts.
► Fig.10: 1. Hex wrench 2. Bolt 3. Base
With the base tilted, you can make bevel cuts at any
angle between 0° and 45° (left or right).
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.11: 1. Edge 2. Graduation
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.
Front flush cuts
► Fig.12: 1. Bolt 2. Hex wrench 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 A or B.
A) Boring a starting hole
► Fig.13: 1. Starting hole
For internal cutouts without a lead-in cut from an
edge, pre-drill a starting hole 12 mm or more in
diameter. Insert the blade into this hole to start
your cut.
