FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Selecting the cutting action (Fig. 1)
This tool can be operated with an orbital or a straight line
(up and down) cutting action. The orbital cutting action
thrusts the blade forward on the cutting stroke and
greatly increases cutting speed.
To change the cutting action, just turn the cutting action
changing lever to the desired cutting action position.
Refer to the table to select the appropriate cutting action.

ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing or removing saw blade (Fig. 3 & 4)
CAUTION:
• Always clean out all chips or foreign matter adhering to
the blade and/or blade holder. Failure to do so may
cause insufficient tightening of the blade, resulting in a
serious personal injury.
• Do not touch the blade or the workpiece immediately
after operation; they may be extremely hot and could
burn your skin.
• Always secure the blade firmly. Insufficient tightening of
the blade may cause blade breakage or serious per-
sonal 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.
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. 5)
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 blade breakage, resulting in a seri-
ous injury.
• Advance the tool very slowly when cutting curves or
scrolling. Forcing the tool may cause a slanted cutting
surface and blade breakage.
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 for-
ward along the previously marked cutting line. (Fig. 6)
