FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Adjusting the shoe (Fig. 1 & 2)
CAUTION:
• Secure the shoe firmly after reposition the shoe.
When the blade loses its cutting efficiency in one place
along its cutting edge, reposition the shoe to utilize a
sharp, unused portion of its cutting edge. This will help to
lengthen the life of the blade.
To reposition the shoe, peel off the cover and loosen the
clamping screw with the hex wrench as shown in the fig-
ure.
Slide the shoe forward or back to the desired position,
then tighten the clamping screw to firmly secure the shoe.
(Fig. 3)
Switch action (Fig. 4)
CAUTION:
• Before plugging in the tool, always check to see that
the switch lever actuates properly and returns to the
"OFF" position when released.
To start the tool, simply pull the switch lever. Tool speed is
increased by increasing pressure on the switch lever.
Release the switch lever to stop.
Speed adjusting dial (Fig. 5)
The maximum strokes per minute with the switch lever
being fully depressed can be adjusted just by turning the
speed adjusting dial.
Turn the speed adjusting dial clockwise for higher speed,
and counterclockwise for lower speed.
Lighting up the lamps (Fig. 6)
CAUTION:
• Do not look in the light or see the source of light
directly.
To turn on the lamp, pull the switch lever. Release the
switch lever to turn it off.
NOTE:
• Use a dry cloth to wipe the dirt off the lens of lamp. Be
careful not to scratch the lens of lamp, or it may lower
the illumination.
• Do not use thinner or gasoline to clean the lamp. Such
solvents may damage it.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.

Installing or removing the saw blade
CAUTION:
• Always clean out all chips or foreign matter adhering to
the blade and/or blade clamp. Failure to do so may
cause insufficient tightening of the blade, resulting in a
serious injury.
• Do not touch the blade or the workpiece immediately
after operation; they may be extremely hot and could
burn your skin.
• Tighten the saw blade securely. Failure to do so may
cause a serious injury.
• When you remove the saw blade, be careful not to hurt
your fingers with the top of the blade or the tips of work-
piece.
• Use B type saw blade only. Never use other type
blade. Failure to do so may cause a serious injury.
To install the saw blade, push the holder cover to rotate
the blade clamp to the released position as shown in the
figure. (Fig. 7)
Keeping that situation, insert the saw blade into the blade
clamp as far as the two protrusions of the blade can not
be seen. (Fig. 8)
Release the holder cover. The blade clamp will rotate to
its fixed position to secure the blade.
After installing, always make sure that the blade is
securely held in place by trying to pull it out. (Fig. 9)
To remove the blade, push the holder cover to rotate the
blade clamp to the released position, then pull the saw
blade out. (Fig. 10)
OPERATION (FIG. 11)
CAUTION:
• Always press the shoe firmly against the workpiece
during operation. If the shoe is held away from the
workpiece during operation, strong vibration and/or
twisting will be produced, causing the blade to snap
dangerously.
• Always wear gloves to protect your hands from hot fly-
ing chips when cutting metal.
• Be sure to always wear suitable eye protection which
conforms with current national standards.
• Always use a suitable coolant (cutting oil) when cutting
metal. Failure to do so will cause premature blade
wear.
• Hold the tool firmly with one hand on front but never
beyond the collar and the other on the rear housing as
shown in the figure. Failure to do so will cause a seri-
ous injury.
Press the shoe firmly against the workpiece. Do not allow
the tool to bounce. Bring the blade into light contact with
the workpiece. First, make a pilot groove using a slower
speed. Then use a faster speed to continue cutting. (Fig.
