PRIOR TO OPERATION

1. This product has double insulation. However, to
avoid electric shocks, be sure to use a power
source that is equipped with a circuit breaker to
cope with power leakage and sudden surges.
2. Power source
Ensure that the power source to be utilized
conforms to the power requirements specified on
the product nameplate.
3. Power switch
Ensure that the power switch is in the OFF position.
If the plug is connected to a receptacle while the
power switch is in the ON position, the power tool
will start operating immediately, inviting serious
accident.

steel materials.
4. Extension cord
When the work area is removed from the power
source, use an extension cord of sufficient thickness
and rated capacity. The extension cord should be
kept as short as practicable.
5. Preparing a wooden work bench

In situations like this, it is safer to make sure that
the material is firmly secured in place using a vise
so that both hands can be used to operate the
metal cutter.
If the piece to be cut off is large in size, care must
be taken to see that the weight of the piece being
cut off does not press on the saw blade. To
prevent the saw blade from being caught between
the two pieces, the piece being cut off should be
supported using a stable bench or braced in place
using wooden supports.
If separate wooden supports are to be used to
support the piece being cut off, when cutting at
a work bench, they should be positioned on a flat
surface and fixed in place. It is dangerous to allow
the work bench to wobble or shift position while
cutting materials with the metal cutter.
6. Checking to see that the tipped saw blade is
attached firmly in position
Always check to see that the tipped saw blade
is attached firmly in position. For details, see Page
7: "Attached and removing the tipped saw blade".
7. Check the lever to see that is properly tightened.
Insufficient tightening of the cutting adjustment
lever may cause personal injury (See Fig. 2).
Be sure to check that it is firmly tightened.
8. Attaching the side handle
Attach the side handle by screwing it in place in
the socket located on the gear cover. (See
Fig. 1)
The outer edge of the
tipped saw blade projects
from the bottom of the
work piece being cut.
Vise
Therefore, the material
should be placed on a work
bench when cutting.
Work
In addition, care should be
bench
taken to see that the tipped
saw blade and protective
cover do not come into
contact with the surface
Work piece
below the work piece (e.g.,
Projection
the surface of the work
distance of
bench or the ground, floor,
the tipped
etc.). To make sure that this
saw blade
does not happen, the work
piece (material to be cut)
should be at a height above
the surface below the work
piece that is equal to at
l e a s t t h r e e t i m e s t h e
distance (width) that the
blade projects below the
bottom of the work piece.
