APPLICATIONS

For cutting various types of soft steel materials
such as flat steel strips, pipe, steel channels ("C"
channels, "L" angles, etc.).
CAUTION
Cannot be used for cutting tempered steel
materials.

PRIOR TO OPERATION

1. Power source
Ensure that the power source to be utilized
conforms to the power source requirements
specified on the product nameplate.
2. Power switch
Ensure that the switch is in the OFF position. If the
plug is connected to a receptacle while the switch
is in the ON position, the power tool will start
operating immediately and can cause serious injury.
3. Extension cord
When the work area is far away from the power
source, use an extension cord of sufficient
thickness and rated capacity. The extension cord
should be kept as short as practicable.
WARNING:
Damaged cord must be replaced or
repaired.
4. Check the receptacle
If the receptacle only loosely accepts the plug, the
receptacle must be repaired. Contact a licensed
electrician to make appropriate repairs.
If such a faulty receptacle is used, it may cause
overheating, resulting in a serious hazard.

ASSEMBLY AND OPERATION

Work piece to
be cut
Work
Vise
bench
Projection distance of
the tipped saw blade
The outer edge of the tipped saw blade projects
from the bottom of the work piece being cut.
Therefore, the material should be placed on a work
bench when cutting.
In addition, care should be taken to see that the
tipped saw blade and protective cover do not come
into contact with the surface below the work piece
(e.g., the surface of the work bench or the ground,
floor, etc.). To make sure that this 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 least three times the distance (width)
that the blade projects below the bottom of the
work piece.
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
cutting saw.
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
10: "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.
Be sure to check that it is firmly tightened.
8. Check to see whether the protective cover moves.
CAUTION
Do not fasten the protective cover
permanently in one position. Make sure that
it can move smoothly. Leaving the tipped saw
blade exposed can result in accidents.
The protective cover is used to prevent the body
of the user from coming into contact with tipped
saw blade. Be sure that the protective cover can
be moved into place and is covering the blade. If
for any reason, the protective cover will not move
into position to cover the blade, discontinue the
use of the metal cutter. Please contact an
Authorized Hitachi Service Center for repair.
