APPLICATION
(1) Cutting the hard boards types T9 and T7.
(ex. harditex, hardiflex, etc.)
(2) Cutting the gypsum board.
PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specified on the product
nameplate.
2. 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, which could cause
a serious accident.
3. 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.
4. Prepare a wooden workbench (Fig. 1)
Since the saw blade will extend beyond the lower
surface of the lumber, place the lumber on the
workbench prior to cutting. If a square block is
utilized as the workbench, adjust leveling to ensure
that it is properly stabilized. An unstable workbench
will result in hazardous operation.
CAUTION
To avoid possible accident, remains always ensure
that the portion of workpiece after cutting is securely
anchored or held in position.

CUTTING PROCEDURES
CAUTION
During use, when the body is out of condition or there
is unusual sound, please turn off a switch immediately.
During cutting, please do not pry the body or do not
push too much strongly. Please carry forward the
body calmly straightly.
It becomes the cause of an injury in response to
restitution. Moreover, while unreasonableness starts
a motor part, the life of saw blade is shortened.
Please do not carry out usage which made saw blade
facing up and sideways.
It becomes the cause of an injury.
Please use protection glasses.
Please use the protection implement of an ear.
Surely, the time of work discontinuation and after
work should turn off and put a switch, and should
pull out a lump plug from a power supply wall socket.
Be careful by rotating saw blade not to cut a code.
NOTE
Before beginning cutting, rotation of saw blade should
become the maximum high speed.
Extrusion fabrication cement building materials
should not cut 1 time of the cut depth with the speed
of 40 cm or less in 20 mm or less and 1 minute.
When using the cut depth, making it shallow, in order
that edge of a blade may open, dust-collecting power
declines.
1. The body (base) is carried on work piece and guide
slot of the base front part is united with a premarked
line.
When you do not incline, please follow large guide
slot as a guide, and when you incline (45°), follow
small guide slot as a guide (Fig. 5, Fig. 6, Fig. 7).
(It is the figure seen from the top)
Fig. 5
(When not inclined)
Fig. 6
(When inclined 45°)
Fig. 7
2. Saw blade turns on a switch in the state where work
piece cannot be touched.
This state is maintained until it carries forward the
body ahead slowly and finishes cutting it then.
For pulling and cleaning the skin, it advances straightly
with fixed speed.
MOUNTING AND DISMOUNTING THE SAW
BLADE
As for this body, saw blade is not attached to the body at
the time of factory shipments.
Please carry out attachment and removal of saw blade in
the following procedure in the case of use.
CAUTION
Surely, please turn off and put a switch in the case of
attachment and removal of saw blade, and pull out a
lump plug from a power supply wall socket.
It becomes the basis of the unexpected accident.
Attachment and detachment of a hexagonal flange
bolt should work with an attached box spanner.
If tools other than attachment are used, it will become
past [a bundle] and the shortage of bolting, and will
become the cause of an injury.
