Although our C 6MFA/C 7MFA Circular Saws now available on the European market are highly evaluated as
reasonably priced, light-load products, there is also growing demand for less expensive and lighter circular saw
products. In order to expand the market share of our circular saw series products, we consequently released the
C 6SS/C 7SS Circular Saws in wider regions including Europe, as a low-priced series developed by balancing
price and performance.

Compact and lightweight design
The Models C 6SS and C 7SS adopt the highly evaluated
compact design of the C 6MFA/C 7MFA, and incorporate a
light-weight, highly rigid lower guard and a side handle
made of resin to reduce overall weight.
Power-plus heavy-duty motor
The cooling flow path is enhanced to increase power.
(For 230/240 V)
Sawdust rear-discharge type
(Dust collector installable)
A sawdust rear-discharge method is adopted to prevent
sawdust from accumulating on the work face. Simply
attaching an optional dust collector will ensure a clean
environment with minimal scattering of sawdust.
Blower function
The Models C 6SS and C 7SS come with the blower function to blow sawdust away using cooling air of the
motor.
Accurate and sturdy aluminum die-cast base
(Steel plate base available depending on destination)
Thanks to the sturdy aluminum die-cast base, the Models C 6SS and C 7SS can cut workpieces accurately,
resulting in smooth cut workpiece surfaces.
Double-insulated construction
Grounding is not required due to the double-insulated construction.
Refer to the Technical Data and Service Manuals for current models.
