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.

Assembly Diagram for C 7SS

-1-

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.
