CONCEPTION AND MAIN APPLICATIONS 499
Model 2106 is a portable band saw suitable for cutting pipe and light
weight steel, etc.,
235
and it's belief benefits are:
Light weight and wide range of cutting capacities from 115mm to large
230
diameter material.

Features and benefits
1. Wide range of cutting capacity up to 4 inch pipe (outer diameter 115mm)
2. 5.5kg light weight improves workability.
3. Speed can be changed by two steps and peripheral velocity is variable depending on material.
4. Tension load to the blade can be easily set by the lever and the blade will be replaced quickly.
5. Large front grip and comfortable handle shape improve operability. Cab-tire cord is coming out from the side so as not
to disturb workability.
6. Optional stand enables the machine to be fixed.

Repair
1. Replacement of armature
(1) Remove carbon brush, four hex. socket bolts that
secures motor housing, and two pan-head screw
that fixes handle on the frame.
(2) Remove motor housing together with handle from
the gear housing, and armature can be removed.
(3) Assemble with a reverse order of disassembly. Do
not forget to attach baffle plate.
