and a circular saw blade (3). The trigger switch(4) is
built into the handle. Saws vary in size and design
depending on the nature of the task. There are many
applications for this tool. Typical uses would be cutting
studding to length, cutting off end boards, preparing
trim, or ripping boards and planks.
ELECTRIC CHAIN SAW
The electrically driven chain saw is a portable power
saw with the teeth (1) arranged on a flexible steel chain-
like belt (2). It has a pistol-like grip (3) and bar frame (4)
above the motor housing (5) for holding and guiding.
Unlike the gasoline-powered chain saw, the electric
chain saw is designed for lighter work such as tree
trimming and cutting small logs and timber.
PORTABLE ELECTRIC DISK SANDER
The portable electric disk sander is an electrically driven
tool with a spindle (1) at the front end for holding circular
attachments (2). Various types of attachments can be
fastened to the end of the projecting spindle. The rear
end of the sander's housing tapers to form a guiding
handle (3). To provide additional control, a second
handle (4) is attached to the side of the housing. The
portable electric disk sander with its many attachments
can be used for a variety of tasks. Heavy-duty sanding,
grinding, wire brushing, buffing, and planing are some of
the possible applications.
