and-held rotary power saws

are used frequently to cut

openings in masonry walls

and in demolition work and some-

times to cut brick or block for new

walls. Because they are portable

and usually don’t require water,

these saws come in handy when-

ever a quick cut through masonry

is needed. Before selecting from

among the many available mod-

els, consider these questions:

What kind of power is

available onsite?

Rotary power saws come in

gas-, air-, electric- or hydraulic-

powered designs. Gas saws are

themost mobile since they aren’t

tethered to an electric, air or hy-

draulic power source. However,

they create exhaust fumes, which

can be hazardous indoors or in

poorlyventilated, confinedspaces.

If not well-shielded, their mufflers

can cause operator burns, and if

they’re not well-designed or well-

maintained, the dust from cutting

can destroy the carburetor and

engine before the cutting blades

wear out.

To avoid this problem, the bet-

ter gas-powered models have so-

phisticated methods for filtering

air. Several saws described here

have multistage filtering systems.

Somealsohave specially designed

carburetors that maintain a con-

stant fuel:air ratio even when the

filter becomes partially clogged.
