Safety tips to know before purchasing a Rotary Saw

Rotary saws have been an important part of the firefighter’s tool cadre for many years. Today, most departments carry a variety of power saws including, but not limited to circular or rotary saws, chainsaws, and reciprocating saws.
We now see diversity in the types of rotary saws available for firefighting and rescue work. That selection includes petroleum power, two-stroke engines; electric-powered saws; electric-power with vacuum system; and electric-power with wet-cutting kit.

What is a Rotary saw?

A Rotary saw is a power-saw using a toothed or abrasive disc or blade to cut different materials using a rotary motion spinning around an arbor.
Rotary saws are the saw of choice when the task demands high cutting-blade speeds in order to get through materials like concrete, cinder block, asphalt, stone masonry, cast iron, aluminum … you get the picture — hard stuff.
Rotary saws are powerful hand tools that should be operated only by trained and qualified workers. Using rotary saws without being trained or flouting the rules can lead to serious or fatal injuries.

Hazards faced when using a Rotary Saw

Kickbacks: When a blade “catches” the stock and throws it back toward the operator, this is called a kickback. Kickbacks happen when the blade height is incorrect or if the blade has not been properly maintained. They also are more likely to occur when ripping rather than crosscutting. “Kickbacks also can occur if safeguards are not used or if poor-quality lumber is cut.

Point of operation: Injuries can occur if an operator’s hands slip while cutting or if they’re too close to the blade during cutting. To help prevent these injuries, make sure hands are out of the line of the cut.

Flying hazards: Operating a rotary saw can cause wood chips, broken saw teeth and splinters to be thrown from the blade and toward anyone nearby. Help prevent flying particles by removing cracked saw blades from service right away.

Safety tips
1. Using anti-kickback fingers to hold down stock.

2. Using the correct blade for the cutting action. For example, don’t use a crosscut blade for ripping.

3. Operating the saw at the manufacturer’s recommended speed.

4. Keeping the blade sharp.

5. Leaving enough clearance space for stock.

6. Supporting all parts of the stock, including the cut and uncut ends, scrap and fin.

7. Properly start the saw and get the engine up to its normal operating temperature by running at idle speed for two minutes.

8. Increase the engine speed to it maximum rpms for 30 seconds.

9. Bring the engine speed back to idle for no more than 30 seconds.
