Chainsaw safety
By: Sade Sturdivant
Kick back
Kickback is the term to describe the unexpected upward motion of the guide bar.Kickback occurs when the end portion of the nose of the bar (the kickback zone) strikes an object and the chain momentarily snags, or is pinched.
Tips for reducing kick back
- Cut only one piece at a time.
- Run the saw at full power when cutting.
- Keep the chain sharpened to specifications (e.g. correct depth and angle).
- Match chain and bar for exact pitch and gauge.
PPE
Personal protective equipment (PPE) refers to protective clothes,goggles,helmets, or other garments or equipment designed to protect the wearer's body from injury.Chainsaw protection (especially a helmet with face guard, hearing protection, kevlar chaps, anti-vibration gloves, and chainsaw safety boots).

likely injuries w/ a chainsaw
- According to the U.S. Consumer Products Safety Commission there were over 28,500 chain saw injuries in 1999. More than 36% were injuries to the legs and knees
Fueling cainsaw
2-stroke engines use only 2 strokes during the firing cycle, rather than the 4 strokes used by conventional 4-stroke engines. The process allows for the combustion stroke to function simultaneously with the exhaust, while the compression stroke performs double duty to include the intake function. This process creates double the power of a 4-stroke engine, making the 2-stroke engine ideal for chainsaws and other lightweight applications. By adding oil to the fuel in a prescribed ratio, the fuel acts as a lubricating agent for the moving internal parts of the engine.

Transporting the chainsaw
- Shut off the chain saw motor before setting it down or carrying it for more than a very short distance. It is extremely dangerous to carry a chain saw when the engine is running.
- Let the chain saw cool before transporting.
- Use a scabbard or bar guard to cover the chain when carrying or transporting a chain saw.
- Carry the chain saw with the bar pointed behind you. Ensure the scabbard is on and the muffler is away from the body.
