Brush cutters can be dangerous, so follow this safety checklist whenever you're using a power tool to trim, prune, or cut thick grass or tree limbs: -- Wear protective goggles or face shields, and long pants, gloves, and boots.  -- Don’t wear loose clothing or long jewelry. -- Do tie your hair back to avoid it getting caught in the brush cutter. -- Use a brush cutter with a long shaft and deck guard to keep your face and body protected fr om the blade and flying debris.  -- Wear a shoulder strap or harness to lessen the brush cutter’s weight on your arms, lowering fatigue and preventing injury. -- Pay attention while adding or mixing fuel with a gas-powered brush cutter, and always make sure the engine has stopped before removing the fuel cap. -- The final and most important safety tip: If you feel you’re unable to use a brush cutter properly, hire a landscaping professional for your safety and the safety of others.
