Good footing is very important. Wear sturdy boots with nonslip soles. Steel-toed safety boots suitable for climbing in trees are recommended.

Never operate your power tool unless wearing goggles or properly fitted protective glasses with adequate top and side protection complying with ANSI Z 87.1 (or your applicable national standard).

Always wear gloves when handling the machine and the cutting tool. Heavy-duty, nonslip gloves improve your grip and help to protect your hands.

Wear an approved safety hard hat to reduce the risk of injury to your head.

Chain saw noise may damage your hearing. Wear sound barriers (ear plugs or ear mufflers) to help protect your hearing. Continual and regular users should have their hearing checked regularly.

Be particularly alert and cautious when wearing hearing protection because your ability to hear warnings (shouts, alarms, etc.) is restricted.

Use proper equipment at all times to protect yourself from falling.

Any crew member in the cutting area should also wear proper protective clothing, especially hard hats, to protect their heads.

By hand: When carrying your saw by hand, the engine must be switched off and the saw must be in the proper position. Grip the top handle and place the muffler away from the body. The chain guard (scabbard) should be over the chain and guide bar, which should point backwards.

By vehicle: When transporting in a vehicle, keep chain and bar covered with the chain guard. Properly secure your saw to prevent turnover, fuel spillage and damage to the saw.

Fuel

Your STIHL power tool uses an oil- gasoline mixture for fuel (see chapter on "Fuel" of your instruction manual).
