Fuel

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

!Warning!

Gasoline is an extremely flammable fuel. If spilled and ignited by a spark or

other ignition source, it can cause fire and serious burn injury or property

damage. Use extreme caution when handling gasoline or fuel mix.

Do not smoke or bring any fire or flame near the fuel or the power tool. Note that combustible fuel vapor may escape from the fuel system.

Fueling Instructions

!Warning!

Fuel your power tool in well-ventilated areas, outdoors. Always shut off the engine and allow it to cool before refueling. Gasoline vapor pressure may build up inside the fuel tank depending on the fuel used, the weather conditions and the tank venting system.

In order to reduce the risk of burns and other personal injury from escaping gas vapor and fumes, remove the fuel filler cap on your power tool carefully so as to allow any pressure build-up in the tank to release slowly. Never remove the fuel filler cap while the engine is running.

Select bare ground for fueling and move at least 10 feet (3 m) from the fueling spot before starting the engine. Wipe off any spilled fuel before starting your machine.

!Warning!

Check for fuel leakage while refueling and during operation. If fuel leakage is found, do not start or run the engine until the leak is fixed and any spilled fuel has been wiped away. Take care not to get fuel on your clothing. If this happens, change your clothing immediately.

Different models may be equipped with different fuel caps.

Cap with grip !Warning!

In order to reduce the risk of fuel spillage and fire from an improperly tightened fuel cap, correctly position and tighten the fuel cap in the fuel tank opening.

To do this with this STIHL

cap, raise the grip on the

top of the cap until it is

upright at a 90° angle. Insert the cap in the fuel tank opening with the

triangular marks on the grip of the cap and on the fuel tank opening lining up. Using the grip, turn the cap firmly clockwise as far as it will go (approx. a quarter turn).

Fold the grip flush with the top of the cap. If the grip

does not lie completely flush with the cap and the detent on the grip does not fit in the

corresponding recess in the filler opening, the cap is not properly seated and tightened and you must repeat the above steps.

Screw cap !Warning!

Unit vibrations can cause an improperly tightened fuel filler cap to loosen or come off and spill quantities of fuel. In order to reduce the risk of fuel spillage and fire, tighten the fuel filler cap by hand as securely as possible.

The screwdriver end of the STIHL combination wrench or other similar

tool can be used as an aid in tightening slotted fuel filler caps.

See "Fueling" chapter in your instruction manual.
