THE USE OF THE BLOWER 

Transport

Always turn off the engine before putting 
down blower. When transporting your 
unit in a vehicle, properly secure it to 
prevent turnover, fuel spillage and 
damage to the machine.

Adjust carrying harness to suit your size 
before starting work.

!

Warning!

Before starting work, always inspect the 
rubber buffers which connect the engine 
to the pack frame. If the buffers are torn 
or damaged, they should be replaced by 
your STIHL dealer. Failure of one or 
more buffers may cause the engine or 
fuel tank to hit or rub against other parts, 
and may lead to serious injury from 
increased vibrations or from fire as the 
result of fuel leakage.

Fueling 

This STIHL unit uses an oil-gasoline 
mixture for fuel (see the chapter on 
"Fuel" of your owner`s manual). 

!

Warning!

Gasoline is an extremely 
flammable fuel. If spilled 
or ignited by a spark or 
other ignition source, it 
can cause fire and serious 
burn injury or property 
damage.

!

Warning!

To reduce the risk of serious injury from 
burns, never attempt to refuel the unit 
until it has been completely removed 
from the operator.

Use extreme caution when handling 
gasoline or fuel mix. 
Do not smoke or bring any fire or flame 
near the fuel.

Fueling instructions

Fuel your machine in well-ventilated 
areas, outdoors only. Always shut off the 
engine and allow it to cool before 
refueling. Relieve fuel tank pressure by 
loosening fuel cap slowly. Never remove 
fuel filler cap while engine is running.

Select bare ground for fueling and move 
at least 10 feet (3 m) from the fueling 
spot before starting the engine. Avoid 
spilling of fuel or oil. Wipe off any spilled 
fuel before starting your blower and 
check for leakage.

Always tighten fuel filler cap securely 
after fueling.

!

Warning!

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

Always store gasoline in a container 
approved for flammable liquids.

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).
