5 IMPORTANT SAFETY INSTRUCTIONS
5.5 Fueling Instructions
Fuel
WARNING
￭ Gasoline and its vapors are extremely flammable. Your
STIHL blower uses an oil-gasoline mixture for 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 blower.
– Note that combustible fuel vapor may
escape from the fuel system.
Pick a Safe Location for Fueling
WARNING
￭ To reduce the risk of fire and explosion while fueling:
– Always remove the blower from the
operator's back and place it on the
ground before attempting to fuel the
blower.
– Fuel your blower in a well-ventilated
area, outdoors away from flames, pilot
lights, heaters, electric motors, and other
sources of ignition. Vapors can be
ignited by a spark or flame many feet
away.
– Select bare ground for fueling and move
at least 10 ft. (3 m) from the fueling spot
before starting the engine.
– Wipe off any spilled fuel before starting
your blower.
– Take care not to get fuel on your
clothing. If this happens, change your
clothing immediately.
Allow the Blower to Cool Before Removing the Fuel Cap
WARNING
￭ Gasoline vapor pressure may build up inside the fuel tank.
The amount of pressure depends on a number of factors,
such as the fuel used, altitude, and temperature. To
reduce the risk of burns and other personal injury from
escaping gas, vapor and fumes:
– Always shut off the engine and allow it to cool before
removing the fuel cap.
￭ The engine is air cooled. When it is shut off, cooling air is
no longer drawn across the cylinder and engine
temperatures will rise for several minutes before starting
to cool. In hot environments, cooling will take longer. To
reduce the risk of burns and other personal injury from
escaping gas vapor and fumes:
– Allow the blower to cool. If you need to refuel before
completing a job, turn off the machine and allow the
engine to cool before opening the fuel tank.
Fuel Spraying or "Geysering"
WARNING
￭ Removing the cap on a pressurized fuel tank can result in
gasoline, vapors and fumes being forcefully sprayed out
from the fuel tank in all directions. The escaping gasoline,
vapors or fumes can cause serious personal injury,
including fire and burn injury, or property damage.
￭ Sometimes also referred to as “fuel geysering,” fuel
spraying is an expulsion of fuel, vapors and fumes which
can occur in hot conditions, or when the engine is hot, and
the tank is opened without allowing the blower to cool
adequately. It is more likely to occur when the fuel tank is
half full or more.
￭ Pressure is caused by fuel and heat and can occur even if
the engine has not been running. When gasoline in the
fuel tank is heated (by ambient temperatures, heat from
the engine, or other sources), vapor pressure will increase
inside the fuel tank.
8
0458-459-8221-C
5 IMPORTANT SAFETY INSTRUCTIONS
English
￭ Some blends of gasoline, particularly winter blends, may
cause tanks to pressurize more quickly or create greater
pressure. At higher altitudes, fuel tank pressurization is
more likely.
How to Avoid Fuel Spraying
WARNING
￭ Removing the fuel cap on a pressurized tank can result in
gasoline, vapors and fumes being forcefully sprayed out
from the fuel tank in all directions. To reduce the risk of
burns, serious injuries or property damage from fuel
spraying:
– Follow the fueling instructions in this chapter.
– Always assume your fuel tank is pressurized.
– Allow the blower to cool before removing the fuel
cap.
– If you need to refuel before completing a job, turn off
the machine and allow the engine to cool before
removing the fuel cap. In hot environments, cooling
will take longer. The engine is air cooled. When it is
shut off, cooling air is no longer drawn across the
cylinder and the engine temperature will rise for
several minutes before starting to cool.
￭ After the blower has cooled appropriately, follow the
safety instructions in this chapter for removing the cap.
– Never remove the cap by turning it directly to the
open position.
– First check for residual pressure by slowly turning
the cap approximately 1/2 turn counter-clockwise.
– The cap should be held in place by the threads while
allowing residual vapor/pressure to be relieved.
– Once any residual pressure has been relieved, turn
the cap until it can be removed from the tank
opening.
– Use only good quality fuel that is appropriate for the
season (summer v. winter blends). Some blends of
gasoline, particularly winter blends, are more volatile
and can contribute to fuel spraying.
Removing the Threaded Fuel Filler Cap
WARNING
￭
￭ After allowing the blower to cool, remove the fuel filler cap
slowly and carefully to allow any remaining pressure buildup in the tank to release:
– While maintaining steady, downward pressure,
slowly turn the cap approximately 1/2 turn counter-
clockwise.
– If any significant venting occurs, immediately re-seal
the tank by turning the cap clockwise to the closed
position. Allow the blower to cool further before
attempting to open the tank.
– Turn the cap to the open position only after the
contents of the tank are no longer under pressure.
– Never remove the cap by turning it directly to the
open position without first allowing the blower to cool
adequately and then releasing any residual pressure
by slowly turning it approximately 1/2 turn counter-
clockwise.
– Never attempt to remove the cap while the engine is
still hot or running.

5 IMPORTANT SAFETY INSTRUCTIONS
Installing the Threaded Fuel Filler Cap
WARNING
￭
￭ An improperly tightened fuel filler cap can loosen or come
off and spill quantities of fuel. To reduce the risk of fuel
spillage and fire from an improperly installed fuel cap,
correctly position and tighten the cap by hand with as
much force as possible.
Damaged or Broken Cap
WARNING
￭ If your fuel cap does not tighten properly, it may be
damaged or broken. Stop using the blower and take it to
your authorized STIHL dealer for repair.
Vapor Lock
WARNING
￭ Vapor lock occurs when fuel in the fuel line or carburetor
vaporizes, causing bubbles to block the free flow of liquid
fuel into the carburetor.
￭ Vapor lock cannot be relieved or affected by opening the
fuel tank. Removing the fuel filler cap without first allowing
the blower to cool adequately can result in fuel spraying.
Always follow the instructions in this section when
removing the fuel cap.
￭ To relieve vapor lock:
– Press the manual fuel pump bulb at least 20 to 30
times – even if the bulb is already filled with fuel – to
clear the vapor and send liquid fuel into the
carburetor. Then start the blower. For specific
starting instructions, see the appropriate section of
your instruction manual.
– If the manual fuel pump bulb will not be filled, place
the Choke Knob to the position and pull the
starter cord until the engine runs.
– If your blower will not restart, or if vapor lock occurs
again, the blower is being used in conditions too
extreme for the fuel being used. Discontinue use and
0000-GXX-B945-A0
let the engine cool completely before attempting to
start the blower.
– Using good quality, fresh fuel (stored less than 30
days) also can help reduce the occurrence of vapor
lock.
5.6 Starting
WARNING
￭ To reduce the risk of burns and other personal injury from
escaping gas vapor and fumes:
– Move at least 10 ft. (3 m) from the fueling spot before
starting the engine.
– Start your blower only outdoors.
￭ To reduce the risk of serious or fatal injuries to the
operator or bystanders from loss of control:
– Start the blower only as described in the "Starting"
chapter in this manual, @ 11.
– When you pull the starter grip, do not wrap the
starter rope around your hand.
– Do not let the grip snap back. Guide the starter rope
to rewind it properly.
– Once the engine has started, immediately blip the
throttle trigger, which should cause the choke knob
to move to the run position and allow the engine to
slow down to idle.

10 Mixing Fuel and Refueling the Blower
English
10 Mixing Fuel and Refueling the Blower
10.1 Mixing Fuel
Information on Fuel
Your engine requires a mixture of high-quality gasoline and
2-cycle air cooled engine oil. This engine is certified to
operate on mid-grade unleaded gasoline with a minimum
octane rating of 89 and no more than 10 % ethanol and
2-cycle oil for air cooled engines at a mix ratio of 50:1.
If you mix the fuel yourself, STIHL recommends the following
2-cycle engine oils:
– STIHL HP Ultra 2-Cycle Engine Oil
NOTICE
Fuel with an octane rating below 89 may increase engine
temperatures. This, in turn, increases the risk of piston
seizure and damage to the engine. The chemical
composition of the fuel is also important.
NOTICE
Some fuel additives not only detrimentally affect elastomers
(carburetor diaphragms, oil seals, fuel lines, etc.), but
magnesium castings and catalytic converters as well. This
could cause running problems or damage the engine. For
this reason STIHL recommends that you use only quality
unleaded gasoline.
Information on Ethanol Content
Gasoline with an ethanol content of more than 10% can
cause running problems and major damage in engines and
should not be used. For further details, see
www.STIHLusa.com/ethanol.
The ethanol content in gasoline affects engine speed. It may
be necessary to readjust the carburetor if you use fuels with
varying ethanol content.
The idle speed and maximum speed of the engine change if
you switch to a fuel with a much higher or lower ethanol
content. This problem can be avoided by always using an
ethanol-free fuel or fuel with consistent ethanol levels.
STIHL MotoMix
STIHL MotoMix is ethanol-free, has a high octane rating and
ensures that you always use the right gasoline/oil mix ratio.
STIHL MotoMix uses STIHL HP Ultra 2-Cycle Engine Oil
suited for high performance engines. For further details, see
www.STIHLusa.com/ethanol.
STIHL recommends using MotoMix in your blower. If not
using MotoMix, use only STIHL HP Ultra 2-Cycle Engine Oil
or equivalent high quality 2-cycle engine oils that are
designed for use in air cooled 2-cycle engines.
The use of non-seasonal gasoline blends may increase the
potential for pressure to build in the fuel tank during
operation. For example, using a winter blend during the
summer will increase pressure in the fuel tank. Always use
gasoline blends appropriate to the season, altitude and
other environmental factors.
Do not use NMMA or TCW rated (2-cycle water cooled) mix
oils or other mix oils that state they are for use in both water
cooled and air cooled engines (e.g., outboard motors,
snowmobiles, chain saws, mopeds, etc.).
Mixing Fuel
WARNING
Take care when handling gasoline. Avoid direct contact with
the skin and avoid inhaling fuel vapor. Anytime you are filling
a container at the fuel pump, remove the container from your
vehicle and place it on the ground before filling. To reduce
the risk of sparks from static discharge and resulting fire
and/or explosion, do not fill fuel containers that are sitting in
or on a vehicle or trailer.
WARNING
Shaking fuel can cause pressure to build in the fuel
container. To reduce the risk of fire and severe personal
injury or property damage from fuel spraying, allow the fuel
container to sit for several minutes before opening. Open the
0458-459-8221-C
19
English
10 Mixing Fuel and Refueling the Blower
container slowly to release any residual pressures. Never
open the fuel container in the vicinity of any ignition source.
Read and follow all warnings and instructions that
accompany your fuel container.
To properly mix fuel:
► If not using STIHL MotoMix, only mix sufficient fuel for a
few days of work. Never mix more than a 30-day supply of
fuel.
► Store the fuel mix in an approved fuel container.
► Depending on the required amount of fuel, determine the
correct amounts of 2-cycle engine oil and gasoline in a mix
ratio of 50:1. Examples for fuel mixes:
– 1 US gals of gasoline: 2.6 oz. of 2-cycle engine oil
– 2.5 US gals of gasoline: 6.4 oz. of 2-cycle engine oil
– 5 US gals of gasoline: 12.8 oz. of 2-cycle engine oil
► When mixing, pour oil into the container first, and then add
gasoline. Close the container and shake it by hand to
ensure proper mix of oil and gasoline.
► Dispose of empty mixing-oil containers only at authorized
disposal locations.
10.2 Refueling the Blower
WARNING
Removing the fuel cap on a pressurized fuel tank can result
in gasoline, vapors and fumes being forcefully sprayed out
from the tank in all directions. The escaping gasoline, vapors
or fumes, sometimes referred to as fuel spraying or
“geysering,” can cause serious personal injury, including fire
and burn injury, or property damage, @ 5.5.
Spraying is more likely to occur when the fuel tank is half full
or more. Always follow the fueling instructions in this
manual:
– Treat every fuel tank as if it is pressurized, particularly
if it is half full or more.
– Always allow the blower to cool adequately before
attempting to open the fuel tank or refueling. This will
take longer in hot conditions.
– Never open the fuel tank while the engine is still hot or
running.
– Never open the fuel tank or re-fuel the blower near any
sparks, flames or other ignition sources.
– Pick the right fuel: use only good quality (89 octane or
higher), fresh fuel blended for the season.
– Vapor lock: do not remove the fuel cap in an effort to
relieve vapor lock. Removing the cap has no effect on
vapor lock.
– Be aware that fuel spraying is more likely at higher
altitudes.
Opening and Refueling
To refuel the blower:
► Shut off the engine, @ 12.1.
► Allow the blower to cool. Never attempt to remove the cap
while the engine is still hot or running.
► Position the blower on a level surface with the fuel filler
cap facing upwards.
► Clean the area around the fuel filler cap with a slightly
dampened cloth.
WARNING
Fuel spraying can occur when the engine is hot and the tank
is opened while under pressure. It can occur in hot
environments even if the engine has not been running.
