WARNING
Note the arrows indicating the direction of rota‐
tion on diamond abrasive wheels.
► Fit the front thrust washer (3). The catches of
the front thrust washer (3) must engage in the
shaft grooves
► Screw in the hexagon bolt and tighten it with
the combination wrench – if using a torque
wrench, refer to the "Specifications" for the
tightening torque
► Draw the locking pin out of the V-belt guard
WARNING
Never use two abrasive wheels at the same time.
The uneven wear creates a risk of breaking and
an injury hazard!
11 Fuel
This engine is certified to operate on unleaded
gasoline and with the mix ratio 50:1.
Your engine requires a mixture of high-quality
premium gasoline and high-quality two-stroke
air-cooled engine oil.
Use premium branded unleaded gasoline with a
minimum octane rating of 89 (R+M)/2.
Fuel with a lower octane rating may result in pre‐
ignition (causing "pinging") which is accompa‐
nied by an increase in engine temperature. This,
in turn, increases the risk of the piston seizure
and damage to the engine.
The chemical composition of the fuel is also
important. Some fuel additives not only detrimen‐
tally affect elastomers (oil seals, fuel lines etc.),
but magnesium castings as well. This could
cause running problems or even damage the
engine. For this reason it is essential that you
use only high-quality fuels!
Fuels with different percentages of ethanol are
being offered. Ethanol can affect the running
behaviour of the engine and increase the risk of
lean seizure.
Engines equipped with STIHL Injection can be
run on gasoline with an ethanol content of up to
25% (E25).
Use only STIHL two-stroke engine oil or equiva‐
lent high-quality two-stroke air-cooled engine oils
for mixing.
0458-753-8221-D
We recommend STIHL 50:1 two-stroke engine
oil since it is specially formulated for use in
STIHL engines.
To ensure the maximum performance of your
STIHL engine, use a high quality 2-cycle engine
oil. To help your engine run cleaner and reduce
harmful carbon deposits, STIHL recommends
using STIHL HP Ultra 2-cycle engine oil or ask
your dealer for an equivalent fully synthetic 2-
cycle engine oil.
To meet the requirements of EPA and CARB we
recommend to use STIHL HP Ultra oil.
Do not use BIA or TCW (two-stroke water
cooled) mix oils!
Take care when handling gasoline. Avoid direct
contact with the skin and avoid inhaling fuel
vapour.
The canister should be kept tightly closed in
order to avoid any moisture getting into the mix‐
ture.
The fuel tank and the canister in which fuel mix is
stored should be cleaned from time to time.
11.1 Fuel mix ratio
Only mix sufficient fuel for a few days work, not
to exceed 30 days of storage. Store in approved
safety fuel-canisters only. When mixing, pour oil
into the canister first, and then add gasoline.
