DESCRIPTION
SThe nozzles (
L
)ha
v
e a bayonet mount
for connection to the blower tube. Air is
channeled through the blower tube to the
nozzles, where the air discharge velocity
increases and the air stream discharge
pattern is formed to provide best perfor-
mance. The length of the blower tube
can be adjusted by twisting the nozzle to
the left to disengage the bayonet mount
and sliding the nozzle to the appropriate
position. Twist the nozzle to the right until
a click is felt to resecure the nozzle.
Starter device and starter handle
SThe starter device (M) is located on the
side of the engine shrouding and en-
gages the crankshaft only when the
starter handle (N) is pulled.
Fuel cap
SThe fuel cap (O) is located at the rear of
the engine shrouding on the fuel tank
and has a seal to prevent fuel from leak-
ing out.
Air filter
SThe air filter (P) consists of a fiber filter
medium in a resilient frame. The air filter
should be cleaned at specific intervals
(see Maintenance section). Otherwise,
the blower will consume too much fuel,
the performance will be reduced and an
oily deposit may form on the spark plug
electrodes.
Ground wire
SThe ground wire (G) reduces static
build--up during operation in dry condi-
tions.
Inlet cover
SAn inlet cover (H) is located on the side
of the fan housing. Opening this cover
allows access for cleaning and inspect-
ing the impeller (BV2126 only). If the
vacuum tube is used, it must be fitted to
the opening in the inlet cover. To open
the inlet cover, use a tool to lift the edge
of the cover
opposite the hinge (indicated by arrow
on inlet cover).
Cutters (BV2126)

FUEL HANDLING
Fuel mi
x
ture
CAUTION! The machine is equipped with
a two--stroke engine and must always be
run using a mixture of petrol and two--
stroke engine oil. It is important to accu-
rately measure the amount of oil to be
mixed to ensure that the correct mixture is
obtained. When mixing small amounts of
fuel, even small inaccuracies can drastical-
ly affect the ratio of the mixture.
Petrol
CAUTION! Always use a good quality
petrol/oil mixture (at least 90 octane).
Use low--emission petrol, also known as
alkylate petrol, if it is available.
SThe lowest octane recommended is 90.
If you run the engine on a lower octane
than 90, it can result in knocking. This
gives rise to a high engine temperature,
which can result in serious engine damage.
SWhen working at continuous high revs, a
higher octane rating is recommended.
Two--stroke oil
SFor best results and performance, use
JONSERED two--stroke oil, which is
specially formulated for our two--stroke
engines. Mixture 1:50 (2%).
SIf JONSERED two--stroke oil is not avail-
able, you may use another two-stroke oil of
good quality that is intended for air cooled
engines. Contact your dealer when select-
ing an oil. Mixing ratio 1:33 (3%).
SNever use two--stroke oil intended for
water--cooled outboard engines,
sometimes referred to as outboard oil.
SNever use oil intended for four--stroke
engines.
WARNING: Always ensure
there is adequate ventilation when
handling fuel.
S
A

before filling the machine’s fuel tank.
SDo not mix more than one month’s sup-
ply of fuel at a time.
SIf the machine is not used for some time,
the fuel tank should be emptied and
cleaned.
WARNING: The catalytic con-
verter muffler gets very hot during
and after use. This also applies
during idling. Be aware of the fire
hazard, especially when working
near flammable substances and/or
vapors.
Fueling
WARNING: Taking the following
precautions, will lessen the risk of

MAINTENANCE
Muffler
Some mufflers are fitted with catalytic con-
verters. See the Technical data section to
find out if your machine is equipped with a
catalytic converter.
The muffler is designed to dampen the
noise level and to direct the exhaust fumes
away from the user. The exhaust fumes
are hot and can contain sparks, which can
result in fire if the exhaust fumes are
directed towards a dry and flammable
material.
Some mufflers are equipped with a special
spark arresting screen (Y). If your machine
is fitted with this type of screen, it should
be cleaned regularly. To access the
screen, remove the outlet cover on the
front of the muffler. Use a wire brush to
clean the screen. On mufflers without a
catalytic converter the screen should be
cleaned weekly, or replaced if necessary.
On mufflers fitted with a catalytic converter
the screen should be checked and cleaned
monthly. If the screen is damaged it
should be replaced. If the screen is fre-
quently blocked, this can be a sign that the
function of the catalytic converter is im-
paired. Contact your dealer to inspect the
muffler. A blocked screen will cause the
engine to overheat resulting in damage to
the cylinder and piston.
Carburetor
Your Jonsered product has been designed
and manufactured to specifications that re-
duce harmful emissions. After the engine
has used 8--10 tanks of fuel, the engine will
be run--in. To ensure that it continues to run
at peak performance and to minimize harm-
ful exhaust emissions after the run--in peri-
od, ask your servicing dealer to adjust your
carburetor.
Function
SThe carburetor governs the engine’s
speed via the throttle control. Air and fuel
are mixed in the carburetor.
SThe T--screw (X) regulates the throttle
setting at idle speed. If the T--screw is
turned clockwise this gives a higher idle
speed; turning it counterclockwise gives a
lower idle speed.
Basic setting
SThe basic carburetor settings are ad-
justed during testing at the factory. Fine
adjustment should be carried out by a
skilled technician.
Recommended idle speed:
See “Technical data” section.
Recommended max. speed:
See “Technical data” section.
Fine adjustment of the idle speed--T
Adjust the idle speed using the idle adjust-
ment T--screw if it is necessary to readjust.
The idle speed is correctly adjusted when
the engine will run smoothly in every posi-
tion.
X
CAUTION! Never use a machine that has
a faulty or loose muffler. Ensure the muffler
bolts are tight.
Maintenance Safety
The owner is responsible for the perfor-

MAINTENANCE
Air filter
The air filter (CC) must be regularly cleaned
to remove dust and dirt in order to avoid:
SCarburetor malfunctions
SStarting problems
SLoss of engine power
SUnnecessary wear to engine parts
SExcessive fuel consumption
SElevated content of harmful exhaust
fumes.
Clean the filter every 25 hours, or more
regularly if conditions are exceptionally
dusty.
Cleaning the air filter
Remove the air filter cover (DD) and take out
the filter. Wash it clean in warm, soapy water.
Rinse thoroughly. Ensure that the filter is dry
before reinstalling it.
An air filter that has been in use for a long
time cannot be cleaned completely. The
filter must therefore be replaced with a new
one at regular intervals.
CAUTION! A damaged air filter must
always be replaced.
Cooling system
The engine is equipped with a cooling
system for maintaining the right operating
temperature.
The cooling system consists of the follow-
ing components:
1. Air intake on the starter device (Z).
2. Fan blades on the flywheel (AA).
3. Cooling fins on the cylinder (BB).
4. Cylinder cowling (guides cooling air flow
against cylinder surfaces).
Clean the cooling system by brushing once
a week, or more often, if necessary.
A dirty or blocked cooling system will
cause the blower to overheat and this will
damage the cylinder and piston.
WARNING: Mufflers fitted with
catalytic converters get very hot
duringuseandremainsoforsome
time after stopping. This also ap-
plies at idle speed. Contact can re-
sult in burns to the skin. Remember
theriskoffire!
WARNING: The inside of the
muffler contain chemicals that may
be carcinogenic. Avoid contact with
these elements in the event of a
damaged muffler.
WARNING: Bear in mind that:
Engine exhaust fumes contain car-
bon monoxide, which can cause
carbon monoxide poisoning. For
this reason you should not start or
run the machine indoors, or any-
where that is poorly ventilated.
The exhaust fumes from the engine
are hot and may contain sparks
which can start a fire. Never start
the machine indoors or near flam-
mable material!

MAINTENANCE
Spark plug
The spark plug condition is influenced by:
SIncorrect carburetor adjustment.
SAn incorrect fuel mixture (too much or in-
correct type of oil).
SPoor quality gasoline and/or oil
SA dirty air filter.
These factors cause deposits on the spark
plug electrodes, which may result in operat-
ing problems and starting difficulties.
If the machine is low on power, difficult to
start or runs poorly at idle speed: always
check the spark plug first before taking
any further action. If the spark plug is dirty,
clean it and check that the electrode gap is
0,6 mm. The spark plug should be replaced
after about a month in operation or earlier if
necessary. 0,6 mm
CAUTION! Always use the recommended
spark plug type! Use of the wrong spark
plug can damage the piston/cylinder.
Maintenance schedule
Below you will find some general mainte-
nance instructions.
Daily maintenance
SClean the exterior surfaces of the blower.
SCheck that the variable speed control and
the throttle trigger function in a safe man-
ner. Replace damaged parts.
SCheck that the stop switch works proper-
ly. Replace if necessary.
SClean the air filter. Replace if necessary.
SBV2126: Check that the inlet cover can
be locked in the closed position. Carefully
check that the fan impeller is clean, espe-
cially if the blower has been used for col-
lecting debris (vacuuming).
SCheck that all nuts and screws are prop-
erly tightened.
SCheck that all the housings are free of
cracks. Replace damaged parts.
SBV2126: Check that the collection bag is
intact and that the zipper works. Replace
it if necessary.
Weekly maintenance
SCheck the condition of the starter device,
the starter cord and the tensioning spring.
Replace damaged parts.
SCheck the condition of the air intake at
the starter device. Remove debris if it is
clogged.
SClean the outside of the spark plug. Re-
move it and check the electrode gap. Ad-
just the gap to 0,6 mm, or replace the
spark plug. Use resistor spark plug
Champion RCJ--8Y or equivalent.
SClean the fan blades on the flywheel.
SClean or replace the spark arresting
screen (not on mufflers with a catalytic
converter).
SClean the carburetor area.
SClean the air filter.
Monthly maintenance
SClean the fuel tank.
SClean the outside of the carburetor and
the area around it.
SClean the fan blades on the flywheel and
the area around it.
SCheck fuel lines for cracks or other dam-
age. Change if necessary.
SChange the fuel filter in fuel tank.
SCheck all cables and connections. Re-
place damaged parts.
SReplace the spark plug. Use spark plug
Champion RCJ--8Y or equivalent.
SChange the air filter.
