DESCRIPTION
Safety equipment
The following equipment on the blower is
designed for protecting personnel and
materials. These components should
receive special attention whenever you
operate, inspect and service the blower.
Stop switch
• The stop switch (A) is used to stop the
engine.
1//_*
Muffler
• The muffler is designed to give the low-
est possible noise level and to direct the
engine's exhaust fumes away from the
operator. Mufflers fitted with catalytic
converters are also designed to reduce
harmful exhaust components.
• The engine exhaust fumes are hot and
can contain sparks, which may cause
fire if they come in contact with dry or
flammable material.
• Some blower models, especially those
sold in countries where the climate is
dry, are equipped with a spark arresting
screen (B). This screen must be cleaned
or replaced at specific intervals. See the
Maintenance section.

WARNING: The muffler is ex-
tremely hot while the engine is run-
ning and after it has stopped. DO
NOT TOUCH THE MUFFLER IF IT IS
HOT! This can cause severe burns.
Other equipment
Throttle trigger
• The speed and the output of the engine
are regulated by the throttle trigger (C).
/
C
Variable speed control
• The variable speed control (D) is de-
signed to allow setting engine speed as
necessary during blower use only.
/
• To avoid causing damage to the unit, DO
NOT attempt to use the variable speed
control during starting or during vacuum
use.
Fan housing
• The blower fan housing (E) and the fan
impeller (F) provide high performance air
discharge.

DESCRIPTION
Ground wire
• The ground wire (G) reduces static
build-up during operation in dry condi-
tions.

Inlet cover
• An inlet cover (H) is located on the side
of the fan housing. Opening this cover
allows access for cleaning and inspect-
ing the impeller (125Bx_sERIES and
125BVx_sERIES 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).

WARNING: Never start the blower I
if the inlet cover is not closed, is
damaged or cannot be closed
(except if the vacuum tube is fitted).
Cutters
(125Bx_sERIES and 125BVx_sERIES )
• Two cutters (J) are fastened to the impel-
ler. The cutters are there to mulch leaves
and other debris that have been vacuumed
before they enter the collection bag.
Blower tube and nozzle
NOTE: The tube clamp bolt and nut must
be installed prior to initial use (see the gen-
eral description of the blower on page 6).
• The blower tube (K) has a pegged slot
mounting system to the unit. To install or
remove the blower tube (or collection bag
tube for the 125BVx_sERES), the tube
clamp bolt must be removed. Align slot in
the blower air outlet with the raised rib on
the tube and insert tube until the holes in
the tube and housing align. Re-insert the
tube clamp bolt and tighten.
The nozzles (L) have 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
• The 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
• The 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
• The 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.

DESCRIPTION
Choke
• The choke (Q) is located below the air
filter cover and should be used every
time the engine is cold-started.
Adjusting the carburetor
NOT FOR ALL MODELS
•There are three adjusting screws (R) for
adjusting the carburetor:
• Low speed jet
• High speed jet
• Adjustment screw for idling
• Adjusting the carburetor involves adapt-
ing the engine to local operating condi-
tions, e.g. climate, altitude, gasoline and
type of two-stroke engine oil used. For
details about carburetor adjustment, see
the Maintenance section.
