SAFETY INSTRUCTIONS
MufflerThe muffler is designed to give the lowest
possible noise level and to direct the en-
gine’s exhaust fumes away from the opera-
tor. Mufflers fitted with catalytic converters
are also designed to reduce harmful ex-
haust components.
Safety equipment
The blower is equipped with a number of
safety devices and guards for the preven-
tion of accidents. These are described in
the general description of the blower.
The safety devices and guards also require
regular inspection and maintenance. These
measures and the interval at which they
should be carried out are specified in the
Maintenance section.
Safety while operating the
blower
S Do not allow bystanders or animals to be
in the work area, i.e. 50 feet (15 meters)
from the operator.
S The blower may throw objects at high
velocity that can ricochet and hit the opera-
tor. This may cause serious eye damage.
S Never point the blower nozzle toward
people or animals.
S Stop the engine before fitting or disman-
tling accessories or other components.
S Never operate the blower if any of the
guards are missing.
S Never operate the blower in poorly venti-
lated spaces where exhaust fumes might
otherwise be inhaled.
S Stop the engine before refueling. Move
the unit at least 10 feet (3 meters) from
fueling site before attempting to start.
S The catalytic muffler is extremely hot
while the blower is running and after it
has stopped. The same applies when the
blower is running at idling speed. Be
aware of the danger of fire, especially
while operating the blower near flam-
mable materials and/or where flammable
fumes are present.
Personal safety equipmentPersons who use the blower shall wear the
following safety equipment:
1. Approved ear protection.
2. Approved eye protection.
3. Approved protective gloves.

dusty environments.
Personal safetyThe following instructions apply to persons
operating the blower:
SThe operator shall have read and under-
stood the contents of this manual.
S Do not wear loose clothing, scarves or
neckchains or let long hair hang loose,
since these can be drawn into rotating
parts of the blower and cause injury.
S Do not operate the blower while under
the influence of alcohol, drugs or when
you are tired.
S Do not allow minors to operate the
blower.
S Always have a first aid kit nearby.
Fuel safety
Special safety instructions apply to the type
of fuel used for the blower. These instruc-
tions are specified under the Fuel handling
section.
WARNING:The fuel used to run
the blower has the following
dangerous characteristics:
1. Volatile liquid: its vapor and exhaust fumes are poisonous.
2. Direct contact can cause skin irritation.
3. It is extremely flammable.
WARNING:The exhaust fumes
from the engine are hot and may
contain sparks which can start a fire.
Never start the machine indoors or
near flammable material!
WARNING:Mufflers fitted with
catalytic converters become extreme -
ly hot during use and after stopping.
This also applies at idling speeds.
Contact can result in burns to the
skin.Beawareoftheriskoffire!
WARNING:The blower must
never be used if any of the safety
devices or guards are missing,
damaged or not in working order.

SAFETY INSTRUCTIONS
S Be careful, particularly if left hand opera-
tion is applied. Avoid any direct body con-
tact with inlet cover area. Keep jewelry,
loose clothing, or clothing with loosely
hanging straps, ties, tassels, etc., away
from inlet cover area.
S Do not operate the blower while standing
on a ladder or a stand.
Other safety measuresSOperate the blower only at reasonable
hours, i.e. not early in the morning or late
at night when people might be disturbed.
Comply with times listed in local ordi-
nances. Usual recommendations are 9:00
a.m. to 5:00 p.m., Monday through Satur-
day.
S Operate the blower at the lowest possible
throttle setting to do the job.
S Check the condition of the blower before
operation, especially the muffler, air intake
and air filter.
S Use a rake or a broom to loosen ground
debris before blowing.
S Under dusty conditions, slightly spray the
work area with a hose.
S Conserve water by using blowers instead
of hoses for many lawn and garden
applications, including areas such as roof
gutters, screens, patios and gardens etc.
S Watch out for children, pets, open windows
or vehicles, and blow debris safely away.
S Use the full nozzle extension so the air
stream can work close to the ground.
S After using the blower, clean up and
dispose of debris in trash receptacles.

DESCRIPTION
Safety equipmentThe 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 switchS The stop switch (A) is used to stop the
engine.
MufflerSThe 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.
S The engine exhaust fumes are hot and
can contain sparks, which may cause
fire if they come in contact with dry or
flammable material.
S 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 c leaned
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

Other equipment
Throttle triggerS The speed and the output of the engine
are regulated by the throttle trigger (C).
Variable speed controlSThe variable speed control (D) is designed
to allow setting engine speed as neces-
sary during blower use only.
S To avoid causing damage to the unit, DO
NOT attempt to use the variable speed
control during starting or during vacuum
use.
Fan housingSThe blower fan housing (E) and the fan
impeller (F) provide high performance air
discharge.

DESCRIPTION
Ground wireS The ground wire (G) reduces static
build-- up during operation in dry condi-
tions.
Inlet coverSAn inlet cover (H) is located on the side
of the fan housing. Opening this cover
allows access for cleaning and inspect-
ing the impeller ( 125B
X-- SERIESand
125BVX-- SERIESonly). 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(125BX-- SERIESand 125BVX--SERIES)
S 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).
S 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 125BV
X--SERIES), 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.
S 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 handleSThe 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 capSThe 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 filterSThe 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.
WARNING:Never start the blower
if the inlet cover is not closed, is
damaged or cannot be closed
(except if the vacuum tube is fitted).
