- Prevent fuel spillages. Close the fuel tank by hand and test the entire tank for leaks. It is advisable
to drain the tank before carrying out any work.
Regularly service this machine. Only carry out those maintenance jobs and repairs, which are
described in this manual. A specialised service centre will carry our all other jobs.
For any repairs only use original parts from the manufacturer.
Do not modify, alter or change the machine as this may impact on the safe operation of the machine
and may lead to accidents and injuries!
1.4 Fuelling
•
•
•
•
•
•
•
•
•
•
•
Petrol is very light and highly flammable. Keep away from open flames and never spill fuel. Do
not smoke at the operating site or at and near the refuelling site!
Stop the engine prior to refuelling.
Let the engine cool down before refuelling - fire risk!
Open the tank lid slowly to allow any excess pressure in the tank to be reduced without the risk of
petrol spraying out.
Fuel may contain substances similar to solvents. Prevent products made from mineral oil coming into
contact with skin and eyes. Wear protective gloves during filling with fuel. Frequently change and clean
protective clothing.
Avoid breathing in fuel vapour.
The refuelling site should be well ventilated.
Avoid any soil spillage of fuel or oil (protection of the environment). Use a suitable mat.
Immediately clean any spilled fuel on the machine. Change contaminated clothing without delay.
Firmly tighten all tank lids. This will reduce the risk of spillage from lids, which have become loose from
engine vibrations.
Check for petrol leaks. Do not start the machine or work with the machine if there is a petrol leak. Life
threatening risk from burns!
Store fuel and oil in approved and correctly labelled containers.
1.5 When transporting the equipment
•
•
•
Always turn off the engine when transporting the machine.
To prevent fuel running out and associated damages, secure the equipment against tipping over
during vehicle transportation. Check the tank for leaks. It is advisable to drain the tank before
transportation.
Drain the tank before despatching the equipment.
1.6 Preparing the equipment for starting
Check the complete machine for operational safety.
• The stop switch should function properly.
• The throttle must have freedom of movement and return to the idle position on its own accord.
• The impeller and the blower casing must be in a problem-free condition. Damage to the blower casing
can lead to an injury hazard through escaping foreign objects. In this case do not use the device, have
it checked by a dealer
• Ensure the spark plug cap and the ignition cable are connected firmly. A loose connection may cause
a spark, which can ignite any existing fuel:air mixture - fire hazard!
Should the check reveal any irregularities or recognisable damage (also to the frame), incorrect
adjustments or reduced efficiency of the machine, do not commence work. Take the power tool to a
specialised workshop and have it checked.

motor turns over.
In that case we recommend you proceed as follows:
• Remove the spark plug cover.
• Pull the spark plug cap off the spark plug.
• Remove the spark plug and dry fuel mixture from
the electrodes.
• Move the throttle lever up to full throttle. Pull the
starter handle several times (with removed spark
plug) to clear the combustion chamber.
• Move the throttle lever down to idling position, refit
the spark plug, the plug cap and the plug cover.
• Start the engine with the choke lever down ( )
and the stop switch in the "I" position.
8.5 Turning off the engine:
Release gas throttle, and if required bring the pre-gas
selector switch into idle position. The stop switch is
placed in pos. “0”.
Emergency stop Should the engine – due to a faulty
ON / OFF switch – fail to stop, it can also be stopped
by closing the choke (choke lever in position ). After
such an event, do not restart the engine, but have the
equipment checked by an authorised service shop.
9. Using
9.1 Blower operation - Fig. 1
The device is designed as a one-hand device. It can
be carried with the right hand or also the left hand on
the operating handle.
Leaves, grass cuttings, shavings, grains can be
blown away - even on uneven terrain.
Through lower engine RPMs the strength of the
blower jet can be lessened and the effective area can
be reduced.
Watch for small animals!
9.2 Vacuum operation – only model 441 (with
model 440 as accessory) - Fig. 2
8.4 Engine will not start:
The vacuum shredder is conceived as a two-hand
device. It must be carried with the right hand on the
pedestal grip and with the left hand on the operating
handle. The carrying strap of the collection bag is
placed over the left shoulder and the right arm goes
through the carrying strap.
With the vacuum tube leaves, grass clippings, pieces
of cardboard, pieces of bark etc. can be vacuumed
up.
The suction force can be reduced by lower RPM
speed and the effective area can be decreased.
Always watch out for small animals when vacuuming.
If the motor does not start in idle position (ON/OFF
switch (1) on "I“?), press the throttle (2) half-way
down and bring the gas selector lever (3) into a
middle position. Do not start with throttle fully open! If
the motor still does not start, then the combustion
chamber is flooded.
Attention:
When vacuuming wet leaves or clumps of grass the
blower can become plugged! Before opening the
blower cover - even to remove clumped or jammed
suctioned material - always place the stop switch on
"0" and pull off the sparkplug connector!
8.3 When the motor starts:
Adjust the gas pre-selector switch (3) all the way up
(idle position) if you had it on a middle position. You
can now start working. The ideal RPM speed can be
set either with the gas throttle or the gas pre-selector
switch.

Operating and maintenance instructions
10. Operating and maintenance
instructions
10.1 General operating and maintenance
instructions
The maintenance and the repair of modern machines
as well as their safety-relevant assemblies require
qualified specialised training and a workshop
equipped with special tools and test equipment.
Consequently the manufacturer recommends that all
tasks not described in these operating instructions be
carried out by a specialised workshop. That
specialist has the required training, experience, and
equipment at his disposal, to provide you with the
most cost-effective solution for such work. He will
provide additional help in word and deed.
After a running-in time of app. 5 hours, all accessible
screws and nuts (except the carburettor adjusting
screws) must be checked for tightness and they must
be retightened, if required.
Bear in mind when using this power tool that the
engine and its various components such as
carburetor and ignition system can become very hot,
particularly at full-throttle operation. So that no
consequential damages occur in this regard, the
motor should run for some time in idle after longer
periods of full-throttle operation. When you are
finished with the work, let the motor cool down.
It is best to store the equipment in a dry, safe
location with a full fuel tank. There should be no
open flame or similar nearby. For longer periods
without using the equipment (longer than four
weeks), see chapter "10.7 Shutdown and storage".
Turn the idling end-stop screw "T" to adjust the idling
speed in accordance with the details provided in the
specification. Use an engine rev counter for this job.
•
If the idling speed is too high, turn the idling endstop screw "T" anti-clockwise.
•
If the idling speed is too low (engine stops) turn
the idling end-stop screw "T" clockwise until the
engine runs smoothly.
If the idling speed cannot be set correctly with the
idling end-stop screw "T", request an authorised
service centre to tune the carburettor.
The following instructions are for authorised
service shops
Use the D-CUT carburettor key to adjust the idle
mixture screw "L" and the full load mixture screw "H".
Clean the air filter before adjusting the low speed
screw!
Let the engine run warm before adjusting the engine
speed.
The carburettor is tuned for optimum engine
performance. Use a rev counter to tune the
carburettor correctly!
Do not adjust the engine to a higher speed.
Excessive engine speed can lead to major engine
damage!
10.3 Information about the spark plug
Check the spark plug regularly after 50 hours of
operation.
Fig. 14
10.2 Carburettor adjustment
The carburettor has been adjusted optimally at the
factory. Subject to the operational altitude
(mountains or low lying areas), the carburettor may
require readjustment.
Fig. 13
The carburettor has 3 adjusting screws:
• Idling end-stop screw "T"
• Low speed mixture screw "L"
• High speed mixture screw "H"
Only qualified mechanics must adjust the regulating
screws for idle mixture "L" and full load mixture "H".
ENGLISH 14
• Push in tab (30) on the standard equipment casing
and push out spark plug cap (8).
• Disconnect the spark plug cap.
• Unscrew the spark plug and dry the electrodes.
The spark plug should be replaced after 100 hours of
operation or if the electrodes are badly worn.
Do not turn the engine over while the spark plug has
been removed or the spark plug cap has been
disconnected from the high-tension ignition cable. A
spark may cause a fire!
Operating and maintenance instructions
Spark plugs with resistor (thermal value 200) are
available in different brands under the following
description:
BOSCH
WSR6F
CHAMPION
RCJ-6Y or comparable.
The correct electrode gap is 0.5 mm.
Only use spark plugs, where the contact nut has
been firmly fitted. Loose connectors may produce
sparks, which can cause a fire.
• Insert the spark plug into the cylinder head and
tighten it.
• Push the spark plug cap firmly over the spark plug.
• Push the spark plug cover back on again and lock
with tab (30).
Before restarting the engine, check the high-tension
ignition cable for any damage to its insulation and
ensure the cable is connected securely to the plug
cap.
10.4 Air Filter Maintenance
Dirty air filters cause a reduction in engine
performance and increase fuel consumption with
more pollutants in the exhaust gas. Engines are less
likely to start readily with a dirty and soiled air filter.
The following maintenance jobs should be carried
out frequently.
Fig. 15
Fig. 16
Remove the assembled filter element (36) from the
filter retainer (37). Please note: Never separate the
filter element
Please note: Never separate the filter element. Clean
the filter more often in extreme dust conditions. For
daily cleaning jobs simply tap the filters against a
hard object or use compressed air. Damaged air
filters should be replaced immediately. Warranty does
not apply to engine damage caused by the lack of or
improper maintenance.
Insert the new or cleaned filter element in accordance
with Fig. 16 into the filter retainer. Then close the filter
cover and secure it by clicking it into position.
Never insert moist or wet filter elements!
10.5 Replacing the fuel filter
We recommend having the fuel filter (40) changed
annually by a specialised service centre.
Fig. 17
Before opening the air filter, close the choke
to
prevent dirt entering the carburettor.
Press clip (35), tilt and remove the filter cover (11).
Clean around the filter.
A trained mechanic can carefully remove the fuel filter
via a wire loop through the fuel tank filler. Ensure that
the thicker part of the fuel hose on the tank wall is not
drawn into the fuel tank.

Implement all maintenance jobs regularly. If required, authorise a specialist service centre to maintain the
machine for you. The owner of the machine is responsible for:
• Any damage caused by a lack of maintenance, incorrect or late maintenance and repairs
• Consequential losses - including corrosion - from incorrect storage
10.7 Shutdown and storage
Preferably, store the equipment in a dry and secure place with a full fuel tank. Open flames or similar must not
be nearby. Prevent unauthorised use – particularly by children.
For stops longer than four weeks the following steps should be carried out:
• Empty and clean the fuel tank at a well-ventilated location.
• Start the engine with an empty fuel tank. Run the engine until the carburettor is empty and the engine stalls.
Otherwise the carburettor nozzles could become encrusted with residual fuel mixture and make a
subsequent start harder.
• Clean the power tool well (particularly the air intake openings, the cylinder fins, the air filter and the fuel filler
area).
