Fuel cap
After fueling, tighten
down the screw-type fuel
cap as securely as
possible.
This helps reduce the risk of unit
vibrations causing an incorrectly
tightened fuel cap to loosen or come off
and spill quantities of fuel.
Before starting
Check that your power tool is properly
assembled and in good condition,
especially if it has been subjected to
unusually high loads for which it was not
designed (e.g. heavy impact or a fall).
Check the fuel system for leaks,
–
especially the visible parts, e. g.,
fuel cap, hose connections, manual
fuel pump (only in machines with a
manual fuel pump). In case of
leakage and damage, do not start
the engine – risk of fire! Have the
machine serviced by a dealer
before using it
The setting lever must move easily
–
to STOP or 0
Throttle trigger must move freely
–
and spring back by itself to the idle
position
Check that the spark plug boot is
–
secure – a loose boot may cause
sparking that could ignite
combustible fumes and cause a fire!
Check the fuel system for leaks

Check the condition and tightness
–
of container, hose and metering unit
Check condition of harness straps
–
and replace damaged or worn
straps
To reduce the risk of accidents and
personal injury, do not operate your
power tool if it is not properly assembled
and in good condition.
For emergencies: Practice quickly
opening the fastener on the waist belt
(special accessory), loosening the
shoulder straps and setting down the
unit. To avoid damage, do not throw the
unit to the ground when practicing.
Starting the engine
Start the engine at least 3 meters from
the fueling spot, outdoors only.
Your power tool is designed to be
operated by one person only. Do not
allow other persons in the work area –
even when starting.
Always proceed as described in the user
manual.
Place the machine on level ground only,
ensure that you have a secure footing
and hold the machine securely.
If an assistant is required to put the
power tool on your back, make sure that
the engine is running at idle speed
–
the assistant is not standing in the
–
area of the exhaust outlet and
breathing exhaust fumes
the valve lever and, on SR 450 only,
–
the metering lever is closed
the assistant is not standing in the
–
area of the outlet nozzle
the assistant leaves the work area
–
immediately after you have put the
power tool on your back
Holding and guiding the machine
Carry the power tool on your back with
both harness straps – do not hang it over
one shoulder. Hold and control the
blower tube with your right hand on the
control handle – even if you are left-
handed.
Work only slowly, moving in a forwards
direction – always observe the discharge
area of the blower tube – do not move
backwards – risk of tripping!
Keep the power tool and container
upright. To avoid the risk of chemical
leaking from the container and causing
injury,do not bend forwards.
