disconnected from the high-tension ignition cable.
A spark may cause a fire!
Spark plugs with resistor (thermal value 200) are
available in different brands under the following
description:
BOSCH WS6F
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.
• Fix the spark plug cover with the side tabs to the
corresponding grooves on the engine casing and
snap them into place on the engine casing.
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.
8.6 Information about the silencer
Ensure the silencer is in perfect condition before
operating the machine. Never touch the silencer
while it is still hot.
Unsatisfactory engine performance, despite a clean
air filter and a correctly adjusted carburettor, may
well be due to a partially blocked or damaged
silencer. Please consult your specialist service centre.
8.7 Replacing the fuel filter
We recommend having the fuel filter changed
annually by a specialised service centre.
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.
8.8 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).
• Clean and maintain the cutter.
We recommend: clean with "SOLO chainsaw/saw
cleaner" (Part no: 00 83 116) and treat with
"SOLO maintenance and care oil" (Part no:
00 83 163).
