7.6 Information about the spark plug
Check the spark plug regularly after 50 hours of
operation.
Removing the spark plug:
• Press the tab (22) of the spark plug cover (11)
and push the cover upwards.
• Disconnect the spark plug cap.
• Unscrew the spark plug and dry the electrodes.
When the spark plug has been removed or the
ignition cable has been pulled out of the plug cap,
the engine must not be moved. There is a risk of
fire through sparks.
Checking the spark plug:
• Clean spark plug with a dry cloth and check
electrodes. There must not be any dirt between
the electrodes. Brush dirt out with a thin
paintbrush if necessary.
• If the electrodes have been heavily worn away,
replace the spark plug immediately – otherwise
after 100 hours run.
• The correct electrode gap is 0.5 mm. If the
electrodes are bent and the electrode gap is
incorrect, replace the spark plug.
• Before starting work, check ignition cable for
perfect connection and insulation.
Spark plugs with resistor (thermal value 200) are
available in different brands under the following
description:
BOSCH WSR6F
CHAMPION RCJ-6Y or comparable.
Fitting the spark plug:
• Refit the spark plug and tighten using the
combination spanner (recommended torque if
using a torque spanner Î 22 Nm - 25 Nm).
• Push the spark plug cap firmly over the spark
plug.
• Place the spark plug cover on the casing, push
it downwards and snap it into place.
7.7 Replacing the fuel filter
We recommend having the fuel filter (34) changed
annually by a specialised service centre.
(schematic diagram)
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.
7.8 Shutdown and storage
Clean the power tool after use.
• Never use aggressive cleaning solutions or
those containing solvents to clean any part of the
engine. Never hose down the engine. For best
results, simply wipe down the entire engine with
a dry or slightly damp cloth.
• Clean and maintain the cutter.
We recommend: clean with "SOLO Universal-
Reiniger (Cleaner)" (Part no: 00 83 116) and treat
with "SOLO maintenance and care oil" (Part no:
00 83 163). Never use grease.
Store the device in a dry, safe location inside a
building (garage, basement, …). There must not be
any open fires or similar nearby. Ensure that the
device cannot be used by unauthorised persons,
especially children.
If not in use for more than four weeks, drain the
fuel tank in a well ventilated location before storing.
Start the engine with an empty fuel tank and drain
the carburettor until the engine stops. Oil residues
from the fuel mixture could otherwise clog the
carburettor jets and make it difficult to start the
device later.
