8.4 Maintenance of the chain brake
Check for ease of movement and correct operation on a daily basis.
Remove any resin, sawdust and dirt
.
Grease should be applied to all visible joints and
bearings approximately once a week (indicated with
arrows in the diagram)
For improved access ! activate the chain brake
Chain brake function test (chapter 3.9).
8.5 Vibration damping
If you find that vibrations on the handles worsen significantly with time in comparison to when the
chainsaw was new, check the damping elements (rubber-bonded metal mountings) for damage and
replace them as required.
Working with the chainsaw while the vibration damping system is not working properly can
cause health problems.
8.6 Spark plug information
The spark plug should be regularly checked every 50 operating hours.
• Take off the cowl from the chainsaw. (chapter. 3.4)
• Disconnect the spark plug connector which is located underneath.
• Unscrew the spark plug and dry it thoroughly.
In the event of severe burn-off of the electrodes the spark plug should be replaced immediately,
otherwise every 100 hours.
The engine must not be moved if the spark plug is removed or the ignition cable is
disconnected. Otherwise there is a risk that sparks could form which might cause a fire.
Interference-suppressed replacement spark plugs (calorific value: 200) are
available for example under the following trade names:
BOSCH WSR6F, CHAMPION RCJ-6Y or equivalent.
The prescribed electrode gap is 0.5 mm.
Before starting work, check the ignition cable to make sure the connections are in good working order
and the insulation is intact.
• Screw the spark plug back in again.
• Always press the spark plug connector firmly onto the spark plug.
• Refit the cowl to the chainsaw.
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.
