Before using
banging or ringing may be heard coming from the engine. This is normal and does not indicate a problem.
In the event that the banging or ringing noise occurs during normal load and at standard engine speeds,
change the type of petrol used. If problem is not rectifi ed after this change, please contact an authorised
service centre.
When running the engine at high speed over an extended period, we recommend the use of a petrol with
a higher octane number.
CHECKING THE HAND GUARD
The hand guard prevent the hand from coming into contact with the moving blades, for example in
a situation when the user of the user's hand slips from the front handle.
ATTENTION!
Check that the hand guard is correct seated and attached.
Check the hand guard for damage.
CHECKING THE BLADES
To ensure good work results, it is important
that there is correct contact pressure between
the trimmer blades. Contact pressure is set by
turning the bolt on the underside of the guide bar
clockwise.
When the blades are correctly set, the give
between the blades measured at the bolts must
be 0.2 - 0.4 mm.
In the event that the trimmer blades are bent or
damaged, replace them.
Check the working edges of the blades and if
necessary, adjust them using a fl at and round fi le.
1. Maintain a sharp end edge on the blade (Fig.
2). The best working angle of the blade is 45°.
2. Round the base of the blade.
3. Do not use water when fi ling.
