English
: Turn the bar over –
every time you sharpen the chain
and every time you replace the
chain – this helps avoid one-sided
wear, especially at the nose and
underside of the bar.
: Regularly clean
the oil inlet hole (1),
the oilway (2) and
the bar groove (3).
: Measure groove depth –
with scale on filing gauge* – in area
used most for cutting.
* see “Guide to Using this Manual”
If groove depth is less than specified:
: Replace the guide bar.
The drive link tangs will otherwise
scrape along the bottom of the groove –
the cutters and tie straps will not ride on
the bar rails.
Dirty air filters reduce engine power,
increase fuel consumption and make
starting more difficult.
If there is a noticeable loss of
engine power
: Move the Master Control lever (1)
to the normal run position.
: Loosen knob (2) in direction of
arrow.
: Remove the carburetor box
cover (3).
: Clean away loose dirt from around
the filter.
