: 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:
: Press down the throttle trigger
interlock and set Master Control
lever to cold start l
: Turn twist lock above the rear
handle 90° to left (counter-
clockwise).
: Lift off shroud vertically.
