N Turn the guide 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.
N Regularly clean the oil inlet hole (1),
the oilway (2) and the bar groove
(3).
N Measure the groove depth – with the
scale on the filing gauge (special
accessory) – in the area used most
for cutting.
If groove depth is less than specified:
N 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.
Removing the Shroud
N To switch off the engine, move the
Master Control lever in the direction
of STOP or † – when released, the
Master Control lever springs back to
the run position F.
N Push the hand guard forward – the
chain is locked.
N Open the twist locks (1) by turning
them 1/4 turn counterclockwise with
the combination wrench.
N Remove the shroud (2).
Installing the Shroud
N Place the shroud in position.
N Close the twist locks by turning
them a 1/4 turn clockwise.
