Taking Care of Guide Bar

groove
depth
A factory new machine should not be
run at high revs (full throttle off load)
for the first three tank fillings. This avoids
unnecessary high loads during the
break-in period.

6.0 mm (0.24")
If groove depth is less than specified:
As all moving parts have to bed in
during the break-in period, the frictional
resistances in the engine are greater
during this period. The engine develops
its maximum power after about 5 to 15
tank fillings.
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.
Do not make the mixture leaner to
achieve an apparent increase in
power - this could damage the engine
- see section "Adjusting Carburetor".

Note: Always disengage chain brake
before accelerating engine and before
starting cutting work. High revs with the
chain brake engaged (chain locked) will
quickly damage the powerhead and
chain drive (clutch, chain brake).
•
Turn the bar over - every time you
sharpen the chain - and every time
you replace the chain -
this avoids one-sided wear,
especially at nose and
underside of the bar.
Regularly clean

Measure groove depth -
with scale on filing gauge* -

in area used most for cutting
on Rollomatic bars.
