NOTICE
The chain must always be coated with a
film of lubricant.
The manual pump (arrow) provides
additional chain lubrication in special
situations:
– Cutting for long periods with extra
long bars
– At low temperatures
– After a long out-of-service period
– Before starting
This helps protect the cutting attachment
from excessive wear.
N Flip the bar – after each sharpening
and each time the chain is changed
– to avoid uneven wear, especially
at the sprocket nose and on the
bottom
N Periodically clean the oil inlet
hole (1), oil outlet channel (2) and
bar groove (3)
N Measure groove depth – using the
measuring tool on the file gauge
(special accessory) – in the area
with the greatest wear
