Chain tension and chain lubrication have
a significant impact on the service life of
the saw chain.
The saw chain is properly tensioned when
it does not hang from the underside of the
blade bar and cannot be moved around
by a gloved hand. When pulling on the
saw chain with 9 N (approx. 1 kg) of
force, the saw chain and blade bar should
not be separated by a distance of more
than 2 mm.

Risk of injury! Tension the
saw chain with the engine
switched off (after).
Tensioning the saw chain
1. Loosen the nut (48) of the sprocket cover
(49) with the mounting key (26).
2. Tension the saw chain (44) by turning
the screw (46) in a clockwise direction
with the screwdriver (27).
Reduce the saw chain tension by turning
the screw anti-clockwise.
3. Fix the sprocket cover (49) by tightening
the nut (48) with the mounting key (26).
The chain tension of a new saw
chain must be readjusted after a
maximum of 5 cuts.
Chain lubrication
The blade bar and saw chain must
never be operated without oil. If the
pruner is used with too little oil, the cutting
performance and lifespan of the saw chain
will decrease as the saw chain will
become blunt more quickly. You can
identify when there is too little oil if smoke
develops or the blade bar changes colour.
The oil flows to the blade bar as soon as
the engine starts operating.
Always turn off the device
and let the engine cool down
before filling with chain oil. Over-
flowing oil can cause a fire.
Filling with chain oil:
• Check the oil level indicator on the
oil tank (57) regularly and top-up the
oil if the minimum mark (58) "MIN" is
reached on the oil level indicator. The
oil tank holds about 120 ml of oil.
• Use bio-oil containing additives to re-
duce friction and wear. You can order
this from our service centre. Alternative-
ly, use chain lubricating oil with a low
proportion of adhesion additives.
• Empty the oil tank if it will not be used
for a prolonged period of time (6 - 8
weeks).
1. Unscrew the oil tank cap (56) and pour
the chain oil from the bottle (25) into
the tank.
2. Wipe off any spilled oil and close the
oil tank cap (56) again.
You can regulate the oil inflow
via the adjusting screw (59) on
the underside of the oil tank.
Swivelling out the cutter
bar
The cutter bar must be checked reg-
ularly for wear and reground. A
blunt cutter bar causes the device to over-
load. Any damage that results is not cov-
ered by the warranty.
