Tensioning the saw chain
Regularly tightening the saw chain pro-
vides safety for the user and reduces and/
or prevents wear and chain damages.
Before the start of work and in approx. 10
minute intervals, we recommend the user
to examine the chain tension and correct
it, if necessary.
The chain warms up when working with
the saw and thus expands slightly. These
“expansions” can be expected especially
from newer chains.
Do not re-tighten or change the
chain when it is hot because it
shrinks slightly once it has cooled
down. In case of non-observance,
this can lead to damages on the
guide rail or the engine because
now the chain is too taut on the
blade. Chain tension and chain lu-
brication have a significant impact
on the service life of the chain.
The chain is correctly tensioned if it does
not sag at the rail underside and can be
rotated completely around with the gloved
hand. When the saw chain is tensioned
with 9 N (approx. 1 kg), the gap between
the saw chain and the guide rail may not
be more than 2 mm.
10 min
1. Ensure that the chain brake has
been released, that is, that the
chain brake lever (3) is pulled up
against the front grip (16).
2. Unscrew the fastening bolt (7)
(
).
3. To tighten the saw, turn the chain
adjustment ring (8) clockwise.
To loosen the tension, turn the
chain adjustment ring anti-clock-
wise.
4. Tighten up the fastening bolt (7)
again (
).
With a new saw chain, you must
readjust the chain tension after at
least 5 cutting operations.
Chain lubrication
The rail and chain must never be
without oil. If you operate the elec-
tric chainsaw with too little oil, the
cutting performance and the lifetime
of the saw chain is reduced, since
the chain becomes blunt faster. You
can identify a case of too little oil
where smoke development or dis-
coloration of the rail occurs.
As soon as the motor is speeded up, the
oil also flows faster to the chain bar
(
4).
Filling up with chain oil:
• Check the oil level indicator ( 21)
regularly and top-up the oil if the mini-
mum mark „MIN“ ( 22) is reached
on the oil level indicator. The oil tank
holds about 280 ml of oil.
• Use bio-oil; this product contains ad-
ditives that reduce wear and tear and
does not damage the pump system.
bio-oil is available from our Service-
Center.
• If you have no Grizzly Tools bio-oil
available, use chain lubrication oil with
low adhesive additive content.
• Empty the oil tank before longer peri-
ods (6-8 weeks) of non-use.
