Oiling The Saw Chain; Sharpening The Saw Chain - Grizzly Tools EKS 2240 QTX Traduction De La Notice D'utilisation Originale

Oiling the saw chain

Clean and oil the chain regularly. In
this way, you keep the chain sharp
and get optimum machine perfor-
mance. In case of damage due to
inadequate maintenance of the saw
chain, the guarantee claim is invalid.
Remove the power plug and use
cut-protection gloves when you are
handling the chain or the chain bar.
• Oil the chain after cleaning, after 10
hours of use or at least once weekly,
depending on which comes first.
• Before oiling, the chain bar must be
cleaned thoroughly, in particular the
teeth of the rail. Use a whisk and a dry
cloth for that.
• Oil the individual chain links with the
aid of an oil suction gun with pinpoint
tip (available in the specialist trade).
Place individual oil drops onto the ar-
ticulated links and onto the tooth tips
of the individual chain links.

Sharpening the saw chain

An incorrectly sharpened saw
chain increases the danger of
spring-back! Use cut-protection
gloves when you are handling
the chain or the chain bar.
A sharp chain guarantees an op-
timal cutting performance. It eats
effortlessly through the wood and
leaves large, long wooden chips.
A saw chain is blunt if you have
to press the cutting equipment
through the wood and the wooden
chips are very small. In the case
of a very blunt saw chain, no chip
cuttings result at all, only sawdust.
• The sawing parts of the chain are
the cutting elements, which consist
of a cutting tooth and a depth limiting
projection. The vertical separation dis-
tance between these two determines
the sharpness depth.
• The following values must be noted in
sharpening the cutting teeth:
- Sharp edge angle (30°)
- Breast angle (85°)
- Sharpness depth (0.65 mm)
- Round file diameter (4.0 mm)
Deviations from the measure-
ment data of the cutting geom-
etry can lead to an increase of
the spring-back slope of the
machine. Increased danger of
accident!
Special tools are necessary for sharpen-
ing the chain, which guarantee that the
cutting edges are sharpened at the cor-
rect angle and to the correct depth. For
the inexperienced user of chainsaws,
we recommend to have the saw chain
sharpened by a specialist or a specialist
workshop. If you think yourself capable of
sharpening the chain, you can acquire the
special tools in the specialist trade.
1. Switch the saw off and unplug it from
the mains.
2. Remove the saw chain (refer to the
section on operating the saw). The
chain should be well-tensioned to en-
sure proper sharpening.
3. For the sharpening, a round file with
4.0 mm diameter is necessary.
