Saw chain oiling
Clean and oil the chain regularly.
This keeps the chain sharp and
achieves optimum machine perfor-
mance. Damage due to insuffi cient
maintenance of the saw chain will
invalidate the warranty. Remove the
battery and use cut-resistant gloves
when working with the chain or
with the blade bar.
The blade bar and chain must
never be operated without oil. If the
cordless garden pruner is used with
too little oil, the cutting performance
and lifespan of the saw chain will
decrease as the chain will become
blunt more quickly. You can identify
when there is too little oil if smoke
develops or the blade bar changes
colour.
Switch off the device and remove
the battery before carrying out any
maintenance work.
• Oil the chain after cleaning, after 10
hours of use or at least once a week,
whichever comes fi rst.
• Before oiling, the blade bar, especially
the teeth of the blade bar, must be thor-
oughly cleaned. Use a hand brush and
a dry cloth for this purpose.
• Oil the individual chain links using an
oil syringe with a needle tip (available
from specialist dealers). Apply individu-
al drops of oil on the joints and on the
tooth tips of the individual chain links.
Sharpening the saw chain
An incorrectly sharpened
saw chain increases the dan-
ger 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 cut-
ting tooth and a depth limiting projec-
tion. The vertical separation distance
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°)
- Apex angle (60°)
- Sharpness depth (0.65 mm)
- Round fi le diameter (4.0 mm)
Deviations from the meas-
urement data of the cutting
geometry can lead to an
increase of the spring-back
slope of the machine. In-
creased danger of accident!
Special tools are necessary for sharpening
the chain, which guarantee that the cutting
edges are sharpened at the correct angle
