- After completing the cut, wait for the saw chain to stop before you move the chain saw.
Always stop the motor before moving from tree to tree.
2) Limbing
Limbing is removing the branches from a fallen tree.
When limbing leave larger lower limbs to support the
log off the ground.
Remove the small limbs in one cut as illustrated in
Figure (f).
Branches under tension should be cut from the bottom up to avoid binding the chain saw.
VI. MAINTENANCE AND STORAGE
WARNING - Before cleaning, inspecting or repairing the unit, switch off engine, let it cool
down and disconnect power cord plug from mains power source.
6.1- Saw Chain Sharpening
WARNING - It is very important for smooth and safe operation to always keep the cutters sharp.
- Be sure to wear safety gloves.
The cutters need to be sharpened when: - Sawdust becomes powder-like.
For non-experienced users of the chainsaw, we recommend to have the chain sharpened by a
specialist in any authorized service centre. Specialized resellers can carry out the chain sharpening.
It is interesting to entrust them with this task because of their sharpening technical knowledge and
speed. You may also find the sharpening tools to perform this task yourself in any specialized stores.
To sharpen the saw chain, use the suitable sharpening tools:
- Round chain file of 4,0mm
- File leading
- Chain measuring caliber.
To sharpen a chain, follow the instructions given in the leaflet accompanying the chain or sharpening
tools
Never work with a blunt or damaged saw chain. As a result of the work with a blunt or damaged saw
chain, there may appear huge physical tiredness, wrong cut and high chain wear.
To gain well shaped sawdust particles, use sharp chain. If there appears wooden powder, you
must sharpen the saw chain.
All cutting teeth must be similarly long.
Different length of the teeth can cause rough run
of the chain or its rupture, as well.
Minimum length of the teeth must be 4 mm. If
they are shorter, remove the saw chain.
Angles, which the teeth are under, must be
followed.
To sharpen the chain basically, make 2 to 3 pulls
of the file from the inside out.
When having wrong sharpened chain, a higher danger of kickback may occur.
f.
- You need extra force to saw in.
- The cut path does not go straight.
- Vibration increases.
