PRUNING
See figure 11
Pruning is the process of removing limbs from a standing tree.
·
Using the chainsaw like a lever, push the guide bar (10) against the limb at full speed.
·
First, make a relief cut (40) on the compression side (bottom).
·
Then make a bucking cut (41), offset in the direction of the trunk, on the tension side (top).
DELIMBING
See figure 12
Delimbing is the process of removing limbs from a felled tree (30).
·
Leave the larger bottom limbs in place so that the trunk is not resting on the ground.
·
Remove small branches in one cut.
·
Remove tensioned branches from bottom to top.
·
Use the larger bottom branches as support until the trunk is cut (31).
BUCKING A LOG
see figures 13 to 15
Bucking is the process of cutting a log into lengths (38). Make sure you have a firm footing and keep your balance at all times. If it is possible, life the log and hold it with branches, logs or
chocks.
·
If the log is held along the entire length (32), cut it starting at the top (33).
·
If the log is supported at one end (34),
o
in a first cut, remove 1/3 of the diameter from the bottom (35);
o
in a second cut, start cutting from the top (36) to finish the bucking.
·
If the log is supported at both ends (37),
o
in a first cut, remove 1/3 of the diameter from the top (36);
o
cut lower in a second cut, 2/3 from the bottom (35), to finish the bucking.
·
If the log is on a slope,
o
Stand on the uphill sound (39);
o
Control the chainsaw;
o
Hold the handles tightly;
o
Release the cut pressure near the end of the cut;
NOTE
Do not let the chain touch the ground.
When bucking is complete,
·
Release the switch trigger (5).
·
Stop the chainsaw entirely.
·
Move to the next tree with the chainsaw.

GENERAL MAINTENANCE AND CARE
WARNING
To avoid serious injuries during cleaning or to carry out other maintenance work, always remove the battery from the tool first.
CAUTION
Never allow brake fluids, petrol products based on oils, etc. come into contact with plastic parts. Chemicals can damage, weaken or destroy plastic, which can lead to serious injuries.
CAUTION
Do not use strong solvents or cleaning agents on the plastic housing or the components.
SETTING THE CHAIN TENSION
see figure 2 to 7
The more that you use a chain, the longer it becomes. It is therefore important to configure the chain regularly to reduce slack.
Tighten the chain as much as possible, but not so tight that you cannot pull it off by hand.
