Oil container
Check the oil level in the oil container. Both befo-
re and during your work make sure that there is
always suffi cient oil in the system. To avoid dama-
ging the chainsaw, never run the saw if there is no
oil in the system or if the oil drops below the „min"
mark. On average, a single fi lling will last around
15 minutes depending on the number of pauses
in cutting and the loads involved.
Chain
Check the tension of the saw chain and the
condition of the cutting elements. The sharper
the chain, the easier and more controllable it is
to operate the chainsaw. The same also applies
to the chain tension. For greater safety you must
check the chain tension before your work and at
least every 10 minutes during your work. New
chains in particular tend to expand more.
Safety clothing
Always wear appropriate tight-fi tting safety
clothing such as special trousers which protect
against cuts, protective gloves and safety shoes.
Hearing protection and protective goggles.
Wear a protective helmet with integral face and
hearing protection. This will off er protection
against falling branches and recoiling branches.
Safe working
•
To ensure that you can work in safety you
must use the equipment at a working angle of
max. 60° (Fig. 15).
•
Never stand under the branch you want to
saw.
•
Use special caution when working with bran-
ches under tension and splintering wood.
•
Possible risk of injury caused by falling bran-
ches and catapulting pieces of wood.
•
When the equipment is in operation, keep
other persons and animals away from the
danger zone.
•
The equipment is not protected from electric
shock through contact with high-voltage
cables. Keep a minimum distance of 10 m
from live cables. Electric shock can cause
fatal injury.
•
When working on slopes always stand to the
upper or left or right side of the branch you
want to cut.
•
Hold the equipment as close as possible to
your body. This will help you to keep your ba-
lance.

Cutting techniques

•
When removing branches, hold the equip-
ment at an angle of max. 60° to the horizontal
to avoid being hit by a falling branch (fig. 15).
•
Start with the bottom branches on the tree.
This will make it easier for the cut branches to
drop.
•
After completing a cut, the weight of the saw
will abruptly increase for the operator as the
saw is no longer supported by the branch.
This can result in you losing control over the
saw.
•
Remove the saw from the cut only with the
saw chain still running. This will prevent the
saw from getting jammed.
•
Never cut with the tip of the saw.
•
Never cut into the bulging branch collar. This
will prevent the tree from healing.
Sawing off smaller branches (Fig. 13):
Place the contact surface of the saw onto the
branch. This will prevent the saw from making
jerky movements when you begin a cut. Exerting
slight pressure, guide the saw from the top to the
bottom through the branch.
Sawing off large and long branches (Fig. 14):
Carry out a relief cut when working on large bran-
ches.
Start by sawing through 1/3 of the branch diame-
ter (a) from the top to the bottom with the top side
of the cutter rail. Then saw towards the fi rst cut (b)
from the top to the bottom with the bottom side of
the cutter rail.
Saw off long branches in several steps to keep
control over the impact location.
Kick-back
The term „kick-back" describes what happens
when the running chainsaw suddenly kicks up-
ward and backward. Usually this is caused by
contact between the tip of the cutter bar and the
workpiece or by the saw chain becoming trapped.
In the event of kick-back, large forces occur
suddenly and violently. As a result, the chainsaw
usually reacts uncontrollably. This can often result
in very serious injuries to the worker or persons in
the vicinity. The risk of kickback is at its greatest
when the saw is positioned for a cut in the region
of the tip of the cutter bar, as the leverage eff ect is
greatest there. It is therefore safest to position the
saw as fl at as possible.
