To reduce the risk of
accidents and injuries,
always hold your saw
firmly with both hands:
Right hand on the control
handle, even if you are
left-handed. To ensure
safe control, wrap your
fingers tightly around
both handles.
One-handed operation is
particularly dangerous,
e.g. when cutting dry,
knotty and dead wood,
the chain may not enter
the cut properly. The
resultant reactive forces
may cause the saw to
skate or bounce on the
limb and slide out of con-
trol. This increases the
risk of serious or even
fatal injury.
Use the tree surgery chainsaw with one
hand only:
if two-handed cutting is not possible
–
and
if one hand is required for support
–
during the cut and
6
if the saw is held firmly and
–
if all parts of your body are clear of
–
the cutting attachment.
During one-handed cutting:
never support yourself on the limb
–
being cut
never cut with the bar nose
–
never attempt to hold falling limbs
–
Make sure you always have good
balance and secure footing. To avoid
slipping, take special care when the bark
is wet.
In the event of impending danger or in
an emergency, switch off the engine
immediately – move the Master Control
lever in the direction of STOP, 0 or †.
Never leave a running saw unattended.
Take special care in slippery conditions
– damp, snow, ice, on slopes, uneven
ground and freshly debarked logs.
Watch out for obstacles such as tree
stumps, roots and ditches which could
cause you to trip or stumble.
Do not work alone – keep within calling
distance of other persons trained in first
aid who can provide assistance in an
emergency. Helpers at the cutting site
must also wear protective clothing (hard
hat) and stand well clear of the branches
being cut.
Be particularly alert and cautious when
wearing hearing protection because
your ability to hear warnings (shouts,
alarms, etc.) is restricted.
To reduce the risk of accidents, take a
break in good time to avoid tiredness or
exhaustion.
The dusts (e.g. sawdust), vapor and
smoke produced during operation may
be dangerous to health. If dust levels are
very high, wear a suitable respirator.
When the engine is running: Note that
the chain continues to rotate for a short
period after you let go of the throttle
trigger (flywheel effect).
To reduce the risk of fire, do not smoke
while operating or standing near your
chainsaw. Note that combustible fuel
vapor may escape from the fuel system.
Check the saw chain at regular short
intervals during operation or
immediately if there is a noticeable
change in cutting behavior:
Shut off the engine and wait until the
–
chain comes to a complete
standstill.
Check condition and proper
–
mounting.
Check sharpness.
–
Do not touch the chain while the engine
is running. If the chain becomes jammed
by an obstruction, switch off the engine
immediately before attempting to
remove the obstruction – risk of injury.
Always shut off the engine before
leaving the saw unattended.
Shut off the engine before changing the
saw chain. This avoids the risk of injury
from the engine starting unintentionally.
To reduce risk of fire, keep hot exhaust
gases and hot muffler away from easily
combustible materials (e.g. wood chips,
bark, dry grass, fuel). Mufflers with a
catalytic converter can become
particularly hot.
