Before starting the cut, accelerate the
engine up to full throttle. Perform cut
with uniform pressure. STIHL
recommends that the circular saw blade
be applied to the right of the tree, using
the non-shaded area of the blade, as
shown in the illustration above.
!Warning!
The risk of kickout is highest when
cutting in the darker shaded area. To
reduce the risk of kickout and resulting
injury, do not use this area of the circular
saw blade for cutting trees or shrubs.
Special techniques using the lighter
shaded areas of the blade to cut shrubs
and trees should only be used by
experienced operators with specialized
training in the use and control of the
trimmer/brushcutter.
!Warning!
To reduce the risk of loss of control and
serious injury to the operator or
bystanders by a kickout, never use a
circular saw blade on a trimmer/
brushcutter with a loop handle, but
rather only on one with a bicycle handle.
When felling small trees, maintain a
distance of at least two tree lengths from
the nearest coworker.
!Warning!
In order to reduce the risk of injury from
thrown objects or operator contact with
the blade or head, be sure to remount
the standard deflector when no longer
using a circular saw blade.
MAINTENANCE, REPAIR AND
STORING
Maintenance, replacement, or repair
of the emission control devices and
systems may be performed by any
nonroad engine repair establishment
or individual. However, if you make a
warranty claim for a component
which has not been serviced or
maintained properly or if
nonapproved replacement parts were
used, STIHL may deny coverage.
!Warning!
Use only identical STIHL replacement
parts for maintenance and repair. Use of
non-STIHL parts may cause serious or
fatal injury.
Strictly follow the maintenance and
repair instructions in the appropriate
sections of your instruction manual.
!Warning!
Always stop the engine and make sure
that the cutting attachment is stopped
before doing any maintenance or repair
work or cleaning the power tool. Do not
attempt any maintenance or repair work
not described in your instruction manual.
Have such work performed by your
STIHL servicing dealer only.
Wear gloves when handling or
performing maintenance on blades.
