Operating Precautions
■ Make sure the chain and
sprocket are correctly adjusted
before operating the pruner
(see page 15 for adjustment
procedures). Never attempt
chain adjustment with the
engine running!
■ Always make sure the cutting
attachment is properly
installed and firmly tightened
before operation.
■ Never use a cracked or
warped guide bar: replace it
with a serviceable guide bar
and make sure it fits properly.
■ If a saw blade should bind fast
in a cut, shut off the engine
immediately. Push the branch
or tree to ease the bind and
free the blade.
■ Make sure there are no missing
or loose fasteners, and that the
ignition switch and throttle
controls are working properly.
■ Before starting the engine,
make sure the saw chain is
not contacting anything.
■ Make sure there is always
good ventilation when operat-
ing the pruner. Fumes from
engine exhaust can cause
serious injury or death. Never
run the engine indoors!
■ Do not operate the pole pruner
with the muffler removed.
■ When cutting a limb that is
under tension, be alert for
springback so that you will not
be struck by the moving limb.
■ Always stop the engine
immediately and check for
damage if you strike a foreign
object or if the unit becomes
tangled. Do not operate with
broken or damaged equipment.
■ Stop the unit immediately if it
suddenly begins to vibrate or
shake. Inspect for broken,
missing or improperly in-
stalled parts or attachments.
■ Never transport the pruner
nor set it down with the
engine running. An engine
that’s running could be
accidentally accelerated
causing the chain to rotate.
