!Warning!
Always shut off the engine and ensure
that the chain is stopped before
undertaking any adjustments,
maintenance or repair work, changing
the saw chain or cleaning the pole
pruner. Do not attempt any maintenance
or repair work not described in your
Owner's Manual. Have such work
performed at your STIHL service shop
only.
!Warning!
Never test the ignition system with
ignition wire terminal removed from
spark plug or with unseated spark plug,
since uncontained sparking may cause
a fire.
!Warning!
To reduce the risk of fire and burn injury,
use only spark plugs authorized by
STIHL. Always press spark plug boot
snugly onto spark plug boot of the
proper size. (Note: If terminal has
detachable SAE adapter nut, it must be
attached.)
A loose connection between spark plug
boot and ignition wire connector in the
boot may create arcing that could ignite
combustible fumes and cause a fire.
Keep spark plug clean, and make sure
ignition lead is in good condition.
!Warning!
Do not operate your pole pruner if the
muffler is damaged, missing or modified.
An improperly maintained muffler will
increase the risk of fire and hearing loss.
Never touch a hot muffler or burn will
result. If your muffler was equipped with
a spark-arresting screen to reduce the
risk of fire (e. g. in the USA, Canada and
Australia), never operate your pole
pruner if the screen is missing or
damaged. Remember that the risk of
forest fires is greater in hot or dry
weather.
Keep the chain, bar and sprocket clean;
replace worn sprockets or chains. Keep
the chain sharp. You can spot a dull
chain when easy-to-cut wood becomes
hard to cut or burn marks appear on the
wood.
Keep the chain at proper tension.
Tighten all nuts, bolts and screws except
the carburetor adjustment screws before
each use.
Additionally, the daily maintenance
schedule for your pole pruner set forth in
your STIHL Owner's Manual should be
strictly followed.
Store pole pruner in a dry place and
away from children. Before storing for
longer than a few days, always empty
the fuel tank.
For any maintenance please refer to the
maintenance chart and to the warranty
statement near the end of this manual.
Store fuel and chain oil in approved and
properly labeled safety-type canisters
only. Take care when handling gasoline!
Avoid direct contact with the skin and
avoid inhaling fuel vapor!
