WARNING
Always check your power tool for proper
condition and operation before starting,
particularly the throttle trigger, throttle
trigger lockout, stop switch and cutting
attachment. The throttle trigger must
move freely and always spring back to
the idle position. Never attempt to
modify the controls or safety devices.
WARNING
Check fuel system for leaks, especially
the visible parts, e.g., filler cap, hose
connections, manual fuel pump (only for
power tools equipped with a manual fuel
pump). To reduce the risk of personal
injury or property damage from fire, do
not start the engine if there are leaks or
damage. Have the machine repaired by
a servicing dealer before using it.
WARNING
Never operate your power tool if it is
damaged, improperly adjusted or
maintained, or not completely or
securely assembled.
WARNING
Check that the spark plug boot is
securely mounted on the spark plug – a
loose boot may cause arcing that could
ignite combustible fumes and cause a
fire.
Keep the handles clean and dry at all
times; it is particularly important to keep
them free of moisture, pitch, oil, fuel mix,
grease or resin in order for you to
maintain a firm grip and properly control
your power tool.

For proper assembly of the bar and
chain follow the procedure described in
the chapter "Mounting the Bar and
Chain" of your instruction manual.
STIHL Oilomatic chain, guide bar and
sprocket must match each other in
gauge and pitch.
WARNING
Proper chain tension is extremely
important. In order to avoid improper
setting, the tensioning procedure must
be followed as described in your
manual. Always make sure the hex
nut(s) for the sprocket cover is (are)
tightened securely after tensioning the
chain. Check chain tension once more
after having tightened the nut(s). Never
start the pole pruner with the sprocket
cover loose.
Adjust carrying harness and hand grip to
suit your size before starting work.
Starting
To reduce the risk of serious personal
injury from fire, start the engine at least
10 feet (3 m) from the fueling spot,
outdoors only.
Your power tool is a one-person
machine. Do not allow other persons in
the general work area, even when
starting.
For specific starting instructions, see the
appropriate section of your manual.
Place the pole pruner on firm ground or
other solid surface in an open area or, in
the alternative, as shown in the above
picture. Maintain good balance and
secure footing.
WARNING
To reduce the risk of injury from loss of
control, do not attempt to "drop start"
your power tool. Drop starting means
pushing the machine away from the
operator, or allowing it to drop toward
the ground, while pulling on the starter
grip. This method is very dangerous
because you may lose control of the
machine.
WARNING
To reduce the risk of injury from loss of
control be absolutely sure that the guide
bar and chain are clear of you and all
other obstructions and objects, including
the ground, because when the engine
starts at starting-throttle, engine speed
will be fast enough for the clutch to
engage the sprocket and turn the chain.
Once the engine has started,
immediately blip the throttle trigger,
which should release the starting throttle
and allow the engine to slow down to
idle.
