To relieve vapor lock:
– Place the Choke Knob in the cold
start position g and pull the starter
cord approximately 20 times to clear
the vapor and send liquid fuel into
the carburetor.
– To start the power tool, move the
Choke Knob to the starting throttle
position e, set the slide control,
throttle trigger lockout and throttle
trigger to the starting throttle
position and pull the starter cord
approximately 10 times.
– If your power tool will not restart, or
if vapor lock occurs again, the
power tool is being used in
conditions too extreme for the fuel
being used. Discontinue use and let
the engine cool completely before
attempting to start the power tool.
Before Operation
Take off the chain guard (scabbard) and
inspect the pole pruner for proper
condition and operation. (See the
maintenance chart near the end of the
instruction manual.)
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). Do not start the engine if there
are leaks or damage – risk of fire. Have
the power tool repaired by a STIHL
servicing dealer before using it.
WARNING
Never operate your power tool if it is
damaged, improperly adjusted or
maintained, or not completely and
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 this 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.
For specific starting instructions, see the
appropriate section of your instruction
manual.
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.
