Preparation for the use of the pole
pruner
Take off the chain guard and inspect for
safety in operation. For assembly, follow
the procedure described in the chapter
"Mounting the Bar and Chain" of your
owner's 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.
Never start the pole pruner with the
sprocket cover loose. Check chain
tension once more after having
tightened the nut(s) and thereafter at
regular intervals (whenever the pole
pruner is shut off). If the chain becomes
loose while cutting, shut off the engine
and then tighten. Never try to tighten the
chain while the engine is running!

Fueling
Your STIHL pole pruner uses an oil-
gasoline mixture for fuel (see chapter
"Fuel" of your owner's manual).
!
Warning!
Gasoline is an extremely flammable fuel.
If spilled or ignited by a spark or other
ignition source, it can cause fire and
serious burn injury or property damage.
Use extreme caution when handling
gasoline or fuel mix.
To reduce the risk of fire or
burn injury, do not smoke
while using or standing
near the machine.
Combustible fuel vapor
may escape from the fuel
system.
Dust (e.g. wood dust), vapor (e.g. oil
mist from the chain lubricating system)
and smoke containing chemical
substances may be produced when
using this machine. These substances
may cause serious injuries and health
risks such as respiratory illnesses,
cancer, genetic defects or hereditary
damage.
If the risks associated with the possible
dust, vapor and smoke emissions are
not known, you should obtain the
relevant information from the contractor
or the responsible control body.
If it is not possible to avoid considerable
amounts of dust, vapor or smoke being
generated in spite of using the proper
working techniques, it is recommended
that the operator and bystanders wear
respirators approved for the substances
concerned.
Fueling Instructions
Fuel your pole pruner in well-ventilated
areas, outdoors only.
Always shut off the engine and allow it to
cool before refueling. Gasoline vapor
pressure may build up inside the gas-
tank of a two cycle engine depending on
the fuel used, the weather conditions,
and the venting system of the tank.
