quality parts and accessories in order to
avoid the risk of accidents and damage
to the machine.
STIHL recommends the use of original
STIHL replacement parts. They are
specifically designed to match your
model and meet your performance
requirements.
Never attempt to modify your power tool
in any way since this may increase the
risk of personal injury. STIHL excludes
all liability for personal injury and
damage to property caused while using
unauthorized attachments.
Do not use a pressure washer to clean
the unit. The solid jet of water may
damage parts of the unit.
Clothing and Equipment
Wear proper protective clothing and
equipment.
Avoid clothing that could get caught on
branches or brush or moving parts of the
machine. Do not wear a scarf, necktie or
jewelry. Tie up and confine long hair
(e.g. with a hair net, cap, hard hat, etc.).
Warning!
A face shield alone does not
provide adequate eye protection.
Wear hearing protection, e.g. earplugs
or ear muffs.
Transporting the Power Tool
Always stop the engine.
Carry the unit suspended from the
harness.
Transporting in a vehicle: Properly
secure your power tool to prevent
turnover, fuel spillage and damage.
Fueling
Always shut off the engine before
refueling.
Do not fuel a hot engine –
fuel may spill
and cause a fire
.
Open the fuel cap carefully to allow any
pressure build-up in the tank to release
slowly and avoid fuel spillage.
Fuel your power tool only in well-
ventilated areas. If you spill fuel, wipe
the machine immediately – if fuel gets on
your clothing, change immediately.
This reduces the risk of unit vibrations
causing the fuel cap to loosen or come
off and spill quantities of fuel.
Check for leakage. To reduce the
risk of
serious of fatal burn injuries
, do not
start or run the engine until leak is fixed.
Before starting
Check that your power tool is properly
assembled and in good condition – refer
to appropriate chapters in the instruction
manual.
Clothing must be sturdy
but allow complete free-
dom of movement. Wear
snug-fitting clothing, an
overall and jacket combi-
nation, do not wear a
work coat.
Wear steel-toed safety
boots with non-slip soles.
Wear a safety hard hat
where there is a danger
of head injuries from fall-
ing objects. Wear a face
shield and safety
glasses.
Wear heavy-duty gloves,
preferably made of
leather.
