– Contact your local utility company
for information on cable and pipe
locations.
– Where necessary, confirm actual
location with cable detectors and/or
by carefully dug trenches.
Only use drilling tools and accessories
that are explicity approved for this power
tool by STIHL or are technically
identical. If you have any questions in
this respect, consult a servicing dealer.
Use only high 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.
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.

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.).
Wear sturdy shoes with non-slip soles.
Wear safety glasses or
other suitable eye protec-
tion. Wear hearing
protection, e.g. earplugs
or ear muffs.
Wear a safety hard hat where there is a
danger of head injuries from falling
objects.
Wear heavy-duty gloves.
STIHL offers a comprehensive range of
personal protective clothing and
equipment.
Transporting the Power Tool
Always turn off the engine.
Remove the auger before transporting
the power tool long distances. To
reduce the risk of burn injury, carry
the unit by the handle frame with hot
parts of the machine (e.g. gearbox)
away from your body.
Transporting in a vehicle: Properly
secure your power tool to prevent
turnover, fuel spillage and damage.
Fueling
Gasoline is an
extremely flammable
fuel. Keep clear of naked
flames. Do not spill any
fuel – do not smoke.
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.
After fueling, tighten
down the screw-type fuel
cap as securely as
possible.
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 seri-
ous 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.
