Stihl MS 391 Safety Manual page 5

Wear safety boots –
with cut-retardant mate-
rial, non-slip soles and
steel toe caps
Wear a hard hat – if
objects could fall on you.
Wear safety glasses or
a face shield and "per-
sonal" hearing
protection – e.g., ear
defenders.
Wear heavy-duty, non-
slip gloves – preferably
made of leather.
STIHL can supply a comprehensive
range of protective clothing and
equipment.
Transporting the chain saw
Always engage the chain brake and
attach the chain scabbard – even before
transporting the saw for short distances.
When transporting the saw for longer
distances (more than approx. 50 m),
also stop the engine.
Always carry the saw by the handlebar –
with the hot muffler away from your
body, the guide bar must point to the
rear. Avoid touching hot parts of the
machine, especially the surface of the
muffler – risk of burns!
In vehicles: When transporting in a
vehicle, properly secure your machine to
prevent turnover, damage and fuel
spillage.
Chain Saw Safety Manual
Refueling
Gasoline is an
extremely flammable
fuel – keep clear of
naked flames and fire –
do not spill any fuel – no
smoking.
Switch off the engine before refueling.
Never refuel the machine while the
engine is still hot – the fuel may spill over
– risk of fire!
Open the filler cap carefully so that any
excess pressure is relieved gradually
and fuel does not splash out.
The machine may only be refueled in a
well ventilated place. Clean the machine
immediately if fuel is spilled. Change
your clothes immediately if they are
contaminated with fuel.
A number of different filler caps are
installed as standard at the factory.
Close the filler cap as
tightly as possible after
refueling.
Place the cliplock filler
cap (bayonet-type) in
position, turn it until it will
go no further and fold the
cliplock down.
This helps reduce the risk of unit
vibrations causing an incorrectly
tightened filler cap to loosen or come off
and spill quantities of fuel.
Before starting
Check that saw is properly assembled
and in good condition - refer to
appropriate chapters in the Instruction
Manual:
– functional chain brake, front hand
guard
– Correctly mounted guide bar
– Correctly tensioned chain
– The throttle trigger and throttle
trigger interlock must move easily –
throttle trigger must return
automatically to the idle position
when released.
– Master control/stop switch must
move easily to STOP or 0
– Check that the spark plug boot is
secure. A loose boot can lead to
flying sparks which may ignite the
escaping fuel/air mixture – risk of
fire!
– Never attempt to modify the controls
or safety devices
– Keep the handles dry and clean –
free from oil and pitch – for safe
control of the chain saw.
The chain saw should only be used if it
is in full working order – risk of
accident!
Starting the engine
Move at least 3 meters away from the
place at which the machine was refueled
and never in enclosed spaces.
