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.
Your power tool comes standard with
either a screw-type or bayonet-type fuel
cap.
This reduces the risk of unit vibrations
causing the fuel cap to loosen or come
off and spill quantities of fuel.
Before starting
Check that your power tool is properly
assembled and in good condition – refer
to appropriate chapters in the instruction
manual.
– Check operation of chain brake,
front hand guard
– Correctly mounted guide bar
– Correctly tensioned chain
– Smooth action of throttle trigger and
throttle trigger interlock – throttle
trigger must return automatically to
idle position.
– Master Control lever / stop switch
must move easily to STOP or 0
– Check that the spark plug boot is
secure – a loose boot may cause
arcing that could ignite combustible
fumes and cause a fire.
– Never attempt to modify the controls
or the safety devices in any way.
– Keep the handles dry and clean –
free from oil and pitch – for safe
control of the chain saw.
To reduce the risk of personal injury,
do not operate your saw if it is damaged
or not properly assembled.
Starting the engine
Start the engine at least 3 meters from
the fueling spot, outdoors only.
Place the unit on firm ground in an open
area. Make sure you have good balance
and secure footing. Hold the unit
securely. The cutting attachment must
be clear of the ground and all other
obstructions because it may begin to run
when the engine starts.
Your chain saw is designed to be
operated by one person only. Do not
allow other persons in the work area –
even when starting.
To reduce risk of chain rotation and
personal injury, lock the chain with the
chain brake before starting.
Do not drop start your machine – the
correct starting procedure is described
in the instruction manual.
Do not attempt to start the saw when the
saw chain is in a cut.
Holding and Controlling the Power
Tool
Always hold your saw firmly with both
hands: Right hand on the rear handle,
even if you are left-handed. To ensure
safe control, wrap your fingers tightly
around the front and rear handles.
During Operation
Make sure you always have good
balance and secure footing.
Gasoline is an
extremely flammable
fuel. Keep clear of naked
flames. Do not spill any
fuel – do not smoke.
After fueling, tighten
down the screw-type fuel
cap as securely as
possible.
Insert the fuel cap with
hinged grip (bayonet-type
cap) correctly in the
opening, turn it clockwise
as far as stop and fold the
grip down.
