Refueling

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.
Only refuel the machine in a well ventilated

place. If fuel has been spilled, immediately clean

the machine – do not allow your clothes to be

splashed with fuel. If that happens, change your

clothes at once.

After fueling, tighten down the tank

cap as securely as possible.

This reduces the risk of unit vibrations causing

the fuel cap to loosen or come off and spill quan‐

tities of fuel.
Check for leaks. Do not start the engine if there

is a fuel leak – serious or fatal burns could result!

2.4

Before starting

Check that your power tool is properly assem‐

bled and in good condition – refer to appropriate

chapters in the instruction manual:

Check the fuel system for leaks, especially the

visible parts, e. g., fuel cap, hose connections,

manual fuel pump (only in machines with a

manual fuel pump). In case of leakage and

damage, do not start the engine – risk of fire!

Have the machine serviced by a dealer before

using it

The stop switch / slide control must be easy to

actuate

Smooth action of choke knob, throttle trigger

lockout, throttle set wheel and throttle trigger –

the throttle trigger must return automatically to

the idle position. The knob must spring back

from the warm start position 

g

 to the operat‐

ing position 

F

 when the throttle trigger lockout

and throttle trigger are pressed simultaneously

Rake and tines on the rake: All are correctly

mounted, secure and in good condition (clean,

not bent or cracked)

Check that the spark plug boot is secure – a

loose boot may cause sparking that could

ignite combustible fumes and cause a fire!

Do not make any changes to the controls or

the safety devices

Keep the handles dry and clean, free from oil

and dirt, for safe control

Adjust the harness to suit your height and

reach. Observe the chapter "Fitting the Har‐

ness"

To reduce the risk of personal injury, do not

operate your machine if it is not in a safe condi‐

tion.
To prepare for emergencies when using a har‐

ness: Practice setting down the machine quickly.

To avoid damage, do not throw the unit to the

ground when practicing.

2.5

Starting the engine

Start the engine at least 3 meters from the fuel‐

ing spot, outdoors only.
Place the machine on firm ground in an open

area. Make sure you have good balance and

secure footing. Hold the machine securely. The

rakes and tines must be clear of the ground and

all other obstructions because they may begin to

run when the engine starts – allow sufficient

clearance for movement of the rakes and tines.
Your power tool a one-person unit. To reduce the

risk of injury from fall falling branches or contact

with the rakes and tines, do not allow other per‐

sons within a radius of 5 meters of your own

position – even when starting.
To reduce the risk of injury, avoid contact with

the rakes and tines.
Do not drop-start the engine – start it as descri‐

bed in the User Manual.
Note that the rakes and tines continue to run for

a short period after you let go of the throttle trig‐

ger – flywheel effect!
Check idling engine: The rakes and tines must

not move when the engine is idling – with the

throttle trigger released.
To reduce the risk of fire, keep hot exhaust

gases and hot muffler away from easily combus‐

tible materials (e.g. wood chips, bark, dry grass,

fuel).

2.6

Holding and guiding the

machine

Always hold the unit firmly with both hands on

the handles. Make sure you always have good

balance and secure footing.
