F-550
2.2 Safe operation
The machine is designed to protect the user against flying parts of mowed brush as much as possible. Do not remove any active or
passive safety element. Doing so shall expose you to injury or harm.
2.2.1 Safety instructions
The machine operator must be 18 years or older. He/she must read through the machine operating manuals and adhere to
general work safety precautions.
When operating the machine, use work equipment approved according to
EN 166
or
EN 1731
(close-fitting apparel, sturdy
footwear, work gloves and protective goggles). Keep a safe distance from the machine, given by the handle.
All surrounding persons
(especially children)
and animals must be in safe range of the machine operating space. The operator
may continue working after ensuring that they are located at a
safe
distance.
Before every use of the machine
, check to ensure that no component (particularly working assembly or covers) are not loose
or damaged.
Any discovered defects must immediately be removed
. Use only original replacement parts when repairing.
The mowed vegetation must first be cleared of solid objects (such as rocks, wires, free construction remnants, etc.), which could
be ejected or which could damage the machine, prior to machine use. If they cannot be removed, avoid these locations.
Do not start the engine in enclosed areas! Use increased caution when handling the machine. The muffler is hot after the engine
is turned off. Be careful to avoid spillage onto engine parts when refilling fuel. If spillage occurs, dry the affected parts or wait
until the gasoline evaporates.
The machine is equipped with a rotating operating tool. The maximum peripheral speed is
54 m.s
-1
. It is therefore important to
ensure that others remain at a safe distance when the machine is in operation (possible ejection of mowed vegetations or hit
solid objects)!
Safe
climbing availability of the machine is 10°. The maximum tilt of the engine during long-term operation is 20°, in short-
term
operation 30°.
Never let the engine running at maximum speed or idling for long periods, with the blade drive clutch and wheel drive clutch
turned off! This could result in damage to the drivetrain components (V-belt, pulley, clutch pulley, etc.)!
Always turn off the engine and wait until the operating tool stops, before engaging in any activity near the machine! Always turn
the engine off before leaving the machine!
Removal of protective devices and machine covers is prohibited.
Any repairs, adjustments, lubrication, and cleaning of the machine must only be performed when the machine is off and with the
spark plug cable disconnected.
Since the noise and vibration reference values are exceeded, the following instructions must be followed when operating the
machine:
Hearing should be protected with suitable protective equipment according to
EN 352-1
(
ear muffs) or
EN 352-2
(
protective ear plugs). This equipment should be available at your local retailer.
Every 20 minutes of machine operation should be interrupted by at least 10 minutes of rest. The operator must not be
exposed to other sources of noise or vibration during these rests.

standards modify the limitations of external safety area A around operating area B. Meanwhile, suitable restriction labels will prevent entry into this area. The distance
between individual sides of areas A and B must not be less than 50 m. As soon as a person or animal enter this hazardous machine area, the operator must immediately release the
drive lever of the cutting device and wait until the area is again free.

Do not use the machine on moist grass. You must always move along safe terrain. Operate while walking, never while running. Be particularly careful when changing directions on
slopes. Do not cut on steep slopes. In the event of a fall, do not hold onto the machine, but instead release it.
