Operation safety

The machine is designed to protect its attendant from parts flying off the cut area. Do not remove any passive nor active safety elements. By doing so you
expose yourself to risk of injury.
2.2.1

Safety regulations


Machine attendants have to be aged 18 or over. The attendant must be familiar with the machine user manual and have knowledge of general
work safety principles.

Always switch off the engine and wait for the cutting disk to stop before starting any activity near the machine! Always switch the engine off before
leaving the machine!
 Never leave the engine running at the maximum engine speed or running idle for a long time while the clutches of the cutting disk drive and wheel
drive are turned off. The machine drive parts could be damaged (V-belt, belt pulley, clutch pulley, etc.)!
 Before each machine use check all its parts (especially the operating mechanism and its covers) to see if they aren't loose or damaged. Revealed
defects parts must be rectified immediately. For repairs, use the original spare parts only.

Remove any solid parts form the stand before cutting (such as stones, wires, loose construction leftovers, etc.), as these could be thrown away or
damage the machine. If these parts cannot be removed, avoid them.

The machine is equipped with a rotating implement. Maximum circumferential speed is 64 m.s
safe distance while the machine is operating (there is a possibility of the cut stand or solid objects chipping off)!

Since the recommended noise and vibration levels are exceeded, follow the following instructions when operating the machine:
a) Protect your ears with appropriate safety devices according to EN 352-1 (shell-shaped ear protectors) or EN 352-2 (plug ear protectors). Ask your
dealer for these safety devices.
b) After every 20 minutes maximum of operating the machine interrupt the work for a 10 minute break. During these breaks, the machine attendant
must not be exposed to other noise or vibrations.

When operating the machine, use work aids approved by EN 166 or EN 1731 (tight clothes, firm shoes, work gloves and protective glasses.) Keep
a safe distance form the machine given by its handlebars.

Do not start the engine in closed spaces! Pay special attention when handling the machine. The engine exhaust muffler remains hot after the engine
is switched off. While adding the fuel, make sure it does not leak or spill over engine parts. If the fuel is spilled, dry the soiled parts or wait for the fuel
to evaporate.


Any machine repairs, adjustments, greasing and cleaning is to be carried out when the machine is turned off and disconnected the spark
disconected.

40 ČSN EN 12733 and EN 12733 norms govern the specifications of the outer safety area A around the work area B. It is also necessary to use appropriate ban signs to prevent entrance into this
area. The distance between individual of A and B areas must not be smaller than 50m. As soon as a person or an animal enters the area, the machine attendant must immediately release the
cutting disk drive lever and postpone working until the area is clear again.
41 Do not use the machine on wet grass. Always work on safe terrain. Walk - never run - when working. Be careful, especially when changing directions on slopes. Do not cut stands on steep slopes.
If you fall, let the machine, go do not hold it.
