2.2 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 60,9 m.s
persons at a 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 ČSN EN 352-1 (shell-shaped ear protectors) or ČSN 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 ČSN EN 166 or ČSN 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

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

39 EN 12733 and ČSN 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.
40 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.
41 Short period = up to 1 minute.
