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
64 m.s
-1
. It is therefore important to keep other 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
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.
When the machine is being operated, all other persons (
especially children
) and animals must stay out of the machine's workspace. The machine attendant can
only continue working after taking these into a safe distance.
It is forbidden to remove any protective devices and covers from the machine.
Safe
climbing ability of the machine is 10º. Maximum engine tilt while working is 20º for long and 30º for short periods
35
.
Any machine repairs, adjustments, greasing and cleaning is to be carried out when the machine is turned off and disconnected the spark disconected.
