10.5.1 General notes on safety
DANGER
Risk to life
When carrying out repairs, remove the vehicle from the
danger zone of passing traffic and wear reflective clothing.
DANGER
Risk of injury due to engine overrun. Once the engine has
been switched off, wait for 5 seconds. Stay well clear of the
working area for this time.
Risk of injury when vehicle accidentally starts up. Remove
the ignition key and disconnect the battery prior to perform-
ing cleaning and maintenance tasks on the vehicle.
Be careful when using high-pressure cleaners for cleaning!
Do not directly point the high-pressure jet to electrical com-
ponents, tyres, radiator fins and hydraulic hoses.
When cleaning the appliance with a high pressure cleaner,
adhere to the respective safety instructions.
Maintenance on the hydraulic system must only be carried
out by trained personnel.
Danger
Risk of injury! While carrying out maintenance tasks, tilt the
waste container fully upward and lower the brush system/
attachment to remove the pressure from the hydraulic sys-
tem.

Risk of injury due to inadvertently lowering waste contain-
er. Prior to working underneath the waste container, move
the waste container all the way into the emptying position.

Risk of injury due to inadvertently lowering waste contain-
er. Only perform work on the turbine while the waste con-
tainer is completely lifted (for sweepers).

rying out any maintenance and repair work.
Do not touch any hot parts, such as the drive motor and ex-
haust system.

10.5.3 Safety notes regarding the batteries
Please observe the following warning notes when handling
batteries:
Observe information
in the user manual of
the battery and on
the battery as well as
in these operating in-
structions!
Wear an eye shield!
Keep away children
from acid and batter-
ies!
Risk of explosion!
Fire, sparks, open
light, and smoking
not allowed!
DANGER
Follow accident prevention regulations as well as DIN VDE
0510, VDE 0105 T.1.
Risk of explosion! Do not put tools or similar on the battery,
i.e. on the terminal poles and cell connectors.
Risk of injury! Ensure that wounds never come into contact
with lead. Always clean your hands after having worked
with batteries.
Risk of fire and explosion!
– Smoking and open flames must be strictly avoided.
– Rooms where batteries are charged must have good
ventilation because highly explosive gas is emitted dur-
ing charging.
Danger of causticization!
– Rinse thoroughly with lots of clear water if acid gets into
the eye or comes in contact with the skin.
– Then consult a doctor immediately.
