z Fire coming from hydraulic line
Check that all the hose and tube clamps, guards, and cush-
ions are securely fixed in position.
If they are loose, they may vibrate during operation and rub
against other parts. This may lead to damage to the hoses,
and cause high-pressure oil to spurt out, leading to fire dam-
age or serious injury.
z
Explosion caused by lighting equipment
 When checking fuel, oil, battery electrolyte, window
washer fluid, or coolant, always use lighting with anti-
explosion specifications. If such lighting equipment is not
used, there is danger of explosion that may cause seri-
ous injury.

When taking the electrical power for the lighting from the
machine itself, follow the instructions in this manual.
Action if fire occurs
If a fire occurs, escape from the machine as follows.
z
Turn the start switch OFF to stop the engine.
z Use the handrails and steps to get off the machine.
Window washer liquid
Use an ethyl alcohol base washer liquid.
Methyl alcohol base washer liquid may irritate your eyes, so do
not use it.
ROPS (Roll Over Protective Structure)
z The roll-over protection system (ROPS) protects the opera-
tor and absorbs load and impact energy, if the machine
should roll over.
z The ROPS is a fixed component of the cab. The machine
must not be operated without this roll-over protection sys-
tem.
z The ROPS meets the regulations of all member states of the
EU. If, however, the ROPS is modified, damaged, or
repaired without permission, its stability is impaired. In this
case, the ROPS must be replaced, since its correct function
can no longer be guaranteed.
z
The ROPS can only provide maximum protection, if the
driver wears the safety belt correctly. For this reason, the
safety belt is to be worn when the machine is in operation.
