Gas, dust and flammable vapours
Do not operate combustion engines in environments that may
contain flammable gases or vapours. These gases, dusts or
vapours could ignite or be drawn in by the intake system, which
could cause the engine speed to increase or the maximum engine
speed to be exceeded. This may cause fire, explosion, or serious
property damage. It might also become impossible to switch off
the engine.
Signals and signs from the signalman
 Set up signs to warn of slopes and soft ground. If the visibility
is not good, position a signalman if necessary. Operators
should pay careful attention to the signs and follow the
instructions from the signalman.
 Only one signalman should give signals.
 Make sure that all workers understand the meaning of all sig-
nals and signs before starting work.
Emergency exit
The door on the right side of the operator's cab can be used as
an emergency exit in case of danger.
