COMMISSIONING, STARTING AND STOPPING

There is a separate manual for the engine. The engine may be started and operated only
in an area with good ventilation. Indoors and in other closed areas the exhaust gases
must be piped outside.
Before starting the engine make sure that all the controls are in their neutral positions
and the safety lever is in back position (controls are not activated). Make sure the main
switch is activated. The machines supplied for cold climate are equipped with engine
and hydraulic oil heaters. Use the heaters prior starting the engine.
6.2.1

STARTING ENGINE

• Before starting engine, read engine operator's manual
carefully.
• Turn the ignition switch to position I and wait 30 sec and
until engine signal lights are off.
• Turn the ignition switch to position III until the engine
starts and then release it.
• Do not crank the engine for more than it is said in the engine
operator's manual.
• The engine oil pressure signal light goes off when the
engine is running and none of the filter indicators should be
on.
• If the warning lights keep a longer period on, stop the
engine, check for reason.
• Normally, the signal light of return filters can be on for 1 to
5 minutes after starting the engine (if the temperature of the
hydraulic oil is lower, the period is longer).
• When the engine is running at idle the pressure gauges for
the hydraulic oil in the instrument panel should show low
pressure in the system if no function is being used.
n NOTICE
Do not rev up the engine while it is cold.
Do not operate the hydraulics while the oil is cold.
While the engine is warming up direct the heater vents to remove any fog on the
windows and check the head and working lights. Test the horn.
It is important that the temperature of the hydraulic oil reaches 40 °C before operating
the engine at full rpm and applying hydraulic loads. You should operate all the
hydraulic functions without load in order to get the warm oil in cylinders and drives.
Therefore when the engine has warmed up, start using all the functions slowly. This acts
also as a check that everything is in working order.
Check the temperature and pressure gauges on the instrument panel during the normal
operation. Prior to stopping the engine, follow the instructions for storing the machine.
