Daily Checks of the Engine
(Fig. 20) Lubrication System
It is of utmost importance to use correct lubri-
cating oil types, in accordance with the load
placed on the engine. See Lubrication Table
under ”Maintenance”. Check the oil level daily
before starting; it shall be between the mini-
mum and maximum marks on dipstick A,
preferably near the maximum, fig. 20. Oil is
refilled through filler B. Symbol on the iqan
monitor indicates low oil pressure. Should the
oil pressure warning light come on with the
engine running, stop the engine immediately
and find the cause for the trouble.
Cooling System
The engine cooling system is filled with coolant that has 40-50 % ethylene glycol in it. Do not
use plain water as coolant as it damages the engine. Before refill, the engine must cool off. When
refilling, remember the coolant expands considerably when it gets warm, so do not fill up the
system. The coolant level is correct when the cells are clearly covered by the coolant, and the
coolant level can be seen at the bottom of the level indicator hose of the expansion tank. Check
the coolant level daily before starting.
The coolant temperature can be seen on the iqan monitor. It shall be between 75-95oC. A warning
symbol on the iqan monitor indicates engine overheating when the temperature reaches 95oC.
If the temperature starts to rise, check that the outside of the radiator is not clogged. The best
way to clear blockage is to direct compressed air from the side of the fan through the radiator,
or use a brush for cleaning. Always be careful not to damage the lamellas. Behind the cooler
course mesh filter there is a small-holed screen. To clean it, first turn the rear cog to its down
position and then lift up the screen.
Crane side tilt automation
An automatic stabilizer function is available for the crane side tilt as an optional feature. It helps
keep the crane in an upright position even if the machine itself is tilted sideways on a slope. This
automatic function can be switched on from the side instrument panel. If the side tilt is used
manually, the automatic stabilizer function is disengaged. The automatic stabilizer can be re-
engaged by pressing the side tilt vertical straightening button on the joysticks. The same button
must also be pressed after starting the diesel engine. This is to avoid accidental movements that
the driver may not notice.
