Shift-time maintenance (STM) af-
ter each 10 hours of operation or
daily
Action 1. Oil level in the diesel engine
crankcase
Stop the engine, wait for 15 minutes and
check the oil level. The oil level shall be
between the upper and lower marks of
the probe (3). If necessary, take the cover
(2) of oil filler neck (1) away and fill oil up
to upper mark of the probe (3).
IMPORTANT! Do not fill up oil above
upper probe mark. Excessive oil will
burn, giving the fail impression of high oil
consumption for burning.
Action 2. Cooling fluid level in the
engine radiator
Remove the radiator cap away and check
the cooling fluid level, which shall be be -
low the upper edge of the filler neck (1)
by 50-6 0 mm. If necessary, add the cool -
ing fluid to the level.
IMPORTANT! Do not allow the level to
drop below 100 mm from the filler neck
upper edge.
WARNING! The engine cooling sys-
tem operates under pressure, which is
maintained by the valve in the radiator
cap. It is dangerous to take the cap
away from the hot engine. Let the en-
gine cool down, put some thick cloth
on the cap and turn it slowly to reduce
the pressure before removing the plug
fully. Beware of burns caused by hot
liquid!
