Starting and running
Starting and running
When the engine is started for the first time, car-
ry out the inspection points listed under First
start-up in the inspection schedule. See the In-
spection section.
Always check the following before running:
• oil level
• coolant
• fuel level
• electrolyte level in batteries
• state of charge of the batteries
• condition of the drive belt
• the level in the reductant tank, if the engine is
equipped with an SCR system.
Running the engine without reductant in the re-
ductant tank violates emissions legislation and
will damage the SCR system.
Checks before running
Carry out a daily inspection as described in the
inspection schedule prior to operation. See the
Inspection section.
Block the starting device when working on the
engine. If the engine starts unexpectedly, there is
a serious risk of injury.
Starting the engine
For environmental reasons the Scania engine has
been developed to be started with a low fuel feed.
Using unnecessarily large amounts of fuel when
starting the engine always results in emissions of
unburnt fuel.
1.
Open the fuel cock if fitted.
2.
Disengage the engine.
3.
If the engine has a battery master switch:
Switch on the power by means of the battery
master switch.
4.
Start the engine.
If the fuel tank has been run dry or if the engine
has not been used for a long time, bleed the fuel
system.
Never use starter gas or similar agents to help
start the engine. An explosion may occur in the
intake manifold with a risk of personal injury.
Only start the engine in a well ventilated area.
When the engine is run in an enclosed space,
there must be effective devices to extract exhaust
gases and crankcase gases.
The starter motor must only be cranked twice for
30 seconds at a time. After that, it must rest for at
least 5 minutes before the next attempt to start it.
Starting at low temperatures and at
high altitudes
Take the local environmental requirements into
account. Use a fuel heater and engine heater to
avoid starting problems and white smoke.
Scania recommends that an engine heater should
be used if the engine will be used at temperatures
below -10°C or at an altitude of more than 2,000
metres.
A low engine speed and a moderate load on a
cold engine limits white smoke, gives better
combustion and warms up the engine more
quickly than warming it up with no load.
Avoid running it longer than necessary at idling
speed.
