Operations 5
NOTE
- If the engine fails to fire after two attempts,
follow the troubleshooting procedures outlined
in the engine manual.
- In case of extremely low ambient temperature,
follow the procedures outlined in the engine
manual.
- After cold starting the blockwage warning
indicator may light up, however, the indicator
will be switched off as the hydraulic oil reaches
normal temperature. Run the equipment at
low revs, and never at full power until the
indicator is switched off (4-8/36).
5.2.2 Winter operations
ATTENTION
If the ambient temperature is below 0° C, the
equipment must be "warmed up" to avoid damage
to specific components. While the engine is
idling, accentuate all the cylinders (lifting, tipping
and swivel cylinder) for some time (depending on
the ambient temperature).
The following tasks must be fulfilled to ensure trouble free
operations at low temperatures:
5.2.2.1 Fuel
At low temperatures paraffin precipitation can cause
blockages of the fuel system. Use winter diesel fuel
(suitable down to -15° C) at temperatures below 0°C.
NOTE
Winter diesel fuel is normally available from
refuelling stations in time for the cold season.
Often diesel fuels with additives are available for
use in ambient temperatures down to -20°C
(super-grade diesel fuel).
Add paraffin additives for temperatures below
-15°C or -20°C. Diagram (5-2) shows the required
quantities.
I = Summer diesel fuel
II = Winter diesel fuel
III = Super-grade diesel fuel
ATTENTION
Use only the fuel tank for mixing fuel! First fill in
the required amount of paraffin oil and then add
diesel.
